summary Dio4 is a Dante interface with 4 inputs and 4 outputs with 48V phantom power supply. If you need to add a microphone/line input to the Dante system, it is an ideal choice, and there are also 4 line outputs. The Dante Controller software can specify 4 network digital audio for local output, and the front panel can also control the volume of each input audio. The Dio4 is compact and can be installed almost anywhere. It can be installed near the sound source to minimize analog wiring that is prone to interference. Dio4 has three network interfaces that can support Dante daisy chain connections. Dante connectivity simplifies the infrastructure cabling of the system, allowing multiple Dio4 units to be connected to a network switch using a single Category 5 or more network cable. Dio4 is powered by an external 12VDC power supply. The input output routing of Dio4 is configured by Dante Controller software. Specification parameters Network interface: 3 * RJ45, Microphone/Line Input Type: COMBO interface, balanced XLR/6.35 input compatible Input impedance:>1800 ohms, gain set to any value Equivalent input noise: -115dBu (+45dB gain) Maximum input level: without 12dB fixed attenuation,+8dBu @ 0dB gain, -7dBu @+15dB gain, -22dBu @+30dB gain, and -37dBu @+45dB gain. When there is a fixed attenuation of 12dB, the maximum input level is 12dB higher Total harmonic distortion of the system:<0.01%, the gain is any value, and the input signal is 3dB smaller than the maximum value Frequency response: 20Hz -20kHz,+/-1dB...
