M219 Additional room amplifier
M Series

(3) Voltage input IN (from serial #
2
000)
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 on
automatically and selects the input
LOCAL IN 1
. When the voltage is
removed from input
IN
, the
M219
switches off again automatically, as
long as no other source apart from
LOCAL IN 1
was addressed.
With DIL switch (3), you can define whether the volume control is
handled by the
M219
(
Floating Volume
) or the connected (TV) device
(
Fixed Volume
). With
Fixed Volume
, the
M219
’s volume control is
deactivated and the audio signal at
LOCAL IN 1
is transmitted with a
fixed strength. In this way, volume control is carried out with the TV
remote control.
The volume control setting set by DIL switch 3 only has an effect on the
local audio input
LOCAL IN 1
. All other sources are unaffected and
operate normally.

Application: Many devices output a voltage as soon as they are
switched on. If you connect the voltage output of such a
device with the
IN
voltage input on the
M219
and the
audio output with the local audio input
LOCAL IN 1
, the
M219
will switch on automatically with the other device
and transmit the sound.
If your device
doesn’t
have a voltage output, you can
supply voltage to the input using a sensor-switch multiple
socket outlet (Master/Slave socket outlet) and a normal
plug-in power supply (5-24 V= / DC). Please refer to the
diagram on Page 11.
