Changing Gain of Sonic Impact Gen 2 unit

[ttan98]

Anyone can direct me to the circuit diagram where I can change the gain of this unit. Incl the components to change.

I am current using it as a unit in a biamp configuration. Rather than having 2 volume control knobs I want to use just a single 4 gang vol. knob for 2 amplifiers.

Thks.

I would try a passive attenuator. . .many different types but
effective.

I use passive in front of the power amp, I need to change the gain of both power amp equal, one of them is sonic amp.

I don't know, but you could probably deduce it from the chip datasheet + looking closely at the PCB.

Sure can.

online ta2024 gain calculator

This is my online calculator for working out the gain of a TA2024 chip. Basicly you adjust the feedback and line level resistors to achieve the gain that you are looking for.,

Hope it helps....
