4. Input 1 Gain
Input 1 level control potentiometer varies the amplitude of the signal fed into the amplifier. Turn clockwise to increase and
counter-clockwise to decrease the signal level.
5. Input 2 Gain
Input 2 level control potentiometer varies the amplitude of the signal fed into the amplifier. Turn clockwise to increase and
counter-clockwise to decrease the signal level.
6. Input 3 Gain
Input 3 level control potentiometet varies the amplitude of the signal fed into the amplifier. Turn clockwise to increase and
counter-clockwise to decrease the signal level.

1. Multi Function Dipswitch
Understanding the functionality of the dipswitches is key to maximizing the versatility of the MA40G or MA60G.
SWITCH 1 - Input 2 Mute - When "ON", Input 2 signals will be muted if a signal is present on Input 1 (Refer to VOX Sensitivity
Control), or if a contact closure is present on the remote mute terminals.
SWITCH 2 - Input 3 Mute - When "ON", Input 3 signals will be muted upon a signal present on Input 1 (Refer to VOX Sensitivity
Control), or if a contact closure is present on the remote mute terminals.
SWITCH 3 - Phantom Power - When "ON", applies Phantom Power 24VDC to Input 1 terminals for condenser type microphones.
Note: Only use this feature if you are using condenser microphones, otherwise leave in the "OFF" position.
SWITCH 4 - Input 1 - When in the "MIC" position, Input 1 will accept microphone level signals; when in the
Input 1 will accept line level or telephone signals.
2. Input 1
Balanced mic or line level signals connect to the (+), (–), and (G) terminals. Refer to the chart on this page for the following setting.
Switch 4, labeled Input 1, must be set to the proper position for mic or line level. If you are connecting an unbalanced line level
input, tie (short) the (G) and (–) terminals together. If transformer isolation is required for Input 1, contact Atlas Sound for details.
3. Input 2
Input 2 consists of stereo summing inputs, suitable for connection to the output of CD/DVD players, etc.
