Interfaces
- Power LED: ▪ Steady on: The unit is working normally.
▪ Slow flash at 4Hz: The Web GUI operation is in standby mode.
▪ Fast flash at 1Hz: There is no signal input, and the unit will enter the standby mode within the set duration. - ID (show me) LED: This LED indicates the presence of the product. It can be controlled through Web GUI or API command. For example, when selecting the “On” option for “DANTE Identification” on the System page of the Web GUI, the ID (show me) LED on the front panel will flash, so that you can find the corresponding machine in the system.
- LINE/DANTE LED: Input signal source indicators. When the DANTE or LINE IN port is selected as the signal input channel, the corresponding green LINE/DANTE LED is on.
Note: The DANTE port is the signal input channel by default. - VOL LED: The main audio volume of the system is displayed in five green segments, with each segment corresponding to 20% of the volume. 50% of the main audio volume is displayed by default after system initialization.
Note: The audio volume can be controlled through Web GUI or API command. - SIGNAL L/R LEDs: Left and right channel signal indicators of the stereo audio. When there is stereo audio signal, the LEDs will be on.
- PROTECT LED: When the machine is protected by overtemperature, overcurrent or overvoltage, the PROTECT LED is on.

TRG: T trigger signal input port, effective at high level. When this port is connected to a 5V/12V trigger voltage, the amplifier will be mute. After trigger is disconnected, the amplifier can output audio normally. - RESET button: Press and hold this button for 5 seconds to restore to factory default settings.
- SPEAKER switch: Speaker high-low resistance switch, used to switch among Lo-Z (4Ω/8Ω), Hi-70V and Hi-100V.
- DANTE port: Dante audio input and output port, using dynamic IP by default.
- LINE IN port: Balanced stereo audio input port, with a Max input level of 2Vrms.
- LINE OUT port: Balanced stereo audio output port, with a Max output level of 2Vrms.
- 4/8Ω OUT port: 4/8Ω speaker output port. When this port is connected to a 4/8Ω speaker and the SPEAKER switch is dialed to 4/8Ω, the audio will be output from this port normally.
- 70/100V OUT port: 70/100V speaker output port. When this port is connected to a 70/ 100V speaker and the SPEAKER switch is dialed to 70/100V, the audio will be output from this port normally.
