I2C-Controlled Stereo Audio Module with PT2314 — Key Benefits and Features What this module does for you Provides digital control of basic audio functions via the I2C bus, enabling easy integration with microcontrollers or single-board computers. Lets you switch and process multiple sources with four stereo inputs and a two-channel stereo output, simplifying source management for small audio systems. Uses the integrated PT2314 chipset for reliable audio processing and consistent sound quality. Offers direct control of volume, treble, bass and mute, so you can implement full user or automated control without extra analog circuitry. Why customers choose this module Simplifies system design: I2C control centralizes audio settings and removes the need for multiple analog potentiometers or manual switching. Flexible source handling: four stereo inputs let you connect multiple devices (e.g., media player, tuner, microphone preamp, and another line source) and route them to a single stereo output. Consistent audio quality: the PT2314 chipset delivers proven tone control and level adjustment functions in one compact solution. Easy automation: volume, tone and mute can be adjusted programmatically for use in smart systems, automated kiosks, or remote-control applications. Key specifications and functions Control interface: I2C bus for programming all functions. Inputs/outputs: four stereo inputs; two-channel (stereo) output. Audio processing: integrated PT2314 chipset. Supported controls: volume, treble, bass, mute, and related tone/level functions accessible via I2C. Compatibility and integration Works with any I2C-compatible host controller or system that can act as an I2C master. Suitable for integration into DIY projects, embedded systems, or retrofit audio equipment where digital control of volume and tone is required. No additional analog control chips required for the listed functions; uses the PT2314 for tone and level control. Typical use scenarios DIY stereo preamplifier or home audio controller: connect multiple source devices and control volume and tone digitally from a microcontroller or control panel. Embedded audio in kiosks, retail displays or industrial HMIs: program mute, volume and tone changes based on user interaction or system events. Small public-address or multimedia installations: switch between input sources and manage output level and tone centrally without complex wiring. What to expect in practice Straightforward I2C commands let you program and recall volume and tone settings. Four-input switching reduces the need for external multiplexers or manual input switching. Integrated PT2314 means tone controls (treble/bass) and mute are hardware-supported for stable, repeatable audio behavior. If you need digital, compact, and proven tone/volume control for a stereo system with multiple inputs, this I2C-controlled module with the PT2314 chipset provides a practical, integration-friendly solution.
