STARTING . . . .
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 KW250S- the blue display 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.
VOLUME
The volume control knob, to the right of the front panel,
should be adjusted for normal listening levels.
Whilst being adjusted, the volume setting is shown in
the display window. The settings range from 0 to 100 in
1dB resolution steps giving about +19db out from the
preamp outputs at 100 setting.
Note: to prevent damage to hearing and speakers, the
switch-on volume setting is limited to 50 maximum.
Please readjust setting after switch on if necessary
PHONO INPUT
To use the phono input, connect your turntable
cartridge outputs to the phono input sockets (see p.8).
Pressing the phono button selects the corresponding
input.
Pressing a second time alternates the input for moving
magnet (MM) or moving coil (MC)
Choose the input that best describes the cartridge type
being used.
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.
CD
Selects the internal CD player. Please refer to p.10 for
advice and player functions.
TUNER
Selects the internal tuner. Please refer to p.14 for advice
and tuner functions.
AUX 1
To use the AUX1 input, connect your external source to
the AUX1 input (see p.8). Pressing the AUX1 button
selects the corresponding input. On AUX1 you have the
option of analogue line level,
or digital optical/coax inputs.
The unit switches automatically to digital inputs and
selects the correct one when a digital signal is present.
For sources with digital outputs, we recommend you use
the KW250S digital inputs to take advantage of the up-
sampling technology.
AUX 2
To use the AUX2 input, connect your external source to
the AUX2 input (see p.8).
Pressing the AUX2 button selects the corresponding
input. On AUX 2, you have the option of analogue line
level (rear phono plugs or front 3.5mm jack PDI input),
or digital coax input.
The unit switches automatically to digital input for
AUX2 when a digital signal is present.
For sources with digital outputs, we recommend you use
the KW250S digital inputs to take advantage of the up-
sampling technology.
The AUX 2/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.
