Back panel connections
A2 / TV
Universal line level pre-amp input for connecting any audio sources or TV sets.
A1 / PH
Universal pre-amplifier line input
This input can be upgraded to form an input for an analogue turntable by fitting
a Phono MM or Phono MC module (optional accessories).
The
phono modules can be precisely matched to your pick up system
using the adjustment switches of these modules. For further information please
consult the operating manual of the phono module.
GND
Ground terminal
The ground lead from an analogue disc player is connected here in order to
avoid hum.
A3 / TUNER
Universal line level pre-amp input for connecting any audio sources like tuners
DISC / MUSIC PLAYER
Input sockets for connecting a
MUSIC PLAYER or a CD player.
RECORD
Input and output sockets for connecting devices which can record and play back
(recorders).
PRE OUT
Pre-amplifier output for external power amplifiers or active speakers.
R und
L
(loudspeaker terminals)
One pair of loudspeakers can be connected to the amplifier (SPEAKER
R
and SPEAKER
L
). The impedance of each speaker must not be lower than
4
Ω
(DIN rating).
The output stages are designed to cope with a minimum load of 2
Ω
, but conti-
nuous operation at very high volume produces high currents in the power output
stages which can lead to overheating. This in turn trips the protective circuit
which switches the amplifier off automatically.
Caution!
Make sure that the terminals are firmly screwed down, and that no
short-circuits are possible as a result of projecting cable ends or errant wire
strands.
Note:
If the loudspeakers are to be used in countries outside the EU the red/black
stoppers can be removed from the loudspeaker terminals. The speakers can
then be connected using banana plugs.
The stoppers are simply a push-fit in the terminals, and can be prised out from
the rear using a suitable tool such as a knife blade.
