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 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. 
 

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.  
 

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. 
 
Note- to reduce risk of damage to hearing and/or 
speakers, please reduce volume to minimum when 
changing the MM/MC switch.

CD

 inputs.

 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. 
 

 

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. 
 
AUX 2

AUX 2 

input, connect your external source to 

the 

AUX 2

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.
