Audient ASP880

Audient ASP880 - microphone preamplifier and ADC with 8 channels. It is equipped with Audient Class A preamplifiers, conversion technology with Burr Brown converters, and a feature that includes variable impedance to accommodate different types of microphones, including ribbon types, and variable high-pass filters to eliminate unwanted low frequencies, all in a 1U rack unit.

In addition to the 8 microphone and line inputs, it also offers 2 JFET DI inputs, dedicated for electric guitars and bass. It can be used as an 8-channel microphone preamplifier, and the converters can be used in parallel in stand-alone mode, selectable via the A-D button.

Solid construction in a metal chassis with aluminium knobs.
