How To Trouble Shoot Your Speaker System If The Limit LED Is Illuminating
C. If the first two check points are OK, there is probably a short in the wiring of the speaker system. Common causes include
staples through the wire and the wire cut by metal conduit causing a short to ground.
D. Excessive Current Draw - The Limit LED will illuminate Yellow when the amplifier is consuming excessive current. The most
likely cause for the fault is an incorrect load impedance connected to the amplifier. The LED should not steadily illuminate if a
proper load is applied. Note: An occasional LED flash is okay during standard operation. When LED is ON audible distortion
may be heard at the speakers.
E. After finding and correcting the issue, perform the PHD test until the Limit indicator is no longer illuminating.
Note: During the initial start of the diagnostic test, the Limit indicator may flash Yellow for a few seconds until an accurate
diagnostic reading has been completed, continue to hold the PHD switch in for 5 seconds to assure the test is complete. After
5 seconds and the Limit indicator is illuminating Yellow steadily, stop and read the section "How to Trouble Shoot Your Speaker
System If the Limit LED is Illuminating.

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.
