IMPORTANT!
Use positive gain with care as the unit does not monitor overloads. If in
doubt, use Maximise instead.
With Balance set central (i.e. L 0dB, R 0dB), no gain is applied to either
channel. Panning to the right attenuates the left but does not amplify the right
channel and vice versa. This arrangement helps avoid overloads.
To set the balance, select Balance then press Set. Turn the rotary control to
adjust the balance anywhere between 0.0 and -6.0dB on either channel in
0.2dB steps. Adjustment beyond -6.0dB mutes that channel. Press Set again to
exit.
Maximise is a feature that makes best use of the available dynamic range. The
dCS 974 keeps a running record of the maximum amplitude of the signal.
Maximise can then apply the exact gain to ensure the highest signal peak noted
is boosted to full scale.
The maximum gain that may be applied is +12dB. If the correction exceeds this,
+12.0dB of gain will be applied. Please note that Maximise cannot correct
overloads. Maximise can be run repeatedly if you have a lot of gain to max up.
do this: At the start of the track, select Maximise then Reset max hold and press Set.
do this: At the end of the track, select Maximise then Maximise! and press Set. The
gain correction will be applied.
do this: Replay the track and the gain will be Maximised.
Select Maximise then Display max hold and press Set to see the current
peak signal record.
Swap Channels
This allows the left and right channels to be swapped. For normal operation,
select Normal and press Set. To swap channels, select Swapped and press
Set - the L/R Flip LED will light up.
Phase
The options for Phase are:
Normal Select then press Set. Outputs are in phase with
inputs. Both Phase indicators are off.

with input, Right is in phase. Left Phase indicator
lights.
Right Inverted Select then press Set. Right channel is out of
phase with input, Left is in phase. Right Phase
indicator lights.
Both Inverted Select then press Set. Both channel outputs are
out of phase with inputs. Both Phase indicators
