Owner's Manual

Input 3

Input 3 consists of stereo summing inputs, suitable for connection to the output of CD/DVD players, etc.

Mute Sensitivity Control

VOX Mute Sensitivity Control adjusts how sensitive the mute send circuitry on Input 1 reacts. Setting the control fully counter-

clockwise will lower the sensitivity, where a higher amplitude signal will be required at Input 1 to trigger the mute send circuits.

Fully clockwise will raise the sensitivity of the mute circuits, where a lower amplitude signal will trigger a mute send. Careful

calibration of this control may be required to fully utilize the capabilities of the mute circuits.

70.7V / 100V Speaker Connections

For loudspeaker connections, follow the labeling paying special attention to the polarity or proceed to the Limit LED & Load

Considerations section. Note: Do not short the terminals together or damage may occur.

Global IEC AC Mains Power Receptacle

The MA Models support global power sources from 100V - 240V 50/60Hz. The package contains a cord that has an international

IEC connector to a 120V USA type plug. It may be necessary to replace the removable power cord to meet your AC mains plug

type used in your country. Note: It is not required to change the fuse for the different AC mains voltages.

Remote Mute Connector

Shorting the Remote Mute terminals will mute inputs 2 and/or 3, depending on how their dipswitch settings are set for switch

positions 1 and 2 labeled "Mute Rec"/"Input 2" & "Input 3". In the "ON" position, the corresponding channel will be muted when

the terminals are shorted together. This connection is usually done via remote switch on a microphone.

Wiring the MA40G/MA60G

Speaker Outputs - Use 2 conductor unshielded wire of the appropriate gauge. If you are unsure about this, contact Atlas Sound Tech

Support at 1-800-876-3333. Make sure you know how many speakers you need and what tap value you intend to use.

Mic/Line Input - 2 conductor with shield for low level signals of 20 - 22-gauge is best. Maintain the proper polarity, + to +, – to – , and

shield to ground.

Unbalanced Inputs and Outputs - Pre-made RCA cables can be purchased from vendors to simplify interconnection to external devices.

Security Cover Option

In order to prevent unauthorized operation of the MA40G & MA60G, optional security covers are available which take the place of the

front panel knobs. After the MA amplifier has been installed and is operating as desired, grasp the front panel knobs and pull straight out

from the front panel. Replace the knobs with security covers, Atlas Sound part number MPVCC-5, available in quantities of 5.

Rack Mount Kit Option

The MA40G & MA60G can be rack mounted as a single unit or with two units together. To do so a PA702RMK Rack Mount Kit needs to

be purchased from Atlas Sound.
