Brief description
The DPA POWER AMPLIFIERS in the DPA 8000 series are class-D amplifiers and can be
operated from both the mains and a DC supply. The output voltage is galvanically isolated and
is constantly monitored for ground fault. An energy-saving mode and temperature-controlled
fan reduce energy consumption and noise levels. The control and monitoring functions are
performed via REMOTE CAN BUS. The DPA POWER AMPLIFIERS are designed for operation in
an emergency sound system. The amplifiers are usually controlled via the DPM 8016
PROMATRIX CONTROLLER and configured using IRIS-Net. To use a DPA without the DPM
8016, a configuration can be created using IRIS-Net and stored permanently in the DPA. The
desired configuration (preset) is then applied each time the DPA is restarted.
System overview
The PROMATRIX 8000 system includes the following power amplifiers:
•
DPA 8150 with 1 x 500 W
•
DPA 8225 with 2 x 250 W
•
DPA 8412 with 4 x 125 W
All power amplifiers have the following features:
•
Ungrounded 100-volt power outputs (internally reconfigurable to 70 V or 50 V)
•
Amplifier blocks in class-D technology
•
Outputs idling and short circuit-protected
•
Mains operation 230 V/120 V AC and/or 24-V DC emergency backup
•
Electronically balanced inputs
•
Temperature monitoring function
•
Pilot tone and ground fault monitoring function
•
Malfunction message via potential-free READY contact
•
Processor control of all functions
•
Monitoring of the processor system via watchdog circuit
•
Non-volatile FLASH memory for configuration data
•
Internal monitoring function
•
Integrated audio relays
•
Line monitoring function
The power amplifiers are processor-controlled and equipped with extensive monitoring
functions. A watchdog circuit is built in to monitor the processor system. Line monitoring for
the CAN bus and for audio transmission allows line interruptions and short-circuits to be
detected and indicated to the user. The power amplifiers for the PROMATRIX 8000 system can
be configured quickly and easily using the IRIS-Net software. The properties can be configured
using a graphical dialog-based user interface.
