Adjusting amplifier power
The M51 can be equipped with
two outputs with different power
levels; either an analogue
output [5 x 60 watt] or the more
powerful digital alternative [5 x
200 watt].
If you want to connect speakers
to the digital output, which are
not set up for this power level,
there is a menu point in the
Setup menu where you can
adjust the output power level.
The three screenshots below
show you three of the six power
steps that can be selected:
The power adjustment can be
used for the analogue and the
digital outputs and is applied
equally over all five channels.
The following table shows you the
relative volume reductions and the
remaining power:
Full - 100%
-1 dB - 90%
-2 dB - 80%
-3 dB - 71%
-4 dB - 63%
-5 dB - 56%
-6 dB - 50%
Example Analogue output
Reduction: –2 dB
Power: 80% of 60W = 48W
Example: Digital output
Reduction: –2 dB
Power: 80% of 200W = 160W
Volume display
The reduction in volume is
visible in the display field if you
select a volume that is higher
than the reduction; the volume
bars flash in the corresponding
area as shown in grey in the
following graphic:
