Review: Good volume - I've eventually set my V3 amp up. I bought a pair of JBL Control One speakers and a Wiim Mini streamer. This little system sounds great already (but still warming in). There's absolutely no issue with volume levels which was a concern for me after reading a lot of reviews. The V3 amplifier could certainly drive bigger speakers but I'm good with the JBLs . Sorted. Happy. ## Features - Compact Yet Powerful: The V3 mini power amplifier combines a minimalist design with exceptional performance. With a power output of up to 600W, it can effortlessly drive 2-8Ξ© speakers, delivering impressive sound quality. Its compact size makes it suitable for various applications, from bookshelves and desktop setups to home theaters. - Audiophile-Grade Components: It features the TPA3255 high-end digital class D amp chip and utilizes premium Japanese NCC, ELNA, and German WIMA capacitors, and Japanese Sumida inductors for exceptional audio quality. With a SINAD rating of up to 88dB, an SNR of up to 110dB, and a low noise floor of only 140uV, it delivers exceptional clarity and low distortion. - Innovative Cooling: The V3 stands out with its groundbreaking heat dissipation design. Equipped with vents on the casing's top and bottom, and a whole-body heatsink design, it efficiently dissipates heat, preventing damage to components and ensuring optimal performance. - Scalable and Fun: Tailor your sound experience by swapping the stock NE5532 op-amps. V3 is compatible with a variety of 8-pin dual op-amps like Sparkos SS3602, MUSES02, OPA2604, OPA2134PA, OP249, AD827, RM4559, LM4562, LME49720HA, etc. - Worry-Free: Enjoy peace of mind with the V3 stereo amplifier. It comes with a 24-month warranty, ensuring reliable performance and customer satisfaction. - Note: The "Pre-out" level is NOT controlled by the volume control as the V3 is not an integrated amplifier, so the sound is NOT adjustable when you are connected to the "Pre-out". ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0C36S8DCT | | Best Sellers Rank | #17,660 in Electronics ( See Top 100 in Electronics ) #36 in Home Audio Amplifiers | | Brand | Fosi Audio | | Customer Reviews | 4.4 out of 5 stars 1,177 Reviews | | Manufacturer | Fosi Audio | | Mfr Part Number | V3 | | Model Number | V3 | | Unit Count | 1.0 Count | ## Images ![Fosi Audio V3 Stereo Power Amplifier Home Audio 300 Watts x2 TPA3255 Class D Mini Speaker Amp 2 Channel Audio Component Amplifier for Passive Bookshelf Tower Speakers for Desktop Home Theater - Image 1](https://m.media-amazon.com/images/I/51jOyYN2wnL.jpg) ## Questions & Answers **Q: Even if you put a 48v 11a power supply on it you would still be short of 600w, does this make any sense? is it really max 300w but miss advertised?** A: That number is misleading, it will never gets to 50watts **Q: Are each channel mono block? So I can send a differential signal to the rca inputs. Thanks!** A: https://www.amazon.com/SPRODIO-Converter-Adapter-summing-SC21/dp/B0BRZCGY29/ref=sr_1_1?keywords=stereo+to+mono+converter&qid=1684854327&sr=8-1 **Q: Total new to this. i have a pair of sony sscs5 bookshelf speakers. i don't see a way to add a subwoofer. am i correct?** A: You either need a 3 channel output device (most basic devices without a sub out are just 2 channels) that can run straight to the sub, or a subwoofer that can accept RCA, and split the RCA signal that would feed this amp before it goes to the amp with two RCA splitters or a stereo RCA splitter cable. **Q: Does the V3 come with a power supply? If so, which one?** A: It comes with a 5A, 32VDC power supply. It can put out 160 Watts of power (5A x 32V), not 32 Watts as another answer incorrectly states. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good volume *by B***H on 17 June 2025* I've eventually set my V3 amp up.
