Frequently Asked Questions - HPA2602 Atlas Sound

How do I configure the amplifier for bridged operation?

Set dip switches #3 and #4 to the UP position (BRG). Apply a mono input to Input 1. The load must be connected across the positive terminals of both output channels. The Bridge Mode indicator (yellow LED) on the rear panel will illuminate.

What is the standby mode and how do I activate the amplifier?

Standby mode (amber LED) saves power. To activate, ensure the front panel switch is ON and either a jumper is placed across the CC and GND terminals (default) or apply 5-24V DC to the remote turn-on port. The amplifier is ready when the blue Power LED illuminates.

Can I connect unbalanced input signals?

Yes. For unbalanced signals, tie (short) the (G) and (−) terminals together on the balanced input connector. Use a shielded single-conductor cable with the shield connected to ground.

What do the front panel status LEDs indicate?

Power: blue when ON. Standby: amber (energy save) or red (AC mains out of range). Temp: yellow near thermal limit. Ready: green when stable. Signal: green at 1W output. Limit: yellow at maximum output. Protect: red indicates fault (short, overtemp, etc.).

How do I reset the AC mains breaker?

If the breaker trips, turn the amplifier level controls to minimum, then push the breaker switch to the UP (reset) position. If it trips again, check for a short circuit or excessive load.

What type of AC power is recommended for the HPA2602?

Use a dedicated circuit. For 120V operation, a 20A circuit is recommended. For 230V, a 10A circuit. Avoid power strips. The amplifier auto-senses voltage between 88-135V~ and 180-264V~.

How do I clean the air intake filter?

The rear filter is held by magnets. Remove the filter grill, wash the filter with mild detergent and water, let it dry completely, then reinstall. Keep filters clean to ensure proper cooling.

Can I install a Dante card myself?

Installation must be done by a qualified technician. Disconnect AC power, remove the blank panel, connect the ribbon cable to the card, guide the card into the slot, and secure with the screws.

What is the fault reporting feature?

The fault report terminals are NC (normally closed) when the amplifier is operating correctly. They open under fault conditions (short, overtemp, overcurrent, DC output). Connect these to an external monitoring system.

What is the maximum speaker wire gauge I can use?

The Euro block connectors accept wire sizes from 6 to 18 gauge (Class 3). For best performance, use 12-gauge wire or lower. Strip 5mm of insulation and tighten screws firmly.

1. AC Mains Input

The HPA amplifier incorporates an auto sensing wide range AC mains power supply. The amplifier will operate if the AC mains voltage is between 88V\~ - 135V\~ or 180V\~ - 264V\~. The HPA amplifiers will detect the AC mains voltage and automatically switch the power supply between 120V\~ or 240V\~ operation. If the AC mains is not within the AC Mains voltage requirement the amplifier will not turn on. The Standby LED will illuminate red as an indicator.

A. HPA2602 - A 20A 16A/250V\~ IEC-60320-C20 receptacle with a retainer clamp is provided for ease of power cord change out to meet global standards. A 3m 12-gauge power cord with a USA NEMA5-20 male plug is supplied in the carton. Insert the IEC power cord into the receptacle making sure it is securely placed with the retainer clamp. AtlasIED recommends for 88V\~ - 135V\~ operation, a 19.5A AC mains service, and for 180V\~ - 264V\~ operation, a 10A AC mains service.
B. HPA4202 - Ships with a captive 3m 10-gauge cord with a removable Locking 125V 30A NEMA L5-30P plug. Due to the various types of global AC Mains receptacles, AtlasIED requests that a certified electrician select the plug type that meets the requirement. AtlasIED recommends for 88V\~ - 135V\~ operation, a 30A AC mains service, and for 180V\~ - 264V\~ operation, a 15A AC mains service. Refer to "Wiring the HPA4202 Amplifier AC Mains" for more information.

2. 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 present.

3. 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.

4. 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.

9. Loudspeaker Connections

The HPA amplifiers ship with a protective plate covering the loudspeaker terminal pins. This is required by safety approval agencies due to high voltage 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 power source before starting the process because of the potential high voltage electrical risks involved. Discard the cover after it is removed and the loudspeaker terminal is installed. The removable Euro block connector is a 4 position, 10.16mm pitch and is connected to the chassis by 2 incorporated screws. It is recommended to use 12-gauge wire or lower for connection to the loudspeaker. The terminals can accept wire sizes of 6 - 18 gauge Class 3. Properly preparing the wire is critical to ensure a secure connection for safety and audio quality. First strip the wire back 0.250^t (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.

10. Accessory Card Slot

The accessory card slot is for optional input cards such as the HPA-DAC2 (2 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 113°F (45°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 - Use 2 conductor w/shield for low level signals of 20-22 gauge is best. 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. If you are unsure about this, contact AtlasIED Tech Support at 1-800-876-3333. Make sure you know how many loudspeakers you need and what tap value you intend to use.

Why choose 230V 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. This configuration has advantages over a supply voltage of 120V. Ohms law states that when voltage is high the current is lower. At 120V, the HPA4202 requires 30A of current and at 230V requires 15A of current.

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 230V, 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.

The 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 230V 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.

Wiring the HPA4202 Amplifier AC Mains

The HPA amplifier can be connected to an AC mains source of 120V\~60Hz and 230V\~50Hz. The HPA4202 delivers a very large amount of audio amplification. To achieve this high output power, the amplifier needs a stable AC Mains power source that can deliver enough AC Voltage & AC Current to allow the amplifier to produce the audio power required. In the world market, there are many different AC mains sockets available and in many places they are limited to the specific type that can be used dictated by the local code requirements. It would be difficult to provide an AC Mains power plug that would mate with all AC mains receptacles. Many lower power products use the international IEC socket and power cord that allow the installer to use the appropriate power cords to mate with the installations AC Mains receptacle. The HPA4202 exceeds the current rating of the 15A or 20A IEC power cord and ships with a removable Locking 125V 30A NEMA L5-30P AC mains plug attached to the power cord. If the amplifier needs to be configured for 208V - 240V North America or 230V for Europe, the AC 125V 30A AC plug can be removed and replaced by the appropriate AC plug as defined below. Note: The removal of the AC plug must be done by a approved electrician. We allow the installer to choose the connectivity method that meets the AC Mains installation requirements. Connection to the mains shall be done in accordance with the local codes and/or national requirements of the countries where the unit is sold and to be used.

Wiring the HPA4202 Amplifier AC Mains

For North America 208V-240V Only

AtlasIED recommends using a 208V - 240V power source. In most applications that require a high current demand, it is usually less expensive to pre wire a facility for 220V than 120V because of the reduced wire gauge requirements. In addition, there is far less potential for AC line voltage sag with 220V circuits than 120V circuits. Reduced line sag allows the amplifier to deliver the maximum audio amplification possible. The HPA4202 requires 3 conductors for both 120V or 220V circuits. The HPA4202 features auto sensing circuitry for either 120V or 220V operation, with no rewiring or switches to select. When selecting the AC plug there are many options available. The HPA4202 requires a 15A circuit for 220V. AtlasIED suggests using a locking 15 Amp, 250VAC Voltage, NEMA Configuration: L6-15P, 2 pole plug, or a 20 Amp, 250VAC Voltage, NEMA Configuration: L6-20P, 2 pole plug. Either 15A or 20A 250V models will work. There are many other 220V AC connections available to select from. Note: The HPA4202 ships with a removable 125V 30A NEMA L5-30P plug on the power cord. Replacement of the plug must be done by a electrician or technician.

Wiring for 208V\~240V 60Hz AC Main Requires a minimum of 15A AC Mains Breaker

Power Cord Wiring:

• Green / Yellow - Earth Ground
- White - L1 Load / Hot
- Black - L2 Load / Hot

For Europe - Wiring for 230V\~ 50Hz AC Main Requires a 15A AC Mains Breaker

Power Cord Wiring of the HPA4202:

• Green / Yellow - Earth Ground

Connecting the HPA Amplifier to AC Mains - Best Practices

Do Not Do!

1. Never plug an amplifier into a circuit without knowing what other products are connected to the same circuit.
2. Never plug an HPA2602 or HPA4202 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.
3. Never plug a high power amplifier into a extension cord.

Best Practices

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

HPA (HIGH POWER AMPS) REQUIRE SPECIAL ATTENTION TO AC POWER
Know the type of outlet you are going to use and never use an adapter!

HPA Amplifier Dante™ Accessory Card Installation

The HPA amplifier series allows for an optional HPA-DAC2 2-Channel Dante™ receiver card to be installed into the HPA amplifier. Contact AtlasLED for a list of accessory cards. Note: Accessory card installation must be done by a qualified technician.

1. Remove the HPA amplifier from the AC mains source.
2. Remove the two screws (M3 x 8mm Pan Head Black) holding the HPA accessory blank panel. Be careful and do not lose the screws.
3. Remove the ribbon cable from the cover plate PCB connector.
4. 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.
5. Carefully guide the accessory card into the slot without forcing the PCB or cable.
6. 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.
