8 Channel Dual-Mode Compressor/Gate with
iTS Hysteresis and Flexible Channel Linking
Compressors/Limiters
SQ1D
Intelligent Threshold Shift (iTS)
iTs operates in conjunction with the Gate Hold control to reduce false triggering of noise gates.
When signals (especially low frequency ones) are very close to the gate threshold, a gate can
repeatedly open and close on the programme material. iTS ensures that the gate remains open
by automatically adjusting the gate threshold downwards the moment the signal goes over the
threshold setting. When the signal eventually falls below the (new) temporarily adjusted threshold,
the iTS function resets, ready for the next gate opening. This hysteresis action results in more
decisive operation of the noise gates, and attack envelopes also start instantly and consistently,
even on signals that are only slightly over threshold.
Independent Side Chain Monitoring
SQ1D overcomes a common issue with many outboard dynamics processors, where the side
chain listen function is routed to the main output when engaged, which prevents mix engineers
utilising this essential function during a live performance. SQ1D features an additive console-style
Solo Bus which allows monitoring of the incoming signals at source and the  ne-tuning of the side
chain  lters. Dedicated input and output XLR connectors allow this bus to be cascaded between
multiple units and connected to a spare input channel or auxiliary return on the mixing console,
for easy and convenient monitoring by the mix engineer. A Solo In Place button is included which
will route the side chain signals directly to the audio outputs, a useful feature during the set-up
for a show.
Flexible Channel Linking
Adjacent channels can be linked in any combination for stereo or multichannel operation.
When any number of adjacent channels are linked, the linked channels all adopt the operating mode
(compressor or noise gate) of the left-hand channel of the linked group. This channel’s settings now
control all the members of that group, with only the make-up gain and Side chain  lter frequency
controls independent for optimising the action of the compressor or gate for each channel.
