The Martin Audio DX4.0 is an advanced loudspeaker controller and system matrix with four input and eight output channels. Class-leading sonic performance is achieved by state-of-the-art audio converters and DSP algorithms, with a 96kHz sampling frequency delivering a nominally flat response beyond 40kHz.
Features
- Four input channels and eight output channels loudspeaker processor and matrix
- Analogue, AES3 and Dante™ digital audio inputs
- High performance 96kHz DSP
- Remote control and monitoring over Ethernet via Martin Audio VU-NET software
- FIR optimisation for Martin Audio’s O-Line
- VX limiting allows a passive enclosure the same protection as a fully active unit.
- Comprehensive suite of EQ’s, delays and all pass filters.
- Global mains operation 100-240V, 50-60Hz
Applications
- Loudspeaker system digital controller
- Front-of-house matrix to feed Dante digital audio to iKON amplifiers powering Martin Audio loudspeaker systems
- Use with Martin Audio O-Line for FIR Optimisation
- Use with Martin Audio U-Hub to feed digital audio and network to an MLA
- Series array/subwoofer array via a single cable
