Fosi Audio V3 Stereo Amplifier and P4 Mini Preamp Bundle
The Fosi Audio V3 and P4 bundle pairs a compact stereo power amplifier with a mini preamplifier to create a simple analog control-and-amplification system for passive speakers. Together, they combine the V3’s TPA3255-based 2-channel speaker power with the P4’s three RCA inputs, bass and treble controls, and front-panel source management for a more flexible desktop or home stereo setup.
Key Features
- Three RCA inputs let the P4 connect multiple line-level sources for easier system switching
- Bass and treble controls on the P4 give you more direct tonal adjustment from the front panel
- Front-panel input selection on the P4 makes day-to-day source control more convenient
- The V3 uses the TPA3255 Class D amplifier chip for compact 2-channel speaker amplification
- Rated at up to 300W x 2 on the Amazon listing, the V3 is positioned for driving passive bookshelf and tower speakers
- The compact format helps the two-piece system fit more easily on a desk or small audio rack
- Pairing a preamp and power amp in one bundle gives you source control and speaker amplification in a matched two-box setup
