Abstract
The utility model discloses a kind of cinemas multichannel unequal power combination type power amplifier, it is characterized in that, including input interface, input control module, unequal power amplification module, output interface and power module, unequal power amplification module includes small-power amplification module and high-power amplification module, to the L of film, C, R, Ls, 5 sound channel signals such as Rs then send into small-power amplification module with relative SW sound channels want small power be amplified respectively and each channel power configuration it is identical, high-power amplification module is then sent into film SW sound channel signals and is amplified in high-power mode, one sound reproduction of movie theater can be completed with a multichannel unequal power combination type power amplifier by the utility model, function admirable low cost has more preferable competitiveness.
Description
Technical field
The present invention relates to a kind of sound equipment, more particularly to a kind of movie theatre special power amplifier.
Background technology
Currently known cinemas movie theater power amplifier is divided into two kinds, and one kind is stereo power amplifier, another
It is constant power multichannel combination type power amplifier, this known technology has following imperfection part：1. every stereo work(
Rate amplifier only has two passages, realizes that reproduction systems more than 6 sound channels of movie theater needs many power amplifiers could to complete, not only into
This is higher and takes up room larger, is not suitable for small-sized movie theater and uses.2. constant power multichannel combination type power amplifier generally by
The equal passage composition of 4 power, due to the limitation of number of channels and power, it both can not put to L, C, R, Ls, Rs sound channel
SW sound channels are amplified again during Datong District, because in movie playback, secondary bass SW sound channels will consume 60-80% in movie playback
Power, therefore the constant power multichannel combination type power amplifier of suitable playback L, C, R, Ls, Rs sound channel is too small per channel power,
It is not enough to promote SW sound channels, and promotes other sound channels to produce huge waste by the power demand configuration power of SW sound channels,
Energy consumption cost is all uneconomical.
The content of the invention
It is above-mentioned to solve it is an object of the invention to provide a kind of cinemas multichannel unequal power combination type power amplifier
At least one of problem is whole.
According to an aspect of the invention, there is provided a kind of cinemas multichannel unequal power combination type power amplifier,
Including input interface, input control module, unequal power amplification module, output interface and power module, input interface receives outer
Portion's audio signal is simultaneously sent to input control module, and the audio signal that input control module reception input interface sends simultaneously is carried out
Unequal power amplification module is sent to after control, unequal power amplification module receives the audio signal that input control module sends
And carry out being sent to output interface after unequal power amplification for different sound channels, output interface 4 receives unequal power and amplifies mould
Audio signal that block sends simultaneously is sent to external equipment, and power circuit provides power supply for above-mentioned each module.
According to an aspect of the present invention, unequal power amplification module includes small-power amplification module and high-power amplification mould
5 sound channel signals such as L, C, R, Ls, Rs of film are then sent into small-power amplification module and want small power with relative SW sound channels by block
It is amplified respectively and the configuration of each channel power is identical, high-power amplification module 32 is then sent into and with big to film SW sound channel signals
Power mode is amplified.
According to an aspect of the present invention, power module includes P1 power supplys and P2 power supplys, wherein, P1 power supplys are put for small-power
Big module for power supply, P2 power supplys are powered for high-power amplification module.

Block 31 is powered, and P2 power supplys 52 are powered for high-power amplification module 32, and according to an aspect of the present invention, the voltage of P1 power supplys is usual
Less than the supply voltage of P2 power supplys, the two is equal or even to merge into a power supply be a special case of the invention.
Above-described is only some embodiments of the present invention.For the person of ordinary skill of the art, not
On the premise of departing from the invention design, various modifications and improvements can be made, these belong to protection model of the invention
Enclose.
