Dante® 2CH Line Input Adapter
Balanced / Unbalanced Analog Input → Dante® Network · 5-Level Sensitivity · PoE Powered · Dante® Ultimo
This Dante® 2CH Line Input Adapter is an audio transmitter based on the Dante® Ultimo 2x2 solution. It converts two-channel balanced/unbalanced analog audio into Dante® 2CH digital audio, then transmits the audio to the receiving end through network (Dante®). Analog audio input supports 5-level sensitivity adjustment. The adapter supports local USB-C port power supply and PoE function.

Operation Controls and Functions
Device Overview — Controls & Ports
| No. | Name | Function Description |
|---|---|---|
| 1 | DANTE (PoE) port | Dante® digital audio output port, connected to the Network Switch through RJ45 line, supporting PD power supply. The green LINK LED is always on after normal connection. The yellow DATA LED is flashing when there is data transmission. |
| 2 | CH1 Knob | The 5-level sensitivity adjustment knob for analog audio input channel 1. The knob arrows indicate: 1. +24dBu, 2. +4dBu, 3. 0dBu, 4. 0dBv, 5. -10dBv. |
| 3 | CH2 Knob | The 5-level sensitivity adjustment knob for analog audio input channel 2. The knob arrows indicate: 1. +24dBu, 2. +4dBu, 3. 0dBu, 4. 0dBv, 5. -10dBv. |
| 4 | CH1 port | Balanced/unbalanced analog audio input port 1, connected to the analog audio source device. |
| 5 | CH2 port | Balanced/unbalanced analog audio input port 2, connected to the analog audio source device. |
| 6 | RESET button | Press this button to reboot the unit. |
| 7 | POWER port | USB-C port with following two functions: (1) USB-C 5V/500mA power input port. (2) Firmware update port. |
Note: The RESET button can only be used for device reboot, and device reset setting needs to be done through the Dante® Controller.
Wiring Configuration
The connection methods for balanced and unbalanced analog audio ports are as follows:
Unbalanced — RCA
Balanced — XLR
Application Example
How it works: The Dante® 2CH Line Input Adapter (this product) receives balanced/unbalanced analog audio from a Mixing Console, Media Player, or Laptop, converts it into Dante digital audio, and transmits it to the Network Switch (PoE). The switch distributes the Dante audio to a Dante® Amplifier and to a Dante® 2CH Line Output Adapter, which converts it back to analog audio for an Audio Amplifier driving Speakers.
