Positioning the unit
<
Place the Logo speaker unit on a level, firm
surface, avoiding direct sunlight and sources of 
heat or damp.
<
Do not place Logo in an enclosed space such
as a bookcase or closed cabinet unless there is 
good provision for ventilation. The Logo speaker 
unit is designed to run warm during normal 
operation.
<
Do not place your record deck on top of Logo.
Record decks are very sensitive to the noise 
generated by mains power supplies which will 
be heard as a background ‘hum’ if the record 
deck is too close. Vibrations from Logo may also 
cause the pickup stylus to jump tracks.
Power
Logo is supplied with a moulded mains plug already 
fitted to the lead. Check that the plug supplied fits 
your supply – should you require a new mains lead, 
please contact your Arcam dealer. Logo is fitted with 
a transformer designed to accept nominal mains 
voltages from 100V to 240V.
Push the IEC plug end of the power cable into the 
socket on the back of Logo, making sure that it is 
pushed in firmly. Plug the other end of the cable into 
your mains socket and, if necessary, switch the socket 
on. 
Logo is fitted with a main power switch on the rear 
panel, above the power inlet: make sure that this is 
switched on to use Logo.
If your Logo is not to be used for a prolonged period, 
switch the unit off at the main power switch.
Indicator LED
An indicator LED is positioned across 
the top edge of Logo’s cabinet. 
When the indicator LED is off, it 
indicates that the speaker is completely 
disconnected from the mains. A blue 
light from the indicator shows that the speaker is 
powered up and ready for immediate use. A red 
light from the indicator shows that the speaker is in 
standby (power-saving) mode and will power up as 
soon as an audio signal is received.
Standby switch
The push-in
STANDby
switch provides two
settings:
AUTO
and
MANUAL
.
‘
AUTO
’ (button out) switches Logo’s
amplifier to standby after a period of
idleness (about 15 minutes) when no audio signal has 
been received. ‘
MANUAL
’ (button in) means that Logo’s
amplifier is on whenever the unit is receiving mains 
power.
Interconnect cables
We recommend the use of high-quality screened 
audio interconnect cables. Poor quality cables will 
degrade the performance of your system. All cables 
should be kept as short as is practically possible.
It is good practice when connecting your equipment 
to make sure that the mains power-supply cabling is 
kept as far away as possible from your audio cables. 
Failure to do so may result in unwanted noise in the 
audio signals.

Connecting to a sound source
Check that your sound processor/receiver is switched 
off before connecting Logo. Failure to do this may 
result in both speaker and amplifier damage.
If your sound source has a 
PRE-OUT SUb
or
LFE OUT
output, connect this to
IN LFE
on the back panel using
RCA (phono) connectors at each end. If your sound 
source does not have a SUB or LFE output, connect 
the left and right channels of the stereo pre-amp 
output (
PRE OUT L
and
PRE OUT R
) to
IN L
and
IN R
,
respectively.
You may connect both the 
LFE
and the
L
and
R
outputs to Logo if you wish to use both the LFE 
channel and to supplement the bass response of 
‘Large’ Left and Right speakers.
OUT L
,
OUT R
and
OUT LFE
provide line-level outputs
for ‘daisy-chaining’ further units, in a multi-room 
installation, for example.
After connecting
Turn the sound source amplifier volume down to 
minimum before switching on. Switch the source 
amplifier on, select a source signal, then gradually 
increase the volume to the required listening level.
Care of your speaker
Running-in
In the same way as a new car requires a ‘running-in’ 
period, so do all loudspeakers. Your Logo may sound 
good when you first connect it, but with time it will 
improve dramatically. Expect about 50 hours use 
before the full potential of your Logo is realised.
Cleaning
To clean your speaker simply use a soft, slightly 
dampened cloth to wipe off any dust or dirt. Do not 
use solvent-based or chemical cleaning products as 
these may damage the finish of the speaker cabinet.
Power handling
Arcam speakers are designed to reproduce recorded 
music under normal domestic conditions. We do 
not recommend nor warrant them for commercial 
applications, such as discothèques, public address, etc.
Note: When connecting Logo to signal leads,
or when moving Logo to a new position, make sure
that the unit is not receiving power by switching off
and disconnecting the power lead.
