AMX AXB-MIDI User manual

axb-midi midi interface
The versatile AXB-MIDI can receive data from two independent MIDI IN A
and MIDI IN B ports to provide automated control of audio mixers, routers,
and other MIDI-compatible devices. MIDI IN A and IN B arecombined to
THRU and OUT, and can be re-patched under software control. Internally-
generated MIDI commands are sent to OUT.
MIDI bus activity can be monitored from four front-panel LED indicators.
The MIDI Interface can extend control up to 3,000 feet using the AXlink
data/power bus. The optional AC-RK Accessory Rack Kit is available for
rack mounting.
