Amplifier for DIN35 rail Item F502
This device, with hook for installation on DIN rail, allows installations mainly
in rooms of the service sector. Supplied directly at 230Va.c. it allows multiple
installations (maximum 40 amplifiers and 80 loudspeakers), thanks to the low
current absorption on the BUS (5mA).
Correctly configured you can have both a stereo and a mono signal in output
from the device to the loudspeakers. This type of amplifier can be connected
to 8Ω and 16Ω loudspeakers.
The amplifier can have two modes:
- “FOLLOW ME” mode: function which allows the same music in another
room after the amplifier of the room previously occupied has been
switched off and switching on the amplifier on the room you are now in.
- “NO FOLLOW ME” mode: when another amplifier is switched on, on
changing room, the source configured the same as the configurator
(inserted on M2) inserted on the amplifier switches ON, not necessarily the
source which was being listened to before.
The device can be controlled either directly by means of the buttons on the
front, or by the TOUCH SCREEN or by special controls item L4651/2 and Item
H4651/2.

4. The pushbuttons under “ON” and “OFF” are used:
• the “ON” pushbutton to switch on the amplifier (simple touch) and to
increase the volume (long press)
• the “OFF” pushbutton to switch off the amplifier (simple touch) and
to decrease the volume (long press). The LED positioned under the
pushbuttons indicate:
• the LED under “ON/OFF” indicates the amplifier state: if it is OFF there
is no BUS, if it is GREEN the device is in Stand-By, if it is ORANGE the
amplifier is ON
• the LED under “POWER” indicates: if it is OFF there is no voltage on the
POWER terminal, if it is RED the amplifier is switched on.
