[7] CHANNEL SELECT
Stereo/ Mono switch
Using the Channel Select switch, you can adjust the operating mode of the two
music (stereo) channels, to the requirements of the room where the M219 is
installed. Three operating modes are available:
1) Stereo
The left music channel is reproduces through the left speaker connector
and the right channel through the right connector.
2) Inverse stereo
After installation, it can occur that the left and right speaker connections
have been inverted or that the sound picture is not correct for the normal
listening position. In this case, a quick solution is offered with the Inverse
stereo operating mode, which inverse the assignment of the left and right
speaker connectors.
3) Mono
If only one speaker is connected to the M219, or if the M219 is controlling
two speakers, each in a different room, you should select the Mono
operating mode. This means that each speaker receives all the music
information.
The configuration of the Channel Select switches is described on the next
page.
[6] IN Voltage input (from serial #
2000)
Using the voltage input IN on the M219, the local audio input LOCAL IN 1 can be
activated by the application of 5 – 24 VDC. This means that as soon as the voltage
is present at IN, the M219 switches automatically to LOCAL IN 1, irrespective of
which source had been selected previously.
For further information please refer to DIL switch (3) /
Page 11.
Please note:
The voltage input IN is galvanically isolated from the M219 with a high-
resistance (10kΩ) optical coupler. This stops any disturbances from either side
having any effect.
