The ASI1462 and ASI1464 are analog microphone/line input modules intended for use in the Hono AVB/CobraNet Custom network interfaces. They contain eight microphone pre-amplifiers that operate at a 48kHz sample rate. The ASI1462 has fully balanced inputs with software selectable +48V phantom power. The ASI1464 is intended for aviation simulation applications and has unbalanced inputs with software selectable +12V phantom power.

Up to four ASI1462/4 modules may be used in one Hono Custom giving a maximum of 32 pre-amp inputs[5] , with up to 16 of those inputs able to be streamed over the CobraNet network at one time. AVB may use all 32 possible channels.

Powerful floating point DSP processing in the Hono Custom provides each microphone pre-amp with a 5- band parametric equalizer and compressor/limiter. A unique feature of the ASI1462/4 is its interchangeable I/O connector. A choice of 50pin Centronics (ASI1491), StudioHub+TM (ASI1492), Terminal Block (ASI1493), or 8 ¼” TRS inputs (ASI1494) allows the module to adapt to a variety of interconnection schemes with minimal custom wiring.
