MACHINE OPERATION
1. After connecting all audio sources and powering on the mixer amplifier, adjust the level of each
audio input to achieve the desired “mix”. Care should be taken to when adjusting microphone
input volumes and the master volume, adjust both of these in small increment’s to avoid feedback
(howl around). The goal is to achieve a clear balance between music and voice ensuring an-
nouncements can be clearly heard.
2. The Telephone and Microphone input No.1 feature adjustable voice operated override (VOX),
this will mute all other inputs. After 3 seconds of no signal to the TEL or MIC1 inputs the other
inputs will return to their original state. The VOX mute time can be adjusted on the rear panel. The
TEL input has highest priority, followed by the MIC1.
3. The Clever Acoustics amplifiers all feature output VU meter’s with PEAK indication. Should the
PEAK indicator illuminate (flashing) the output of the amplifier is too high, turn the master volume
anti-clockwise to reduce the output.
4. The Clever Acoustics amplifiers all feature protection with LED indication. Should the PRO-
TECT indicator illuminate, turn the master volume control anti-clockwise fully and switch off the
amplifier for 15 seconds as the amplifier may have entered PROTECT mode temporarily due to a
peak signal, care should then be taken to ensure all input levels are set correctly. If the amplifier
persists to enter PROTECT mode the amplifier should be switched off and left to cool for 5-10
minutes before switching back on. If the PROTECT indicator remains lit this indicates a problem
with the amplifier or amplifier load (ie Short Circuit).
5. Speaker & Amplifier systems can produce high sound pressure levels, please operate all
controls with caution to ensure people are not exposed to excessive or dangerous sound pressure
levels.
