For output level control at the master unit only disable the L,R and M
output level controls on the slave units by removing the INT/EXT links
J35 and J36.
EXPANDING THE INPUTS WITH SYS-LINK
The number of input channels feeding the outputs may be expanded by connecting GR1 units together
using the SYS-LINK system. A single cable connects the L,R and M outputs of one unit to the buss
inputs of the next.
Use screened multiway cable connected as shown below to standard 15way D-type male connectors.
Do not interconnect the DIR OUTs to the AUX INs when linking L,R and M outputs. The example
shown below includes interconnection of the alarm override system so that one alarm source controls
all units simultaneously.
