Introduction
Thank you for choosing a Citronic PLX series power amplifier as part of your sound reinforcement system. This high
output amplifier is 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

Operation
Connect speaker cabinets to channel outputs using good quality leads via the SPK connector or binding posts and ensure
that the combined load on each channel is no lower than 2 Ω.
For speaker loads connected in parallel 1/speaker impedance + 1/speaker impedance = 1/TOTAL impedance … …
Therefore… Ω + Ω = Ω 8 8 4 total
4 4 2 total Ω + Ω = Ω
8Ω + 8Ω 8Ω + 8Ω = Ω+ 2 total
Both channels can be used to drive a single load at the combined volume of each by switching to BRIDGE mode. In this
mode, the input is on channel 1 and output from CH1 SPK connecter (pins 1+ and 2-) or across the red terminals as “+”
indicated on the rear panel - WARNING - Minimum load for bridge mode is 4 Ω
Connect each signal input from mixer or other line level source via the XLR connectors on the rear panel using good
quality signal leads. Depending on output level of the mixer, select the appropriate sensitivity on the rear panel.
For protection in high power situations, the onboard COMPRESS function may be switched in to protect from overload.
In situations with excessive mains coming through the speakers, it may help to switch the GROUND to the LIFT hum
position. This is may help in some situations but otherwise, it is preferred to be switched to GND.
XLR inputs and outputs for each channel are wired in parallel, allowing signal to be carried forward to further amplifiers.
Connect the amplifier to a mains outlet, ensuring that the IEC lead is earthed, in good condition and connected securely.
With channel gain controls turned fully down, switch on the power to the amplifier. This unit -has a “soft start” function
which makes some checks before engaging power to the amplifiers, which may take a few seconds.
With mixer (or other signal source) levels turned down, gradually increase the amplifier’s channel level 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, green “SIGNAL” LEDs will illuminate to show when a signal is present and “CLIP” LEDs illuminate if the yellow
output is reaching clip level. If the red CLIP LEDs illuminate more than very briefly, reduce the volume until they hardly
light up at all.
If the internal protection circuitry detects a fault in the speakers or amp, the channel(s) will enter Protect Mode and red
“PROTECT” LEDs will illuminate on the front panel to show this. Switch the amplifier off and check the entire system
(including leads) before powering up again. If still in Protect Mode, seek advice from qualified service personnel.
Before powering down, turn the channel gain controls fully down to avoid loud noises when switching off.
