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
Features
• 1 x AT-PA100-G2
• 1 x AC Adapter
• 1 x User Manual
• 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 0.4Ws 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
