How do I connect more than one monitor to a single output?The 8020A and 8030A monitors have an analogue XLR output connector which can be used to daisy-chain many units together. This output connection can be used for daisy-chaining up to six 8020A's or 8030A's together. The volume control of the first 'master' monitor can be used to adjust the level on the whole chain. The volume controls on the 'slave' monitors should be set fully clockwise.
The 8130A can be daisy-chained in both analogue and digital mode through the two male XLR output connectors on the back panel. Up to eight 8130A's can be daisy-chained.
With other models, you will need to make an adapter as shown below in the upper diagram. This parallel connects the inputs of monitor to the output of the source. The input impedance of all GENELEC monitors (except the discontinued 7050A and 1091A stereo subwoofer, which were not recommended for this type of connection method) is 10 kOhm, so up to 10 monitors can be connected to a typical line level output. Always check that the output will not be overloaded before connection. One of these adapters is required for each monitor in the chain except for the last one. The advantage of this connection method is that if one monitor loses its power then the other monitors are unaffected. The disadvantage of this connection method is that there is a limit to the number of monitors that can be connected to one output.
One other method commonly used is to connect a single output to all of the inputs of a 7050B, 7060B, 7070A, 7071A, 7073A, (1092A or 1094A) subwoofer - see lower diagram. Then each of the subwoofer outputs can be directly connected to any one of the active studio monitors in the bi-amplified range, e.g. 8020A, 8030A, 8040A, 8050A or 1032A. This works well as the subwoofer and other monitors can be positioned in the most suitable place for good sound coverage. If additional LF power is required use the "Sum Out" (not available on 7050A and 7050B) to connect more 7000 series subwoofers to the system.
It is important that all of the connections are made otherwise there could be a loss of input signal level (e.g. XLR pin 3 left floating) or induced hum (e.g. chassis ground and audio ground connected together) due to ground loops. Note: do not connect the XLR chassis to XLR pin 1, as this will compromise the RF immunity of the monitor's electronics.
