[. . . ] The white plug is for the left channel, and the red plug is for the right channel. If your stereo amplifier has only one set of TAPE/ADAPTOR or TAPE MONITOR jacks, connect them to the graphic equalizer's INPUT and OUTPUT terminals. When stereo amplifier has two sets of tape/adaptor jacks: Connect [INPUT] jacks to the stereo amplifier's TAPE2/ ADAPTOR [REC] or TAPE2 MONITOR [REC] jacks, and connect [OUTPUT] jacks to the stereo amplifier's TAPE2/ ADAPTOR [PLAY] or TAPE2 MONITOR [PLAY] jacks.

Instruments and vocals have a great many harmonic components along with the fundamental frequency band and so you can have lots of fun operating 7 controls to achieve the sound of your choice. In order to protect the speakers from damage resulting from power overload, do not excessively increase the stereo amplifier's volume level when boosting the treble range on this unit. The sound of vocals and instruments can be colored at will by operating the controls. 4 kHz controls are raised and the other controls lowered, people's voices sound as if heard on a telephone.
