KW550 AMPLIFIER CONNECTIONS
Issue 1: August 2006 Page 10 of 14
All input, output and power connections should be
made with the mains power switched OFF.
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.
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).
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.
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.
