Page 6: Rack Installation
Rack installation Rack Installation The MA Series are rack mountable. The rack you use should be a Double Door Rack where you can open the front and rear panel. When mounting the amplifier into the rack, please make sure that there is enough space around the amplifier. Be careful when mounting the amplifier into the rack. Put the heaviest products into the lower part of the rack. The front panel is not designed to absorb acceleration forces occuring during transportation. Inputs Short cables runs improve the sound quality remarkably. Input cables should be short and direct, since high frequencies will mostly be absorbed if the cables are unnecessarily long. Besides that a longer cable may lead to humming and noise problems. If the cable runs are unavoidable, you should use balanced cables. Outputs The high damping factor of your amplifier supplies a clear sound reproduction. Unnecessarily long and thin cables used for low impedance (4-16Ω) speakers will influence the damping factor and thus the low frequencies in a negative way. In order to safeguard good sound quality, the damping factor should lie around 50. The longer a cable has to be the thicker it should be. For longer cable runs please ensure the 100V outputs are used for 100V speakers. Connect your speaker systems via the speaker terminals (COM = -VE) Examples: 1) COM + 4-16Ω 2) COM + 70V 3) COM + 100V Note: Please do not use more than one pair of output terminals. Connections To The Mains Before connecting the amplifier to the local mains voltage outlet should be checked to ensure the available supply is 240V~AC 50Hz. This product is CLASS1 and requires a protective mains earth to be connected at all times. DO NOT remove or disconnect the earth. -
Page 7: Machine Operation
Machine operation 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 announcements can be clearly heard. 2. Microphone input No.1 features adjustable voice operated override (VOX), this will mute all other inputs. After 3 seconds of no signal to MIC1 inputs the other input will return to their original state. The VOX mute level can be adjusted on the rear panel. 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 PROTECT indicator il- luminate, 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. The Clever Acoustics amplifiers all feature protection with LED indication. Should the TEMP (over temperature protection) indicator illuminate, turn the master volume control anti-clockwise fully and switch off the amplifier for 15 seconds as the amplifier may have entered TEMP (over temperature protection) mode temporarily due to the internal temperature reaching the preset limit, care should then be taken to ensure all input levels are set correctly and that all ventilation slots are clear of obstruction. If the amplifier persists to enter TEMP mode the amplifier should be switched off and left to cool for 5-10 minutes before switching back on. If the TEMP indicator remains lit this indicates a problem with the output level (ie bass heavy music), amplifier cooling or amplifier load (ie Short Circuit). 6. 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. www.cleveracoustics.co.uk Mixer Amplifier series User Manual... -
