3. OPERATING DETERMINATIONS
The digital effects mixer EX-820 with two stereo input channels and a VCA crossfader has been specially
designed for DJs. The built-in digital effect processor allows for producing eight different effects for the
stereo channels or for the master signal, and BPM counting. Three further crossfader effects are available
for an automatic or manual crossover function. The unit offers prefader listening to all audio sources via
headphones. The characteristic of the channel faders and the crossfader is adjustable.
For connection to a computer, the unit is equipped with a USB audio interface (USB 1.1 compatible). The
two USB ports operate in full duplex mode, i.e. each port may be simultaneously used as an output (for
digital output of the master signal to the computer) and as an input (for transmitting audio files from the
computer to the mixer).
