SQ1D
Frequency-Selective Compression and Gating
Each channel side chain is equipped with a selectable bandpass  lter with wide and
narrow responses. This powerful feature greatly extends the capabilities of the multiple compression
and gating modes. Frequency-selective compression is a very e ective and creative alternative to
equalisation, with the wide bandpass  lter response being ideal to enhance the essential character
of an instrument, allowing it to stand out in a mix without the use of harsh- or unnatural-sounding
boosted EQ responses. The SQ1D can also be used as a frequency-selective De-esser by selecting
the narrow bandpass  lter response to reduce sibilance or other undesirable artefacts from vocals,
or to remove speci c resonances from instruments or programme material. When the SQ1D is
operating as a noise gate, the side chain  lter can be used to select the key frequency component
in programme material that can be used to trigger the operation of the gate, especially useful with
drums kits and percussion instruments.
The  exibility of the side chains is enhanced by the inclusion of a dedicated side chain input for each
channel on a balanced ¼ " TRS connector.
Built for the Road
Featuring a rugged steel 3U rackmount enclosure, the SQ1D is designed for the rigours of live
concert touring. Premium Neutrik XLR connectors are used to ensure reliable audio connections,
night after night.
