4 Installation and power supply
Important
· During connecting and removing of sources or amplifiers to the
SAM G2 all units of your audio system have to be switched off to
prevent damage of the SAM G2 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 G2
and/or any other connected unit.
4.1 Placement
Important
· It is recommended to place the SAM G2 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 G2 in close range to heat sources like radiators.
· Do not place the SAM G2 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 G2. To connect the
unit to mains use the included mains cord. If you prefer to use a different
power cord make sure that it meets the specifications for your home country.
Important
· The electrical specifications of your home country must meet the
electrical specifications printed onto the back panel.
*
see numbers in section 'Overview back panel' on page 8.
9
· The SAM G2 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 cord please make sure that mains switch
10 at the back panel is switched off.
· Never pull the mains plug while the SAM G2 is switched on! Before you
pull the mains 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 G2
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 cords (e.g. Audionet P10) could im-
prove sound quality. 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 cord so that the hot pin of the wall
outlet is connected to the pin of the mains input 11 marked 'PHASE' 9 .
Your Audionet SAM G2 is able to detect a wrong polarization of the
mains plug during start-up. If the message
► Attention: ◄
► Mains phase incorrect ◄
appears in the display, switch off the unit and flip the mains plug in the
wall outlet (see section 'Mains phase detection' on page 15).

5 Inputs and outputs
Important
· During connecting and removing of sources or amplifiers to the
SAM G2 all units of your audio system have to be switched off to
prevent damage of the SAM G2 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 G2
and/or any other connected unit.
5.1 Inputs
The SAM G2 is equipped with five RCA inputs 2 to 6 and one balanced (XLR) input 1 for connecting signal sources at line level.
Please connect the left and right input of the same number printed on the
back panel of the SAM G2 to the corresponding output of the source you
would like to connect to the SAM G2.
5.2 Speaker terminals
Connect your speakers to the gold plated terminals 7 and 8 on the
back panel of the SAM G2. 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 G2 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 ca-
ble 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.
Important
· Although the SAM G2 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.
