Dedicated for use with ATEN’s AP DSP Power Amplifier series, the AP902 is a plug-in expansion card providing the AP amplifiers with dual-channel inputs. It is capable of handling balanced / unbalanced audio signals ranging from mic level to line level, making it easier to combine the amplifiers with sources coming from mixers, media players, or other audio equipment utilized in pro-level live sound applications, enhancing audio system flexibility and versatility. The preamp’s circuitry is designed to lower the noise floor and improve the dynamic range to assure superior audio reproduction for the two extra microphone inputs it adds to the AP2 power amplifier series, making it a perfect solution for sound reinforcement applications such as paging systems and lecture halls.
