The TEAC EQA-10 is a stereo graphic equaliser with a total of 10 adjustable bands for each of the left and right channels. It contains three separate input channels and switchable modes for live and tape monitoring purposes. The LED display shows the performance of the unit across all the frequency bands, and clipping indicators above each of the gain sliders indicate if there are any overloaded channels.

Ensure the amplifier and the EQA-10 are both powered off. Turn the gain and master volume on the amplifier to zero. Set all the EQ sliders on the EQA-10 to the central "zero line."
Check the rear of the amplifier panel for the types of connections available. For home audio use, the "Preamp" sockets are preferable. Connecting the EQA-10 using these sockets will apply the EQ effects to all other devices connected to your amplifier, without interrupting the signal chain. Connect the "Preamp Out" sockets to the "Input" jacks on the rear of the EQA-10. Connect the "Output" jacks on the EQA-10 to the "Preamp In" jacks on the rear of the amplifier.
Power on the amplifier, and switch on the EQA-10 by pressing the "Power" button on the left side of the front panel. Use the amplifier as normal and adjust the sliders on the EQA-10 to create the desired tone-shaping effects for your music.
Use tape monitor mode if your amplifier does not have a set of Preamp connections. Connect the "Line In" inputs on the rear of the EQA-10 to the "Tape Deck" outputs on the rear of the amplifier. Connect the "Tape Deck" inputs from the amplifier to the EQA-10 "Line Out" sockets.
Switch on the "Tape Monitor" mode on the amplifier. Switch the "Tape" switch on the right hand side of the EQA-10 panel to "On."
Play some music through the amplifier to ensure all the connections are correct. Not all manufacturers use the same conventions for "Input" and "Output." Some of them use the opposite definition, meaning the connections will all need to be reversed to obtain the proper signal path. If you can see the LED display on the front of the EQA-10 moving, the unit is receiving a proper input source.
