Control Panel Instruction
Driver settings
1. Sound card sampling rate setting;
2. 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;
3. 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;
1. HW1/2 (MIC), the input channel of the Audio Interface driver, the audio comes from the microphone
input of the hardware.
2. 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.
3. Out1/2, the input channel of the Audio Interface driver, the audio data comes from the system
playback device AI2C 1/2.
4. Out 3/4, the input channel of the Audio Interface driver, the audio data comes from the system
playback device AI2C 3/4.
5. Virtual 1/2, the input channel of the Audio Interface driver, the audio data comes from the system
playback device AI2C Virtual 1/2.
6. Virtual 3/4, the input channel of the Audio Interface driver, the audio data comes from the system
playback device AI2C Virtual 3/4.
7. HW1/2 (HP), the output channel of the Audio Interface driver, output to the earphone and LINE
OUTPUTS interface on the hardware device.
8. HW 3/4 (Phone), the output channel of the Audio Interface driver, output to the mobile phone live
interface on the hardware device.
9.In 1/2, the output channel of the Audio Interface driver, output to the system recording device AI2C
1/2.
10.In 3/4, the output channel of the Audio Interface driver, output to the system recording device AI2C
3/4.
11.Virtual 1/2, the output channel of the Audio Interface driver, output to the system recording device
AI2C Virtual 1/2.
12. Virtual 3/4, the output channel of the Audio Interface driver, output to the system recording device
AI2C Virtual 3/4.

Maintenance
1. Use in low temperature and dry environment
Keep this product in a dry environment, pay attention to moisture and static electricity, and avoid use
in high temperature and high humidity environments;
2. Regularly clean and maintain it
It is recommended to conduct professional cleaning and maintenance on a regular basis;
3. Storage conditions
If not used for a long time, this product must be stored in a dry environment;
A moisture-proof storage box with temperature and humidity adjustment functions is preferred.
Troubleshooting
1. 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.
2. 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.
3. 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.
