Buzz Audio Tonic
A simple but effective 3 band equalizer for the 500 Series system, the Buzz Audio Tonic utilizes real inductors (chokes) in the high and low bands. These two bands are switchable shelf or bell modes and have 2 turn over frequency choices. The sweepable mid band features the Constant Amplitude Phase Shift circuit proposed my Mr Steve Dove in 1981 which has a very fluid sound. A high pass filter is also provided with two frequency choices (50Hz or 80Hz) selected by the user with jumpers on the pcb.
