Page 5: 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 on any one output zone. 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... -
Page 6: Operation Instructions
Operation instructions Initial Start Up Procedure • Reset all “Level” or “Volume” controls to the “0” position on the front panel. Reset the BASS and TREBLE controls to the centre point. • Reset CH1 thru CH5 gain controls & TEL level control on the rear panel to the “0” position. • Connect the audio sources & mains power input. • Switch on the amplifier using the mains switch on the front panel. The LED indicator (13) will illuminate BLUE if the amplifier is ready for use and working correctly, if the indicator illuminates RED this indicates the amplifier is under PROTECT status. • Adjust CH1 thru CH5 gain controls to match the input signal levels between different sources CH1 to CH5 Operation (note: CH1 thru CH5 feature the same operation) BASS control: BASS control offers tonal adjustment for the low frequency, turn clockwise to increase and anti-clockwise to decrease. TREBLE control: TREBLE control offers tonal adjustment for the high frequency, turn CH 2 clockwise to increase and anti-clockwise to decrease. BASS TREBL E VOLUME (LEVEL) control: VOLUME (LEVEL) control offers adjustment for the LEVEL... - Page 7 Operation instructions MP3 Player / FM Radio Operation: POWER: The onboard MP3 Player & FM radio may be powered up or down independent of the main amplifier. Press the power switch to power on or power off the MP3/FM Radio. MODE: Press the mode button to select FM Radio, SD Card or USB. PP/SCAN: The FM radio tuner features automatic tuning, press the PP/SCAN button to activate the scan function. NEXT: Press the NEXT button to skip music tracks next when using the SD Card or USB. PREV: Press the PREV button to skip music tracks previous when using the SD Card or USB. EQ: Press the EQ button to adjust the equaliser settings for the SD Card/USB or FM Radio. VOL +: Press the VOL + button to increase the volume for the SD Card/USB or FM Radio. VOL -: Press the VOL - button to decrease the volume for the SD Card/USB or FM Radio. POWER 97.60 MODE NEXT VOL+ PP/SCAN PREV VOL- SD/MEDIA Priority Paging Function: MIC1 features the highest priority in. 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. 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.

Speaker impedances must be measured using a true impedance meter, do not standard multimeters. WARNING! Be sure to attach the supplied terminal cover attached after connection. Because high voltage is applied to the speaker terminals, care should be taken never touch these terminals to avoid electric shock.
