Independent SMPS Modular Amplifier. Each amplifier channel is completely independent of each other. Even when the amplifier frame is loaded with more than one amplifier module, models can safely be changed without affecting the other.
Each amplifier has a power on/off switch allowing for unused amplifiers to be powered off for energy saving.
AC & DC dual power operation. Normal power operation via the AC 117v or 220velectrical power input. Amplifier will switch automatically to DC24V battery backup supply input when AC power is interrupted.
Overheat, over-current, speaker shortage and module socket contact protection circuitry.
Signal, Clip, and Protect LED display monitoring of the amplifiers
Independent channel remote power on/off of each module via TCP/IP or contact closure
Independent channel remote volume controle via TCP/IP
The DPA-4300M can drive either 70V or 100V output lines.
HPF(High Pass Filter) for protection of speaker and voice intelligibility: 20Hz/200Hz / 400Hz (-3dB)
Input Trim control on each amplifier 0 dB ~ -12 dB (factory default) or 0 dB ~ Minimum
Connection and cabling is made easy using removable screw type Euroblock terminals for connection to input and output terminals
A user-friendly GUI facilitates controlling and monitoring of the amplifier.
High Definition Audio with S/N better than 70dB and THD less than 1%
