Fosi Audio ZA3The next generation balanced dual-mode Class-D power amplifier. Fosi Audio's first amplifier supporting both stereo and mono modes.Amplifying Your Voice, Shaping Our InnovationAt Fosi Audio, behind every innovation, there's a story. The birth of the ZA3 amplifier is just such a story, centered around our users. After the launch of the V3 amplifier, we gathered innumerable feedback from passionate audiophiles. They expressed a desire for us to develop an even better amplifier based on V3.TI TPA3255 Amp Chip IntegratedEnabling superior sound and ultra-low distortion across the audio band with Class-D efficiency.Swappable Op-AmpsCompatible with DIP8 dual op-amps. Roll them to get your preferred sound signature.Advanced Heat Dissipation DesignBased on V3's groundbreaking heat dissipation design, Fosi Audio upgraded ZA3's cooling system by featuring a larger chassis, moving vents to the sides, and adding dust covers to achieve better ventilation for a sustained and stable high power output.Separated Digital and Analog ModulesOptimized circuit board layout protects core audio modules from interference for a purer sound.Richer ConnectivityDebut amplifier with balanced input and trigger in, the ZA3 features a balanced combo audio signal input connector supporting both XLR and 1/4" TRS plugs. This design minimizes interference and reduces noise floor. The 12V trigger-in connector enables synchronization with other devices, streamlining the process of turning on/off without individual operations.Audiophile Grade ComponentsThe ZA3 features the TPA3255 high-end 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 89dB, an SNR of up to 106dB, and a low noise floor of only 150μV, it delivers exceptional clarity and low distortion.
