1pc PT2399 Digital Microphone/Amplifier Board — Plate Reverb Preamplifier (7V–24V) Why you need this board Add studiostyle plate reverb and clean preamplification to a microphone signal without complex gear. The PT2399based module gives smooth reverb tails and naturalsounding ambience to voices and instruments. Solve flat or dry vocals in karaoke, home studio, or live sound with a compact, boardlevel solution that integrates directly into existing audio chains. Useful for DIY repairs, upgrades, or custom audio projects where a small, dedicated reverb/preamp is required. Key benefits Simple integration: power the board and connect a microphone input and an amp/mixer output for instant reverb and preamp functionality. Improved vocal presence: the reverb effect enhances perceived space and depth, helping vocals sit better in a mix or live performance. Compact and convenient: a small PCB module that keeps signal routing and assembly straightforward for hobbyists and technicians. Main attributes Chipset: PT2399 digital reverberation IC for platestyle reverb processing. Functionality: digital plate reverb plus preamplifier/reverberator for microphone applications. Power supply: operates from 7V up to 24V DC (observe correct polarity and rated supply). Quantity: 1pc module per package. Form factor: boardlevel module designed for easy mounting and wiring into audio projects or equipment. Performance and compatibility Designed to work with microphone and amplifier systems commonly used in karaoke, public address, and home studio setups. Produces platestyle reverb effects suitable for vocals and many instruments; pairs well with mixers, amplifiers, and preamps. Intended for applications where a compact, PCBmounted reverberator/preamp is required. Typical use cases Karaoke systems: add smooth reverb and mild preamplification to handheld or mounted microphones to improve vocal character and presence during performances. Home studio and podcasting: give dry vocal recordings a professional ambience without heavy outboard gear; useful for directtomixer setups or simple recording chains. DIY audio projects and repairs: integrate into custom microphone preamps, small PA systems, or to /upgrade existing reverberation circuits. Basic connection guidance Provide DC power within the specified 7V–24V range, respecting polarity and stable supply. Connect microphone input to the board input and run the board output to an amplifier, mixer, or recording interface. Adjust gain and reverb parameters as available on the module to suit the source and desired effect.
