Maintenance - Genelec 4435A Operating Manual

be activated and adjusted with the Smart
IP Manager software. Powering down to
standby happens after a set time when
playback has ended. Playback automatically
resumes with an input signal exceeding the
level configured using the Smart IP Manager.
There is a slight delay in the automatic
powering up. If this is undesirable, ISS can
be disabled with Smart IP Manager.
The indented use of this loudspeaker
requires that the IP network interface is
continuously enabled also in the standby
mode. This enables the ISS to wake up with
an API command or in response to IP audio
stream. The power consumption in the ISS
state for 4435A is 4 W. To save more power,
the PoE+ power supply in the Ethernet
switch or PoE injector can be turned off.
However, loudspeaker wakeup will then take
slightly longer time and the loudspeaker
does not respond to any command on the IP
network while it is not powered.
Reset button
The factory setting for all acoustic settings is
"OFF", sensitivity attenuator set to 0 dB, and
delay set to 0 ms. These give a flat anechoic
response. Both the audio-over-IP stream and
analogue inputs are selected to play. Audio
stream settings are reset. With the factory
settings, all that is needed to play audio is
to provide a signal to the analogue input or
to configure an audio-over-IP stream in the
stream input. Set stream again to resume
normal streaming operation.
If necessary, the 4435A can be reset to
factory settings by inserting a pin through a
small hole on the front baffle, near the status
indicator LED (see fig. 1). Keep the button
pressed for over ten seconds. Do not use
excessive force. The loudspeaker indicates
that the reset process starts. Then you can
release the button but do not disconnect
power supplied by the Ethernet cable until the
reset process is complete. Once the reset is
complete, the loudspeaker becomes available
and active on the Smart IP Manager again.
This typically takes less than one minute.
Painting the loudspeakers
The loudspeaker metal mesh grille can be
spray painted to match the surrounding
colour. Do not paint the loudspeaker front
baffle and drivers, or try to paint the grille
while it is attached to the loudspeaker. Paint
the grille separately with a thin spray. Do not
use brushes or rollers. Be careful to avoid
clogging the grille with paint.
Status indicator LED
The LED light on the front baffle has some
status indication functions that are listed in
Table 2.
Automatic protection circuits
The 4435 system has protection circuits
against loudspeaker driver thermal overload
and amplifier overheating. The protection
system resets automatically so the user only
has to turn the input level down to ensure
that it does not reactivate.
Driver thermal overload protection
protects the drivers from damage caused by
prolonged overdriving with excessively high
or distorted signal. If this occurs, the circuit
automatically reduces playback volume. To
avoid this, lower the listening volume if the
sound becomes harsh and distorted at high
sound pressure levels.

Maintenance

There are no user serviceable parts within
the loudspeaker. Any maintenance or repair
should only be undertaken by qualified
service personnel.
Safety considerations
• Servicing and adjustment may only be
performed by qualified service personnel
• The loudspeaker must not be opened.
• Do not expose the loudspeaker to water
or moisture
• Do not place objects filled with liquid,
such as vases, on the loudspeaker or near
it
• This loudspeaker can produce sound
pressure levels in excess of 85 dB, which
may cause permanent hearing damage.
• Free flow of air behind the loudspeaker is
necessary to maintain sufficient cooling.
Do not obstruct airflow around the
loudspeaker
• The loudspeaker is not disconnected from
the power supply unless the CAT cable is
removed from the loudspeaker.
• Ensure that the mounting in the ceiling
is able to carry the full weight of the
loudspeaker in all circumstances, the
installations have been designed and
are implemented according to the local
safety regulations and follow principles of
good workmanship. Using a safery wire is
