Fosi Audio V3 MONO Combo – Pair of Monoblocks - 48V10A

Product detailed description

The Fosi Audio V3 Mono set brings two separate monoblock amplifiers in one package, complemented by a single powerful power supply and a DC filtr for the cleanest possible signal. It's the ideal solution for listeners looking for truly separate channels, quiet operation and excellent dynamics in a home hi-fi system.

Each monoblock uses top-class Class D technology based on the Texas Instruments TPA3255. The result is precise, detailed and energy-efficient sound that can handle even more demanding speakers. A robust metal chassis with optimised cooling and high-quality audio components guarantees long-term stability and high performance.

Wide connection options

Each monoblock offers RCA, XLR or TRS inputs. Inputs are selected with a simple switch on the front panel. Thanks to independent amplification of both channels, you get better separation, a wider soundstage and more control at higher volumes.

Stereo power without compromise

The twin pack is the ideal choice for building a high-quality stereo system without the complexity of multiple power supplies. A single power supply with a DC filtr ensures stable, quiet operation, while two separate monoblocks deliver truly independent channels – a solution once reserved for far more expensive audio setups.

Note on the current version: Newer production units of the Fosi Audio V3 Mono use a switchable 19 dB / 25 dB gain for the RCA input. Earlier units used 25 dB / 31 dB. The manufacturer reduced the gain in the new revision to ensure a more stable output, safer operation and a longer amplifier lifespan.
