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.

830 Stereo Control Amplifier
•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 are 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
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.

Inputs
In addition to the general configuration described earlier, which works equally
on all inputs, you also have the option of adjusting individual inputs to match
different signal sources.
Name (input name)
You can assign whatever name you wish to the inputs. Press the LEFT or RIGHT
button to select the desired input (1-6) and confirm by pressing OK. An A< will
now appear in the display, at which point you can enter the name you want to
use. Use the UP or DOWN button to select letters or special characters. Use the
LEFT or RIGHT button to move to the letter you wish to change. Names may be
up to 8 characters in length. Once you have finished entering the name, confirm
it with the OK button.
If you have an 820 connected to your system (SYSCOM), the names of its digital
inputs will appear on the 830. You can only change the names of the digital
inputs via the DAC menu on the 820.
Enable (activating inputs)
It is always advisable to disable any inputs that are not being used. When
selecting inputs, any input that has been disabled will be skipped.
Gain (input sensitivity)
You can assign a different input sensitivity to each input. This can be useful when
your source components have different output levels. The sensitivity settings are
-6dB, 0dB und +6dB and the maximum permissible input voltage for the 0dB
setting is 6.0V.
Coupling (DC filter)
You can assign a different input coupling to each input. The standard setting is
DC input coupling, which means that there is no coupling capacitor in the signal
path. If a signal source contains a DC component that could potentially damage
amplifiers and speakers – noticeable, for example, as a gentle thump when
switching from one source to another or when adjusting the volume – you
should select the AC (AC input coupling) setting, which will filter the AC
component from the music signal. The AC setting can also be used to filter
unwanted subsonic frequencies from the signal: the cut-off frequency is 16Hz.

Fix to 0dB (bypass)Fix to 0dB (bypass)
The Fix to 0dB feature simplifies the integration of the 830 within a home cinema
system. It allows you to switch each input individually to a 0dB mode in which
the signal is passed from input to output without either gain or attenuation.

When you assign Fix to 0dB to an input, it passes through the preamp without
any change in level. When you switch to another input, the preamplifier will use
the last gain setting you used.

This feature is useful if you wish to use the stereo channels from a surround
sound decoder as the front channels. The gain is then controlled by the decoder.

The 830 is able to communicate with other compatible Lindemann components
via SYSCOM. This Link Mode allows a single remote control to be used for all
Lindemann components.

Lindemann components.
To use this feature, all components must be linked with a SYSCOM cable (see
diagram below). You must switch off all components before changing any
SYSCOM connections, as a re-start is required to ensure that the system
recognizes all of the components.

Important: You can only control the 820/822 CD player and 830 preamplifier
with the same remote control when Link Mode is active; otherwise, both
components could react simultaneously to commands such as volume, etc. The
two components should be positioned directly adjacent to or above and below
each other to ensure that both remote sensors receive commands from the
system remote at the same time.
