AA400PHD Owner’s Manual 400W Mixer Amplifier WARNING When The Device Is In Use • • • • • • • • • • To prevent electric shock, do not remove the product cover as there are high voltage components inside. Refer all servicing to Atlas Sound. Should any of the following irregularities occur during use, immediately switch off the power, disconnect the power cord from the AC outlet and contact Atlas Sound.
AA400PHD Owner’s Manual 400W Mixer Amplifier Introduction Congratulations and thank you for purchasing the Atlas Sound AA400PHD mixer amplifier. This new and innovative professional grade product has been designed from the ground up to include the important features that professional installation personnel require to meet or exceed their customer’s expectations.
AA400PHD Owner’s Manual 400W Mixer Amplifier Front Panel 4 3 7 2 5 8 6 1 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.
AA400PHD Owner’s Manual 400W Mixer Amplifier Front Panel 7. Input 1-6 Level The rotary control varies the amplitude of the signal fed to the amplifier input. Turn clockwise to increase and counter-clockwise to decrease the signal level. 8. Master Level The Master Level control will raise or lower all the input channels together. A good starting point for setting gain structure is to set the Master Level control at the 12:00 position, and then adjust the individual channels one at a time.
AA400PHD Owner’s Manual 400W Mixer Amplifier Rear Panel 5. 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.

Multi Function DIP Switch Input 4 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“.
AA400PHD Owner’s Manual 400W Mixer Amplifier Rear Panel 18. 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 Input volume controls. 19. Remote Input Select (RIS) Port Inputs 4, 5, & 6 can be remotely activated or selected.
AA400PHD Owner’s Manual 400W 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 system diagnostic test to assure the amplifier has the proper load applied. The proper load will assure a long lasting trouble free audio experience with your new AAPHD Series amplifier.
AA400PHD Owner’s Manual 400W Mixer Amplifier 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.
AA400PHD Owner’s Manual 400W Mixer Amplifier 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.
AA400PHD Owner’s Manual 400W Mixer Amplifier Connecting a Remote Level Control with Remote Input Select (RIS) Remote location of a level control can be accomplished via the Remote Level control port. You can control Input 2 or Inputs 4, 5, and 6. The AAPHD series remote level design is based on 10VDC return VCA type topology. Connections to a 10K pot require three conductors, with a minimum of 22 gauge wire, the 10K pot can be placed up to 1000ft away.
AA400PHD Owner’s Manual 400W Mixer Amplifier Connecting a Remote Level Control with Remote Input Select (RIS) Example 2 - Using a WPD-RISRL (Remote Input Select (RIS) with Remote Level) The AAPHD Series (Except AA30PHD) features a unique interface for remote selection of 3 inputs without running audio signal from the amplifier. This is ideal because the result is clean audio with no chance of picking up interference. It is intended to be used with the optional wall controller WPD-RISRL from Atlas Sound.
AA400PHD Owner’s Manual 400W Mixer Amplifier 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.
