MIDI / RS232
The MIDI Cables
Use standard 5-pin 180 degree DIN type male-to-
male MIDI cables. These should be available from
your local audio dealer or music shop. The cables
should not exceed 15 meters (50 feet) in length.
To control external equipment plug console MIDI
OUT to external equipment MIDI IN. To control the
console plug external equipment MIDI OUT or
THRU to console MIDI in.
Make sure the same MIDI channel number is
selected on the console and external equipment
you want the console to communicate with.
RS232
Set the rear panel switch to RS232 if you need to
load in new console operating software or interface
to a PC via its serial port. The Allen & Heath ML
Archiver software provides archiver and snapshot
manager functions that run on a PC.
Note:
The console takes longer to boot after power
up when the rear switch is set to RS232. This is
because it interrogates the port for a code update.
For normal operation the MIDI position is
recommended.
MIDI Overview
The
ML3000
includes a Musical Instrument Digital
Interface (MIDI) port. Standard 5-pin IN and OUT
sockets allow connection to external MIDI
equipment such as computer show control systems,
sequencers, instruments and data archiving
devices. Applications include sophisticated ‘hands-
off’ scene control, effects and instrument patch
control, switching of signal processing remote
controllers, and archiving of the console settings
and memories for later re-use.
