    Hallo,
    I know this has been posted before, but I need to have detailed technical information.
    I need to run two NEOS 8ch PCAOM and 3 CT6800 projectors from one QM2000... Can anybody tell me what kind of amplifier to use and the wiring needed to connect all these together??
    Thank you so much!!!

    Thanks Steve, I had already seen it...
    but I'm wondering if there is something ready to use... if not I've to build it myself but the problem is that I found at least 30 different types of OpAmps (Low power, single supply, precision, differential, fet input, high speed, video Op... etc) with different voltage, current and frequency...
    Is there a type that someone can raccomand me for this precise application?
    Thanks again!

    Hi

    For distances up to 50m I never had problems with Y cables. Without amplifiers! Just 1 cable splitted onto 2 cables.
    So, try splitting all used QM signal wires (or better all 25 wires) to 3 x 25 wires. Every 1 wire to 3 wires. It should work. But be aware of possible ground loops! Use only one power-distribution socket for all equipment (near computer).

    Good luck!

    we have used TL07x (TL071, TL 072, TL074) opamps in similar applications with no issue.
