Manual Control.
There are two positions for the presets, primary and trim. The primary
position (lower) allows you Trim control of the threshold, with no
control over the ratio, attack and release times. The “Trim” position
(Upper) allows complete control over the threshold and trim over the
ratio, attack and release. Manual control leaves the audio characteristics
at your complete mercy.
Output level
A trim is provided for output gain make-up that has a range of a few
dB of loss to +20 dB of gain, to compensate for whatever attenuation is
provided by the gain cell.
Summary
The operation is a little different from other limiters that you have
used. This unit provides for no gain in the gain control cell. There is
no provision for gain change as in most compressors, and this unit only
provides for program controlled attenuation of the signal path. As such,
when you increase the ratio, the attenuation increases and the signal
level decreases. This is to be made up manually. You have to play with
the controls to get where you want to go, but after walking around the
solo a couple of times with the unit, you should find it to respond as
you now expect it to.
Installation Considerations
•
Shields and signal grounding
In the best of all possible
worlds, you plug in the
input, output and power and
everything sounds GREAT,
no problems, and everything
is right with the world. Such
is not usually the case when
interfacing large quantities of
equipment in a cogent mess
such as a recording studio
control room.
