General Description
The QM3/QM4 powered speakers are a two
way active bass reflex design suitable for
mobile and installation use.
Hybridtec Amplifier Technology
The amplifier power is supplied by Quest
Engineering's new "Hybridtec" digital class D
and analogue class A/B amplifier system. The
Hybridtec amplifier is controlled by an internal
analogue system. Simplified controls on the
rear of the QM3/QM4 make operation easy.
The QM3/QM4 features an XLR input, XLR
link output, gain control, bass/treble cut and
boost, and input mic/line sensitivity.
Individually colored LED indicators show mic/
line settings and signal/peak presence.
The QM3/QM4 is a multi-purpose loudspeaker
that can be used as a front of house system
or as a powered foldback monitor. The cut
and boost rotary EQ controls can be adjusted
to make basic alterations to the sound.
Though maximum boost should be avoided at
high power levels.
The Hybridtec design saves weight, lowers
potential heat generation and also improves
sonic performance. A limiter monitors RMS
power for excessive input level.
Limiters and compressors are not a substitute
for sensible operation. The system will
sound its best when mixers and other signal
processors are not driven into distortion.
The design characteristics make the QM3
and QM4 suitable for both full range use or
as the Mid-High component of a multi way
system with bass enhancement. Coupled with
a Quest Engineering compact subwoofer,
the QM3 and QM4 can act as part of a point
source multi way system for full range sound
at medium to high sound pressure level.
Installation
Temporary installation is possible with the
addition of a 35-36 mm speaker stand.
Accessories
An optional transit carry bag is available
for the QM3/QM4. Made from rugged black
canvas to protect your investment.
Solid Build Construction
The QM3/QM4 is well suited to all
professional applications. The high grade
lightweight birch cabinet is specially
engineered to withstand demanding use
and the heavy gauge power-coated steel
grill ensures the driver and horn are always
protected.
