OVERVIEW

This is a Class A, 4 band Equalisers which is in an 8 3/4 inch size module case. It has a single sensitivity switch which is used for Mic and Line input sensitivity adjustment, and Dual concentric controls for frequency select and Boost/cut.

It has shelving curves only on the HF and LF sections.

It uses a single PCB construction and has Transformer balanced Input and Outputs.

Generally this module is purchased by Clients who want a really good, clean Mic pre and the equaliser section is to them of secondary importance. Used largely for Drums and bass by these clients.

Fitted with 18 way Amphenol connector.
