Address 0 (00 hex, default setting) separates the DPA
power amplifier from the remote communication. Despite
being connected to the CAN bus, the amplifier does not ap-
pear in the system.

STATUS LED I
NDICATOR
The following operating states are signaled by the status
LED indicator of the REMOTE CAN BUS on the rear of the
appliance:
• Continuous light: Firmware update or configuration update is in prog-
ress
• Flashing (50 ms ON, 50 ms OFF): FIND function is activated
• Activated for 100 ms: Data is sent via the REMOTE CAN BUS
• Flashes periodically every 3 seconds for 100 ms: The set CAN add-
ress is "00", the power amplifier does not appear on the REMOTE
CAN BUS
• Flashes periodically every second for 100 ms: Normal operation, no
data transfer

2.8 Supply Voltage

Generally, the DPA power amplifier is operated via the
mains input with AC voltage (switchable between 115 V
and 230 V). A battery input is additionally provided for
emergency power supply operation (24 V DC voltage).

The connection between the mains outlet
and the power amplifier's mains input has
to be established using the supplied IEC
mains cord only. Always separate the pow-
er amplifier from all supply voltage sourc-
es during installation. When connecting
the power amplifier to the mains make
sure that the used power source complies
with the voltage requirements specified on the amplifier's

type plate. The mains fuse holder is located directly below
the mains input and facilitates the comfortable exchange
of the fuse, without need to open the unit.
Mains Voltage Selector Switch
The mains VOLTAGE SELECTOR
switch allows switching between 230
volts and 115 volts.
NOTE: The default mains voltage setting of the
power amplifier is 230 V AC. If the appliance
is to be operated on 115 V AC, the mains
fuse has to be replaced by a slow-blow fuse
with a rating of 10 ampere, carrying the
imprint "T10A".

AINS WITCH
When switched to OFF, the POWER switch
(mains switch) on the rear of the appliance
separates the power amplifier from the
mains. When switched to ON, the power am-
plifier starts booting. A soft-start circuit pre-
vents inrush current peaks. The switching of
the loudspeaker systems is delayed, which
effectively suppresses switching noise.
DC I
NPUT
In case of a mains voltage breakdown, the
DPA power amplifier automatically
switches to DC power supply. For this to
be effective, connect a 24 V DC power
source to the DC INPUT. The DC input is
protected against inverse polarity and
overload. The corresponding fuse is located inside the
power amplifier and is not accessible from the outside.
CAUTION: It is not possible to deactivate the DC input.
The POWER switch is only for switching off
the mains.

2.9 Installation

The DPA power amplifier is designed for horizontal instal-
lation in conventional 19" rack shelves. In general, the lo-
cation has to be chosen carefully, so that the amplifier is
protected against the following:
• Drops or splashing water
• Direct sunlight
• High ambient temperatures or direct radiation of heat sources
• High humidity or moisture
• Heavy dust
• Massive vibrations
