(A discussion on serial- and parallel connection of several speakers and the resulting impedance is
not translated, as it is not considered relevant today.)
It is recommended to use twisted speaker cables, especially on left channel when using the
intercom functionality. If not, voltages will be induced in the left speaker cable causing hum when
used as a microphone.
Polarity
When two speakers are close to each other, the polarity must be correct, i.e., the speaker cones
must move in phase. If the polarity is wrong, the cones will move out of phase of each other. This
will have a negative effect when the two speakers are sufficiently close to each other. Bass tones,
in particular, will be attenuated.
Lytt og Tal (Listen and Talk)
With a separate speaker connected to the outlet tagged “Sep. Venstre” (Separate Left), you may
engage in a conversation with people in the room where you have your separate speaker. The Sep.
(separate) and App. (main) speakers will then work both as speakers and microphones. With the
speaker selector in position “Tal” (Talk), left App. (main) speaker will function as a microphone and
in position “Lytt” (Listen,) left Sep. (separate) speaker will work as a microphone. The volume can
be adjusted with the outer volume knob.
“Lytt”and “Tal” can also be used while listening to the radio, tape or records, because “Lytt” and
“Tal” only affects the left channel. Radio, tape or record playing will continue on the right channel.
To listen in on the room with the Sep. (separate) speakers while listening to the radio, tape or
records, keep the speaker selector in “Lytt”. This can be used as a babysitter function. If you switch
the speaker selector to “Tal” (Talk) to give a message to the person in the other room, the other
program will automatically be disabled. The continuous bass- and treble controls are disabled on
the left channel during “Lytt” and “Tal”.
