** PLEASE NOTE THIS IS THE NON-DANTE VERSION OF THE DX4.0 **
Connected via Ethernet, system remote control and monitoring is done via Martin Audio’s VU-NET proprietary software application, while a front panel interface gives local control of features.
Four analogue/AES3 inputs and eight analogue/AES outputs are available, with AES3 inputs and outputs selected in pairs.
The DX4.0 features a sophisticated loudspeaker limiter suite which incorporates peak, RMS and excursion limiting, as well as multiband limiting for passive two-way systems. High-pass filtering, three shelving filters and six parametric filters are provided for each input channel, with crossover filters, two shelving filters and eight parametric filters on each output channel.
The DX4.0 supports FIR filters for use with optimisation of Martin Audio’s O-Line and can also be used with Martin Audio’s U-Hub to feed digital audio and network to an MLA Series array/subwoofer array via a single cable.
