the settings. Attach the plexiglass over the
switch groups with two Phillips screws when
you have completed the adjustments. Do not
overtighten the screws.
Status indicator LED
The status indicator LED on the RAM1
changes colour to indicate amplifier status.
If the LED is yellow, it indicates that the
amplifier is in “STANDBY” mode. When the
amplifier is switched to “ON” mode, the LED
changes to green colour.
Automatic protection circuits
The AIW26B 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. The circuit automatically
reduces the volume of the channel that is
being overloaded. To avoid this, lower the
listening volume if the sound becomes harsh
and distorted at high sound pressure levels.
Amplifier thermal protection turns the
amplifier to “STANDBY” mode if the amplifier
overheats. Let the amplifier cool down and
check that there is sufficient clearance
around the amplifier for cooling (see chapters
“Space requirement for the RAM1 amplifier”
and “Mounting the RAM1 amplifier to an
equipment rack” above). If the problem
persists, consult your Genelec dealer or
Home Theater Installation company for an
improved cooling solution for your equipment
cabinet or rack.
Maintenance
There are no user serviceable parts within
the loudspeaker or the amplifier. Any
maintenance or repair should only be
undertaken by qualified Genelec service
personnel.
Safety considerations
• Servicing and adjustment must only be
performed by qualified Genelec service
personnel. Do not undo any screws on
the amplifier unit.
• It is forbidden to use this product with
an unearthed power cable, which may
lead to personal injury.
• To prevent fire or electric shock, do not
expose any part of the system to water
or moisture. Do not place any objects
filled with liquid, such as vases, on the
RAM1 amplifier or near it.
• Switch off the mains power from the
amplifier if the system is not used for
long periods of time.
• Note that the RAM1 amplifier is not
completely disconnected from the AC
mains service unless the mains power
cable is removed from the amplifier or
the mains outlet.
