How to install a graphic equalizer
Many audio enthusiasts enjoy having a graphic equaliser as part of their stereo system. A graphic equaliser, with it's ability to boost or attenuate specific frequency ranges, allows them to tailor the output of their amplifier or receiver to match the particular acoustics of their room.
Installing a graphic equaliser into your stereo system is a pretty straightforward task.
Examine your receiver. Graphic equalisers are connected through the "tape monitor" or "tape loop" of the receiver. If your receiver does not have this option, you cannot use a graphic equaliser with it. To be sure, check your receiver for a "tape monitor" button or switch.
Connect a set of RCA patch cords (see Resources below) to the "tape out" jacks of the receiver. Connect the other end of the patch cords to the "audio in" jacks of the tape monitor.
Connect the second set of RCA patch cords to the "tape in" jacks of the receiver. Connect the other end of the patch cords to the "audio out" jacks of the tape monitor.
Plug the equaliser's power cable into a 120-volt outlet, then turn the power for the equaliser and receiver on.
Turn on the "tape monitor" switch on your receiver, and adjust the graphic equaliser to your liking.
