DATEQ DDA-43DT AMPLIFIER CLASS D DSP NETWORK

SKU 953.630DQ Categories , , Brand:

Description

The DATEQ DDA-43DT is a four-channel Class D power amplifier combining Dante network audio, analogue inputs and integrated DSP. It delivers 450 W per channel into 4 Ω or 300 W per channel into 8 Ω, with bridged operation supporting 70 V and 100 V speaker systems. Selectable input priorities provide backup switching between analogue and Dante sources. FIR processing and adjustable output limits help installers configure the amplifier for different loudspeaker systems. An IPS colour display provides real-time monitoring of power, current, voltage, temperature and impedance. MusicAllDSP software allows configuration and control of multiple amplifiers through network, USB or serial connections.
