GL2800/ GL3800 SYS-LINK Applications Note AP6284 1

SYS-LINK explained

SYS-LINK (system link) is the Allen & Heath connection standard for linking two consoles together to

expand the number of input channels feeding the mixes. One becomes the ‘slave’ to the other ‘master’

console. All the slave console mix busses including main LR, groups and auxes connect directly to the

master console mix busses without using up valuable input channels. The PFL/AFL system is also

linked so that all channels can be monitored using the master console headphones and meters. The

slave console master section is not used as its signals are taken before the mix inserts and output

faders. Both consoles must have the SYS-LINK option fitted. A pair of multiway cables is all that is

required to link the GL2800/ GL3800 to another 8 bus Allen & Heath console fitted with SYS-LINK.

(A single cable may be used to connect to a 4 bus console such as a MixWizard

or GL2400.)

SYS-LINK versions 1 and 2

The GL2800 and GL3800 use the more recent SYS-LINK Version 2 standard. This benefits from

balanced interconnections which allow longer cable length with less chance of noise and interference

pickup than the earlier, unbalanced SYS-LINK Version 1. Both versions operate at -2dBu line level. V1

uses the 25way D-type connector. V2 uses the 37way D-type connector. Two consoles fitted with SYS-

LINK V2 can be linked using two 36-core shielded cables wired one to one to two 37way male D-type

connectors. It is also possible to connect between SYS-LINK V2 and V1. This requires 37way to 25way

adapter cables wired to unbalance the connections. Wiring details are provided later in this document.

The interconnecting cable is not included in the kit and should be sourced elsewhere or ordered

separately from Allen & Heath.

GL2800/GL3800 SYS-LINK V2 input and output option

Option kit GL28/38-SLV2 is available from

Allen & Heath. This can be installed in the

GL2800 or GL3800 console to provide

both SYS-LINK V2 input and output. The

console may be used as either a ‘slave’ or a

‘master’. For information on fitting the option

refer to document AP6159.
