Detailed review of the outstanding features and characteristics of the Martin Audio DX0.4 Controller

Martin Audio DX0.4 Not only is it a simple Digital Signal Processor (DSP), but it is also considered the “central brain” in professional audio systems. This product is designed to optimize performance, protect equipment and provide flexibility in system configuration.

Powerful and flexible signal processing capabilities

Important highlights of Martin Audio DX0.4 is a sophisticated signal processing capability with a 2-input configuration and 4 balanced XLR outputs. Each input channel is equipped with a 10-band parametric EQ, supporting up to 14 different filter types (high-shelf, low-shelf, notch, band-pass, peak, all-pass…).

This allows the sound engineer to adjust the frequency range extremely precisely, optimizing the sound quality for each space and performance style. In addition, the delay feature of up to 600 ms for input and 200 ms for output helps to synchronize the signal perfectly in multi-speaker systems, avoiding phase deviation or delay. This is a clear advantage when deployed on large stages or rooms with many speaker areas.

Professional filtering with Bessel, Butterworth and Linkwitz-Riley algorithms

One of the premium features of Martin Audio DX0.4 Controller is a crossover filter system that integrates three famous algorithms: Bessel, Butterworth and Linkwitz-Riley.

Butterworth provides smooth response, Linkwitz-Riley provides linear phase, and Bessel optimizes group delay. These filters support slopes from –6 dB to –48 dB/octave, providing precise control of the frequency range between the bass, mid, and treble speakers. This allows the entire speaker system to work together harmoniously, avoiding frequency overlap and ensuring smooth, stable sound quality even when operating at high power levels.

Comprehensive speaker protection solution with smart limiter

Besides improving sound quality, Martin Audio DX0.4 Also integrates superior speaker protection mechanism. Peak limiter and program limiter system help prevent overload, protecting the speaker membrane when the signal suddenly spikes.

In addition, each output channel can adjust the gain ±12 dB, reverse polarity and add delay, allowing for calibration to suit many real-life situations. Thanks to this active protection feature, DX0.4 helps prolong the life of the device, minimize the risk of damage and save maintenance costs for users.

Compact design but rich in applications

Despite possessing many advanced technologies, Martin Audio DX0.4 still maintains a compact design of only 1U rackmount, weighs about 3,5 kg, easy to install in any rack cabinet. The front is equipped with a sharp LCD screen and an intuitive control button system, helping to operate quickly even for novice engineers.

Additionally, separate mute buttons for each input and output allow the required channel to be quickly muted without affecting the entire system – an extremely useful convenience when troubleshooting or fine-tuning live during a performance.

Diverse connectivity and smart management

Martin Audio DX0.4 Supports multiple connectivity options, from front-panel USB for quick PC programming, to Ethernet and RS-485 for remote management in large-scale audio systems. The device also allows storage of 32 user presets, plus a library of genuine speaker presets. Martin audio, making configuration simpler and more accurate.

In addition, the security system with 3 user levels and passwords ensures safe management, especially suitable when the device is used in an environment with many operating engineers.
