CE ROHS certificates 2CH XLR analog and Dante Audio Transmission Wall Plate

Our Dante Interface products line:
- 2CH Dante AVIO:DI22,DO22,DU22
- 2CH Dante Wall Plate
- 4CH Dante BOX
- 8/16CH Dante Interface
This is our 2CH Dante Walll Plate DP22: - This product provides a signal connection between analog input and output and Dante channel, requiring PoE network power supply
- DP22 supports two sets of balanced I/O analog signals to connect to Dante system through local area network. The input interface use a two-in-one XLR to provide phantom power switch and gain adjustment function of input signal. The output interface is standard 3 Pin XLR , output balanced analog signal.

FAQ:
Question 1. Power indicator light out?
A: Check whether the POE switch is connected to the device;
B: Check whether the network connection line is normal; The way to check is to use this network cable to connect PC to the switch, whether Link light and data light flicker;
C: Equipment damage, contact customer service to get technical support;
Question 2. No signal after the microphone is connected.
A: Set the input route through the Dante Controller software.
B: Check the type of the microphone, if it is a capacitive microphone, please open the illusion power switch.
C: Improve the gain of the preamplifier circuit.
Question 3. No XLR output signal?
A:Check if the audio route has been sent to the corresponding channel through the Dante Controller software.
B: Check the normal work of the power amplifier and the horn
