Dio4 is a Dante interface with 4 inputs and 4 outputs with 48v phantom power supply. It is an ideal choice for adding microphones/line inputs to Dante systems. Additionally, it has 4 line outputs that can be specified by Dante Controller software for local output of network digital audio. The front panel also allows volume control for each input audio. Dio4 is compact in size and can be installed almost anywhere. They can be installed near audio sources to minimize the interference caused by analog wiring. Dio4 has a network interface that supports 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 Category 5e or higher Ethernet 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: 1 * 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:+8dBu @ 0dB gain, -7dBu @+15dB gain, -22dBu @+30dB gain, and -37dBu @+45dB gain without 12dB fixed attenuation. When there is a fixed attenuation of 12dB, the maximum input level is 12dB higher. The total harmonic distortion of the system is<0.01%, the gain is any value, and the input signal is 3dB smaller than the maximum value. Frequency response: 20Hz-20kHz,+/-1dB
