User Manual

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

NOT remove or disconnect the earth..

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)
1)

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

clockwise to increase and anti-clockwise to decrease.

VOLUME (LEVEL) control:

VOLUME (LEVEL) control offers adjustment for the

corresponding input channel, turn clockwise to increase and anti-clockwise

to decrease to reduce the volume.

MUTE button:

Each channel input (CH1 thru CH5) may be muted by pressing the

MUTE button. The button features LED illumination when muted.

Z1 to Z4 Zone Selector buttons:

Each of the CH1 to CH5 input channels can be

routed to any combination of the four output zones. The zone selector buttons

feature LED illumination, the LED will illuminate if the zone is selected.

VOLUME (LEVEL) control:

VOLUME (LEVEL) control offers adjustment for the

corresponding output channel, turn clockwise to increase and anti-clockwise to

decrease to reduce the volume.

MON button:

The MA 4060MP and MA 4120MP amplifiers both feature a Monitor

output function for status confirmation purposes. Select the MON button on the

desired channel to activate the Monitor function. The Monitor output features a

Volume (Level) control.

Output VU Meter:

Each of the five outputs (Z1 to Z4 and MON) feature LED VU

meter plus CLIP and PROTECTION status indicators. The CLIP LED will illuminate to

indicate when the audio signal is too high, in this instance reduce the VOLUME by

turning the volume control anti-clockwise. The PROTECT LED will illuminate if the

amplifier detects a fault or a problem with the output circuit.

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.

3. 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).

4. 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.

• Both the 4 - 16Ω and 100V terminals cannot be used at the same time.

• Impedances indicated in the figures represent the total speaker system (load) impedances.

• Loads presented to the amplifier must be equal to or greater than listed above. 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.

All speaker connections should be made using bare wire or suitable insulated

crimp terminals. Please ensure no loose strands are present as these may

short across terminals causing damage to the amplifier.
