Description
Intended for professional recording studios, the Audient ASP880 offers eight Class-A microphone preamplifiers from the company’s consoles designed by David Dearden via XLR/TRS combo connectors as well as Burr Brown analogue to digital conversion in an all-metal 1RU 19″ rackmountable enclosure. It also features a pair of front panel Class-A JFET 1/4″ DI instrument inputs for recording guitars, keyboards, drum machines, and more.
Each channel features a selectable +48V phantom power button, a selectable pad, a selectable polarity reverse switch, a variable high-pass filter, and a switch for inserting a signal processor between the preamplifier and A/D convertor. A front-panel button allows you to select and lock the sample rate of the convertor at 44.1, 48, 88.2, or 96 kHz. Digital outputs are provided by rear-panel ADAT, AES, and SPDIF connections. A word-clock input is also included.
