New system configurations are possible with the abundant number of audio channels. The 4 inputs and 8 outputs allow stereo 4-way, stereo 3-way + mono 2-way, 4 bi-amp mixes and 8-channel zone capability. The DXP4800 enables the audio engineer to come up with creative system architectures via the 4 x 8 matrix feature and programmes allow for fast A/B comparison, and the matrix feature allows any of the four inputs to be assigned or mixed to any output, say Community.
The audio converters in the DXP4800 offer high quality signal reproduction, distortion and noise, with a sampling rate of 96 kHz and signal-to-noise ratio optimized at around 115dB (unweighted). The employed DSP is a true 32-bit (40-bit extended) floating point DSP (600MFLOPS peak) - which prevents induced noise introduced by the truncation error resulting from fixed-point calculations. The performance is far superior to the 24-bit fixed point DSPs that are widely used in the industry today, says the manufacturer.
The DXP4800 can be controlled via front panel controls or remotely by PC via RS232. The firmware of the unit can be flash upgraded when new features become available, eliminating frequent upgrade of the hardware for new software functions.
