User manual PIONEER GR-333

[. . . ] If the voltage is not properly set or if you move to an area where the voltage requirements differ, adjust the selector switch as follows. Insert the screwdriver into the groove on the voltage selector, and adjust so that the tip of the arrow points to the voltage value of your area. These are to be used to connect the graphic equalizer to your stereo amplifier. [. . . ] 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.

When the EQUALIZER button has been set to ON, these controls may be adjusted. When a control is raised upwards from the "0" position, the frequency band corresponding to that control will be emphasized; when the controls is lowered, the frequency band will be attenuated. When this switch is set to the ON position, power is supplied to the unit's main circuits (Equalizer indicators lights). Even when performing playback without using the functions of this component, be sure that its STANDBY/ ON switch is ON. Play the music and try operating each of the controls to produce the best effect. By moving the controls up or down, the volume of the instruments preferred can be boosted or other instruments can be attenuated. for instance , it is possible to boost the 60 Hz frequency and give the bass drum a greater "punch" or boost the 1 kHz frequency and position the vocals at the front. When the 6 kHz frequency is boosted, the cymbals and "high hat" sound much clearer. 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. [. . . ] 4 kHz controls are raised and the other controls lowered, people's voices sound as if heard on a telephone. Noise can be reduced during recording and playback When the high-range controls are boosted in step fashion during recording and then lowered in reverse fashion during playback, tape hiss and other high-range noise can be reduced. Preventing howl during mixing play Any irritating howl during play can be prevented by lowering the knob corresponding to the frequency band in which the howl occurs. [. . . ]
