ULTIMA 2 is equipped with both
inverted and non-inverted balanced
XLR inputs as well as inverted and
non-inverted unbalanced RCA inputs.
ULTIMA 2 has no ability to switch
between the inputs, therefore, only one
must be used.
Inversion 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 by removing
the cap covering the XLR input. If
you remove the cap please take great
care to connect both amplifiers with
the same inversion to avoid an out-of-
phase configuration.
As ULTIMA 2 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 do
the negative speaker terminals. Do
use the additional two positive and
negative terminals if you wish to bi-wire
your speakers.
In order to connect ULTIMA 2 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 2 to the negative terminal
on your loudspeaker and the red
(positive) terminal from ULTIMA 2
to the red positive terminal on your
loudspeaker. Repeat if you wish to bi-
wire the same speaker.
WARNING:
ULTIMA
2 must be connected
to a dedicated
preamplifier, or a device
capable of attenuating its
output. Failure to attenuate
the volume before it enters
ULTIMA 2 could result in
irreversible hearing damage,
speaker damage and could
void the warranty.
