AP4722 ML3000 SYS-LINK Applications Note 2
Connecting Two ML3000 Consoles
1. Connect the slave console SYS-LINK A and B outputs to the master console SYS-LINK A
and B inputs using the two 37way cables provided. Connect the slave console SLAVE (to
master) logic port to the master console MASTER (from slave) logic port using the 9way
cable provided. Make sure the cables are correctly plugged in and secured using their
locking screws.
2. Use a pointed object to select the underpanel SLAVE MODE switch above the LRC
faders on the slave console. Make sure this switch is in its normal up position on the
master console. If you have changed the setting of the switch turn power off and on
again to boot the console into its new mode.
Connecting the ML3000 to an ML4000 or ML5000 Console
1. Connect the ML3000 slave console SYS-LINK A and B outputs to the master ML console
SYS-LINK A and B inputs using the two 37way cables provided. Connect the ML3000
SLAVE (to master) logic port to the ML SIDECAR LOGIC 1 or 2 logic port using the 9way
cable provided. Make sure the cables are correctly plugged in and secured using their
locking screws.
2. Use a pointed object to select the underpanel SLAVE MODE switch above the LRC
faders on the ML3000. If you have changed the setting of the switch turn power off and
on again to boot the console into its new mode. It is not necessary to change any mode
on the ML4000 or ML5000.
The Connections
Audio cables: Male 37way D-type plug
both ends. Shielded 36 core cable. The
cables are wired one to one with shield
connected to pin 19.
Logic cable: Male 9way D-type plug both
ends. RS422 cable.
Audio signals are balanced with low
impedance outputs and high impedance
inputs. Operating levels are 0dBu except
for PFL/AFL which is –8dBu.
For custom application of these
connectors make sure any unused audio
inputs are linked to 0V to prevent
interference pickup via the cable.
