INTRODUCTION
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.
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.
INSTALLATION
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
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.
