500 SERIES RACK SYSTEM The Industry-Standard High-End Noise-Gate comes to the 500 Series! The DS101 is the first noise gate designed specifically for the 500 Series rack system and takes its place alongside the Drawmer family of industry standard Noise Gates, such as the DS201, DS501 and DS404. Anyone familiar with those units will immediately be at home with the DS101.
Whilst looking down into the 500 series rack ensure that the DS101 card edge connectors line up with the EDAC type connector of the rack, then gently push the DS101 in place keeping it as square as possible until it is fully located. Do not use excessive force! Tighten the two front panel screws.

‘Key Filters’ section and the Threshold of the adjacent left channel - if this is also linked this continues until the Master DS101 is reached. Note that only adjacent channels can be linked. The Attack, Hold, Range and Decay controls, as well as the Duck and Bypass switches remain indepentent.
If the ends of sounds are being truncated, then a longer Decay time may help. On the other hand, if unwanted noise is audible after the wanted sound has ended, a shorter Decay time may be more appropriate. DS101 - Noise Gate for 500 Series Systems...
DRAWMER Noise Gate Operation There are circumstances when the programme material is corrupted such as, in a multi-miked drum kit setup, some hi-hat will inevitably leak into the snare microphone, some snare drum into the kick drum microphone and so on. Equally, on location, you may experience problems due to wind or traffic noise or close-by conversation.

In addition to voice over applications, the Duck function of the DS101 may also be used to treat a signal where the peaks are too loud and require attenuating. In this application, ‘Duck’ and ‘Internal’ (i.e source switch not selected) modes should be selected, and the ‘Range’...

DRAWMER Difficult Material To Gate If noise contamination is serious enough to be evident even during moderately loud programme material, then simple gating will do little to help. Indeed, the very fact that the Gate produces silence during pauses can make the noise content of the programme material even more apparent.

DRAWMER Tighten Vocals and Brass Sections A clever use of the external triggering via the Key input is making particular parts start and finish at the same time. Regarding vocals and brass sections performers may start a fraction early, some end a fraction late. Link the channels and use the backing vocal/trumpet with the best timing as the trigger for the gate to tighten the timing up.
