The Audient ASP800 is an 8-channel microphone preamplifier and ADC featuring Audient's Class-A console preamp design, Burr Brown 118 dB converters, and two retro channels with HMX (harmonic saturation) and IRON (transformer emulation) tone-shaping controls. Two front-panel JFET instrument inputs provide high-impedance connectivity for guitars, basses, and keyboards. Preamps and Tone Shaping Mic preamps: 8 Class-A Audient console preamps HMX: Adds harmonic content inspired by tube saturation (channels 1-2) IRON: Emulates transformer-driven warmth and compression (channels 1-2) Instrument inputs: 2 front-panel discrete JFET DI (1 M-ohm impedance) Phantom power: +48V switchable per channel Pad: -15 dB, front-panel switchable per channel Conversion and Digital Output Digital output: ADAT (8 channels, SMUX at 88.2/96 kHz) Word clock input: BNC with switchable 75-ohm termination Analog outputs: 8 balanced line outputs on DB25 Specifications Mic gain: 0 to 70 dB ADC dynamic range: 118 dB (Burr Brown) Sample rates: 44.1 to 96 kHz Mic EIN: < -127.0 dBu THD+N: < 0.003% at 0 dBu Max input level: +20 dBu (+35 dBu with pad) Power: Internal linear PSU, fanless (100/110/220/230V switchable) Form factor: 1U rackmount, all-metal enclosure Dimensions: 482 x 286.5 x 44 mm (19.0 x 11.3 x 1.7") Weight: 4.5 kg (9.9 lb) In the Box Audient ASP800 IEC mains power cable Quick Start Guide
