PRE-AMPLIFIER OUTPUT
The kW 500 Integrated amplifier 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 com-
ponents separately, giving noticeable
improvement in clarity, imaging and bass
weight.
In this arrangement, typically the kW 500’s
speaker outputs are used to drive the speak-
er’s “tweeter” (high audio frequencies), and
an external stereo amplifier drives the
“woofer” (low frequencies).
The kW 500’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.
BEFORE SWITCHING ON
Connect the two accessory power supply
leads into the
RIGHT
and
LEFT PSU
(
P

S

U

INPUT
sockets at the
rear of the amplifier. The other ends of the
leads plug into corresponding marked sock-
ets on the back panel of the power supply
unit.
A single lead with smaller plugs connects
between the
PRE-AMP PSU
sockets on
each unit.
Plug the accessory IEC mains lead into the
rear PSU mains socket, then the other end
into a wall outlet. Turn the volume control
on the front panel to low (anticlockwise).
All input, output and power connections
should be made with the mains power
switched OFF.
INPUT CONNECTIONS
The kW 500 Integrated amplifier has a pair
of phono inputs for moving magnet (MM)
pickups.
Some turntable/pickup arm combinations
are fitted with an extra wire for chassis
earthing. This should be connected to the
earth terminal on the back panel.
The kW 500 also has five “line level”
inputs which are electrically identical, and
therefore suitable for use with any source
component having an output of at least
300mV. The sockets on the rear panel are
marked
CD
,
SACD
,
TUNER
,
AUX
iliary,
and
TAPE
, to correspond with function
buttons on the front panel.
Using good quality co-axial audio leads,
connect the left and right outputs from
your CD player, tuner or phono/record
deck to the appropriate RCA input sockets
on the back panel.
Connect the kW 500’s
TAPE
input sockets
to the line output of your tape recorder,
and kW 500’s
TAPE RECORD
output
sockets to the line input sockets of the tape
deck.
OUTPUT CONNECTIONS
Connect your loudspeakers to the terminals
on the back panel marked as
LEFT
and
RIGHT SPEAKER
outputs.
