4 Installation and power supply
Important
· During connecting and removing of sources or amplifiers to the
SAM 20 SE all units of your audio system have to be switched off to
prevent damage of the SAM 20 SE or any of the other connected
units.
· Please make sure that all cables are in absolute best conditions!
Broken shields or short-cut cables could damage the SAM 20 SE
and/or any other connected unit.
4.1 Placement
Important
· It is recommended to place the SAM 20 SE into a high quality rack or
onto a stable table.
· Do not expose the unit to direct sunlight.
· Do not cover the ventilation slots.
· Do not place the SAM 20 SE in close range to heat sources like radia-
tors.
· Do not place the SAM 20 SE on top of other units, especially not on
top of power amplifiers, pre amplifiers or similar that produce heat.
Both units could suffer damage from thermal overload.
· Do not use the unit in places where it is exposed to vibrations.
· Do not place the unit close to loudspeakers or into the corner of a room
where it is exposed to high levels of sonic energy, which might reduce
the sound quality of the unit.
4.2 Mains connection
The mains input 9 * is on the back panel of the SAM 20 SE. To connect the
unit to mains use the included mains power cord. If you prefer to use a different
power cord make sure that it meets the specifications for your home country.
*
see numbers in section 'Overview back panel' on page 8.
10
Important
· The electrical specifications of your home country must meet the
electrical specifications printed onto the back panel.
· The SAM 20 SE is a Class I unit and must be earthed. Please ensure a
stable earth connection. Phase ('hot' pin) is marked on the back panel
('PHASE') 11 .
· If you connect the mains power cord please make sure that mains
switch 10 at the back panel is switched off.
· Never pull the mains plug while the SAM 20 SE is switched on! Before
you pull the mains power cord off its socket 9 at the back panel, power
down the unit to stand-by mode and switch off the unit using mains
switch 10 .
Only in cases of extended absence – like vacations – or if massive trouble
on the mains power is to be expected you should switch off the SAM 20 SE
from the mains using the mains switch 10 . To disconnect the unit completely from mains pull the mains plug.
Tip
· The use of high quality mains power cords could improve sound qual-
ity. Ask your local dealer for more information.
4.3 Orientation of mains plug
The correct polarization of mains is important for reasons of audio clarity
and stability. Please connect the mains power cord so that the hot pin of
the wall outlet is connected to the pin of the mains input 9 marked
'PHASE' 11 .
11
5 Inputs and outputs
Important
· During connecting and removing of sources or amplifiers to the
SAM 20 SE all units of your audio system have to be switched off
to prevent damage of the SAM 20 SE or any of the other connected
units.
· Please make sure that all cables are in absolute best conditions!
Broken shields or short-cut cables could damage the SAM 20 SE
and/or any other connected unit.
5.1 Inputs
The SAM 20 SE is equipped with four RCA inputs 2 to 5 and one balanced (XLR) input 1 for connecting signal sources at line level. RCA
input 6 is dedicated to connect a turn table.
Please connect the left and right input of the same number printed on the
back panel of the SAM 20 SE to the corresponding output of the source
you would like to connect to the SAM 20 SE.
5.2 Speaker terminals
Connect your speakers to the terminals 7 and 8 on the back panel of the
SAM 20 SE. You can use banana plugs or spades as well as simple cable
ends. Look out for the correct connection of your speaker cables. Usually,
the terminals of your speakers are marked '+' and '-'. The SAM 20 SE uses
the same marks.
Note
· Wrong speaker polarization will result in severe loss of sound quality.
· In case you would like to bi-wire your speakers please insert the cable
to the tweeters from the rear using banana plugs and mount the cables
to the bass speakers from the side. In doubt please ask your dealer for
assistance.
12
Important
· Although the SAM 20 SE has an effective protection system to pre-
vent damage to the circuits, switch off the unit while working on
the speaker and/or audio cables.
· The nominal loudspeaker impedance has to be at least 4 Ohms or
higher.
· Never use force or tools tightening the terminal screws.
5.3 Preamplifier Output
The SAM 20 SE is equipped with a pair of RCA preamplifier outputs to
connect e.g. an additional amplifier or a subwoofer.
Please use high quality interconnectors to connect the PRE OUT 16 of
your SAM 20 SE with an additional amplifier or subwoofer.
5.4 Recording devices
You can connect one recording device to the SAM 20 SE for recording and
playback.
Connect your recording device (like DAT or tape recorder) to the recording
output REC OUT 15 of the SAM 20 SE. For playback please connect
your recording device only to input no. 5 IN 5 5 of the SAM 20 SE, if it
is also connected to the output REC OUT 15 of your SAM 20 SE. If you
select input no. 5 IN 5 5 the output REC OUT 15 is switched off to prevent any feedback loops between your recording device and the
SAM 20 SE.
Please use inputs no. 1 1 to no. 4 4 and no. 6 6 to connect sources you
like to record from. With these inputs the recording output
REC OUT 15 is always active.
13
5.5 Phono
The SAM 20 SE is equipped with a phono preamplifier board. Use the input no. 6 IN 6 6 marked as PHONO to connect your turntable to the
SAM 20 SE. Connect the earth wire of your turntable to the earth connector GND 13 . For further information on the phono preamplifier board
please refer to section 'Phono ' on page 34.
Important
· Input no. 6 IN 6 6 must only be used to connect a turntable.
· Input no. 6 IN 6 6 is not available for By-Pass mode (see section 'By-
Pass Mode' on page 24).
5.6 Headphones socket
A 6.3 mm headphones socket 14 is located at the rear of your SAM 20 SE.
The signal at this socket can be switched on and off to allow the headphones to be plugged in permanently. Switching is easily done on the front
panel. Please refer to section 'Headphones' on page 21.
5.7 Audionet Link
For your convenience, the SAM 20 SE can switch on/off all other Audionet
units (e.g. power amplifiers) connected via Audionet Link by a simple
touch on the remote control or the power key on the front panel.
You only need a simple optical 'Toslink' cable. Connect the Audionet Link
output Link OUT 12 of your SAM 20 SE to the Audionet Link input of
the unit to be controlled.
