Inputs and Outputs
The input and output selections that are offered is an important factor when comparing two amplifiers. Here you can find how the I/O selections of the Fosi Audio V3 Mono and Fosi Audio ZA3 differs from each other.

Fosi Audio ZA3 Inputs
- Total Number of Analog Inputs: 2
- RCA Line Input
- XLR Input Port
Balanced connections
Both have balanced XLR connections. A balanced cable carries the signal twice, on two conductors of opposite polarity. Interference picked up along the way lands on both equally and cancels when the two are recombined at the far end, so the longer the cable run and the noisier the surroundings, the more it is worth. Whether it also yields more power depends on how the amplifier is built inside - some are balanced end to end, others convert to single-ended internally and deliver the same either way.
