Key benefits Precise, real-time control of audio: adjust overall volume, treble and bass, and mute instantly to match listening conditions or compensate for room acoustics. Flexible source management: four independent stereo inputs let you switch between multiple audio sources without rewiring. Easy integration and automation: full control over every function via the I2C bus enables remote control, preset recall, or MCU-driven audio management. Reliable sound processing: the onboard PT2314 audio processor delivers consistent tone shaping and level control suitable for professional and consumer applications. What it does (features and functions) Volume control, treble and bass adjustment, and mute function. Four sets of stereo inputs and two-channel (stereo) outputs. I2C bus support for programming and remote control of all functions. Onboard PT2314 audio-quality processor chip to manage tone and balance. Why customers need it Simplifies multi-source audio systems by centralizing level and tone control in one module. Enables automated or remote audio control when used with microcontrollers or control systems that support I2C. Improves sound consistency across sources by applying the same tone-shaping and volume rules through a single processor chip. Compatibility and integration Works with devices and systems that provide stereo audio signals and an I2C control interface. Suitable for integration into DIY audio projects, embedded systems, or equipment that requires programmatic audio control. No special drivers required for the PT2314 functions; control is performed through standard I2C commands. Performance and reliability Tone and volume handled by the PT2314 onboard chip to maintain stable, predictable audio behavior. Two-channel outputs support standard stereo setups without additional conversion. Typical use scenarios Home audio control panel: integrate into a multi-source home audio setup to switch inputs and adjust tone and volume from a central controller or wall-mounted touch panel. Embedded/DIY projects: add programmatic volume and tone control to hobby or industrial boards by connecting the module to a microcontroller over I2C. Commercial audio systems and kiosks: manage background music sources and remotely mute or adjust levels from a building automation system. What you get A functional audio control module featuring volume, treble, bass, mute, four stereo inputs, two-channel outputs, I2C programmability, and an onboard PT2314 audio processor — designed to simplify integration and deliver consistent audio control.
