Audio equalisers can adjust the tonal qualities of music by boosting or decreasing different frequencies from the signal for shaping the overall sound. Two standard pairs of stereo cables connect the equaliser to a receiver or amplifier, which is hooked up to other stereo components such as a tape deck and CD player. The stereo cables are colour-coded to distinguish the left audio channel from the right. By matching the stereo plugs to the colours on the jacks, you can connect an equaliser in minutes. Use additional stereo cable to connect the tape deck and CD player.
Connect one set of stereo cables to the left and right output jacks on the rear of the equaliser, then hook up the other ends to the Tape 2 Monitor Playback input jacks on the back of the amp or receiver. Match the white plug to the left jack and the red plug to the right jack. Jacks are typically colour-coded to match the plugs.
Insert the plugs on a second set of stereo cables into the input jacks on the equaliser and connect the other ends to the Tape 2 Monitor REC (record) jacks on the amp or receiver.
Connect a third set of stereo cables from the input (record) jacks on the tape deck to the output jacks for Tape 1 on the back of the amp or receiver. Connect the fourth set of stereo cables from the tape deck's output (playback) jacks to the Tape 1 input jacks on the amp or receiver.
Connect the last set of stereo cables from the white and red audio output jacks on the rear of the CD player to the jacks labelled for a CD player on the back of the amp or receiver.
Press the Tape Monitor button on the front of the amp or receiver to activate the equaliser for use with the other components you connected to the amp or receiver.
Unplug the components from the electrical sockets while you're hooking up audio cables. This will prevent a possible short-circuit.
