Connecting Instruction
Instruction of Mobilephone Livestreaming
- Use a Type B A/M USB Data Cable to connect to the computer;
- Use the 3.5mm audio cable equipped to connect the product with the mobile phone;
- Insert the headset into the “headphone” jack;
- Computer to play the accompaniment, and adjust the “microphone” volume and “monitor” volume, so that the microphone and accompaniment volume match;
- Open the mobile phone livestreaming APP, adjust the total volume of the livestreaming to a suitable level, you can enjoy the fantastic livestreaming experience.
Control Panel Instruction
- HW1/2 (MIC), the input channel of the Audio Interface driver, the audio comes from the microphone input of the hardware.
- HW3/4 (LINE IN), the input channel of the Audio Interface driver, the audio comes from the 3.5mm accompaniment input of the hardware and the mixing of the instrument input.
- Out1/2, the input channel of the Audio Interface driver, the audio data comes from the system playback device AI2C 1/2.
- Out 3/4, the input channel of the Audio Interface driver, the audio data comes from the system playback device AI2C 3/4.
- Virtual 1/2, the input channel of the Audio Interface driver, the audio data comes from the system playback device AI2C Virtual 1/2.
- Virtual 3/4, the input channel of the Audio Interface driver, the audio data comes from the system playback device AI2C Virtual 3/4.
- HW1/2 (HP), the output channel of the Audio Interface driver, output to the earphone and LINE OUTPUTS interface on the hardware device.
- HW 3/4 (Phone), the output channel of the Audio Interface driver, output to the mobile phone live interface on the hardware device.
- In 1/2, the output channel of the Audio Interface driver, output to the system recording device AI2C 1/2.
- In 3/4, the output channel of the Audio Interface driver, output to the system recording device AI2C 3/4.
- Virtual 1/2, the output channel of the Audio Interface driver, output to the system recording device AI2C Virtual 1/2.

Driver settings
- Sound card sampling rate setting;
- ASIO cache setting, the smaller the ASIO cache setting, the higher the requirements for computer performance. When the ASIO buffer is too small, the computer cannot process the audio data in time, and noise will appear. At this time, a larger ASIO buffer should be set;
- Safe mode. After the safe mode is turned on, the requirements for computer performance can be appropriately reduced, but at the same time it will also increase the delay of ASIO;
Compatible System

- Window 7(64-bit)
- Window 8(32-bit)
- Window 8(64-bit)
- Window 8.1(32-bit)
- Window 8.1(64-bit)

Troubleshooting
- No sound from the microphone
- Please check physical connection of the microphone;
- Please check whether the 48V phantom power is turned on (in the case of 48V condenser microphones);
- Please check if the headphone and microphone volume knobs are in place;
- Please check whether the volume of the driver panel is adjusted too low or muted.
- Howling from the microphone
- Please check whether the microphone is directly facing the speaker;
- Please check whether the microphone is too close to the speaker, and keep the distance between the microphone and the speaker at least 1.5 meters;
- Please check whether the microphone gain and earphone gain are too large.
- The microphone is noisy
- Please check if the microphone is connected well, or please re-plug it;
- Please check if the distance between the microphone and the lips is too close, the distance between the lips and the microphone should be kept at 10-20 mm or at a 45 degree angle, better results can be obtained;
- Please check whether the microphone gain is too large, causing the microphone to pick up too sensitively;
- Please check whether there are noisy noise sources in the surrounding environment that affect the microphone pickup;
- Please check whether there is a “router” or other large electrical equipment causing interference in the surrounding environment.
