Features:
- With dedicated network Karaoke USB sound card chip, the sound is clearer and background noise is less. You can specify YY to use USB sound for connection, and the sound card that comes with your computer can be used to watch movies and play music, without affecting each other.
- The dedicated USB chip detects the SQL signal of the station, and uses the SQL signal to control the YY software forwarding. Replaces the original VOX trigger. It avoids the wrong voltage induced by the connecting cable to trigger YY forwarding. The anti-interference ability has reached a super level.
- Professional sound detection chip. Detect the sound of the computer speaker and control the PTT, so that the handheld transceiver and relay forwards the sound of the computer speaker.
- The computer side controls the PTT of handheld transceiver, and uses optocouplers for photoelectric isolation to ensure that the computer-side noise will not cross up to the walkie talkie.
- Use high quality isolation transformer. Isolate USB sound card audio and handheld transceiver audio to further reduce interference.
- Use magnetic beads to isolate power interference and high-frequency radiation.
- PCB using high quality material: FR4 double sided PCB with fire rating 94V0. All components on the board are high-quality SMD components.
- Its all-metal shell can isolate all spatial interference.
- Support for ASL.

Package Included:
- 1 x Main Unit
- 2 x USB Cables
- 1 x 6-pin Data Cable
- 1 x 6-pin to 16-pin Conversion Board

Note:
- Since the new version of "ZELLO" has officially changed the intercom control mode, all R1 reception tests of current and previous need to be set to use "VOX", or install the software for MouseChange to switch mouse detection to keyboard F7 control.

Attention:
- It is only suitable for people with hands-on ability, to connect relay, mobile radio and handheld transceiver.
- If this YY interface board is used to connect a relay, the relay needs to turn off the delay function. Otherwise, it will cause text to be missing when it is just connected. However, repeated echoes may occur. This is because the voice-controlled PTT principle determines that the relay cannot be turned on and delayed. It is not a defect of this interface board.
- The metal shell is customized in small quantities. Its screw hole has a certain process error, but the appearance is very good, and the edge does not scratch the hand. Please make sure that you don't mind before purchasing. Thank you!
