Intr uction od
Thank you for choosing a Citronic H-series power amplifier as part of your sound reinforcement system. These amplifiers
use hybrid class-H architecture to offer high power output in a compact lightweight form factor. Please read this manual ,
full and follow the instructions to achieve the best results from your amplifier and to avoid damage through misuse. y
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. ed
• Check that the 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 airflow 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 (18, 19) using good quality Speakon® leads 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 = TOTAL impedance. … … 1/
Therefore… Ω + 8 8Ω = total 4Ω
4 4 total Ω + Ω = 2Ω
8Ω + 8Ω 8Ω + 8Ω = + total 2Ω
Th rear panel has a MODE switch (13), which determines the way that the amplifier operates. The standard operating e
mode is , with each input feeding its relevant speaker output. STEREO
PARALLEL mode sums both inputs together in mon so that each amplifier channel receives a mix of both inpu o ts.
Also, both channels can be combined to drive a single load at higher power by selecting mode. In this mode, BRIDGE
the input is on channel 1 and the output from the speaker connecter as indicated on the rear panel ( red to is OUT 1 wi
pins 1+ and 2- ) WARNING The minimum load for BRIDGE mode is 4 .– Ω
Below the MODE switch is a SENSITIVITY switch (15), which has 3 settings for different input levels.
The standard setting is 1.0V and further settings for 1.4V and 2.0V higher level inputs will reduce the input sensitivity.
When set to , th LF PROCESSING switch provides a 2dB boost at 100Hz for enhanced bass response. “on”e
Connect each signal input from mixer or other line level source via XLR 6.3mm jack connectors to the combor o
connectors (11, 17) on the rear panel using good quality signal leads. Depending on output level of the mixer, select the
appropriate sensitivity on the rear panel. Wiring for balanced or unbalanced inputs are as follows …

Each channel input also has a corresponding XLR e output (12, 16) for linking onto further amplifiers, necessary. lin as
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 supply (9) ensuring the IEC lead is earthed, in good condition and connected securely. ,
With Channel 1 + 2 controls (2 6 turned fully down, switch on the power to the amplifier (7). 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 ampli channel level controls to the fier’s
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.
The LED indicators for each channel (3, 5) are as shown opposite.
In normal operation, the indicators will be on and the indicators will POW SIG

If the input signal is overloading the amplifier, this clips above the available power limit. “ ”
When this happens, the indicators will light. CLIP

However if they light for any longer than a brief instant or very frequently, the input level should be reduced or channel ,
level controls on the front panel should be turned down until the regular clipping is eliminated.
If the internal protection circuitry detects a fault in the speakers or amp, the channel(s) will enter protect mode and
PROT will illuminate on the front panel to show this. Switch the amplifier off and check the entire system (including
speaker leads) before powering up again. If still in Protect Mode, seek advice from qualified service personnel.
