Operation
Connect speaker cabinets to speaker outputs (8, 9 or 10 using good quality leads and ensure that the )
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 illuminate ) (2)
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.
