Pioneer SG-9800 Stereo Graphic Equaliser (Made in Japan from 1980-1981)
The Pioneer SG-9800 is a 2 channel, stereo, 12 element graphic equaliser with tape monitor.
The graphic equaliser divides the audio frequency spectrum into 12 segments from 16Hz to 32 kHz, with each segment corresponding to an octave.
Individual controls for each segment provide continuous adjustment (from -10dB to +10dB) and allow the sound to be contoured in order to compensate for equipment and speaker characteristics, listening room acoustics or personal preferences.
Adjustments can also be performed during recording.
