Introduction 1.1
ULTIMA 6 is an
incredibly reliable
and technologically
advanced stereo power amplifier.
It represents the entry into Chord
Electronics Full Size amplification
ownership with a dual-feed-
forward error-correction topology.
Before operation, we strongly
advise that you read this user
manual thoroughly, storing it
in a safe place along with your
original receipt of purchase,
in case you should require
assistance in the future.

Protection against
liquids & heat
1.2
The ULTIMA 6 is not
protected against liquids
of any kind. Never place
containers of liquid on ULTIMA 6.
Never allow ULTIMA 6 to come
into contact with moisture or
liquids; doing so could result in
electrocution or damage to the
ULTIMA 6 internal circuitry.
Be aware that liquids, including
water that has dried, can leave
minerals that can aect the
PCB and other components,
which could eventually lead to
oxidisation and short-circuiting.
If the ULTIMA 6 comes into
contact with moisture or liquids,
immediately disconnect from
the mains power supply, and
connected equipment, and
contact Chord Electronics for
further advice.
The ULTIMA 6 has
internal thermal
protection that will cut
the power supply if reached.
Never operate the ULTIMA 6 near
sources of heat or naked flames
as this will decrease the lifespan
of the internal components. It is
advised that you do not operate
the ULTIMA 6 in an area of direct
sunlight or on top of significant
heat- producing devices.
Please be aware that it is
entirely normal for the ULTIMA
6 to become warm during
use, particularly within a
stacked configuration. If you
are concerned about the
temperatures, please switch
the device o and consider a
dierent placement.

There are no user-
serviceable components
within the ULTIMA 6
or its power supply. Dangerous
voltages/currents exist within
the ULTIMA 6 and its power
supply, posing a severe risk of
electrocution and/or fire.
Never attempt to
open, dismantle or
apply internal third-
party devices to it or insert
anything other than the listed
interconnects or speaker cables
within this user manual.
If the ULTIMA 6 develops a
fault or the casework becomes
damaged, immediately
disconnect from the mains power
supply and connected equipment
and contact Chord Electronics
for further advice.

Dismantling & radio
frequency interference
1.3
With a thick, solid aluminium
chassis, the ULTIMA 6’s casework
largely protects the sensitive
internal circuitry from radio
frequency interference. However,
for optimal performance, it is
recommended that the following
points are observed:
1.Consider placing the
ULTIMA 6 away from
wireless routers.
2.Separate the
ULTIMA 6 from
amplifiers using
toroidal transformers.
3.Operate mobile
phones at a distance
to avoid interference.
Although the ULTIMA
6is largely shielded,
it can generate radio
frequency interference that
may have an eect on radio
and television reception. If this
occurs, please reconsider your
placement.

Before connecting the ULTIMA
6 to any equipment, consult the
manufacturer’s user guide to
confirm compatibility.
When connecting the ULTIMA
6 to any equipment, make sure
that all devices are o, including
the ULTIMA 6. Once connected,
switch all equipment on starting
with the source and ending with
the amplifier. Initially, operate
the ULTIMA 6 with your preamp/
and any connected sources on
their lowest gain settings and
lowest volume settings, gently
increasing to a comfortable
listening level. Never operate
the ULTIMA 6 at excessive
sound levels; permanent hearing
damage and loss can occur.
ULTIMA 6 is supplied with its
own grounded 16A-rated mains
IEC cable and it is important
that the amplifier is earthed at
all times via this cable, or an
appropriate alternative. Failure to
do this could be hazardous in the
unlikely event of a fault.
The supplied region-specific
16A mains IEC cable can be
substituted for an alternative
power cable, however, please
make sure that it has an earth. If
any cable becomes damaged you
must immediately discontinue
use and replace it to avoid the
risk of electrocution.
ULTIMA 6 must be permanently
connected to a source of power.
The included mains lead simply
plugs into the ULTIMA 5 IEC
mains socket. If the mains lead
is prematurely disconnected.
ULTIMA 6 may still hold charge
for up to 15 minutes.

WARNING: Never
disconnect the
power cable during

when ULTIMA 6 is o. If the
power cable is disconnected
during operation there is a
risk of damage to connected
equipment.
