Using The Dbz-48; Mono Operation - Apex Digital dBZ-48 User Manual

Using the dBZ-48

Using the dBZ-
Operation of the dBZ-48's input and output sections is entirely
straightforward, and requires only correct adjustment of the
respective level controls.
Start with all the front panel rotary controls fully anticlockwise.
Connect the stereo input source(s) to IN A and IN B and the
stereo outputs to their respective amplifiers (or other signal
processing) as appropriate. With the programme material
present, rotate the input level controls until the second (+6dB)
LEDs flash on the loudest peaks, but so that the red peak LEDs
do not illuminate. Then rotate the output level controls for each
output channel in turn to obtain a similar display on each pair of
output LED meters.

Mono operation

The MONO buttons on the input channels should be used if the
input in question is being fed from a mono source. In this case,
the input signal may be applied to either the L or R input.
If any of the outputs are to be used in mono (e.g. with the
dBZ-48 in use as a zoner, it may not be practical for some
room areas to support effective stereo operation), the output
channel MONO buttons may be used to make an L+R sum of
the stereo input signals available at both L and R outputs of a
channel. This does not compromise the other output channels
being used as stereo, of course.
