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 TRS inputs (ASI1494) allows the module to adapt to a variety of interconnection schemes with minimal custom wiring.Main Features:Eight microphone pre-amplifiers/line inputsASI1462: Low noise balanced microphone input with selectable 48V phantom supplyASI1464: Low noise un-balanced microphone input with selectable 12V phantom supply-60 to +26dBu software controlled input level-98dB THD+N, 105dB DNR, -120dBu EINCompressor/Limiter5 band parametric equalizerInterchangeable Module Connectors with choice of 50pin Centronics connector, Terminal Block, or 8 TRS inputsUp to four modules can be used in one Hono CustomSpecifications:Type: BalancedInput Level: -60 to +26dBu in 1dB incrementsInput Impedance: 10K ohmsPhantom Power [4]: ASI1462: 12V @ 10mA max per input, software selectable on each input; on and offEIN [3]: 120dBuDynamic Range[1]: >105dBTHD+N [2]: < -98dBA/D converter: 24bit Over samplingSample Rates: 48 kHzFrequency Response: 20Hz to 20kHz +/-0.25dBSIGNAL PROCESSING:Compressor/Limiter[5]: Attack, Decay, Input Threshold, Makeup gain.Equalizer[5]: 5 band, parametricSAMPLE RATE CLOCK:Internal: 48kHzCONNECTOR MODULES:ASI1491: 50 pin CentronicsASI1492: StudioHub compatible RJ-45 jacksASI1493: 5 position 3.81mm pluggable terminal block (8 per module)ASI1494: 8 TRS inputsGENERAL:Bus: AudioScience Hono Custom series module busDimensions: (Without Module Connector) 5.5" x 3.25" x 0.6" (140mm x 83mm x 15mm)Weight: 8 oz (227g) maxOperating Temperature: 0C to 70CPower Requirements: +5V @ 500mA
