Atlona AT-PA100-G2 Stereo/Mono Audio Amplifier

The Atlona AT-PA100-G2 is a stereo or mono amplifier that delivers clear, reliable sound in small to mid-size rooms where space and simplicity matter. It supplies either two channels at 20 watts each when driving 4-ohm speakers, or a single bridged channel at 40 watts with an 8-ohm load, giving integrators and end users the flexibility to match the amplifier to their exact loudspeaker setup.

Connection options cover nearly every common source. A balanced mic or line input includes selectable 48 V phantom power for condenser microphones, while unbalanced stereo inputs accept laptops, media players, or other consumer devices through RCA jacks or a 3.5 mm port. Independent gain controls let you balance speech and program material, and bass and treble trim help fine-tune the room response without extra processing gear.

Silent convection cooling removes the need for a fan, so the amplifier can sit on a shelf in a classroom, under a conference table, or inside a quiet living-room cabinet without adding background noise. The Class D output stage keeps power draw low and heat buildup minimal, which is especially important in tight mounting spaces.

System control is simple. Front-panel buttons offer quick access on site, and RS-232 or optional IR control allows integration with third-party processors and room control panels. A line-level output can feed an assistive-listening transmitter, overflow room, or recording device, making the AT-PA100-G2 a practical hub for small presentation systems.

Whether you are equipping a lecture hall that needs microphone support, a meeting room that hosts frequent laptop presentations, or a residential zone that calls for discreet amplification, this amplifier provides the power, connectivity, and control features required for professional, trouble-free audio.
