Output connections
The loudspeaker output connections are performed using a speakon and 2-pin terminal block (5.08 mm
pitch) connector for every output. Both connectors are linked in parallel, allowing free selection and the most
suitable connection for every application.
The used speakon connectors are 4-pole types, containing the output signal for the corresponding channel
on +1/-1 terminals. The speakon connector for the first (and third for SMQ) channel also contains the output
signal for the subsequent channel on +2/-2 terminals. This allows to transfer of two amplifier channels over
one four-conductor loudspeaker cable which is fitted with one connector. Connection in bridge mode can
also be made using one single connector
