External speaker connection
OMT CD – Edition: 13.08.2007
21
The impedance of all external speakers
per channel in ”Stereo” mode should
not be less than 8 ohms, because the
cabinet speakers represent a load of
already 8 ohms per channel. If the
amplifier is operating in 2-Channel
mode, the internal speakers are all
loaded to the RH channel (Channel 1);
the LH channel (Channel 2) now
applying to the screw terminals
”Externer Lautsprecher - External
speakers” may be loaded with max. 4
ohms.
The amplifier applies approx. 55 watts
(rms on max. 0.1% dist.) on a 4 ohms
speaker per channel, 18 watts to a 12
ohms speaker and approx. 9 watts to a
24 ohms speaker. That means, that
e.g., a 12 ohms speaker connected to
the external channel at Dual Channel
operation must be a type of at least 18
watts, otherwise the speaker is in
danger of destruction at higher
volumes. Note that speaker groups like
in hi-fi boxes may have, at certain
frequencies, impedance’s much lower
than their rating. Make sure that all
speakers are connected in correct
polarity.
