DC 4000


DC 4000 Controller

Digital 2-In/4-Out speaker controller / signal processor with routing matrix

The DC4000 is a digital 2-in / 4-out speaker management system with 32 bit and 96 kHz sampling rate. The DC4000 is equipped with 2 analog inputs, 4 analog outputs and two remote-connectors (USB and RS485). The use of modern and fast DSPs enables a latency (analog to analog) of 0,625 ms only. Each input channel includes 6 equalisers (with low-shelf, high-shelf and parametric function), and a delay function. The polarity of each input channel can be switched from + to -. Each output channel includes 6 equalisers (with low-shelf, high-shelf and parametric function) and a delay function. The HPF (high-pass filter) and the LPF (low-pass filter) is part of each output channel. Both offer three different operation modes: Linkwitz-Riley, Butterworth and Bessel (up to 48 dB/Oct). Each output channel includes a high performance limiter. The integrated flash memory chip offers space for 30 presets which can be loaded via the preset-menu, three default-buttons or the PC remote software.


► 2 inputs and 4 outputs with free routing
► Intuitive handling at the front-panel and via PC software

► Up to 250 units can be controlled in a RS485 network



PC Remote Software

The DSP can be adjusted and controlled with the free PC software. This software is a professional tool and enables a quick and effective programming of presets in real-time (online or offline). The program shows adjustments of any filter in a graphic simulation. All DSP-functions and adjustments can be loaded, edited and saved with this tool. The software is compatible with WINDOWS 98©, WINDOWS 2000©, WINDOWS XP©, WINDOWS VISTA©, WINDOWS 7© and WINDOWS 8©(all 32-bit and 64-bit versions).
