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 830S will respond to these
measures by performing at its best. Never stack the 830S directly on other
items of equipment. Vibrations from mains transformers and electromagnetic
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.

Configuring the tape monitor loop is described under Configuration menus -

Monitor.

Balance

Adjust the soundstage balance. To quit the balance menu, press the BALANCE
button a second time.
You will find a description of how to adjust the balance in Configuration menus

– Balance.

Analog inputs

The 830S is equipped with both balanced (XLR) and unbalanced (RCA phono)
analog inputs. Connect the outputs from your source equipment to the
appropriate inputs on your preamplifier.
Make sure that the plugs are a snug fit! Poorly fitting RCA plugs can detract
considerably from the sound quality of your hi-fi system. Use gold-plated plugs
whenever possible, as these have the lowest contact resistance.

Analog outputs

You can activate or deactivate both pairs of balanced outputs independently via
the "Output" settings in AMP setup. You can also adjust the level of Output 2
relative to the level of Output 1 in 0.5dB steps by up to ± 10dB.
This adjustment allows you to fine tune bass frequencies relative to mid/high
frequencies in a bi-amped system, or to adjust the level of a subwoofer.

Record output

The record output enables you to send the currently active input to a tape
recorder or the soundcard of your PC. The record output signal is the same level
as the input signal.
Record out must be activated via the configuration menu.

Monitor output

The 830S is equipped with a tape loop for off-tape monitoring during recording
or for inserting an external loudspeaker equalizer. Input 6 is the tape monitor
input. Please see Configuration menus - Monitor for more details.

Phono ground

External system ground connection, which can be used, for example, to connect
a turntable's ground cable.

Power connection

The power socket accepts standard IEC power connectors only. We recommend
you use a high quality, audiophile power cord. Your dealer will be happy to
advise you.

Power switch

The power switch fully disconnects the 830S from the AC mains supply.
