PreSonus DigiMax D8 Microphone Pre-Amp

The DigiMax D8 provides eight high-quality custom-designed, high-voltage, discrete, XMAX Class A microphone preamplifiers that are suitable for use with all types of microphones. 

The net result of the XMAX preamp design is high headroom, low noise, wide dynamic range, extended frequency response, and—most important—musicality and transparency, with smooth highs, solid deep lows, and everything in between.

With its eight XLR mic inputs and eight ¼” balanced, direct channel outputs, you can route each channel’s signal independently. This makes the DigiMax D8 a premium front end for virtually any system. And thanks to its eight-channel, 24-bit ADAT Lightpipe output (which operates at 44.1 or 48 kHz), the DigiMax D8 provides an excellent front end for Lightpipe-equipped digital-audio devices.
