4. Use and operation steps
1) Please connect according to the prompts in the interface instructions.The device supports 12V DC and PoE power supply.
First Way：Prepare the POE switch and network cable.When the POE switch is normally powered on，connect the "Dante & POE"
interface and the POE switch with the network cable, and check that the power indicator on the panel is on；Wait about 3
seconds, and the device screen displays the device IP address information.
Second Way：Connect 220V AC power supply and interface box with 12V DC power adapter. After 220V AC power is powered on,
check the power indicator light on the panel; After waiting for about 3 seconds, the device screen displays the device's IP address.
Note: 12V DC power supply and PoE power supply cannot be
used simultaneously.
2)In the Dante audio network, the Dante Controller software
is required to route the signals that connect to the network. It
implements one-to-one, one-to-many mapping of inputs to
outputs within the Dante network.
Note: the Dante Controller software is available on
Windows 7, Windows 10, Mac OS, and OS X10. Please select
the appropriate version according to your system platform.
3)Use Sound Tune software (built-in processor) to adjust the parameters of audio signals. After the device is connected to the
local area network, open the PC software and click the "Search Device" button in the lower left corner. The IP address of the same
type of device online will be displayed. Device default Dante dynamic IP; Username: admin; Password: 123456

①Status indicator. If the green light is on, the
signal is normal. Red light signals are
abnormal.
②Phantom power switch button, phantom
voltage is 48V.
③Mute button, channel mute switch
④Analog gain adjustment gear,8 total,
including：0,1,2,3,4,5,6,7
⑤Search for the IP address of the currently
online device and display it. Right click to
select IP to modify.
⑥The driver adjusts the digital gain of the
current channel.
⑦Input button. Enter the function
adjustment of the input interface.
⑧Parametric equalization button. Enter the
parameter equalization adjustment interface
and select the channel to be adjusted.5
segment equalization: center frequency, gain,
bandwidth, all channels, reset
⑨Compressor button. Enter the compressor
adjustment interface, select the channel to be
adjusted, and adjust with the functions of
threshold, ratio, startup time, recovery time,
pass-through, reset, etc.
⑩Mixer button. Enter the mixer adjustment interface to realize
8 in 8 out matrix mixing.
⑪Diagram shows the equalization button. Enter the equalization
adjustment interface shown in the figure, select the channel
to be adjusted, and equalization adjustment of 31 segments:
narrow band, normal, wide band, frequency, gain,flatness, straight
through.
⑫Limiter button. Enter the limiter adjustment interface,
select the channel to be adjusted, and adjust with the functions of
threshold, recovery time, straight through, reset, etc.
⑬Output button. Enter the function adjustment of the output interface.
⑭Connect button. Enter the device login interface.
⑮Set button. Enter the setting interface, PC software download, upgrade,
global reset and other functions.
