INSTALLATION
KW550
INTRODUCTION
INSTALLATION
Congratulations on the purchase of your new KW550
integrated valve preamp dual mono power amp.
Great attention has been paid to internal layout,
isolating each circuit section to prevent possible
interaction.
The preamplifier sections are our finely tuned and
tweaked tube input line level tube preamplifier which
uses 6SL7s for smooth sound coupled with low noise
and virtually no distortion. This also includes our top
quality low noise phono stage which caters for both MM
and MC cartridge users.
Position the KW550 on a stable, horizontal surface
where there is no risk of it being knocked, or subjected
to vibration such as from loudspeakers.
Protect your KW550 from humidity - if the unit is
moved from a cold place to a warm room, or in
generally humid conditions, moisture can form on the
inside of the unit. If this happens, leave the unit for an
hour or so to allow sufficient time for the moisture to
evaporate.
AUDIO CONNECTIONS
The power amplifier consists of two mono block
amplifier modules with completely separate supplies for
the absolute best in separation and imaging. Rated for
550W nominal they are enough to drive even the most
demanding loudspeakers with ease. Low distortion and
very quiet they will deliver all music types exactly as the
artist originally intended.
The resultant performance achieved by this unit is
among the best in the world. It has excellent signal to
noise ratio, low distortion, wide bandwidth, huge
dynamic range, extraordinary resolution and fine detail.
Outputs: Connect your loudspeakers to the terminals on
the back panel marked as LEFT and RIGHT
SPEAKER outputs.
Preamp outputs RCA sockets are controlled by the
volume and source controls. This allows connection of a
second amplifier for bi-amping.
Tape outputs of nominal line level and are constant
volume for recording to tape, CD-R/RW, or any other
recordable format.
IMPORTANT
Do NOT ground either of the speaker output terminals.
They are BOTH ‘live’, and grounding either will cause
permanent damage to your KW550.
Inputs: The KW550 has five line level inputs and a
Phono MM/MC input. PHONO MM/MC, CD, AUX
1/PDI, AUX 2, AUX 3, and TAPE inputs are available
at the back for connection to signal sources.
A Portable Device Input (PDI) 3.5mm stereo jack is
provided at the front which is shared with the AUX 1
rear inputs. This allows easy connection of a portable
player.
CLEANING
Before cleaning the unit, switch off power at the mains
switch and remove the mains plug from the wall socket.
Clean the cabinet and remote control unit using a moist
cloth. We do not advise using solvents, white spirit or
thinners as they could damage the surface finish.

REMOTE CONTROL
KW550
The universal remote control shown below enables functions from this and related units to be operated from a convenient distance.
Equivalent buttons on the remote control have the same functions as those on the front panel of the unit. Other functions are only
available by remote control.
As the handset uses an invisible infra-red light beam, the front edge must be pointed directly towards the receiver window at the
front of the player, without visual obstruction between them.
If the range of the remote control greatly decreases, replace the batteries with new ones. Do not mix old and new batteries - two
are required, size AAA, LR03 or SUM-4.
Please dispose of used batteries in accordance to local regulations.

AMPLIFIER CONNECTIONS
KW550
All input, output and power connections should be
made with the mains power switched OFF.
The KW550’s PRE OUT RCA sockets would therefore
be connected to the input of the external “woofer”
amplifier in this example.
If you are in doubt about bi-amplification, please
contact your dealer for advice.
INPUT CONNECTIONS
Phono: The KW550 has a pair of RCA type phono
input sockets intended for use with moving magnet
(MM) or moving coil (MC) pickups. Some
turntable/pickup arm combinations are fitted with an
extra wire for chassis earth. This should be connected
to the earth terminal on the back panel.
TAPE OUT and MONITOR: The KW550 has a
single tape output with facilities for recording material
to a suitable line-level recorder such as tape, CD-R/RW,
minidisk etc.
The tape deck's line inputs are connected to the units’
TAPE OUT sockets to record the material being
listened to. The line outs should be connected to the
unused of the AUX inputs. The TAPE MONITOR
button switches output to allow listening to material
being recorded without swapping leads around.
Line level inputs: The unit also has five stereo pairs of
RCA “line level” input sockets controlled by the
internal volume setting.
They all have the same input sensitivity, and are
therefore suitable for use with any source component
having a line output of 300mV nominal. The sockets
on the rear panel are marked, CD, AUX 1, AUX 2,
AUX 3 and TAPE corresponding with function
selector buttons on the front panel. The AUX1 input
sockets on the back share the same input as the PDI
input jack at the front.
Do not connect devices to both the AUX 1 and PDI
inputs simultaneously. Please see note P.11
OUTPUT CONNECTIONS
Speakers: Connect your loudspeakers to the terminals
on the back panel marked as LEFT and RIGHT
SPEAKER outputs. Make sure both speakers are
connected with the same polarity.
PRE-: The KW550 has its pre-amplifier output
available from RCA sockets on the back panel marked
PRE-OUT, and is controlled by the volume
adjustment.
This is to allow “bi-amplification” using suitable
external amplifiers and crossover networks to power
the speaker drive components separately, giving
noticeable improvement in clarity, imaging and bass
weight. In this arrangement, typically the KW550
speaker outputs may be used to drive the speaker’s
“tweeter” (high audio frequencies), and an external
higher power stereo amplifier(s) could drive the
“woofer” (low frequencies).

AMPLIFIER OPERATION
KW550
STARTING
If the rear AUX 1/PDI connectors are used, please
ensure you disconnect any devices and wires connected
to the front PDI socket.
Failure to do so could result in equipment
malfunction.
Once all connections are made, switch on the unit, using
the POWER button to the bottom left of the front panel,
the front panel of the KW550 and the feet will light
indicating that the unit is on. The feet glow red to
indicate speaker outputs are muted, for about fifteen
seconds, so no sound will be heard from your speakers.
Once the 15 seconds is up, the feet glow orange to
indicate unit is usable, but still warming up. At this
stage sound output is now available. After 30 minutes,
the feet glow blue to indicate unit is fully warmed up.
AUX 2
To use the AUX 2 input, connect your external source to
the AUX 2 input (see p.7). Pressing the AUX 2 button
selects the corresponding input.
AUX 3
To use the AUX 3 input, connect your external source to
the AUX 3 input (see p.7). Pressing the AUX 3 button
selects the corresponding input.
VOLUME
The volume control knob should be adjusted for normal
listening levels.
Note: As a safety precaution and to prevent damage to
hearing and speakers, the volume control will reduce its
own setting if severe output overload is experienced.
TAPE
To use the TAPE input, connect your external source to
the TAPE input (see p.7). Pressing the TAPE button
selects the corresponding input.
PHONO INPUT
To use the phono input, connect your turntable
cartridge outputs to the phono input sockets (see p.8).
The phono switch above the inputs selects the
corresponding gain suitable for the cartridge being used,
MM or MC.
You can also select the PHONO input by using the
remote handset, (see p. 9) but MM/MC switching is not
available on the remote.
RECORDING
To record, to any format of your choice, simply select the
required source with the input selector button on the
front panel or remote control. This source will now be
routed to the KW550 TAPE OUT for recording by tape
deck, CD recorder DAT, minidisk, or computer
soundcard input. You will also be able to hear the
selected source through the loudspeakers by pressing the
TAPE MONITOR button from any other input. Press
again to return back to the input being listened to.
Note- to reduce risk of damage to hearing and/or
speakers, please reduce volume to minimum when
changing the MM/MC switch.
Note - adjustment of the volume control has no effect on
the recording level.
CD
Selects the source connected to CD inputs.
AUX 1 or PDI
To use the AUX 1, connect your external source to the
AUX 1 input (see p.7). Pressing the AUX 1 button
selects the corresponding input. The AUX 1/PDI input
is also available at the front of the unit in the form of a
3½ mm jack PDI (Portable Device Input) socket to
enable personal/portable devices such as MP3 players
and minidisk walkman to be played thorough the unit.
TIP: For best listening experience using your portable
device, we recommend you set its outputs for “line
level” use, as opposed to “headphones”, if the option is
available. Please refer to your portable device’s manual,
for more details
Note: Please note the sockets PDI at the front and
AUX 1/PDI at the back are electrically connected
together:
If the front PDI socket is used, please ensure you
disconnect any devices and wires connected to the rear
AUX 1/PDI connectors.
