The XD88 Extreme Drive is designed to provide incredible flexibility, sonic excellence
and intuitive controls for loudspeaker and EQ management. The XD™ software with its
USB PC connectivity offers total control of your system with all the processing flexibility
necessary for both installation and live use. The XD88 is the next generation tool for
sound processing that is needed between the mixer and power amp.
Eight analog inputs and outputs make the XD88 one of the most powerful management
tools on the market today. The flexible matrix routing allows any of the 8 inputs to be
assigned to any of the 8 outputs, plus any multi-channel combination. As a primary
loudspeaker management system, the XD88 can control systems from 8 mono full-range
channels to stereo 4-way and everything in between. Other useful features include: 30
Band Graphic equalizers on each input with 60 instant access buttons for up/down of
each fader band. Each output has 4 parametric EQ's, high and low crossover filters
(Bessel, Butterworth, Linkwitz-Riley, 6-48dB/oct.), limiters with Threshold and Release,
speaker delays up to 456ms (500 feet) on each output, and a RTA real time analyzer with
a pink noise generator.
The XD88 provides a large 64x240 graphic display for easy programming. For remote
setting, use the easy to use USB PC interface – go to carvin.com/XD88 for the online
demonstration. Large memory capacity has enough storage to contain up to sixteen
complete 8x8 configurations or unlimited configurations on your PC allowing you to
keep settings for multiple loudspeakers, multi-room installs and line-arrays. Processing
offers extremely low latency, low noise with full 20-20Khz bandwidth from premium 24
BIT AD and DA converters.
The XD88 offers all the serious tools needed for a comprehensive loudspeaker
management system. Combined with 8 inputs/8 outputs, first-rate components, high order
AD DA converters, easy to use interface and a price that everyone can afford, the XD is a
