A simple but effective 3 band equaliser for the 500 Series system, the 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.
As with the other 500 Series modules on this range, the signal path is True Class A with a Lundahl output transformer. The Tonic has a big grunty sound with stacks of headroom making it an excellent tracking equaliser and a perfect partner to our Elixir mic preamp. Add an Essence compressor and you have a complete Buzz Audio channel strip!
