Output (Speakon-type Connectors / Terminals) in Normal Mode With TOUR GRADE amplifiers speaker connection differs depending on the actually selected mode of operation of the power amplifier blocks, i.e. the setting of the MODE switch on the power amp’s rear panel. In NORMAL mode, the loudspeaker systems can be connected in two different ways: using typical Speaker Systems Cabling or Bi-Amp Cabling. Typical Speaker System Cabling The first possibility is to use the two Speakon-type connectors, whereas speakers have tobe connected to pins 1+ and 1- of the sockets.
Speaker connection in NORMAL operation mode, using Speakon A and B connectors Next to the Speakon-type sockets, conventional speaker terminals are provided as well. The following illustration shows how to connect the speaker systems for NORMAL mode operation.
Speaker connection in NORMAL operation mode, using Terminals Bi-Amp Cabling The second possibility for connecting the speakers when the power amplifier is operated in NORMAL mode is to only use the Speakon-type connector CH A and to connect one speaker cabinet to pins 1+ and 1-, as described above and the second cabinet to pins 2+ and 2- as shown below. Only pins 2+ and 2- of the Speakon CH A connector are assigned. Proceeding like this facilitates the cabling of speaker systems that are used in active 2-way operation (Bi-Amp).
Bi-Amp speaker connection in NORMAL operation mode, using only the Speakon A connector Output (Speakon-type Connectors / Terminals) in Bridged Mode Setting the Mode switch on the power amp’s rear panel to BRIDGED lets the power amplifier run in bridged mode operation and speaker connection has to be established using pins 1+ and 2+ of the Speakon socket CH A.
Speaker connection in BRIDGED operation mode, using Speakon A When using the speaker terminals in BRIDGED mode, the loudspeaker system has to be connected to the red terminals of CHANNEL A and CHANNEL B. An illustration of how to correctly establish speaker connection for this mode of operation is provided on the power amp’s enclosure.
Speaker connection in BRIDGED operation mode, using Terminals CAUTION: Due to the high current, using banana plugs for speaker connection is not permissible.
