Dear all,

I extend Keeley's Parallel Mixer design by adding one loop with phase inverter. So SW1 & SW2 are the phase inverter switch and switches after returns are mute switch. All coupling caps are 1 uf as I have bunch of WIMA's 1 uf, so why dont use it ?

The dual supply power will come from separate board using NE555 which converts +9V into +/- 9V.

Keeley Parallel Mixer is here : http://www.robertkeeley.com/manuals/Kee ... _Mixer.pdf

Could you please kindly check the attached schematic ? Thanks in advance
