The RCF DX 4008 4-Input & 8-Output Digital Audio Processor is a digital loudspeaker management system, designed for the touring or fixed sound installation markets. This loudspeaker has a built-in 32-bit (40-bit extended) floating point processor and high-performance 24-bit analog converters. The high-bit DSP prevents noise and distortion induced by truncation errors of the commonly used 24-bit fixed-point devices.

A complete set of parameters include I/O levels, delay, polarity, 6 bands of parametric EQ per channel, multiple crossover selections, and full function limiters. The DX 4008 Loudspeaker can be controlled or configured in real time on the panel or with the intuitive PC GUI accessed via the RS-232 interface.

The software upgrade for CPU and DSP via PC keeps the device updated with the algorithms and function. Multiple setup storage and system security complete this professional package.
