((Connecting Citation Amps In Mono (Bridged) Mode
Here's the how-to, right from the original H-K manual:
In order to operate the Citation II as a 120 watt monophonic amplifier it is necessary to fulfill two requirements:
1. The speaker output terminals must be strapped together. Tie the two ground terminals in parallel and then tie either the
two 8 or 16 ohm terminals in parallel depending on the nominal impedance of your speaker. For example, if you are using
an 8 ohm speaker, tie the two 16 ohm terminals together and attach the speaker between either 16 ohm terminal and
ground. If you are using a 16 ohm speaker it is permissible to connect it as described for an 8 ohm speaker, as a
mismatch of as high as 50% will not affect the tone quality.
2. The amplifier input terminals must be tied together if no preamplifier is to be used and the signal is being fed directly
by a tuner. If a monophonic preamplifier is used it is also necessary to tie the inputs together. This can be accomplished in
any of several ways. One method would be to use two patch cords with RCA type phono plugs on one end. The other
end of these patch cords would be tied together in parallel and soldered to another RCA type phono plug. Connect the
two individual RCA plugs to the input receptacles of the amplifier and the other end (which is paralleled) to the output of
your tuner. A more satisfactory method is to purchase a LAB-TRONICS patching plug, Part #A-7 54 to parallel the
inputs of the amplifier. This device would eliminate the need of soldering and would insure perfect connections.
3. If a stereo preamplifier is used input strapping is not required. Merely connect the two outputs of your preamplifier to
the corresponding inputs of the Citation II and connect the speakers as previously discussed.))
Yes, I would install an XLR for the inputs. I think noise rejection would be excellent. This should be the same as any other differentialy balanced amp which is what I should have. I also think the amp should have more than double the power this way. If anyone elso wants to weigh in you are welcome. Sorry to hijack the post though.
