8 Channel Dual-Mode Compressor/Gate with
iTS Hysteresis and Flexible Channel Linking
Compressors/Limiters
SQ1D
Architecture & Engineering Speci cations
The dynamics processor shall provide eight complete channels of either compression or gating, with push button selection and LED status
indication of operational mode on an individual channel basis.
The dynamics processor compressor section on each channel shall provide for adjustment of threshold, make-up gain, attack and release times
and compression ratio. There shall be push button selection of RMS or peak-sensing responses and push button selection of Soft or Hard knee
mode on each channel.
The dynamics processor gate section on each channel shall provide for adjustment of threshold, attack, hold and release times and gate range.
The dynamics processor threshold, attack and release controls shall be operable by the same rotary control knobs in compression and
gating modes. Control of ratio and range shall be performed using the same rotary control knob. There shall be individual rotary control knobs
for make-up gain and gate hold.
The dynamics processor shall have a six-segment input level meter and a ten-segment attenuation depth meter (to show the gain reduction
being applied in both compression and gating modes) for each channel.
The dynamics processor shall have a sidechain band-pass lter for each channel with a rotary control knob for frequency control, which
shall be enabled by a dedicated push button switch. Each band-pass lter shall have wide and narrow bandwidth settings, selectable by a
push button switch. There shall be provision for an external sidechain input for each channel, individually selectable by the external key push
button switch with LED status indication.
The dynamics processor shall have a bypass switch on each channel to set the signal path to unity gain with LED status indication.
The dynamics processor shall have a solo switch for each channel with LED status indication that sends the sidechain signal to the solo bus
output connection.
The dynamics processor shall have a solo bus input connection to allow multiple dynamics processors of the same type to be chained together
to form a common solo bus output.
The dynamics processor shall provide the solo bus input and output connections on balanced XLR connectors.
The dynamics processor shall have a side chain solo in place switch with LED status indication to change the function of each solo switch,
when selected the sidechain signals for each channel shall be sent to the respective channel output connectors instead of the solo bus output
connection.
The dynamics processor shall have the ability to link the operation of any number of adjacent channels, which shall all be summed into the
sidechain of the left-hand linked channel which shall control the gain of each of the linked channels. The selection of either compression or
gating for the left-hand linked channel shall override the push button settings for all channels linked to it.
The dynamics processor shall have an LED for power on indication.
