High performace DSP processor
The DSM-428 is a powerful speaker management processor with four analog inputs, an AES/EBU input and eight analog (12dBu) outputs. All inputs and outputs offer 10 PEQ bands and a frequency range up to 26 kHz. The rugged analog input stage accepts input voltages of up to +23dBu thus matching any source on the market today, with an excellent dynamic range of 118dB. Using a switch-mode power supply for clean power supply rails and superior ruggedness, 64-bit digital processing and some of the best converters available on the market today, the DSM-428 offers sound quality that sets standards in professional as well as high-end home audio. Controlled via the front panel or via the remote control application, the DSP settings and coefficients are calculated on-the-fly at the moment of changing the parameters. Frequencies can be set with 1Hz accuracy, delays with 15 microseconds’ accuracy, and gains with 0.01dB accuracy. When editing values via the front panel, some values are limited in granularity; e.g. gain is set via 0.25dB steps in this case.
