Introduction

Small, energy efficient, and affordable the Atlona Stereo/Mono Audio Amplifier fits the needs of most offices, classrooms and more. Unlike traditional A/B amplifiers the Class D audio amplifier is energy efficient and easily integrated behind a TV where space is limited.

Package Contents

• 1 x AT-PA100-G2

• 1 x Locking AC Adapter

• 1 x User Manual

Features

• AT-PA100-G2 is a class D amplifier which uses less energy, doesn’t require heat syncs or power

transformers, making it smaller than a class A/B amplifier

• Stereo, mono, and bridge audio speaker output connections available through captive screw

• Has a variable 3.5mm audio loop out for cascading to another AT-PA100-G2 or connecting to

other audio amplifiers

• 3 pin captive screw MIC input can support balanced and unbalanced signals (suppresses external

noise)

• Energy efficient standby mode only requires 4Ws of power. AT-PA100-G2 goes into standby

mode if an audio signal isn’t present

• Control through the panel buttons, an (optional) IR remote, and RS-232

• 3 position input switch:

48V phantom power - best for condenser MICs without battery power

MIC - Great for Dynamic MICs and battery powered condenser MICs

Line - Connect a Wireless MIC

• Volume, Bass, and Treble can be controlled through RS-232, IR, or panel buttons atlona.com
