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.
