CHAPTER 1 DS101 NOISE GATE FOR THE 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.

CHAPTER 2 DRAWMER CONTROL DESCRIPTION The DS101 noise gate incorporates many impressive features, many pioneered by Drawmer, which are invaluable to the sound engineer and not found on conventional noise gates: • Variable high-pass and low-pass filters for ‘frequency conscious’ gating, with ‘Key listen’ facility. • Comprehensive envelope control, attack, hold, decay and range. • Ultra-fast response time. • ‘Traffic light’ display giving clear indication of gate status as well as Threshold Metering.
Decay 2mS to 4 Seconds. Once the signal has fallen below the Threshold and the Hold time has expired Decay determines the rate at which the gate closes. Range -80 to 0.0 dB Sets the amount of attenuation applied to the input signal when the gate is closed, enabling the gate to be used to remove unwanted signals entirely, or simply to attenuate signals which are too loud. When Duck mode of operation is enabled, the Range control sets the level to which the signal will be reduced when open (triggered).
DRAWMER The Key Filters Source Switch Ext/Linked/Internal With no LED lit the source comes from the ‘Internal’ signal. In the Ext position the gate responds to the signal dynamics of another, independent signal as plugged in via the 1/4” jack. This jack works in the same way as the ‘Key Input’ jack of the DS201, DS404 or DS501. Using the innovative optical infra red triggering mechanism linking can be acheived regardless of the 500 series rack that you use.
Key Listen Switch In normal operation, the filter only affects the way the Gate responds (opens) to the incoming programme material - it does not have any direct effect on the output signal, but when Key listen is enabled the effect of the key filter on the programme material is heard at the output - the audio signal is not routed through gate.
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.
will drop and then recover. It is usual to select a fairly fast Attack time, with a slow Release time of a second or so - this will react quickly and then bring the music level back up slowly and smoothly, and is hence less disconcerting to the listener 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.
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. In extreme cases restricting the Range of the Gate to about -15dB will adequately reduce the noise during pauses but not too dramatically.
the high frequency control to 3kHz or so. The object is to remove or reduce the contribution from the hi-hat whilst retain as much of the snare sound as possible. It’s likely that the Threshold will have to be re-adjusted, as the level may have to be quite high, and you will have to be careful not to miss the quieter hits, but the hi-hat should be gated completely, with no unwanted false triggering.
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.
