Problem with Carver/SR7001

I'm sure this is a dumb question, but I am new to all this so have mercy..

I'm just trying to set up a 2.1 system with:

Polk SRS 2.3TL
SVS PB-10
Marantz SR7001
Carver m-1.5t

When I connect the amp to the preouts on the 7001 using RCA's I get pass through but no amplification. However, if I run RCA-speaker wire directly from the amp to the L/R Binding posts it is fully operational. What could be the problem? Bad preout? The 7001 I just picked up recently, it is refurbished.

    You should only get amplification if you have speaker wire connected to the loudspeakers....not with RCA only.

    Marantz - Pre-Out Front L&R - Carver 1.5t - Input L&R - Output L&R Binding Posts - SDA
    CTC BBQ Amplifier, Sonic Frontiers Line3 Pre-Amplifier and Wadia 581 SACD player. Speakers? Always changing but for now, Mission Argonauts I picked up for $50 bucks, mint.

    I should have clarified...

    Marantz - Pre-Out Front L&R - Carver 1.5t - Input L&R - Output L&R Binding Posts - SDA
    -With this connection I just get pass through, no amplification

    Marantz - L/R main binding posts - Carver 1.5t - Input L&R - Output L&R Binding Posts - SDA
    -With this connection amplifier works, but I get a constant hum in the right channel. The connection between the receiver binding posts and the amp is rca on one side (amp) and speaker wire on the other side (marantz)

    Why are you connecting the speaker level outputs from the Marantz to the Carver? You shouldn't do that.

    What does "pass through only" mean? The pre-outs do exactly that, simply pass the signal on to the next component.

    I just get very low level output...should I be getting into the +db volume range when connected to the amp?

    That will vary with any amplifier you connect do to the different gain characteristics between both components. Keep turning it until you get volume without distortion, which should be fairly easy to determine.

    I'm not positive about that amplifier, but doesn't it have adjustable gain for each channel? If so, turn them all the way up.

    It doesn't have gain controls, but I have it figured out now. Thanks!
