Outputs
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.
