1. Balanced Line Input
Balanced line level signals connect to the (+), (–), and (G) terminals. 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. Note: The Balanced
Line Input and the Unbalanced RCA Inputs are electrically isolated from each other and can be used at the same time.
2. Unbalanced Stereo RCA Input
Input 2 consists of stereo summing inputs, suitable for connection to the output of CD/DVD players, etc. Note: The Balanced Line
Input and the Unbalanced RCA Inputs are electrically isolated from each other and can be used at the same time.
3. 70.7V / 100V Speaker Output
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. It is recommended to use class 3 rated,
16-gauge wire or higher for speaker wiring.
4. Global IEC AC Mains Power Receptacle
The PA Models support global power sources from 100V-240V 50/60Hz. The package contains a cord that has an international IED
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.
Wiring the PA40G / PA60G
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.
It is recommended to use class 3 rated, 16-gauge wire or higher for speaker wiring.
Balanced 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 Input - Pre-made RCA cables can be purchased from vendors to simplify interconnection to external devices.
