Xilica DLP-4080A Digital Loudspeaker Controller
The DLP-4080A is a complete 4-input-8-output digital loudspeaker management system designed for the touring or fixed sound installation markets.
The absolute latest in available technology is utilized with 40-bit floating point processors 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. Precise frequency control is achieved with its 1 Hz resolution. Inputs and outputs can be charactersrouted in multiple configuration to meet any requirements.
The DLP-4080A can be controlled or configured in real time on the front panel or with the intuitive PC GUI accessed via the RS-232 interface.
Software upgrade for CPU and DSP via PC keeps the device current with newly developed algorithms and functions once available. Multiple setup storage and system security complete this professional package.
