    I recently came into possession of an NAD C370 amplifier along with a pair of ProAc Tablette 2000 bookcase speakers, an audioengine s8 subwoofer, and a music hall usb-1 turntable. I used to use the turntable and the sub with a pair of powered audioengine a5's and that worked out great, but I just got all this nice gear and tried to hook it all up.

    It didn't go great.

    As of right now have the sub hooked up to the pre-out 1 output and the turntable hooked up to the Tuner input (there isn't a phono). The speakers are hooked up to the A outputs, but when I play the turntable I can only hear the subwoofer, which can be adjusted with the main volume knob.
    Before this I tried running the turntable into the Main In inputs but when I played it that way it was unbearably loud and the volume knob did nothing. I have to assume that the Main In input is for an input with its own adjustable amp, but I do not know how to make any of the other inputs come through the speakers.

    Any knowledge, experience, or wisdom would be much appreciated.
    Thank you.

    Make sure that the Phono/Line switch on the TT is set to Line. That engages it's own pre-amp.

    There should be links in place between Pre-out 2 & Main in. Sounds like they may be missing.

    For future reference, this section is for AV. Stereo belongs here. ;)

    Turntable - ignore the USB Output and use the 2RCA Line Output. The NAD amp lacks a dedicated Phono Input so you need to set the Turntable Output to use its internal Phono Pre-amp.

    Subwoofer - with no dedicated Sub out on the NAD Amp you will use the LR Pre Out to connect to the LR Input on the Sub and use the Sub crossover and Level controls to blend the Sub with your LR Speakers.

    Loudspeakers - check your wiring. It looks like the Speakers can be 'Bi-wired' check you have links in place between the LF and HF connectors. Use a 9V battery to test that the speaker drivers are functioning.

    Thanks guys. I guess the linkages went missing at some point before this came into my possession. I just threw some spare RCA cables in there and everything is working great now.
