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.
- 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 +10dBM (-20dB to +10dB as option)
