ULTIMA 3 | Manual
_
ULTIMA 3 is equipped with
both inverted and non-inverted
balanced XLR inputs as well
as inverted and non-inverted
unbalanced RCA inputs. ULTIMA
3 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 by removing
the cap covering the XLR input.

If you remove the cap please
take great care to connect
both amplifiers with the same
invertion to avoid an out-of-
phase configuration.
If using ULTIMA 3 with older
models of Chord Electronics
monoblocks please note the
inputs will be reversed.
WARNING: ULTIMA 3 must
be connected to a dedicated
preamplifier, or a device
capable of attenuating its
output. Failure to attenuate
the volume before it enters
ULTIMA 3 could result in
irreversible hearing damage,
speaker damage and could
void the warranty.
