The Allen & Heath Sys-Link Option is a single expansion card with two 37-pin D type connections for audio input and output. The Sys-Link Option combines two Allen & Heath GL2400 consoles for double the channel count. The consoles are linked with two 37-pin D-sub cables (not included) and establishes Master/Slave operation for double the inputs and outputs while monitoring on the Master console's monitoring section.
Note! Both Master and Slave consoles must have the Sys-Link V2 option card installed.
