unbalancedsignalontheleftchannel.
Theseconnectorsarewiredinparallel,thismeansyou
can use the second connector as a signal link connector.

In this case you can apply an input signal to the left channel only ! Leave the right channel
connectors open ! Bridge mode input level is controlled by the left channel level controller
(‘20’)only.Connectyourspeakertotherightchannel+(plus)connectorandtotheleft
channel+(plus)connector!Neverusethespeakeroutput–(minus)connectorsinbridge
