ProTone A44D

4-channel power amplifier with dsp

ProTone A44D is a 4-channel power amplifier with embedded DSP. An amplifier is the same as ProTone 7005. Program control can be provided by touch screen on the front board or remotely by PC with control program via Ethernet connection. The key feature of ProTone A44D is the output, which transmits processor’s signal to other amplifiers ProTone 7005 thus they are combined into one device. ProTone A44D has two analog and two digital AES/EBU inputs.

There are two symmetric analog inputs, two through XLR outputs, 2-channel digital input and through output AES (XLR), two Ethernet slots (connectors Ethercon) for linking to control PC, inputs for loudspeaker systems, input for power cable on the back board.
