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 VK-40 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 VK-40 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 VK-40 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.
