Stereo wiring

Both binding post and Speakon® connectors are provided for each channel, these are internally wired in parallel so either or both may be used. Note that it is possible to lever the caps out of the ends of the binding posts to insert 4mm banana type plugs but this will invalidate the product safety approvals in some territories. The side entry positions for these connectors should therefore be used if possible.

Stereo operation

If you are using the binding posts, for non bridged operation the loudspeakers should be connected between the RED and BLACK binding post terminals or the Speakon® 1+ & 1- pins. The amplifier will be non- inverting with respect to the RED terminal and 1+ Speakon® pin.

More than one speaker can be connected to each channel as long as the total impedance per channel is not less that 2 ohms. See section 7.0d of this manual for more information about how to calculate impedance.

Bridge mono operation

To use the amplifier in bridge mode, for binding post connection, the speakers must be connected between two RED terminals leaving the BLACK terminals unconnected. In bridge mode the amplifier is non- inverting relative to the 1+ pin of the Speakon® connector and the channel 1 RED binding post.

If the Speakon® connector is used, switching the amplifier in to bridge automatically takes care of the Speakon® wiring for you. Therefore the loudspeaker connector is WIRED THE SAME WAY AS FOR NON BRIDGE MODE, i.e. between 1+ and 1-. This significantly simplifies the speaker wiring enabling the same leads to be used for bridged and non-bridged modes. Channel 1 output carries the bridged signal. During bridge mode operation no connector should be inserted into the channel 2 output.

More than one speaker can be connected to the bridged pair of channels as long as the total impedance is not less that 4 ohms. See section 7.0d of this manual for more information about how to calculate impedance.
