
Input odd is routed to the Left bus, input pair is routed to the
Right bus

The even input is routed on the mix down Left and the odd on
the mix down right. But, Over writing these routing remains
possible!
In “M/S” mode
the transducers often have different sensitivity:

The input gain adjustment is kept separate for channels odd and
even,

The odd channel control adjust the couple level

The event channel control adjusts the stereo image width. In the
center detent position, a coherent couple should provide a
normalized 110° angle

Whenever inverting the phase of channel even, after decoding
from M/S to L/R the stereo image is reserved L

R

Manual routing is inhibited and the signals are routed and
decoded as follows:
Input impair is the “M” signal, input pair is the “S” signal;
Input Input pair (M+S) is routed to the Left bus;
Input impair - Input pair (M-S) is routed to the Right bus.
Limiters
A limiter can be inserted into each channel, after the channel fader. This is a
fast limiter with a dynamic range wide enough to stand the 40 dB overhead of
the input stage. The activation of the limiter is shown by an LED.
As long as the signal level stays below the limiter threshold, little effect is seen
on the signal. When the limiter is triggered, its output stays 6dBFS below the
A/D converter clipping level for up to 40dB input overdrive.
It can thus be seen as a “safety” limiter, that may be left active all the time!
The threshold can be adjusted through the menu from –12dBFS to –3dBFS
