AJMRTC TA7318P VU Meter Driver PCB Board, AC/DC 1215V DB Level Meter FrontEnd Drive Module for Tube Amplifier, Audio Signal Indicator Driver Kit for HiFi Vacuum Amp DIY Audio Modification Projects

AJMRTC TA7318P VU meter driver PCB module is a professional levelmeter drive board designed for analog audio equipment. Based on TA7318P dedicated VU driving IC, it processes input audio signal and outputs corresponding drive signal to push analog DB VU meter pointer, realizing realtime audio volume level visualization. It supports both AC and DC 1215V power supply, which matches common power supply conditions of vacuum tube amplifiers. Serving as frontend signal processing unit, this module simplifies peripheral circuit design for VU meter installation on tube amplifiers. It brings classic retro meter display effect for homemade or renovated HiFi audio systems. This bare PCB driver module needs to be matched with analog VU meter and audio signal source. Users should complete signalinput, powersupply and meteroutput wiring strictly following pin definition. It is widely applied in vacuum tube amplifier modification, vintage audio restoration and analog audio DIY projects.
