2 GL2800/ GL3800 SYS-LINK Applications Note AP6284

Linking consoles

SYS-LINK V2 to V2 connection

SYS-LINK V2 to V1 connection

37way male to 25way male D-type cable wired as shown below. Minimum 18-core shielded cable with

screen soldered to chassis at both ends. Maximum cable length 2.9 metres.

Custom applications

To connect other audio equipment using the SYS-LINK connectors always ensure unused audio inputs

are linked to 0V ground at the input connector. This is to prevent interference pickup on unterminated

high impedance inputs. Do not link unused outputs to ground. Connect line level signals of -2dBu.

Use balanced connections where possible. For unbalanced signals link signal ‘-‘ to 0V. To activate

PFL/AFL link PFL DC to 0V through a 15k ohm resistor (37 way Pins 3 to 1).

If you require further information or advice please contact Allen & Heath technical support.

Plug the ‘slave’ console SYS-LINK V2 outputs

into the ‘master’ console SYS-LINK V2 inputs.

Make sure the connectors are fully plugged in

and their securing screws tightened.

If linking to a 4 bus console such as a

MixWizard or GL2400, use a single 37way

cable and plug into the socket marked ‘A’.

37way male to male D-type

cable wired one to one. 36-

core shielded cable with

screen soldered to pin 19.
