Default Remote controlled Preamp for PW120 module

Hi, I'm new in this site, even if I'm a regular reader and always appreciated Diy audio advice..
So, hello to everybody.. first of all
Recently I bought a pair of solid state mosfet power audio modules PW120 (High End Audio Modules ) coupled with an external self made 700 VA power supply. The project is simple and it sounds preatty good but I would like to implement a good remote controlled preamp PGA2311 based volume control equipped with a display. The power module have about 800mV input sensitivity..
I saw this one on eBay
NEW DIY LCD PGA2311 Volume Remote Control KIT Free Knob su eBay.it Amplifiers, Home Audio, Electronics

looks well done.. but it has only 3 inputs, and I need at least 4 ! and more.. I need to command by remote also the ON/Standby function so I need one more output (rel่ or at least an open collector output) to this function...
Does anyone know something like that or have any experience with this kind of circuits, schematics ?
Thanks a lot..
