Buzz Audio Tonic 500 Series

Before modern semiconductor technology, audio filters and equalizers were made with passive components - capacitors and wound coils of wire that formed inductors (or chokes).  Audio frequency chokes were bulky and expensive so these days it's easier (and cheaper) to use an electronic circuit to simulate the inductors. However, we have discovered that the difference in sound between the real thing and a simulator is quite noticable.  So with the tonic equalizer we have brought you the best of both worlds, utilizing both real chokes and electronic filters in perfect harmony.The Buzz Audio Tonic offers three bands of equalisation with a versatile sweep midrange section and fixed two frequency high and low bands.  The tonic also has a high pass filter utilizing another real choke.  The signal path of the tonic is all True Class A discrete transistor with the output balanced via a Lundahl LL1517 high spec transformer. The tonic is designed to fit into the popular API 500 Series modular rack
