Description

Analog multi effector and its operation method to increase sound effect

The present invention relates to an electronic device used in the instrument, and more particularly, to an analog multi-effector (Analog Multi-Effector) that can be used together with the electric guitar to modulate and expand the sound of the electric guitar and its operation method will be.

Various kinds of effectors are used to modulate the tone of an electric guitar. These effects are devices that produce different sound effects by changing electric signals such as human voices, musical instruments, and video images, which can be classified into analog and digital methods. In the case of the effector used for playing the guitar, the latter has the advantage of being easy to use but has the disadvantage of poor sound quality. Therefore, in recent years, the analog effector, which is equivalent to the former, is mainly used in the field where electric guitar is used. The analog effector controls On / Off by playing the foot switch while the player is playing. It is common to use a plurality of these effects in combination. If all of these effects are turned on, a modulated tone can be obtained by combining a plurality of effects, and some effects are turned on, and the rest are turned on. When the effect is turned off, the turned off effect is bypassed and the tone is modulated by a combination of only the turned on effects. When playing an electric guitar, the player generally uses a plurality of tones even within the same song, and one of these tones is used by a combination of a plurality of effectors.

For example, in the case of arpeggios or strokes, a combination of effects such as Chorus, Delay, Reverbe, etc. is used to obtain a Clean Tone, and a rock music feeling is produced. In the case of backing, the combination of effects such as distortion, overdrive and heavy metal is used, and when special effects are required, flanger and phaser are used. Use a combination of effects such as.

On the other hand, it is very difficult for a player to produce the above combination by operating a large number of footswitches while playing, and analog multi-effects for guitars have already been developed to set the effect combination in advance.

1 is a block diagram illustrating another analog multi-effector according to the prior art.

Referring to FIG. 1, an analog multi-effector 20 is provided in the center for modulating and extending the input signal 21 of the guitar 1 and sending it to the amplifier 2 through the output signal 22. A plurality of effectors 10 are connected to the analog multi-effector 20 through send (Send, 24) and return (Return, 25) signals, respectively.

The player is configured to turn on / off the plurality of effectors 10 through one foot switch 23.

The analog multi-effector according to the prior art first requires a large number of cables in order to connect a plurality of effectors, which causes a problem in that installation and use are inconvenient and cost increases. In addition, since a plurality of effectors and analog multi-effectors each take the configuration of a separate finished product, there is a problem in that transportation and storage are inconvenient because the volume is too large and the weight is high.

An object of the present invention is to reverse the direction of transmission of a sound signal in a specific module by relay control of the sound signal input through an input signal, and in a specific module, the sound signal is serially and in parallel. It is to provide an analog multi effector that can generate various sound effects by processing.

Another object of the present invention is to reverse the direction in which sound signals are transmitted from a specific module by relay control of the sound signals input through the input signals, or to transmit the sound signals in a specific module in series. It is to provide a method of operating an analog multi-effector that can produce a variety of sound effects by processing in parallel.

Analog multi-effector which can increase the sound effect according to an aspect of the technical idea of the present invention is a box-shaped analog multi-effector main body is designed to expand the function of the circuit board is built in the outside and the outside; A plurality of cable connection parts provided on the side of the analog multi-effector body, a plurality of modules provided on an upper surface of the analog multi-effector main body and having an LED lamp and an operation switch installed thereon to indicate an operation state of the corresponding module; A plurality of channels provided on an upper surface of the analog multi-effector main body, having a function of programming and operating the plurality of modules, and having an LED (LED) lamp and an operation switch installed to indicate an operation state of a corresponding channel; Is provided on the upper surface of the effector body and in which Characterized in that it comprises a station signal transmission operation switch which is capable of promoting effort signal transmission in the opposite direction.

According to a preferred embodiment of the present invention, the analog multi-effector is provided on the upper surface of the analog multi-effector main body further comprises a parallelized operation switch that can proceed in a serial manner in parallel to the acoustic signal transmission of a specific module in the module in the module. It can be provided.

In this case, the reverse signal transfer operation switch and the parallelization operation switch, it is preferable that the LED lamp indicating the operation state of the operation switch is provided adjacent to.

On the other hand, it is preferable that the reverse signal transfer operation switch and the parallelization operation switch operate by relay control of a circuit board embedded in the box-shaped analog multi-effector main body. It is suitable to transfer signals between two modules in a plurality of modules in reverse, and the paralleling operation switch is suitable for transferring signals between two modules in parallel in the plurality of modules.

According to another aspect of the present invention, there is provided a method of operating an analog multi-effector capable of increasing an acoustic effect, comprising: preparing an analog multi-effector capable of increasing an acoustic effect as described above; Connecting a corresponding cable, transmitting a sound signal in a first direction in a plurality of modules of the analog multi-effector, and in a predetermined two of the plurality of modules, a sound signal in a direction opposite to the first direction; Characterized in that the step of passing in two directions.

Preferably, the step of transmitting the sound signal in the second direction is suitably performed by relay control of a circuit board embedded in the analog multi-effector main body.

According to another aspect of the present invention, there is provided a method of operating an analog multi-effector capable of increasing an acoustic effect, comprising: preparing an analog multi-effector capable of increasing an acoustic effect as described above; Connecting a corresponding cable, transmitting a sound signal in series in a first direction in a plurality of modules of the analog multi-effector, and transmitting sound signals in a serial manner in a parallel manner in two of the plurality of modules; Characterized in that it comprises a step.

At this time, the step of transmitting the sound signal in a serial manner in a parallel manner, it is preferably performed by the relay control of the circuit board embedded in the analog multi-effector main body.

Therefore, according to the technical spirit of the present invention described above, first, by operating the reverse signal transfer operation switch by using the relay (RE) 138, the direction of processing of the acoustic signal can be made in the existing analog multi-effector. You can have a completely different versatile sound effect that never existed.

For example, if the overdrive is connected first and then the distortion is connected in series, the overdrive, which has the effect of amplifying and distorting the signal, inputs a louder volume to the distortion that distorts the input sound signal, even the smallest sound. Increased distortion effect. However, when the distortion is placed before the overdrive, there is a difference that the effect of amplifying the distorted sound of the distortion is focused, so that more various sounds can be implemented in the analog multi-effector depending on the order of modulating the acoustic signals of the guitar. It becomes possible.

In addition, as shown in FIG. 10, the parallel processing operation switch is performed through a relay (RP, 140) control in a specific module, so that the sound signal input from the guitar is separately processed by two different modules. Combined, sound effects can be achieved within the analog multi-effector completely different from the serial connection.

For example, when a chorus and tremolo are connected in series, the chorus that emits two guitar sounds recognizes the chorus as the original by passing through the tremolo that shorts the sound. In the case of parallel connection, the chorus effect of the original sound and the tremolo of the original sound are combined separately and then combined to produce a completely different sound effect from the series. Therefore, it is possible to realize more diverse and different sound signals in the analog multi-effector.

The plurality of modules 102 provided with an LED lamp 104 and an operation switch 106 for displaying an operation state and an upper surface of the analog multi-effector main body 100 are provided. It includes a plurality of channels in which the LED lamp 130 and the operation switches 128, 132, and 134, which have a function capable of operating by programming and display the operation state of the corresponding channel, are installed. The plurality of cable connection units include an input jack 136 and an output jack 150 to which an acoustic signal of an electric guitar is input, a send jack 142 connected to an external amplifier (Amp), a return jack 144, and the amplifier. In the case of using two channels, there is an amplifier channel switch jack 148, an amplifier reverb switch jack 146, and the like. In addition, a plurality of effectors may be connected to side surfaces of the analog multi-effector main body 100 through separate send jacks and return jacks as shown in FIG. 1.

The channel will be described in more detail with reference to FIG. 4, which follows the operation of a circuit board inside the analog multi-effector body 100 by the channel operation switches 128, 132, and 134.

In addition, the analog multi-effector according to the present invention is provided on the upper surface of the analog multi-effector main body 100 and can reverse the transmission of sound signals of a specific module, for example, modules 4 and 5, in the module in the opposite direction. And a LED lamp 118 for indicating an operation state of the signal transfer operation switch 116 and the reverse signal transfer operation switch 116. Here, the reverse signal transfer operation switch 116 will be described in more detail with reference to FIGS. 6 and 8.

On the other hand, the analog multi-effector according to the present invention, which is provided on the upper surface of the analog multi-effector main body 100 can convert the sound signals of a specific module, for example, module 2 and module 3 among the modules from a serial method to a parallel method. The parallel operation switch 112 and the LED lamp (114) for displaying the operating state of the parallel operation switch 112 may be included.

In addition, the analog multi-effector main body 100 according to the present invention includes a bank display unit 120 that displays a bundle state of channels on an upper surface, a program loop edit switch 122, an amplifier channel switch 124, and an amplifier reverb. The changeover switch 126 may be installed separately.

Referring to FIG. 3, the modules 102 are shown operating individually in six loops. The individual modules 102 may be various types of analog effectors capable of producing overdrive, distortion, reverb, delay, and compressor effects. More than 200 of these analog effectors have been introduced to date. Therefore, according to the user's convenience, various types of analog effectors may be connected through send and return jacks that may be mounted on the module 102 of the analog multi-effector main body 100 of FIG. 2.

In this case, the operation switch, specifically, the channels 128 represented by A to D, U, and S in the drawing, operate in a state where they are connected to each other with the modules 102 one by one. The signal 136 input from the electric guitar transmits the sound signal 136 in the first direction, which is the out direction on the left side from the right in. Here, the first direction in which the acoustic signal 136 is transmitted in the module is limited to the case where programming is not applied to the channel as shown in FIG. 4, and the first direction is changed in various forms when the programming is applied to the channel. can do.

However, when the electric guitar and the analog multi-effector are connected by using four cables (4CM: Four Cable Method), the acoustic signal 136 transmitted from the modules 6, 5, and 4 directions is a power amplifier (PWR-AMP, 220). And an amplifier 200 consisting of a pre-amp (PRE-AMP) 210 and an amplifier in jack (212) of the pre-amp (PRE-AMP), and the amplifier send jack of the pre-amp (PRE AMP). The audio signal 136 is transmitted through the module 214 in the

module

3, 2, and 1 directions and is input in the OUT direction on the left side. On the other hand, although not shown in the figure, the sound signal 136 output in the OUT direction of the left and the amplifier return jack 252 of the amplifier 200 composed of a power amplifier 220 and a pre-amplifier 210 and Can be reconnected.

Referring to FIG. 4, when the acoustic signal 136 of the electric guitar is transmitted in a first direction from in to out, and the electric guitar and the analog multi effector are connected through four cables, module 6 , The sound signals output in the 5 and 4 directions are transmitted to the

module

3, 2 and 1 directions through the amplifier in terminal 212 and the amplifier send terminal 214 of the preamplifier. In this case, the channel operation switch 128 denoted by A indicates that the module 1, the module 2, and the module 4 are simultaneously bundled and operated. In addition, the channel operation switch 128 denoted by B indicates that the module 2, the module 3, and the module 5 are bundled. In addition, the channel operation switch 128 denoted by C may be operated by combining the module 4 and the module 5, and the channel operation switch 128 denoted by D may operate connected to only the channel 4.

In addition, the channel operation switch 132 denoted by U may operate as a bank changeover switch, and the channel operation switch 134 denoted by S may operate as a loop changeover operation switch, respectively, as shown in FIG. 2. LED lamps can be installed nearby to operate. In other words, the two channel operation switches 132 and 134 are used as other functions and show an example of operating in 6 loops and 4 channels.

FIG. 5 is a conceptual diagram illustrating the addition of a parallelization function and a backward forwarding function to each module in FIG. 2 according to a preferred embodiment of the present invention.

Referring to FIG. 5, the inverse signal transmission capability (B), which is a key feature of the present invention, is applied between the module 4 and the module 5, and the parallelization function is applied between the module 2 and the module 3. Shows that Therefore, as shown in the table below, when the parallelization function (a) includes

modules

2 and 3, the channel operation switch originally indicated by B may be labeled as “B *”. In the table of the drawings, the portions indicated by “B *” in the

banks

2 and 4 indicate that the parallelization function according to the present invention is applied to the B channel. Similarly, the reverse signal transfer function may be applied to the C channel including the module 4 and the module 5. In the table of the drawings, the portions indicated by “C *” in the

banks

3 and 4 indicate that the reverse signal transmission function is applied. Therefore, according to the preferred embodiment of the present invention, when four banks are applied, there is an advantage in that a channel having a more diverse tone may not be realized.

The above-mentioned parallelization function and reverse signal transfer function are performed by control of a relay built in the circuit board of the analog multi-effector main body 100 shown in FIG.

This parallelization function and reverse signal transfer function can implement a new sound effect that cannot be realized in the existing analog multi-effector, and allows a more versatile sound to be derived from an acoustic signal of an electric guitar.

Referring to FIG. 6, modules 4 and 5 are provided with relays R4 and R5 for controlling them. However, according to an embodiment of the present invention, it is possible to transmit the sound signal 136 signal input from the electric guitar to the second direction that is opposite to the first direction transmitted from the right to the left, that is, from the left to the right. To this end, a separate relay (RE, 138) connected to the circuit board in the main body is designed in connection with the microcomputer (C, 190). In more detail, the operation principle of the relay connected to each module will be described with reference to FIG.

FIG. 7 is a block diagram illustrating an operation switch of each module being turned on and bypassed by an operation of a relay.

Referring to FIG. 7, the diagram (a) on the left shows that the module is turned on by the operation of the relay. In detail, when the input acoustic signal 136 is input, the R4 relay in the relay on state is automatically connected to the RC8 and the RC6 as shown by the dotted line therein, and the RC1 and the RC3 are automatically connected. Therefore, the input acoustic signal 136 is transferred from the RC8 contact point to the RC6 contact point so that the sound effect of the module is applied to the sound signal, and then outputted to the outside of the relay through the RC1 and RC3 contact points.

In addition, (b) of the right side shows that the module is bypassed (Bypass) operation by the operation of the relay. Specifically, when the pressure acoustic signal 136 comes in, the R4 relay in the bypass state connects the contacts of RC7 and RC6 and connects the contacts of RC2 and RC3, respectively, as shown by the dotted line in the figure. Therefore, the input acoustic signal 136 is directly transmitted from RC8 to RC2 without passing through the module, and then to RC4 outside the R4 relay.

Referring to FIG. 8, an additional relay (RE) 138 which is additionally installed together with the R4 and R5 relays for operating each module 102 described in FIG. 7 to enable the reverse signal transmission function is operated. Shows. The operation of the additional relay 138 is achieved by the microcomputer 190 performing a program input to the memory 192 inside the circuit board. Specifically, first, the input sound signal 136 is input to RE9 of the additional relays RE and 138. At this time, since the additional relays RE and 138 are on, the contacts RE7 and RE9 are connected, and RE1 and RE3 are connected to each other. Thus, the input sound signal is first sent to R48 of module 4, rather than going to module 5, which is the original direction through RE7-> RE5.

The input acoustic signal 136 transmitted to the R4 relay used to control the module 4 is applied to the sound effect of the module 4 through R48-> R46, and then added again through the R41-> R43. Return to the RE3 contact of 138). Then, at the RE1-> RE8 contact, enter the R58 of the relay R5, which operates the module 5 again, and through R56, apply the sound effect of the module 5 to the input sound signal 136, and the additional relay (Re) through R51-> R53. , 138) is passed out of modules 4 and 5 via RE6-> RE4-> RE2.

Accordingly, it can be seen that the direction of the input sound signal 136 is reversed between the two modules from the module 4 to the module 5 by the operation of the relays RE and 138 added from the module 5 to the module 4. . The operating principle of the analog multi-effector having a reverse signal transfer function according to the present invention allows the input sound signal 136 to achieve a sound effect that cannot be realized conventionally, thereby making it possible to widen and enrich the sound effect of the effector. It works.

FIG. 9 is a block diagram illustrating a parallelization function in FIG. 5.

Referring to FIG. 9, an input acoustic signal 136 transmitted from an electric guitar includes R2 and R3 relays provided for operation of

modules

2 and 3, and an additional parallelization relay RP operated by control of the microcomputer 190. It is shown that the input sound signal 136 transmitted in series by operating in conjunction with 140 is transmitted to the outside in parallel from the parallelization relays RP and 140.

Referring to FIG. 10, an input acoustic signal 136 is initially input to the R38 contact of the R3 relay in module 3. At this time, one signal is applied through R38-> R36 and then the sound effect of module 3 is output, and then R31-> R33 is passed through RP3-> RP1 of parallelizing relays (RP, 140) and R23 of R2 relay to outside. Is output.

On the other hand, the other signal in the input sound signal 136 input to R38 is transmitted to the parallelization relay (RP, 140) via a path that is bypassed (by-pass). Specifically, after applying the sound effect of module 2 through R28-> R26 of R2 relay through the contact RP6-> RP8-> RP2 of the parallelized relay (RP, 140) added at the R38 contact of R3 relay, it is output to the outside. It is output to the outside of the module 2 and the module 3 by combining the input acoustic signal 136 from the R23 to the module 3 through the contact R21 of the relay R2. That is, a parallel operation is performed in which the sound signal from the module 3 and the sound signal from the module 2 are combined into one at the R23 contact of the R2 relay.

Therefore, it can be seen that the input sound signal 136 is switched from the serial type to the parallel type by the operation of the added parallelization relays RP and 140. Therefore, the operation principle of the analog multi-effector having the parallelization function according to the present invention allows the input sound signal 136 to achieve a new sound effect that cannot be realized conventionally, so that the sound effect of the effector can be made wider and richer. There is.

The present invention is not limited to the above embodiments, and it is apparent that many modifications can be made by those skilled in the art within the technical spirit to which the present invention belongs.
