The DC 5V15V 12V AD828 Stereo Preamp Power Board Pre Module is a compact stereo preamplifier board designed to be powered from a DC supply in the range of 5 to 15 volts. Built around the AD828 dual opamp, this pre module provides a dedicated frontend amplification stage for audio signals in DIY and hobby projects. Key benefits Flexible power options: operates from DC supplies in the 515V range, with 12V operation commonly used in many projects. Stereo front end: two independent channels for left and right audio signals. Easy integration: a boardlevel module intended for straightforward incorporation into enclosures or prototype builds. Reliable frontend design: utilizes the AD828 to enable stereo preamplification in a compact package. Simple signal path: designed to serve as a frontend stage between audio sources and processing stages or power amplifiers. Key attributes Functionality: stereo preamplifier power board and pre module. Compatibility: suitable for use with DC supplies in the 515V range and common linelevel audio sources. Size: compact boardlevel module suitable for compact enclosures and prototypes. Material: PCBbased module. Performance: engineered for stereo preamplification using the AD828 dual opamp. Use cases Home audio systems: connect a DAC or media player to this board, then feed the output to a power amplifier to increase signal level for listening. DIY audio projects: integrate the stereo preamp as the front end in compact guitar, keyboard, or other linelevel audio rigs. Mobile or vehicle installations: power from a 12V supply or other DC source within the 515V range to add a preamplification stage to portable audio setups.
