FIXED Gain mode
In some systems (some A/V installations, for example) it is desirable to set a particular input to a
fixed gain, that is then becomes unaffected by the volume knob. Most often it is required to set the
preamplifier gain to Unity (Gain of 1). The REX allows the user to do so by using its FIXED gain
function.
Press the Function button six times.
The display will read: FIX OFF
Enter any desired number for the fixed gain on the selected input (see below).
UNITY gain for the REX preamplifier correspond to the following volume setting:
CNTS display mode
100 Counts
DBU
00.0dB
DBM
-20.0dB
Exit the programming mode by pressing and holding the Function button.
DISPLAY MODE programming
The volume display of the REX can be switched to work in any of the following three modes:
CNTS:
Relative volume counts with the range of 000 to 140
DBU:
Decibel readings with respect to unity gain (0dB).
DBM:
Decibel readings with respect to maximum gain (20dB)
NOTE: To avoid possible confusion, the SAME display mode setting applies to ALL inputs. It
is not possible, for example, to set one input to CNTS and another to DBU.
