The DigiMax D8 is an 8 channel preamplifier featuring 8 award-winning class A XMAX mic preamps with 24-bit ADAT digital output. All eight preamps include variable trim control, 48V phantom power, ultra-fast acting LED metering and 20 dB pad. In addition, 2 instrument inputs are located on the front panel for direct Hi-Z instrument input. Balanced TRS direct analog outputs are located on the rear panel for routing and flexibility. The DigiMax D8 also includes word clock sync input for ultra-low jitter and robust synchronization.

The DigiMax D8 is the perfect solution to add eight professional microphone preamplifiers to any digital recording system with ADAT optical lightpipe expansion capability including Digidesign’s HD and 003 systems, RME, YAMAHA, Alesis, Mackie, and many others.
