Arcam Logo Speaker System User Manual


 
E-4
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.
