Digital 2-Channel DSP Amplifier with Network Connection Network compatible, DSP-controlled high performance amplifier with 4 input channels and 2 output channels. CLASS D amplifier technology with 2000 W output power at 4 ohm per channel. Remote control and monitoring possible via PC and control software. Network-compatible in combination with active DSP devices from the same manufacturer within its own RS-485 based control network. USB-C socket for optional direct configuration of the device via PC and control software without using a network adapter. Extensive DSP processing with a programmable EQ, Delay, X-Over and Dynamics Processor on each input and output channel. Integrated factory presets for protecting connected loudspeakers through selective multiband limiting for high-, mid- and low frequency ranges. Storage of up to 100 custom user presets is also possible. Equipped with universal power supply with Power Factor Correction and integrated microprocessor with measurement, monitoring and communication functions. Monitoring and control of supply voltage, capacity and temperature. Shutdown in the event of overload. Power supply and in-house developed technologies enable a significant increase in peak power over several seconds. An integrated Power-Up Delay enables sequential (remote) power up of multiple connected amplifiers in a rack. The amplifier has a 19“ / 2U enclosure with power switch, LED display and a magnetically attached front panel for manual, tool-free fan and filter cleaning. The amplifier’s fans are temperature controlled and are not used during idling. Ideal for mobile applications due to its low weight (9.8 kg) and for fixed installations due to its high energy efficiency. The amplifier is equipped with two programmable switching contacts (switch) and a fault contact for easy integration into the building services. Different input- and output options are available. Input options: AES/EBU (2 x Phoenix 3-pin), AES/EBU (2 x XLR), Analogue (4 x XLR) or Dante™ (2 x RJ-45 1000BASE-T Ethernet). Output options: 1 x 4-pin terminal block or 2 x Speakon connectors.
