Hi, can you give me the model number on the back of the amp? If those where not part of a unified kit and assembled over time i would also need the model number of all other component of the system.
Hi. That equalizer seem to support one item at a time. in the manual example at page 4 they show the connection to put the equalizer between the amp and the tape deck connected to tape 1:
To allow also the CD player and the phono to use the equalizer would require an RCA jack switch to select between them.
The turn table connect with a stereo RCA cable to the amp phono input and the third wire need to connect to the ground connection on the back just next to the phono input.
The CD player also require only 1 stereo RCA cable to the amp input labeled "CD". Tuner should also only have a stereo RCA cable between it and the amp input called "Tuner".
Try to hook and test one at a time, adding one new at each succesful test.
