8-channel Microphone Preamplifier with A/D conversion

MP8d is an eight-channel class-A microphone preamplifier, which boasts Antelope Audio’s integrated world-class A/D conversion. Antelope’s converters are widely regarded for their naturally warm, yet sonically accurate sound signature.

This classically rich, yet modernly precise sound is accomplished thanks to Antelope’s Acoustically Focused Clocking jitter management algorithm and Oven-Controlled crystal oscillator, along with advanced analog and digital circuit board design, powered by a proprietary power supply.

…it’s a great sounding preamp and it’s so flexible with this app to control all the settings.”

MP 8d’s features



Generous analog connectivity in a device taking up just 1U space

The MP8d mic pres are combo XLR/TRS connectors, which accept both mic and line level signals. Hi-Z inputs are associated with channels 1 and 2, and are accessible via dedicated TRS connectors on the front panel. Inserts for connecting your favorite effects outboard gear are available on the rear panel.

A high-end headphone amp is accessible from the front panel to provide the convenience of integrated monitoring. The analog connectivity is accomplished with a D-Sub 25 connector directly outputting the mic signals at line level, making MP8d a perfect companion device for Antelope’s Orion32 and Zen Studio audio interfaces.

…even at maximum gain the preamp has a very low noise and sounds absolutely constant over the entire control range.”
