WARNING
When the Unit is in Use
• Should the following irregularity be found
during use, immediately switch o the
power, disconnect the power supply plug
from the AC outlet and contact your nearest
Quest dealer. Make no further attempt to
operate the unit in this condition as this
may cause re or electric shock.
• If you detect smoke or a strange smell
coming from the unit.
• If water or any metallic object gets into
the unit
• If protect lights are illuminated or the clip
lights stay on for more than one second
• If the power supply cord is damaged
(exposure of the core, disconnection, etc.)
• To prevent a re or electric shock, never
open the unit case as there are high voltage
components inside the unit. Refer all
servicing to your nearest Quest dealer.
• Do not place cups, bowls, or other
containers of liquid or metallic objects on
top of the unit. If they accidentally spill into
the unit, this may cause a re or electric
shock.
• Do not insert nor drop metallic objects or
ammable materials in the ventilation slots
of the unit’s cover, as this may result in re
or electric shock.
When Installing the Unit
• Do not expose the unit to rain or an
environment where it may be splashed by
water or other liquids, as doing so may
result in re or electric shock.
• Use the unit only with the voltage
specied on the unit. Using a voltage
higher than that which is specied may
result in re or electric shock.
• Do not cut, kink, otherwise damage nor modify
the power supply cord. In addition, avoid using
the power cord in close proximity to heaters,
and never place heavy objects -- including the
unit itself -- on the power cord, as doing so may
result in re or electric shock.
• Be sure to replace the unit’s terminal cover
after connection completion. Because
high voltage is applied to the speaker
terminals, never touch these terminals to
avoid electric shock.
• Install in a well ventilated equipment rack
away from heat sources.

CAUTION
An all-pole mains switch with a contact separation of at least 3mm in each pole shall be
incorporated in the electrical installation of the building.
When Installing the Unit
• Never plug in nor remove the power supply
plug with wet hands, as doing so may cause
electric shock.
• When unplugging the power supply cord, be
sure to grasp the power supply plug; never
pull on the cord itself. Operating the unit
with a damaged power supply cord may
cause a re or electric shock.
• When moving the unit, be sure to remove
its power supply cord from the wall outlet.
Moving the unit with the power cord
connected to the outlet may cause damage
to the power cord, resulting in re or electric
shock. When removing the power cord, be
sure to hold its plug to pull.
• Do not block the ventilation slots front intake
or rear hot air outlet. Doing so may cause
heat to build up inside the unit and result in
re.
• Avoid installing the unit in humid or dusty
locations, in locations exposed to direct
sunlight, near heaters, or in locations
generating sooty smoke or steam as doing
otherwise may result in re or electric shock.
When the Unit is in Use
• Do not place heavy objects on the unit
as this may cause it to fall or break which
may result in personal injury and/or
property damage. In addition, the object
itself may fall o and cause injury and/or
damage.
• Make sure that the volume control is set
to minimum position before the power is
switched on. The possibility of a loud noise
produced at high volume when power is
switched on can impair hearing.
• Do not operate the unit for an extended period
of time then the sound is distorting. This is an
indication of a malfunction, which in turn will
generate heat and result in a re.
• Contact your dealer in regards to how to best
clean the unit. If dust is allowed to accumulate
in the unit over a long period of time, a re or
damage to the unit may result.
• If dust accumulates on the power supply plug
or in the wall AC outlet, a re may result. Please
clean the connection periodically. In addition,
insert the plug into the wall outlet securely.
• Switch o the power, and unplug the power
supply plug from the AC outlet for safety
purposes when cleaning or leaving the unit
unused for 10 days or more.
Doing otherwise may result in re or electric
shock.

General Description
The compact QM 1000P amplier is a 2-way
stereo combination sub bass and satellite
composite amplier powered with three
internal ampliers. It can power up to four
satellite speakers and two sub bass boxes.
It is designed as a complete multi-way
amplier package for mobile live sound and
permanent installation venues. The QM 1000P
is a compact alternative to the size, bulk and
expense of a conventional multiple amplier
rack and system controller where a full range
system of medium power is required.
Connect almost any combination or
type of speaker
Almost any combination of satellite or sub bass
speakers can be connected and function with
the QM 1000P amplier. User adjustable high
and low pass lter networks and a master limiter
allow for a variety of speaker box options and for
a variety of live and installed sound applications.
The adjustable master output limiter can be set
to protect lower powered speakers if the owner
wishes to use an alternative speaker combination.
Each internal amplier is also equipped with soft
knee clipping protection as an extra precaution.
Your choice of QM series speakers
The ideal combination for the QM 1000P is a pair of
QM600S 15” sub bass boxes and two or four QM108
/QM10DC speakers. The QS150/230/300i speakers
will also function well with the QM 1000P and the
satellite ampliers can be switched to full range
operation for 12” and 15” speakers.

. Sub bass high cut
This control can be used to change the bass
crossover frequency from 80 Hz to 200 Hz. For
deep sub bass response select 80 – 100Hz.
. Limiter control
The threshold level where system limiting begins
to occur is adjustable and can be set to protect
low power handling speakers or as a max SPL
adjustment when noise level needs to be limited for
environmental reasons.
. Status indicators
There are indicatiors for signal presence, clip/
compression and power. The QM 1000P soft knee
limiting will prevent severe amplier clipping, but
when a mixer signal source is driven into severe
distortion, some audible amplier clipping may
result.
. Satellite volume level controls
L + R input and sub bass volume controls drive the
satellite and bass ampliers outputs.
. Sub Volume
Volume control for the internal 950 watt (4Ω) mono
sub bass amplier. When used in conjunction with
the Master L&R input, a balance between the low
frequencies of the sub bass and the mid high output
from the satellite speakers can be optimised for the
venue and the music source.
. Power on/o
Operational Note:
For tuning and adjusting the bass sound, set high
cut for adjustment of the upper bass cross-over
frequency fowr the Sub bass amplier set to below
100 Hz for low bass, above 125 for a higher range of
bass frequencies.
Subwoofer volume:
To control sub bass volume level. By increasing
input volume and adjusting subwoofer volume,
a balance the satellite speakers and the sub
bass can be achieved.

. Satellite high pass crossover
The satellite speakers can be powered with full
range signal or a cross-over to sub frequency of
80Hz or 120Hz can be selected. For 8” speakers,
120Hz is suggested. When using 10”-12” speakers,
80Hz is be preferable and high powered 12” or 15”
speakers can be set to full range.
. Inputs
Connect signal leads from your mixer (master
left/right, line out, to the balanced inputs using
XLR mic leads. XLR connectors to be wired as
follows: 1 ground, 2 +, 3 -.

. Outputs
Speakon output connectors on rear wired L&R
pin 1+ pin1-. Neutric NL4 or NL2 connectors
are recommended. The total impedance per
output should not be below 4Ω (Ohms)
(3.7Ω DC resistance). 2 x 8Ω satellite
speakers and 1 x 8Ω bass speakers can be
connected per amplier output.
