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 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 Owner's 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
amplifier.

• 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 unit 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 pin from the plug. It is there to ensure your safety.

• Route 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, during electrical
storms.

• If you have an external antenna or a cable antenna connected to your hi-fi system,

we recommend that you use a signal-isolating filter to avoid interference or
damage during thunderstorms.

• 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.

852 Dual Mono Power Amplifier

• Place your amplifier on a stable support. We recommend you use a solid hi-

fi rack. In our experience, you will achieve good results with racks fitted with
MDF shelves. Glass, metal or stone being less suitable for use as hi-fi
equipment supports. Never stack the 852 directly on other items of
equipment. 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 all system components are operated from one mains socket.

You can achieve this by connecting all system components through a
single, high quality mains distribution board. The lower the resistance
between signal sources and amplifiers, 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 also important. Use a phase
finder to determine which pin is life. Mark the appropriate side of the power
outlet. The marked pin on the IEC power receptacle on the 852 should
connect to the positive conductor.

• Cleaning and maintenance. To clean your amplifier, use a soft cloth. To

remove stubborn dirt from the front panel, use a proprietary glass cleaner.
Do not use water! Never use solvents or white spirit. These will cause
irreparable damage to the surface of the unit.
