Onboard PT2314 sound-quality processor module — compact PCB module that gives precise, programmable audio control for integration into audio systems and DIY projects. Key benefits Centralized audio control: combines input selection and tone/volume management on a single board, reducing wiring and component count. Flexible source handling: supports four stereo inputs so you can connect multiple players, tuners, or line-level sources without external switchers. Simple integration and automation: full control via the I2C bus lets microcontrollers or control systems set volume, treble, bass, mute, and input selection programmatically. Reliable sound processing: uses the PT2314 onboard chip to deliver consistent, repeatable tone and level adjustments. What it does (core functions) Onboard PT2314 Sound Quality Processor Chip for tone and level control. Four sets of stereo inputs (A/B/C/D). Dual-channel (stereo) outputs. Volume control, treble and bass control, mute, and related audio functions. I2C bus support to program and automate all functions. Compatibility and attributes Function: Input selection, tone shaping (treble/bass), volume control, mute; all functions addressable via I2C. Compatibility: Designed for integration with line-level audio sources and devices or systems that can communicate over an I2C interface. Works with amplifiers, preamplifiers, or audio processors that accept stereo line inputs. Size and form factor: Compact PCB module suitable for mounting inside enclosures or equipment racks (module form factor; check physical dimensions before final mounting). Material and construction: Standard PCB electronics construction with the PT2314 chip and supporting components on board. Performance: Digital control of tone and level via PT2314 ensures precise, repeatable adjustments and straightforward software control. Practical applications (examples) Home audio preamp or multi-source stereo system: Use the module to switch between four stereo sources and control tone and volume from a single microcontroller or front panel controller over I2C. DIY amplifier or hi‑fi projects: Add programmable volume, treble, bass, and mute functions to a custom amplifier or integrated system without designing discrete tone circuits. Embedded audio systems and kiosks: Integrate into commercial or industrial devices that need remote or automated audio level and tone control via an I2C-capable controller. Technical notes All processing and control functions are provided by the onboard PT2314 chip. Full function programming requires an I2C controller to send commands and set parameters. Confirm connector types and physical mounting requirements against your enclosure and wiring plan before installation.
