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. SPECIFICATIONS INPUTS Sensitivity Range Single sensitivity switch selects either microphone input from -80dBm to -20dBm in steps of 5dB or line input from -20dBm to dBm in steps of 5dB Input Impedance (transformer balanced) Mic: 1200ohm Line: 10kohm OUTPUTS Output Impedance (at 1kHz) (Transformer balanced)<75ohm Maximum Output >? into 600ohm EQUALISER HF controls 4 switched frequencies: 4K, 8K, 10K, 15K.

It has a Dual concentric sensitivity switch which has a stepped Mic sensitivity on the outer with a Line trim potentiometer in the center. Mic and Line is selected by a toggle switch or it can be remotely selected. It is available with either the Class A/B output stage or with the option of Mr. Rupert Neve's Class A output stage and special output transformer. This version is called the SR12. The Class A/B version is usually purchased for the versatility and transparent sound of its Equaliser section. The Version which has Rupert Neve's Class A output stage has the best of both Worlds, but of course is slightly more expensive. Can be supplied fitted with 22 way Amphenol connector (with pre and Post Eq ) or with 18 way Amphenol so that it can be retrofit into Neve Consoles which had 1081 or 1064 Equalisers. SPECIFICATIONS INPUTS Sensitivity Range Outer dual concentric switch selects microphone input from -70dBm to -15dBm in steps of 5dB. Inner control selects line input continuously variable from -10dBM to ? (-20dB to ? as option) Input Impedance (transformer balanced) Mic: 1200ohm Line: 10kohm (transformer balanced).
