Important Safety Precautions
•Use only an approved power cable and plug or distribution board to connect your
amplifier to a power outlet. Do not use an extension cable.
•Never touch the mains plug if your hands are wet.
•Do not attempt to open the equipment. Refer servicing and repair to qualified
service personnel. Touching live components inside the case can result in a fatal
electrical shock!
•Read the Owner's Manual and Safety Precautions before operating the equipment.
•Keep this Manual in a safe place so that you can refer to it later.
•Please heed all warnings on the equipment itself and in the Owner's Manual.
•Please follow the instructions contained in your Owner's manual and never use this
equipment for any purpose other than is explained in this Owner's Manual.
•Only connect this equipment to a power source of the type described in the Owner's
Manual and specified for this equipment.
•Make sure that there is adequate ventilation around the equipment to allow proper
cooling. Keep the equipment away from direct sunlight. Avoid installing the unit
close to sources of heat or in spaces such as bookshelves or cupboards where heat
radiation may be obstructed. Avoid excessive temperatures in the room, as these
could ultimately damage sensitive components and reduce the service life of your
player.
•Never use the unit in damp rooms, at temperatures of below 15°C, or in the open air.
When bringing your amplifier in from the cold, allow it time to achieve room
temperature before plugging it in.
•Always switch the unit off before removing or inserting interconnects. Doing this
with the amplifier switched on can damage not only the amplifier itself but also
equipment connected to it.
•If you ever spill water or any other liquid onto the equipment: Do not touch the case!
Remove the plug from the wall outlet and contact your dealer or our service
department.
•Never remove the earth connection from the plug. It is there to ensure your safety.
•Arrange the power cable so that no one can accidentally stand on it. Avoid locating it
under objects that might put pressure on the cable. Pay particular attention to areas
where the cable exits from plugs, AC outlets and from the unit itself.
•Never operate the unit without being present. Disconnect the plug from the wall
outlet and remove all aerial connections (including cable aerials) when: you clean
the unit, you do not expect to use the unit for long periods of time, during an
electrical storm.
•If you have an external antenna or cable antenna connected to your hi-fi system, we
recommend that you use a signal isolating filter to avoid interference or damage
during thunderstorms.
•Problems: If you lose the sound while the amplifier is operating, or if you notice
smoke or burning, switch the unit off immediately and contact your dealer or our
service department.
•Only replace defective fuses after you have traced and removed the cause of the
fault and then only with a fuse of the same rating. Remove the mains plug before
changing fuses. Use an insulated screwdriver to remove and replace the fuse.

•Place your control amplifier on a stable support and use a spirit level to make
sure it is perfectly level. We recommend the use of a solidly constructed hi-fi
rack with adjustable shelves. In our experience, you will achieve good results
with racks using MDF shelves. Glass, metal or stone being less suitable for use
as hi-fi equipment supports. Avoid placing the control amplifier close to
loudspeakers or any other source of vibration. The 830 will respond to these
measures by performing at its best. Never stack the 830 directly on other
items of equipment. Vibrations from mains transformers and electro-
magnetic interference from other components can have a negative impact
on the control amplifier’s sound quality. 800 series products are not suitable
for installation in enclosures such as 19” racks or cabinets. The on/off switch
at the rear of the unit must always be accessible.
•Take some time to organize your cabling. Try to keep power cables away
from interconnect and speaker cables. Shielded power cords can significantly
reduce the transfer of interference to your signal cables.
•Make sure that the polarity of the mains wiring is the same for all system
components. You can achieve this by connecting all system components
through a single high quality mains distribution board. The lower the
contact resistance between the power outlets of your signal source and your
control amplifier, the less the audio signal will be polluted and the better
your hi-fi system will sound. Connecting your components with the correct
mains polarity is particularly important. Use a phase tester to determine
which pole is life. Mark the appropriate side.
•Cleaning and maintenance: To clean your control amplifier, use a soft cloth.
Use a proprietary glass cleaner to remove stubborn dirt from the front panel.
Do not use water! Never use solvents or white spirit. These will cause
irreparable damage to the surface of the unit.

•The 832 is in standby mode. -> Press the POWER button.
•The 832 is not connected to a power outlet, or the power switch (on the
rear panel) is in the off position. -> Plug the 832 into a power outlet and
switch the unit on.
The display illuminates but there is no sound:
•The volume setting is too low. -> Turn up the volume.
•There is no signal from the source component or the wrong source has
been selected.
•The unit is in Mute mode. -> Press the MUTE button.
•The Max Volume setting is too low. -> Increase the Max Volume setting in
the configuration menu.
•The Tape monitor loop is active (Monitor appears in the display), but there
is no signal to Input 5 (monitor input).
The unit does not respond to the remote control.
•The remote control batteries are discharged or have been inserted
incorrectly. -> Change the batteries.
•The distance, or angle, between the remote control handset and the 832 is
too great.
•The IR receiver on the 832 is obstructed. -> Make sure that there is clear
line of sight between the remote control and the IR receiver.
