Definitions

  • the invention relates to an amplifier for musical instruments, in particular a guitar amplifier, with at least one channel and at least one electronic memory for set parameter values such as delay, reverb, chorus, flanger, tremolo, treble, mids, bass, channel volume, overall volume and the same.
  • amplifiers for musical instruments in particular for electric guitars, have at least two channels, each with different gain characteristics, for producing amplified signals with different tone colors.
  • a musician selects one of the channels, often also switching between the channels when playing a single piece of music.
  • analog amplifiers are still frequently used in which the sound itself is generated conventionally via a tube or transistors.
  • such analog amplifiers may also have a digital signal processor used to generate additional sound effects such as reverb, reverb, flanger, tremolo, and the like.
  • analog guitar amplifiers with integrated digital signal processors are already on the market for generating sound effects that have an electronic memory for storing such set parameter values.
  • the set parameter values can be stored in the electronic memory by triggering a memory operation manually, for example by pressing a corresponding key. For example, a musician can set and save the desired parameter values for each channel during a rehearsal.
  • the musician wants to change the settings while playing, for example to adapt the sound to a particular piece of music, or because there are different acoustic conditions than, for example, a previous sample. In this case, it will thus change the parameter values during the game and thus mostly under time pressure.
  • the user In the case of the conventional amplifiers, the user must first first initiate a memory operation before changing the channel in order to store the newly set parameter values of the first channel if, when the channel is changed again, the same parameter values are again found for the first channel want.
  • the manual triggering of the storage process requires time and additional concentration and is easily forgotten.
  • This object is achieved according to the invention in that means are provided by which the storage of the parameter values of at least one channel, preferably of all channels, can be carried out automatically. This ensures that set parameter values are not unintentionally lost, but are available again when the device is switched on again or when it returns to the respective channel.
  • the additional step of manually triggering a Speicher ⁇ process deleted, making the operation for the musician is much easier.
  • the amplifier according to the invention therefore behaves in a manner of speaking like a classical amplifier with potentiometers or similar means, in which the set values are retained solely by the switching position or the switch state.
  • the means may be designed such that storage takes place when the channel is changed. In this way, data loss when switching from one channel to another channel is avoided.
  • the means may be designed such that storage takes place when the power supply is interrupted. This prevents the previously set parameter values from being lost when the amplifier is switched off or during a power failure.
  • the means are preferably designed in such a way that storage always takes place in the event of an imminent loss of the parameter values.
  • an automatic storage is always carried out after setting the pertinent parameter value.
  • parameter values are not set at any time but are not stored, so that no settings can be lost even in the event of a sudden power failure.
  • At least one parameter setting controller is provided, which is assigned to two or more channels simultaneously and is effective for the particular selected channel. This reduces the total number of controls, which increases the user-friendliness and clarity. The musician, who is usually under pressure to change a parameter value during the game, quickly finds the right controller, and a mistake is far less likely than with separate controls for each channel.
  • each channel-associated controller is provided for setting at least one further parameter value.
  • These regulators may be, for example, classical potentiometers for adjusting the volume, the gain and / or the sound, in particular the regulation of the selective amplification of treble, middle and bass.
  • an individual volume control and one or more tone controls may be provided for each channel.
  • the corresponding the parameter values are then not stored electronically, but they are simply retained by the switch position of the controller.
  • the means for the automatic storage of parameter values can accordingly only be used for the parameter values which concern additional sound effects.
  • a control element is provided in each case, for example a rotatable regulator. By actuating this control element, the setting of the respective parameter value for the currently active channel is changed in each case. When a channel is changed, this setting is automatically stored and an actuation of the same operating element now has an effect on the newly set active channel.
  • At least one clean channel and at least one overdrive channel are provided.
  • common tone controls may be provided for a plurality of overdrive channels to which a corresponding number of different equalizer circuits automatically switched over with the overdrive channels are assigned.
  • FIGURE shows a frontal view of the upper part of a combined with a loudspeaker invention amplifier, a so-called combo.
  • the housing 5 of the illustrated combo having an amplifier according to the invention has a loudspeaker area 24 on its front side and an operating panel 15 above the loudspeaker area. It is a guitar amplifier to which an electrical guitar can be connected to an input socket 25 ,
  • the input signal is first amplified by a preamplifier - so-called gain.
  • an equalizer can be used to raise or lower individual frequency ranges, namely treble, mids or bass, and the signal can be processed by a digital signal processor that can produce various sound effects.
  • An analogue power amplifier amplifies the signal obtained in this way and transfers it to the built-in speaker and possibly to additional external speakers.
  • the actual amplification is generated analogously in a known manner. Whether it is a tube amplifier or a transistor amplifier is irrelevant to the invention, and therefore the amplification itself will not be discussed in detail below.
  • buttons 10, 12, 14, 16 are attached to the control panel 15 at the top left, which are assigned to four different Grund ⁇ sound channels of the amplifier, namely a clean channel and three overdrive channels “crunch “,” Lead “and” Warp ".
  • the channels each have different tone colors, in particular distortions, which are generated, inter alia, by overdriving the pre-amplifier and / or the output stage.
  • a control unit switches to the corresponding settings depending on which channel is selected.
  • An unillustrated footswitch can be connected to the repeater and allows the channel to be selected by depressing a footswitch, with each of the pushbuttons 10, 12, 14, 16 being associated with a footswitch.
  • the buttons 10, 12, 14, 16 each have a light emitting diode 17, which indicates whether the respective channel is currently active - diode lights - or not, which is particularly helpful when connected footswitch.
  • buttons 10, 12, 14, 16 for selecting the channel are four rotatable effect controllers 2, 4, 6, 8 which serve to set parameter values which serve as input values for the digital signal processor.

  • the two middle controls 4, 6 are used to set an echo effect - so-called delay -, with one controller 4, the delay time and the second controller 6, the volume of the delayed signal can be adjusted in relation to the original signal.
  • the right knob 8 is used to set a reverb effect, so-called reverb. If one of these regulators 2, 4, 6, 8 is actuated, the respective parameter value for the respective active channel is changed with immediate effect.

  • a non-volatile memory for example an EEPROM memory.
  • the storage process takes place within a period of a few 100 ms, during which the parameter values are still maintained by a suitable follow-up circuit in order to avoid data loss.
  • the effects are generated by the digital signal processor, which in turn is controlled by the control unit, respectively the current setting of the controllers 2, 4, 6, 8, or after a channel change or after switching on the device, the parameter values stored to the respective channel queries.
  • controllers 20 which serve to set further parameter values for the individual channels, wherein the control does not take place via the digital signal processor but analogously.
  • an individual volume control in the form of a potentiometer is provided, and for each of the three overdrive channels one gain control and three common tone controls - treble, mids, bass. Via equalizer circuits automatically switched with the channel, the appropriate sound is created for each overdrive channel. For the clean channel, however, separate sound controls are provided.
  • the guitarist may alter the intensity, volume, and / or tone - treble / mids / bass - of that channel with the aid of one of the knobs 20.

If it later changes back to this channel, the values are automatically recalled by the control unit and given to the digital signal processor as input values. Likewise, the set values are stored when switching off or a power failure. However, a storage can also always take place when a parameter value is reset. In this case, can be dispensed with a tracking circuit.
