SIGNAL PROCESSORS
DIGITAL CHANNEL DIVIDER
D2040
■ High-performance stereo 4-channel (2-in/8-out)
digital channel divider.
■ RS-485 serial interface allows external computer
control over all parameters.
■ Top-performance A/D and D/A converters provide
outstanding audio quality, with 110-dB signal-tonoise ratio and frequency response of 20 Hz to 20
kHz.
■ Independent crossover filter, EQ, compression and
digital delay available on each channel.
■ Fader settings and digital parameters can be stored
to 15 user memory locations.
