Software Introduction
PC Software Operation Introduction
Computer Configuration Requirements: Screen resolution higher than 1280 x 768, otherwise the software UI is incomplete. Only suitable for Windows operating system laptops, desktops, and pads.
1. Menu Editing Area
Main functions: Opt, Save, Load.
- Save/Load: Click the Save or Load pop-up window to load a scene from your computer, save the current configuration as a scene on your computer, load the whole machine scene, or save the whole machine scene.
- Options: Click on "Opt" to select language (Chinese and English), Factory Reset, Noise gate threshold, Firmware Version, and Software Version.
2. Function Editing Area
- Input Selection: The CS810 supports digital and analog signal split-screen input. Select through High priority and Low priority options.
- Routing Settings: Click "Routing Settings" to enter Mixing Settings. This interface allows for routing audio signals between inputs and outputs.
3. Main Volume and Software Connection Editing Area
- Main Volume Adjustment: The adjustment range is from OFF to 6dB, with steps down to -59.9dB. Click the speaker button to mute the main volume.
- Channel Linking: Options to link channels for stereo or other configurations are available.
5. Channel Delay Editing Area
This area allows for the adjustment of channel delay parameters. Visual representations of the car's audio system are shown, with delay values for different channels.
6. Channel Divider Editing Area
Main Function Setup: Channel High & Low Pass Filter Setup. Adjustable parameters include Filter Type, Frequency point, and Q Value (Gradient or Slope).
7. Equalizer Editing Area
- Reset EQ: Restores all equalizer parameters to the original pass-through mode (frequency, Q value, and gain are reset to initial values).
- Restore EQ: Switches between the currently designed equalizer state parameters and the pass-through mode (gain of all equalization points is reset to 0 dB, frequency and value remain unchanged).
- PEQ Mode: Click PEQ Mode to switch to GEQ Mode. In GEQ Mode, the Q value and frequency cannot be adjusted.
8. Channel EQ Editing Area
Main function configuration: Equilibrium design of current output channel, 31-band equalization is adjustable for frequency, Q value (response bandwidth), and gain (increasing or decreasing the frequency response amplitude near the frequency point).
