VU Meter Driver PCB Completed Board Stereo for 110898091550
The VU Meter Driver PCB is a specialized circuit board designed to facilitate the connection and operation of two VU meters in audio applications, specifically tailored for stereo audio amplifiers. This board operates within a power voltage range of AC 20V to AC 26V, ensuring compatibility with a variety of audio equipment while maintaining optimal performance.
The physical dimensions of the PCB are 52 mm in width, 67 mm in length, and 32 mm in height, making it compact enough for integration into various audio setups without requiring excessive space. The board is equipped to handle VU meters with current ratings ranging from 100 µA to 500 µA, allowing for flexibility depending on the specific requirements of the audio system.
One of the notable features of this VU Meter Driver PCB is its user-friendly design, which eliminates the need for manual adjustments when using the 500 µA VU meters. For other types of VU meters, users may need to perform some adjustments to ensure accurate readings. The default input configuration is set to LOW-0-LOW, which connects to two low-level input terminals intended for audio output from a CD player, with connections designated for left, ground, and right channels.
For applications where the VU Meter Driver PCB is connected to the speaker output terminals of an amplifier, it is essential to switch to a HIGH-0-HIGH configuration. This adjustment requires soldering specific resistors, namely 1 ohm and 9 ohms, to the designated points on the PCB to ensure proper signal processing and VU meter functionality.
Overall, this VU Meter Driver PCB represents an efficient solution for monitoring audio levels in stereo systems, providing an essential tool for audio engineers and enthusiasts seeking to enhance their audio experience through visual level indication.VU Meter Driver PCB Completed Board Stereo for Two VU Meters Audio Amplifier.
