Output Connections

WARNING: When driven to full power in Bridge Mode. There is more than 100Vrms
appearing in the Speakon™ jack which represent a significant shock hazard. Due
care should be taken when making any speaker connections.
There are two Speakon™ connectors. The Speakons are connected to the amplifier's outputs
whether the amplifier is in stereo, mono, or bridge modes (figure 1).
Speakon™ output A also doubles as the A&B/Bridge connector. This Speakon™ contains
both channels on one connector. This is convenient when connecting one speaker to the ampli-
fier in bridge mode where the speaker is connected across the positives of each amplifier output.
Configure the mode switch for bridge and connect the speaker to pins +1 and +2 of the bridge /
bi-amp Speakon (figure 3).
To connect a bi-amp speaker, configure the amplifier for stereo and connect to the bridge/bi-amp
connector but use all four terminals in the Speakon connector which will connect A and B outputs
separately to the speaker (figure 2). Connection configurations are labeled on the back panel.
