Introduction
Thank you for choosing the QTX Q series power amplifiers as part of your sound reinforcement system. These
amplifiers are designed to offer high quality, dependable service for mobile and installed systems. Please read
this manual fully and follow the instructions to achieve the best results with your new purchase and to avoid
damage through misuse.
Warning
To prevent the risk of fire or electric shock, do not expose any of the components to rain or moisture.
If liquids are spilled on the casing, stop using immediately, allow unit to dry out and have checked by qualified
personnel before further use. Avoid impact, extreme pressure or heavy vibration to the case
No user serviceable parts inside Do not open the case refer all servicing to qualified service personnel. – –
Safety
Check for correct mains voltage and condition of IEC lead before connecting to power outlet
Ensure speaker leads are good condition with no short connections or damaged plugs
Check impedance of speaker loads do not exceed the minimum stated load for the amplifier
Do not allow any foreign objects to enter the case or through the ventilation grilles
Placement
Keep out of direct sunlight and away from heat sources
Keep away from damp or dusty environments
When rack-mounting, ensure adequate support for the base of the amplifier and firm fixings for the front
Ensure adequate air-flow and do not cover cooling vents at the front and rear of the amplifier
Ensure adequate access to controls and connections
Cleaning
Use a soft cloth with a neutral detergent to clean the casing as required
Use a vacuum cleaner to clear ventilation grilles of any dust or debris build-ups
Do not use strong solvents for cleaning the unit
Unpacking

Operation
Connect speaker cabinets to speaker outputs (8, 9 or using good quality leads and ensure that the 10)
combined load on each channel is no lower than 4Ω (for speaker loads connected in parallel, Ω + Ω = 8 8 4Ω)
Connect each signal input from mixer or other line level source via the jack (11) or RCA (12) connectors on
the rear panel using good quality signal leads. The jack and RCA inputs are wired in parallel, so whichever is
not used for the input signal can be used to connect onto further amplifier inputs.
Connect the amplifier to the mains outlet, making sure that the IEC lead is earthed, in good condition and
connected securely. Ensure the correct voltage is selected on the rear panel voltage selector (7)
With channel gain controls turned fully down, switch the power switch (4) . (3) on
With mixer (or other signal source) levels turned down, gradually increase the amplifier’s channel gain controls
to the required level (normally full) and then gradually increase the signal level from the mixer or sound
source until sound can be heard through the speakers and then continue increasing up to the required level.
During use, the Signal LEDs (5 will illuminate to show that the signal is present. If the Clip LEDs (2) illuminate )
more than very briefly, reduce the volume until they hardly light up at all. This will avoid distortion or
“clipping” through the speakers.
Before powering down, turn the channel gain controls fully down to avoid loud noises when switching off.
