Martin Audio DX0.4 Networked Loudspeaker Management System 2 IN / 4 OUT

Description

The Martin Audio DX0.4 is a compact yet powerful 2-in/4-out digital system processor designed to optimize and protect PA systems in a wide range of live and installed sound applications. With comprehensive processing tools including active crossover, noise gate, delay, parametric EQ, and independent limiters, the DX0.4 provides precise control over system performance and tonal balance. It supports full matrix routing with individual attenuation per node, and presets are included for seamless integration with Martin Audio’s ADORN, CDD, BlacklineX, and FlexPoint FP4, FP6, and FP8 loudspeakers.

Each of the two balanced XLR inputs offers up to 12 dB gain, 600 ms delay, polarity inversion, and a 10-band parametric EQ with 16 selectable filter types. The four balanced XLR outputs provide full signal shaping with 12 dB gain, 200 ms delay, high/low pass filters with selectable slopes (Bessel, Butterworth, Linkwitz-Riley up to 48 dB/octave), 8-band parametric EQ, and dual-stage program and peak limiting. Front panel access is intuitive via an LCD screen and rotary control, with quick-mute buttons, metering, and a USB port for PC connectivity. The DX0.4 also supports Ethernet and RS485 networking for system-wide control in larger setups.

With 32 user presets, customizable user modes with password protection, and a universal 90–240V PSU in a single rack unit, the DX0.4 is a powerful, flexible processing engine tailored to modern audio system needs.
