AtlasIED.

• Should any of the following irregularities occur during use, immediately switch off the power, disconnect the power cord from the

AC outlet and contact AtlasIED. Do not to attempt to continue operation with the product as this may cause fire or electric shock:

• Smoke or strange smell coming from the unit.

• If the product falls or the case is damaged.

• If water or any metallic objects falls into the product.

• If the power supply cord is damaged in any way.

• If the unit is malfunctioning.

• Do not insert or drop metallic objects or flammable materials into the ventilation holes of the product's cover, as this may result in

electric shock or fire.

• Do not place any containers with liquid or metallic objects on the top of the product. If any liquid spills into the unit, fire or electric

shock may result.

• Never operate this product or touch the power supply cord during an electrical storm, electric shock may result.

• Never exceed the power rating on the product when connecting equipment. Fire and/or property damage may result.

• Operate the product only with the voltage specified on the unit. Fire and/or electric shock may result if a higher voltage is used.

• Do not modify, kink, or cut the power cord. Do not place the power cord in close proximity to heaters and do not place heavy objects

on the power cord, including the product itself, doing so may result in fire or electrical shock.

• Ensure that the safety ground terminal is connected to a proper ground. Never connect the ground to a gas pipe as a catastrophic

disaster may result.

• Be sure the installation of the product is stable, avoid slanted surfaces as the product may fall and cause injury or property damage.

CAUTION - When Installing The Product

• Plugging in or unplugging the power cord with wet hands may result in electric shock.

• Never move the unit with the power cord plugged into the wall, as damage to the power cord may result.

• When unplugging the cord from the wall, grasp the plug, NOT the cord.

• Never install this product in humid or dusty locations, nor in direct sunlight, near sources of heat, or in areas where sooty smoke or

steam are present. Fire and electric shock may result.

• Keep all sides of the unit at least 31/2" away from objects that may obstruct air flow to prevent the unit's internal temperature rise.

CAUTION - When The Product Is In Use

• Never place heavy objects on the product, causing it to fall and/or break, resulting in personal injury and property damage. In

addition, the product itself may fall and cause injury and property damage.

• Contact AtlasIED for instructions on cleaning the inside of the unit. Large accumulations of dust inside the unit may result in heat

buildup and fire.

• Ensure that the power supply plug is securely plugged into the wall outlet. Never allow dust to accumulate on the power plug or

Multi-Impedance High Power Amplifiers

HPA Series

Introduction

Thank you for purchasing the AtlasIED HPA Series amplifier. The AtlasIED high power amplifier, “HPA” Series, is designed for use in both

commercial 70V/100V distributed systems and professional applications that require amplifiers to handle multiple impedance loads. The

HPA is compact and lightweight in comparison to other models delivering similar power levels. The HPA Series features Generation II

Class D Output topology that provides great efficiency with the sound quality of a Class AB amplifier. The power supply is a switch

mode, global auto sensing design that maintains a stable output during fluctuating power conditions. The power supply and output

stage collectively are designed to deliver exceptional dynamic high output voltage and current to virtually any loudspeaker load.

The HPA Series features front panel detente level controls with a security cover, remote turn on, balanced inputs, fault reporting and a

rear panel accessory card slot for an optional Dante™ 2-channel digital audio interface. HPA Series amplifiers feature a unique output

stage, low resistance direct coupled thermal transfer design that effectively maintains optimal temperature across all loads and output

levels. HPA Series amplifiers are also energy efficient and meet Energy Star standards, drawing only 1W of power in standby mode.

Whether the application is a large distributed constant voltage sound system or a high SPL sound reinforcement system, the AtlasIED

HPA Series is the answer for high power/cost effective amplification needs.

Key Features

• Two Channels

• 4Ω, 8Ω, & 70.7V Operation

• Balanced Inputs

• Dante™ Accessory Card Slot

• Fault Reporting

• Remote Turn On

• Stepped Attenuators with Security Cover

• Stereo or Parallel Operation Capability

• Auto Sensing 100V-240V~ AC Mains Power Supply

• Meets Energy Star Standards 1W Standby Mode

1. Channel Level Controls

Each channel of the HPA amplifier has an independent detente level control. When either of the potentiometers is turned down (left or

FCC - fully counter clockwise) no signal will come out of the corresponding amp channel. When the potentiometer is turned up (right or

FC - 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.

3. Air Exhaust

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.

4. 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 95V~ - 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.
