- Overview
- Specification
Martin Audio DX0.4 is a digital PA system processor with 2 inputs and 4 outputs. It provides active-crossover, 10-band parametric EQ, input noise-gate, delay and limiting functions to optimise and protect a PA system.
Presets are provided for compatibility with Martin Audio's ADORN, CDD and BlacklineX ranges, also FlexPoint FP4, FP6 and FP8.
Professional 2-input, 4 output system processor for a wide range of system applications.
Comprehensive, sophisticated processing options including EQ, gate, delay and limiting to optimise and protect a system.
Fully assignable matrix routing of both inputs to any output with attenuation option on each routing node.
Two balanced XLR inputs with up to 12dB of gain, polarity invert, 600ms of delay, 10 band parametric EQ with a choice of 16 filter types individually selectable for each band.
Four balanced XLR outputs with 12dB of gain, polarity invert, 200ms delay, high and low pass filters with cut-off slopes from -6dB/oct to -48dB/oct using either Bessel, Butterworth or Linkwitz Riley filters. 8 band parametric EQ with up a choice of 16 filter types, Independent Program and Peak Limiters
Convenient front panel controls and LCD display with an intuitive menu system for programming or modifying settings. One press mute buttons for all inputs and outputs.
Front panel USB port for quick and easy PC connection.
Networking option using either Ethernet or RS485 for larger systems.
Output channel preset import function to quickly and easily compile a system to suit any application utilising a library of Martin Audio product channel presets.
Six segment LED metering for input and output levels and limiter operation.
32 User Presets to store system configurations.
3-level customisable user modes with individual password protection.
Universal switch mode mains PSU accepts 90 to 240V, 50/60Hz.
Compact 1 rack unit design.
