Programmable audio controller with PT2314 sound processor What it does and why you need it Provides precise control of volume, treble and bass, and includes a mute function so you can quickly silence output without changing settings. Lets you switch between up to four stereo sources and route audio to two outputs, simplifying input management for systems with multiple devices. Uses the I2C bus so every function can be programmed and controlled remotely by a host controller, enabling automated or software-driven audio control. Key features Audio control: volume, treble, bass adjustment and mute functionality. Inputs and outputs: supports four sets of stereo inputs and two outputs for flexible routing. Control interface: full I2C support for programming and remote control of all functions. Sound processing: integrated PT2314 chip for clear tone shaping and reliable performance. Compatibility and integration Works with standard line‑level stereo sources such as CD players, media players, tuners, and preamps. Integrates with I2C-capable controllers and systems (for example microcontrollers or single-board computers) to enable automated control and custom user interfaces. Designed for straightforward integration into desktop, embedded, or small audio systems that need compact, programmable tone and input control. Performance and reliability The PT2314 integrated chip provides consistent, low-noise tone control and switching behavior across channels. I2C programmability allows repeatable configurations and remote muting or level adjustments without manual intervention. Practical applications Home audio preamp: Consolidate multiple source components, switch inputs, and fine-tune treble/bass and volume from a single control system. Custom audio projects: Use an Arduino, Raspberry Pi, or other I2C host to create a programmable front-end for DIY amplifiers, media players, or smart audio devices. Commercial or kiosk installations: Manage multiple stereo sources and provide remote mute and level control for point-of-sale, information kiosks, or small meeting rooms. What to expect A programmable, PT2314-based audio control solution that simplifies multi-source management, delivers essential tone and volume controls, and integrates with I2C host controllers for automated operation.
