Ultima is equipped with both inverted
and non-inverted balanced XLR inputs
as well as inverted and non-inverted
unbalanced RCA inputs. Ultima has no
ability to switch between the inputs
therefore, only one must be used.
Invertion relates to the phase of
the incoming signal. During normal
operation for Chord Electronics
products, the use of the inverted inputs
is advised, however, you may select
non-inverting if desired.
When using a pair of Ultimas please
take great care to connect both
amplifiers with the same invertion to
avoid an out-of-phase configuration.

As Ultima is a mono amplifier, it only
supports a single speaker output,
however, it has four speaker terminals.
Both positive speaker terminals
originate from the same source, as
does the negative speaker terminals.
Do use the additional two postive and
negative terminals if you wish to bi-wire
your speakers.
In order to connect Ultima to
loudspeakers, use high-quality
loudspeaker cable terminated with
4mm banana plugs or 6mm spades.
Bare wire can be used, but it is not
recommended.
Connect the black (negative) terminal
from Ultima to the negative terminal on
your loudspeaker and the red (positive)
terminal from Ultima to the red positive
terminal on your loudspeaker. Repeat if
you wish to bi-wire the same speaker.
