• When all connections to the amplifier are made, turn all rotary controls down and switch
on the power and a power “ON” LED will illuminate. Turn BASS and TREBLE controls
to the 12 o’clock position (pointing straight up) and turn MASTER rotary control up part
way for testing.
• Ensure a signal is being fed to one of the line inputs 1, 2, 3, 4, 5, 6 or 7 and gradually
increase the volume control for that channel until the output is heard through the
peakers. Turn up the MASTER to the maximum required volume level and reduce the
channel volume control if necessary.
• Note: The initial test can be made using the built-in USB/SD/FM/DAB audio player. The
output of the amplifier is represented on the level meter LEDs and care should be taken
that the Red “0” LED is only lit momentarily during use. Anything longer than a short
flash of this LED may be indicating distortion or clipping of the output signal and the
MASTER should be turned down.
• If a microphone is connected to MIC2-4 input, make sure it is switched on and if it
requires phantom power, make sure this feature is enabled. Gradually increase its
volume control whilst speaking into the microphone until the required volume level is
reached. The microphone should not be able to “hear” the speakers, which can cause
feedback (squealing or Howling noise).
• If the VOX feature is enabled, audio playback through channels 2-6 will be reduced
in volume automatically when speaking into MIC 1, use its attenuator to increase or
decrease the mute level.
• In addition to channel and MASTER volume controls, there are BASS and TREBLE
EQ controls to adjust the tone of the overall output. At the 12 o’clock position, these
controls are applying no effect to the signal (no boost or cut). Moving the BASS control
clockwise boosts the low frequencies in the audio, whilst moving it anticlockwise will cut
these low frequencies. Likewise, moving the TREBLE control clockwise boosts the high
frequencies in the audio, whilst moving it anticlockwise will cut these high frequencies.
Adjust these EQ controls to suit the type of audio signal or compensate for the room
acoustics.
