AA400PHD
400W Mixer Amplifier
1601 Jack McKay Blvd. • Ennis, Texas 75119 U.S.A.
Telephone: 800.876.3333 • Fax: 800.765.3435
Wiring the AAPHD Series Amplifier
• Mic/Line Input - Use 2 conductor w/ shield for low level signals; 20-22 gauge stranded wire is best. Maintain the proper
polarity, + to +, – to – , and shield to ground.
• Unbalanced Inputs and Outputs - Pre-made RCA cables can be purchased from Atlas Sound to simplify interconnection to
external devices.
• Zone 2 Out - Use 2 conductor, 20-22 gauge, shielded is best. Terminate the shield at the input to the device if possible.
• Speaker Outputs - The AAPHD Series is rated for Class 2 wiring, meaning it is not required to run the wire in conduit. Use
Class 2 rated wire, 2 conductor unshielded wire of the appropriate gauge. Contact Atlas Sound Tech Support at 1-800-876-3333
for more information on proper wire gauge selection.
Level Control Security Cover Option
In order to prevent unauthorized operation of the AAPHD Series amplifiers, optional security covers are available which take the place
of the front panel knobs. After the amp 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 AAVCC-5, available in quantities of 5.
