MX30 OPERATORS’ MANUAL

Because the Gate is self-adapting to the programme dynamics, it should be possible to
obtain far more satisfactory results than are possible with conventional gates. Similarly,
do not assume that because the gate threshold LEDs flicker during a piece of quiet but
wanted material that it is having a detrimental effect. W hen it first comes into play, the
ratio of expansion is very low, so trust your ears!

Finally, set the Gain control to give the required output level using the level meter to
guide you. Avoid running at very high output levels as this reduces the available amount
of  signal  headroom  and  could  lead  to  distortion  in  extreme  cases.  Once  the  gain  is
correct, set the Peak Limiter Level control so that the limiter LED only lights briefly on
extreme signal peaks. Alternatively, set the Peak limiter Level to the desired value and
then adjust the compressor Gain control to ensure minimum limiter activity.
If required, the Gate may be used on its own with the compressor and limiter functions
disabled. The Peak limiter has no separate on / off control, but turning the Level control
fully  clockwise  will  prevent  any  unwanted  limiter  action.  To  effectively  bypass  the
compressor section turn the compressor Threshold up to its maximum of +20dB (fully
counter-clockwise), set the Ratio to its lowest setting of 1.2:1 and adjust the Gain to
approximately 0dB.
