5. OPERATION
Connect the mains cable of the Project Eighteen to
an mains outlet.
Only after you have connected all other
components, you may switch the Project Eighteen
on with the ON/OFF switch (12.) on the rear panel.
From now on you should switch the power amp on
and off with the STANDBY button (1.) on the front
panel or the STANDBY button of another Sphinx
component connected to the optical CONTROL IN
jack.
This way all circuits will remain at working
temperature and the audio quality will be 100 %
within 15 minutes after activating. On top of that it
considerably increases the life span of the
component.
The Project Eighteen is in stand-by mode and the
LED (2.) shows a red indication.
Power On
You switch the Project Eighteen on with the
STANDBY button: the LED becomes green.
If you activate the power amp for the first time or
after a long period of non-use with the power 'off'
the amp will be at maximum performance after one
hour.
From stand-by mode it only takes around 15
minutes.
Power off
You switch the Project Eighteen off (stand-by) with
the STANDBY button (1).
Only if you will not be using the amp for a long
period (e.g. during holidays) we recommend
switching the amp off with the ON/OFF switch (12.).
Because in stand-by mode the Project Eighteen's
power consumption is still around the 70 W mark.
Warnings
1. Never put two amps on top of each other.
2. The component should not be subjected to
moisture of fluids.
3. Do not touch the component and the
loudspeaker outputs in particular with moist
hands: this powerful amp can output voltages in
excess of 36 volt.
4. Before removing the top panel, you should
disconnect the mains cable and wait at least 30
minutes (because the power supply remains at
the maximum voltage for a long time). Removing
the top panel does void your warranty though:
the panel should therefore only be removed by
an official Sphinx service engineer!
5. Before disconnecting a loudspeaker or audio
cable, please switch of the component with the
ON/OFF switch (12.)
6. An AC extension cord should never be used
wholly or partly coiled: this poses a severe fire
risk!
If you encounter problems...
If after power on the protection circuits detect
something wrong the Project Eighteen will
immediately switch to stand-by: the LED indication
will be red.
In almost all occurrences the problem has to do with
the loudspeaker cables.
Check every single one and solve the problem.
If you can't find the problem or the cause is
definitely not the cables, please contact your Sphinx
dealer.
Should for some reason the mains fuse be
destroyed you should replace it with a new one of
exactly the same type and rating:
5x20 mm
250 VAC / 6 A / slow
The fuse sits behind the cover in the mains
connector (13.).
Never use a fuse of a different rating: this could
lead to serious damage and may cause fire!
