2.6 Installation and cooling
The unit can become hot depending on demanded output power and environmental temperature. Therefore
it is important, that the cooling air can flow unhinderedly into the air inlet in the bottom and flow out through
the holes in the rear panel. Direct exposure to sunlight is not recommended, this can heat up the unit.
2.7 Connection to mains
Connect the unit to the mains outlet by using the power cord which is (in some countries) delivered together
with the unit. Make sure that mains voltage is according to the value printed on the rear panel (near mains
connector (29)). Let the unit be switched off until all audio connections are made.
2.8 Connecting the analogue signal sources
Connect the outputs of your signal sources to the inputs (18, 19). The upper row of the RCA cinch
connectors (19, white) is for left channel, the lower row (19, red) is for right channel. The right (seen from
rear side!) XLR input (18) is for left channel, the other one for right channel.
NOTE: XLR input IN1 (18) and RCA-Cinch input IN1 (19) are internally paralleled and should only be
connected to a signal source alternatively.
If your amplifier is equipped with a built in phono preamplifier (option), connect the output of the turntable
with inputs (16) and connect the chassis ground wire to the ground connector (17).
2.9 Connection of digital sources (option)
SPDIF inputs
Sat receivers, CD drives, MD recorders and other can be connected to the optical or coaxial inputs (13, 14).
USB connector
Use a suitable USB cable and connect the USB input (12) to your computer. PC working with WINDOWS XP
or higher as well as most Apple computers recognize the USB input automatically. Installation of a special
driver software is normally not necessary.
To play music stored on your computer you must set it's output to USB and the volume to maximum. These
settings and how to create playlists, how to play certain music titles depend on the software you use. Please
refer to the corresponding software manual.
2.10 Connecting a recorder
Connect the recorder’s output to one of the inputs (18). The inputs of the recorder must be connected to the
fixed level outputs (20).
2.11 Connecting processors / equalizers
Connect the processor’s / equalizer's outputs to the inputs proc in (22). The inputs of the processor must be
connected to the outputs proc out (21). Additionally you must activate the processor loop (see 4.14)
