Control Elements
IN 1 and IN 2 Switch
With IN 1 and IN 2 you select the source to listen to on speakers and
headphones. Like all switches they illuminate after activation so that
you can easily see which source is selected. Activation of both switch-
es sums the input signals.
Mono
The MONO switch creates a sum of the left and right channel, so you
can listen to stereo sources also in mono on speakers and headphones.
You can also listen to a mono source on both monitoring channels.
The MONO switch is of course also important and useful to examine
the mono compatibility of a mix. Phase alterations or reversions that
may not be too obvious in the stereo panorama can be detected more
clearly in a mono sum – in extreme cases they lead to cancellations.
Dim
The DIM function reduces the listening level (Volume) by around 15 dB.
Normally you employ this function when mixing to choose between two
defined volumes to avoid having to move the VOLUME control.
Volume Control (Speakers)
The VOLUME level control allows you to increase or decrease the signal
level of both channels for all speaker outputs (SP 1, SP 2 and SP 3). The
VOLUME control is calibrated in a relative dB scale that refer-
ences the input level. At the 0 dB position the input signal is
led to the output with an unaltered level (unity gain).
The VOLUME potentiometer covers a control range
from -80 dB to +7 dB. Thanks to the signal amplifica-
tion you can listen louder to quiet passages and in
general better check the material if you are hearing
for acoustical problems (artifacts, noise etc.).
Calibrate the whole monitoring system (refer to
page 17) so that the effectively used control range is
always somewhere between the 8 and 4 o’clock po-
sitions. In this case, the potentiometer is working op-
timally and you insure a well-aligned, low-noise gaining
for the whole monitoring chain. >
