Patent ID: 8134897

Claim:
A current gain control system for independently altering gains associated with first and second input channels, comprising: first and second gain blocks respectively associated with the first and second input channels, wherein the first and second gain blocks transmit first and second gain signals in response to receiving first and second input signals; first and second converters adapted to be respectively coupled to the first and second gain blocks, the first and second converters operative for setting gains associated with the first and second input channel and for transmitting first and second converted signals in response to receiving the first and second gain signals; and first and second switches for selectively coupling the first and second converters to first and second channel drivers, respectively, wherein the first and second channel drivers transmit channel gain signals in response to receiving the first converted signal, and the channel gain signal allows control of the gain associated with the input channel, and controlling the gain for each channel enables varying power levels associated with each channel.
