Hello all, I have just set up an amp with a tape deck, the problem is i have to use the rec out port on the back of the amp to be able to listen to anything. I tried connecting the tape deck aswell as my pc. The rec out port seems to be the only port to work, if I use the other ports for aux, tuner, and CD, there is very faint music if I turn the amp up to max. There doesn't appear to be a monitor button on the amp which would be an obvious answer, the model is technics SU-X101. Thanks for any help, or just a read. Ben.
