from the voltages listed on the back panel or the
recommended, or included, power supply of the
product.
2. Operation from other voltages other than those
indicated may cause irreversible damage to the
product and void the products warranty.
3. If you are unsure of the correct operational
voltage, please contact your local distributor and/or
retailer.
4. Class I Equipment. This equipment must be
earthed. The power plug must be connected
to a properly wired earth ground socket outlet.
An improperly wired socket outlet could place
hazardous voltages on accessible metal parts.

GENERAL DESCRIPTION
DIMENSIONAL DIAGRAM
The Soundmask GQ is an App-controlled single rack
mounted 2, 4 or 8 channel digital sound generator,
equalizer, zone distributor and amplifier, with an
output of 50 watts RMS per channel @ 8 ohms.
It features individual channel level control for each
channel via the Android App and stereo banana jack
outputs to connect the Soundmask transducers
(SM-T-1200 & SM-TC-1265 series) which daisy chain
in rows of up to 100 transducers per channel. The
Soundmask GQ delivers uncoloured signal direct to
the transducer.
The SM-GQ-2 is capable of servicing up to 200
transducers (100 per channel), and each channel
is its own zone, allowing 2 individual zones per unit
(controlled via App). The SM-GQ-4 and SM-GQ-8 are
capable of servicing up to 400 and 800 transducers
respectively via their 4 and 8 zones, respectively.
The unit connects to mains power via an external power
supply. A compatible power cord is supplied with the
unit. The voltage input is 100-240VAC, 50-60Hz.
