OUTPUT A (MONO)/ OUTPUT B Jack The output jacks are used to connect the unit to an amplifier or another effects unit. * For monaural output, use Output jack A. * For stereo use: Output A: Only the processed signal (pitch modulated sound) is output. The CEB-3 adopts the "space synthesis system" for stereo output. That is, the depth of the effect varies depending on the distance between speakers. Note that lowering a filter control knob or effect level too much will shift the sound image to the Output B position, and therefore diminish the effect.
