Each channel of the HPA amplifier has an independent detented level control. When either of the potentiometers is turned down (left or fully counter clockwise) no signal will come out of the corresponding amp channel. When the potentiometer is turned up (right or fully clockwise) the amp will be set for maximum level. 2
Level Control Security Cover The HPA Series comes with a tamper-proof level control security cover. There are two screws that hold the security cover in place covering all level controls.
Ventilation HPA amplifiers have fan assist cooling that draws cool air in from the rear of the amp and exhausts the hot air out the front panel.
Status Indicators
A. Power – When AC mains power is applied to the amplifier and the AC Mains Power Switch is in the “ON” position this LED will illuminate blue indicating the amplifier is active and ready for use.
B. Standby – The Standby LED is a bi-color LED giving status of the amplifier power supply.
● Illuminated amber – The HPA Amplifier is in Energy Save Mode and is not ready for use. The rear panel remote activation control port has to be triggered by applying 5-24DC Voltage or shorting the Contact Closure (CC) and ground (GND) pins together to activate the amplifier to ready status.
Note: The HPA Amp is shipped with a shunt across the CC and GND contacts to activate the amp from Standby Mode. For the amplifier to be active or On, the Remote Turn On jumper must be in place and the amplifier switch must be in the “On” position. If the Standby LED is not illuminated and the front panel blue LED Power On is illuminated, the amplifier is active and ready to use. Refer to Remote Turn On for more information.
● Illuminated red – If the Standby LED is illuminating red, the AC Mains voltage applied to the HPA Amplifier is out of the safe operating range. The HPA Amplifier cannot be turned on until the AC Mains voltage is between 95-264V~. Refer to AC Mains Input for more information. If the Standby LED is not illuminated and the front panel blue LED Power On is illuminated, the amplifier is active and ready to use.
C. Temp – This LED represents the temperature condition of the amplifier. This LED will illuminate yellow once the thermal protection level of any of the amplifier channels or the power supply is reached causing the unit to power off. Note: Also refer to the Protect LED.
Front Panel
D. Ready – The Ready LED will illuminate green when the amplifier channels are stable and ready for use.
E. Signal – The Signal LED will illuminate green when the amplifier output signal produces at least 1-watt output.
F. Limit – The Limit LED will illuminate yellow when the maximum amplifier output level is achieved.

G. Protect – The Protect LED will illuminate red during one the following four conditions. No output will occur while this LED is illuminated. This condition will be reset after the protect condition has been corrected.

Shorted loudspeaker output.
Power Supply – If the amplifier exceeds its safe operating temperature, both output channels will be muted with both Protect LEDs illuminated to show the amp is in Protect Mode. The power supply will remain in protect Mode until the temperature returns to a safe operating temperature. Note: The Temp LED will also illuminate during this condition.
Current Overdrive, if the amplifier channels are driving too low of a loudspeaker load.
Failure of amp channel, if DC is present at the output the respective amp channel will go into protect mode.

Rear Panel

AC Mains Inpu t The HPA1204 and HPA2604 feature a global, wide range AC Mains power supply that operates from 100V-240V 50/60Hz power sources. The HPA1204 has an IEC-600320-C14 receptacle with retainer clip and is provided with a removable 1.8 meter 14 gauge NEMA 5-15 power cord. The HPA2604 has an IEC-600320-C20 receptacle with retainer clip and is provided with removable a 1.8 meter 12 gauge NEMA 5-20 power cord. Insert the IEC connector of the power cord into the IEC receptacle of the HPA Series amplifier making sure it is properly secured using the retainer clip. For non North American applications, refer to local electrical code requirements to select the proper mating power cord.
Amplifier Switch The amplifier switch turns the amplifier power supply from Standby mode to Active On mode. Up is “On” and down is “Off”. When on and AC is present the front panel Power LED will illuminate blue. Note: In order for the amplifier to go from Standby mode to Active mode, the amplifier switch must be in the Up (On) position, with either the Contact Closure in place or DC voltage (5-24VDC) present. The unit is always connected to the mains whether the switch is in the “On” or “Off” position.
AC Mains Breaker If the current drawn from the amplifier is greater than the rating of the AC Mains circuit breaker, the breaker will trip thus shutting the amplifier “Off.” Turn the amplifier levels to minimum and reset the breaker to the up position to reset the breaker.
Balanced Input Balanced line level signals connect to the (+) () and (G) terminals. Note: If connecting an unbalanced line level input, tie (short) the (G) and () terminals together.
Rear Panel
Amplifier Sensitivity Select & Parallel Mode Dip Switches Note: Switch 1 controls CH 1 and 2. Switch 3 controls CH 3 and 4. DP SW #1 – N/A = Not Applicable (Not Used) DP SW #2 – Parallel (Up) = Parallel mode internally combines Inputs 1 & 2 so only one connection is needed to send a signal to
Outputs 1 & 2. In parallel mode both amplifier output channels have separate level controls. DP SW #2 – Stereo (Down) = Stereo mode routes Input 1 to Output 1 and Input 2 to Output 2. DP SW #3 & #4 – Input Sensitivity, 0.775V, 1V, 32dB. Note: The same setting effects both channels
Amplifier Load Configuration Switches – IMPORTANT! Note: Switch 2 controls CH 1 and 2. Switch 4 controls CH 3 and 4. Note: Failure to choose the proper setting to the load applied may cause the amp to go into protect mode. DP SW #1 & #2 – Load Selection for CH 1 to be 4, 8, 70V, or 100V operation. DP SW #3 & #4 – Load Selection for CH 2 to be 4, 8, 70V, or 100V operation.

Rear Panel
Remote Turn ON Terminals The HPA amplifier can be turned on or activated from a remote location. Note: In order for the amplifier to go from Standby mode to Active mode, the amplifier switch must be in the Up (On) position, with either the Contact Closure in place or DC voltage (5-24VDC) present. One of these two must be active to turn on the amplifier’s power supply. If not, the Standby LED will illuminate amber. Factory shipping default includes a shunt applied across the Ground and CC terminals.
A. Contact Closure – Using a latching contact switch short the Ground and CC ports together. B. DC Voltage – Apply 5V – 24V DC to these ports.
Fault Reporting Terminals The HPA incorporates a fault reporting system to inform a system administrator if there is something wrong with the amplifier that needs to be attended to by a system technician. The ports are shorted together (NC, Normally Closed) when the amplifier is operating properly. The ports open up under the following conditions indicating there is an issue with the amplifier.
A. Shorted loudspeaker output.
B. Thermal, the temperature of the amplifier channel exceeds its safe operation.
C. Current Overdrive, if an amplifier channel is driving too low of a loudspeaker impedance.
D. Failure of an amp channel, if DC is present at the speaker output.

Rear Panel
Loudspeaker Connections The HPA Series amplifiers ship with a protective plate covering the loudspeaker terminal pins. This is required by safety approval agencies due to the high voltage levels produced. Remove this cover and install the Euro Block type connector to connect loudspeakers to the amplifier. Any connections to the Euro Block type connector are to be made by a qualified electrical technician. Note: Make sure the amplifier is unplugged from the AC mains source before starting the process due to the potential high voltage electrical shock. Discard the cover after it is removed and the loudspeaker terminal is installed. The removable Euro block connector is a 4 position, 7.62mm pitch design and is connected to the chassis by the 2 incorporated screws. It is recommended to use 12-gauge wire or larger for connection to the loudspeaker. The terminals can accept wire sizes of 6 – 18 gauge Class 2 wiring. Properly preparing the wire is critical to ensure a secure connection for safety and audio quality. First strip the wire back 0.250″ (5mm). We do not recommend tinning (soldering the wire). Insert the wire into the terminal block slot and secure by tightening the screws firmly. Failure to do so, could cause shock or damage the amplifier.
Accessory Card Slot The accessory card slot is for optional input cards such as the HPA-DAC4 (4 Channel Digital Audio Input Card). Contact AtlasIED for a full list of accessory cards. Note: Accessory card installation must be done by a qualified technician. 11. Air Inlet and Filters The rear air inlet has a removable filter grill that is connected to the mains chassis via magnets. Filters are to remain clean at all times to assure proper air flow for amplifier cooling.

Placement of the Amp

Turn off all equipment before making connections. Install the amplifier in a standard-width 19″ rack. It can be mounted above or below anything that does not generate excessive heat. Although the unit’s chassis is shielded against radio frequency and electromagnetic interference, extremely high fields of RF and EMI should be avoided.
Ventilation – The appliance should be situated so that its location or position does not interfere with proper ventilation. For example, the HPA amplifier should not be situated in a sealed cabinet or on a shelf with obstacles on it that may impede the flow of air through the ventilation openings. It is recommended that it be rack mounted into an equipment rack.
Heat – The HPA amplifier should be situated away from heat sources such as radiators, heat registers, stoves, or other appliances (including amplifiers) that produce excessive heat. Ambient temperatures should not exceed 95° F (35°C) when equipment is in use.

Cabling

The HPA amplifier can be used with either balanced or unbalanced sources, and the outputs can be used with either balanced or unbalanced loads, provided the proper cabling is used. A balanced line is defined as two-conductor shielded cable with the two center conductors carrying the same signal but of opposite polarity when referenced to ground.
An unbalanced line is generally a single-conductor shielded cable with the center conductor carrying the signal and the shield at ground potential.
Balanced Input – AtlasIED recommends using either 20 or 22-gauge two- conductor wire with shield for low level signals. Maintain the proper polarity, + to +, – to and shield to ground. Note: The ground center pin of the Phoenix connector is common for both channels.
Loudspeaker Outputs – Use 2 conductor unshielded wire of the appropriate gauge. Contact AtlasIED technical support at 1-800-8763333 with questions regarding wire gauge. The number of loudspeakers connected and their tap settings will be required for technical support to properly recommend wire.
Why choose 240V over 120V?
It is a good idea to provide an AC Mains voltage of 208-240V with a product that requires high amount of AC Mains current. Ohm’s law states that when voltage is high the current is lower. An amplifier that requires 30A of current at 120V only requires 15A of current at 240V.
One major advantage is the cost savings in the wire required to provide the current from the electrical panel to the receptacle. The minimum wire gauge needed to deliver 30A is 10AWG. For longer distances of 50ft – 150ft, 8AWG should be used. For 240V, only 15A is required and the wire gauge needed for that is only 14AWG. The cost between 14AWG & 8AWG is significant. Both methods only need 3 conductor. 208V – 240V in the USA requires a dual breaker. The cost of a dual breaker is similar in cost to a 120V 30A breaker.
A second advantage is with less current draw or demand there is less voltage sag in the AC Mains line. With less AC Mains voltage sag the amplifier will be able to produce more dynamic audio power when required.
Either 120V or 240V will work equally well, but keep in mind for a 120V service, using the proper wire gauge is very important to get the maximum performance out of the amplifier.

Connecting the HPA Amplifier to AC Mains

Do Not Do!

Never plug an HPA Series amplifier into a circuit without knowing what other products are connected to the same circuit.
Never plug an HPA Series amplifier into a power strip. Always connect directly to a dedicated circuit wall receptacle. Power strips are not designed to deliver high amounts of continuous or peak current.
Never plug an HPA Series amplifier into an extension cord.

Best Practices

Each HPA Series amplifier should have its own dedicated AC Mains line.
Consider using a 208V-240V AC mains power source.

HPA (HIGH POWER AMPS ) REQUIRE SPECIAL ATTENTION TO AC POWER

Connecting the HPA Amplifier to AC Mains

The HPA amplifier series allows for an optional HPA-DAC4 4-Channel DanteTM receiver card to be installed into the HPA amplifier. Contact AtlasIED for a list of accessory cards. Note: Accessory card installation must be done by a qualified technician.

Remove the HPA amplifier from the AC mains source.
Remove the two screws (M3 x 8mm Pan Head Black) holding the HPA accessory blank panel. Be careful and do not lose the screws.
Remove the ribbon cable from the cover plate PCB connector.
Connect the accessory card to the ribbon cable by carefully aligning the ribbon cable connector to the mating PCB connector. If aligned correctly the cable will mate easily.
Carefully guide the accessory card into the slot without forcing the PCB or cable.
After the card is inserted and the accessory panel is flush to the chassis, align the two screw holes and secure them together by using the M3 x 8mm screws.
