4.C.3.2 Gain
The default setting for all the preamps is 0dB. The analog gain range extends from -27 to +63dB, in
1.5dB steps. To adjust an input signal correctly, select the channel to which the preamp is assigned,
then turn the gain pot in the Input section of the Channel Control panel. The new value will be visible
on the screen, as shown beneath the “virtual” pot.
The keyboard commands are [F5] to decrease, [F6] to increase the gain. On
the left of the Sensoft screen, two meters show the signal level of the selected
preamp. The left bar is a Peak meter, the one on the right is a VU level meter.
These two meters are always pre-processing, thus they represent the signal
measured at the output of the preamp. It's the same for the Sensoft Peak
meters, just above the on-screen representation of the faders. These meters
should be observed when you adjust the gain of a preamp, whether it be local
or distant. The gain should be adjusted to achieve maximum modulation on the
VU meter scale, without lingering at the 0dBFS point on the Peak meter scale.
It is foolish to assume that, in digital technology, one can “under-modulate” without a problem, given
the low background noise generated by the system. Don’t forget that the preamp is analog and that,
although it is of very high quality and very close to the source, it is still very important to optimize the
signal-to-noise ratio at the input stage.
The control of gain by [F5] and [F6] is also available on the DIRECT I/O PATCH window,
to allow the control of inputs used to transfer signals from one audio rack to another,
without these signals being assigned to one of the console faders (thus not benefiting
from the console’s channel controls).
4.C.4 Delay
For consoles equipped with the Sy80 DSP module, every input assigned to a
console channel has its own adjustable delay of 0 to 111ms. Use the
console’s
DELAY ON button to activate or deactivate the delay.
A window consisting of three fields indicates the delay in samples (smp),
milliseconds (ms) and meters (m). All you need to do is point, using the
trackball, at one of these fields and to use the left button (-) and the right
button (+) to adjust the value. According to the chosen field, this will result
in a more or less fine adjustment. The samples field allows very precise
adjustment; the meters setting gives a coarser adjustment.
