Aten AP9022-Channel Mic/LineExpansion

Aten AP902 — dual-channel mic/line pre-amp expansion card for ATEN AP DSP Power Amplifier series, adding two balanced/unbalanced inputs to the amplifier.

The Aten AP902 is a plug-in expansion card for the ATEN AP series DSP power amplifiers. It slots into the amplifier's expansion bay and adds two additional input channels capable of handling balanced or unbalanced audio signals from microphone level through to line level — making it straightforward to connect sources from mixers, media players, and other audio equipment directly to the amplifier without a separate preamp stage. Adjustable gain accommodates varying input signal strengths. The preamp circuitry is designed for a low noise floor and wide dynamic range, ensuring high-quality audio reproduction. Suitable for paging systems, lecture halls, and pro-level live sound applications. Euroblock connectors are included for secure cable connections.
