## Questions & Answers

A: 1. Computer: Settings > Sound > Fosi Audio, and change the left and right balance levels. 2. iPhone: Settings > Accessibility >Audio/Visual> Balance, slide horizontal slider to the left or right to adjust the balance.

**Q: Do I need a pair of the same opamps or can they be swapped in different combinations?**
A: If your OP-AMP is pin-to-pin (P2P), meaning the pins and functions of the two OP-AMPs are exactly the same, so you can directly install one model at a time. However, there might be a difference in sound quality or sound volume on one side.

**Q: What is a difference between two versions of V3 amp - 32v and 48v?**
A: Compared to a 32V power supply, a 48V power supply can enhance the amplifier's power output, providing more headroom to prevent distortion and enabling it to drive larger, more powerful, or higher-impedance speakers.

**Q: Can the V3 amplifier be bridged to work as a monoblock amplifier?**
A: It doesn't support bridge mode.

**Q: Only one channel has a sound or unbalanced output?**
A: Cross-check left & right speakers, speaker wires, input cable eliminating either speaker or wiring. Please ensure that the speaker wire is correctly connected and not bent.
