The exact process for hooking up an equalizer to a receiver depends on the connections available on the receiver. In general, the equalizer needs to process the sound before it gets amplified. If the receiver does not have the necessary connections to allow this, the equalizer can be connected between the source (such as a CD player) and the receiver.
Items you will need
- Two sets of stereo audio patch cords
- Four audio adapters: 1/4 plug-to-RCA style jack
Connecting the EqualizerStep 1
Attach two audio adapters to one end of each audio patch cord.
Check the receiver for a Tape Monitor switch on the front panel. If there is one, locate the Tape Out / Tape In jacks on the rear of the receiver. They may also be called Rec Out / Mon In. If there is no Tape Monitor switch, refer to Tips.
Connect a patch cord from the Tape Out jacks of the receiver to the Input jacks of the equalizer.
Connect a patch cord from the Tape In jacks of the receiver to the Output jacks of the equalizer.
Hookup is complete. Use the Tape Monitor button to add equalization to any audio source played through the receiver.
- If the receiver does not have a Tape Monitor switch, the equalizer must be connected between the audio source and the receiver. For example, if the source is a CD player, connect the CD player to the Input jacks of the equalizer, and connect the Output jacks of the equalizer to the CD Input of the Receiver.
- Some receivers may have a set of jacks labelled Pre Out - Main In. These are usually connected to each other with jumpers. The jumpers can be removed and an equalizer connected here, but there may be distortion at higher volumes. A receiver with these jacks will almost certainly have a Tape Monitor switch, and that is the preferred connection.
- Older equalizers may have RCA-style plugs, and in that case audio adapters are not required.
- Ensure all volume controls are at the lowest level before turning the power on. After turning the power on, wait a minute, then turn the volume up slowly. A low-pitch hum indicates a loose connection or faulty patch cord. At high volumes this hum can damage speakers. Turn off the power and check that all connections are tight. If the problem persists, replace the audio cables.
