OVERVIEW

This is a more sophisticated equaliser in a 12 inch high module case with Hi Q on the two mids, and has peaking and shelving curves selectable on both the HF and LF bands.

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
