Cooling
Cooling in use
Due to the substantial power of the Mono X Signature, forced air-cooling
is provided via two fans. The fans in the Mono X Signature feature an
Intelligent speed controller. When the unit is idling the fans turn off.
As the amplifier warms up the fans progressively speed up, reaching
maximum speed at maximum temperature. In this way the fan speed
is always related to the power output of the unit and fan noise is barely
discernible even at low volume levels. Whilst listening to music during
quiet passages, the fans may slow down or in some cases stop altogether
to avoid encroaching on the listening experience.
Cooling in standby
If the amplifier is set to Standby whilst the case is still hot, the fans will
switch in at full speed, cooling the case before setting to Standby. During
this period the INPUT indicator will glow red, extinguishing when the
cooling cycle is complete.
TROuBlEShOOTING GuIdE
If your Mono X Signature is not operating properly, disconnect the power
and check all connections using the notes in this handbook. If problems
persist, the checklist below may be helpful.
If you are in doubt, consult your dealer.
No sound from one or all speakers
Check that the pre-amplifier and
the power amplifiers are on.
Check that the correct amplifier
input is selected.
The standby lights should be
green.
The INPUT indicator will glow
green for balanced input, orange
for RCA/phono.
Check that the loudspeakers are
connected.
The connection at the terminals of
the loudspeakers and the Mono X
Signature should be checked.
Your amplifier has a unique fault indication system to help you to diagnose
problems. Fault condition messages will be displayed via the Standby and
Input/Mute indicators in the event of a system fault.
INPUT indicator flashing between red and the normal input colour
The amplifier has overheated.
The amplifier will automatically
run the fans at full speed until it
has cooled to a safe temperature,
it will then return to Standby,
ready for normal operation. Check
to ensure there is adequate
ventilation for the amplifier.
STANDBY indicator flashing orange/green
The
amplifier
has
been
overloaded.
Check
that
the
speaker
connections are correctly made
with no possibility of a short-
circuit. If the problem persists,
the speaker impedance may be
too low.
STANDBY indicator flashing red or red/orange
The amplifier has an internal
fault.
Switch off the amplifier, disconnect
it from the system and return it for
service.
