1. Power Switch
This push switch (On/Off) supplies power to the mixer amplifier.
2. Power Indicator
This LED illuminates Blue when the power switch is turned On.
3. Signal Indicator
When the signal LED illuminates Green, input signals are connected to the amplifier. The Signal LED is PRE the input level controls.
4. Peak Indicator
The AAPHD Series amplifier has an input signal peak limiter located between the preamp mixer stage and the power amplifier stage.
This input signal peak limiter is designed to prevent the amplifier from being over driven by excess input signals that may cause
damage to the amplifier. If the amplifier preamp stage senses excessive input signal, the peak limiter will engage reducing the signal
and the Peak LED will illuminate Red. An occasional flash of the LED is OK. If ON steady state; turn the associated level control down
until the Peak LED turns OFF. It may be necessary to reduce the signal level at the input of the amplifier.
5. Limit Indicator
This LED serves two functions:
A. PHD Test Circuit Load Fault Indicator - When testing the system using the PHD feature for proper wiring and amplifier
loading, this LED will illuminate Yellow if a fault is sensed in the audio speaker system. See “Using the PHD Load Impedance
Testing System.” Note: For 70V distributed systems only.
B. Excessive Current Draw Limit Indicator - Will illuminate Yellow when the amplifier is consuming excessive current. At that
point, a current limiting circuit is activated, reducing the output power to prevent damage to the amplifier. The most likely
cause for the fault is an incorrect load impedance connected to the amplifier. The LED should not come on if a proper load is
applied. If the Limit LED is illuminating, use the PHD Load Impedance test explained in the manual to help troubleshoot the
cause of the problem. Note: An occasional LED flash is okay. When LED is ON audible distortion may be heard at the speakers.
6. PHD Switch
The AAPHD Series features a patent pending Amplifier Diagnostic System. The PHD (Push Here Diagnostic) is simple to use and
very effective in testing the speaker wiring and load impedances on 70V speaker systems to assure the proper load is applied to the
amplifier. Please read the section on “Using the PHD Feature” before activating the circuit. To activate the PHD circuit a small tool with
a point will be required to access the momentary switch through the hole on the front panel. See “Using the PHD Mixer Amplifier Load
Impedance Testing System.”

1. Bass Control
Normally set at the 12:00 position, rotating clockwise will increase (boost) bass frequencies to a maximum of +6dB at 100Hz. Rotating
counter-clockwise from the 12:00 position will decrease (cut) bass frequencies to a maximum of -6dB at 100Hz.
2. Treble Control
Normally set at the 12:00 position, rotating clockwise will increase (boost) treble frequencies by +6dB at 10kHz. Rotating
counter-clockwise from the 12:00 position will decrease (cut) treble frequencies by -6dB at 10kHz.
3. Input 1
Balanced Microphone or Line level signals connect to the (+), (-), and (G) terminals. To select between Mic or Line input levels, refer
to the DIP switch chart on the rear of the amplifier for feature assignment. If connecting an unbalanced line level input, tie (short) the
(G) and (-) terminals together for negative or ground connection and the positive or (+) signal to the (+) terminal on the amplifier input.
If the input is used in Mic mode, Phantom power for condenser type microphones is available in the DIP switch settings on the rear
panel. Input 1 level control located on the front panel adjusts the levels to the amplifier mix.
4. Input 2
Input 2 consists of RCA stereo summing inputs, suitable for connection to the output of CD/DVD players, etc.
5. Input 3
Input 3 consists of RCA stereo summing inputs, suitable for connection to the output of CD/DVD players, etc.
6. Remote Mute Connector
Shorting the Remote Mute terminals will mute the inputs that are assigned to receive the mute command. When an input is set to
Mute Receive via the corresponding DIP switch, the input associated to the switch will be muted when terminals (G) and (M) are
shorted together. This connection is usually done via remote switch on a microphone.

7. VOX Mute Sensitivity Control
Input 1 signal can be used to trigger or activate a mute command. When an input is set to Mute Receive via the corresponding DIP
switch, the input associated to the switch will be muted when a signal is applied to Input 1. The VOX Mute Sensitivity Control adjusts
how sensitive the mute circuitry from 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. Calibration of this control in conjunction with the microphone to be
used is very important to assure the proper amount of signal from the mic is enough to trigger the mute circuits. If it is not calibrated
properly, the mute may not be triggered when a weak voice vs a strong voice uses the mic.
8. Zone 2 Output Port
This terminal provides a 600Ω unbalanced output that is typically connected to a PBX music on hold port, also known as MOH. Inputs
are assigned to the Zone 2 bus via switch associated with the input. Note: 10kΩ output impedance is available via the internal shunt
selection.
9. Zone 2 Output Level Control
This control will vary the level at the Zone 2 output terminals. Fully counter-clockwise (0) is Off, fully clockwise (10) is the maximum
output level. The Zone 2 level control is PRE Inputs 1, 2, 3 and 4 volume controls.
10. Multi Function DIP switch
Understanding the functionality of the DIP switches is key to maximizing the versatility of the AAPHD Series. When a switch is in the
up position, the function is “OFF or assigned to the feature stated”; when a switch is in the down position, the function is “ON or
assigned to the feature stated “.

30W Mixer Amplifier
Using the PHD Mixer Amplifier Diagnostic System
The AAPHD Series features a patent pending Amplifier Self Diagnostic System. The PHD (Push Here Diagnostic) is simple to use and
is very effective running a 70V distributed system diagnostic test to assure the amplifier has the proper load applied. The proper load
will assure you a long lasting trouble free audio experience with your new AAPHD Series amplifier. Many amplifiers fail because an
incorrect load is applied to the amplifier. This is especially true when using the amplifier in a 25V or 70V distributed audio speaker
system. There are a few common failure points that can occur during system installation that are listed below.
Common Amplifier Failure Conditions, also see “How to Trouble Shoot Your Speaker System if the Limit LED is Illuminating”.
1. A short in the speaker wiring.
2. Improper load selection or power tap setting on 70V speaker systems. It is very common when using many speakers to
have one of the speakers tapped accidently at 8Ω. This error will definitely be very hard on a 70V amp and in most
cases cause the amp to fail within a few days. This kind of error is easy to make, time consuming to find and costly to fix.
3. Too many speakers attached or the wrong power taps are selected. If a 100 watt amp is used in a 70V system and it has ten
speakers all tapped at 10W, but three of the speakers are accidently tapped at 30W, that comes up to 160W of power
required to drive the system properly. While it may work at low levels, as soon as the system needs to be louder the
amp will be strained and could fail over time.
Most amplifier failures are caused by improper installation on the speaker side. There are two known ways to test the speaker system
after everything is installed.
A. Measure the speaker system using a true audio frequency impedance meter. These are the best way to see if your speaker
system is wired correctly for the amplifier.
B. Run the PHD Self Diagnostic test.
Running a Self-Diagnostic Test using the PHD Feature
Step 1 - Install the AAPHD Mixer amplifier, connect the input signals. Turn all levels to minimum. Do not attach the speaker system to
the amp at this point.
Step 2 - Install the 70V distributed speaker system per the design, double check speaker tap settings. The total power for all the
speakers should NOT exceed the maximum power rating of the amplifier installed.
Step 3 - Connect the speaker system to the amplifier. Pay special attention when connecting the speaker leads to the proper terminals
on the amplifier. Note: All speaker power taps must be on a 70V setting.
Step 4 - Turn the amplifier On.
Step 5 - Before starting the system Diagnostic test. Make sure no people are present or near the speakers during the diagnostic test
without taking proper precautions. A 1 watt test tone will be present at each speaker. The audible SPL level will be based on the power
tap setting at each speaker and sensitivity specification of the speaker. The audible SPL level may be alarming to some people. Wear
proper hearing protection before starting the test.
Step 6 - Activate the PHD circuit by inserting a small, pointed tool through the hole on the front panel labeled PHD. Press and hold
the momentary switch for 5 seconds, then release. A test tone will be audible through the speaker system. If the Limit LED does not
illuminate Yellow, the system is properly set up and no errors in the system were found. Continue the installation.
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.

How To Trouble Shoot Your Speaker System If The Limit LED Is Illuminating
LED OFF
TEST
PASS
The Limit LED should never be constantly illuminated or damage may occur to the amplifier or sound system. If the Limit LED comes
on steadily during use or during the PHD test there are a few common fault conditions to check if using a 70V distributed audio system.
A. Check each speaker setting to make sure it is not set to a 4, 8 or 16 ohm setting. If one speaker is set to one of these
settings it will cause a fault condition. A simple and quick way to test this besides visually looking at each speaker is to have a
second technician walk the area where the speakers are installed while the PHD test is applied and listen for a speaker that is
audibly louder that the other speakers. The louder speaker most likely will be incorrectly tapped and the cause of the fault.
Note: Always take proper hearing precautions.
B. Check each speaker to be sure the load tap is set to the correct power setting. The total power tap selected of all the speakers
combined should not exceed the amplifier’s maximum power rating or a fault may occur.

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.
Note: For more detailed examples on how to trouble shoot PHD amplifier faults, please visit www.atlassound.com
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.
