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 -6.0dBon 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.
