Fosi Audio ZA3+48V/5A

Dual-Mode Innovation: This new-generation mini amplifier offers both stereo and mono modes, flexibly adapts to your diverse needs, and enables seamless switching between modes. In stereo mode, it delivers a robust power output of up to 180 W, while in mono mode, the power output increases to a maximum of 235 W. Pair two ZA3 units in a mono configuration to create a powerful audio system, significantly enhancing your listening experience.

Better connectivity: The ZA3 is the first amplifier with a balanced input and trigger-in, and features a balanced combo audio input that supports both XLR and 1/4" TRS plugs. This design minimizes interference and reduces noise. The 12V trigger-in connector enables synchronization with other devices, streamlining the power-on and power-off processes without the need for individual actions.

Audio-Grade Components: The ZA3 features the TPA3255 high-end Class D amplifier chip and utilizes high-quality Japanese NCC and ELNA capacitors, German WIMA capacitors, and Japanese Sumida inductors to deliver exceptional sound quality. With a SINAD rating of up to 89 dB, an SNR of up to 106 dB, and a low noise floor of just 150 μV, it delivers exceptional clarity and low distortion.

Advanced Heat Dissipation: Building on the V3’s groundbreaking heat dissipation design, we’ve upgraded the ZA3’s cooling system with a larger chassis, side vents, and dust covers to improve ventilation and ensure sustained, stable high output power.

Enhanced scalable functionality: personalize your audio experience with the op-amp rolling feature! The ZA3 has five interchangeable op-amps for left and right channel outputs, balanced input, and subwoofer output. Experiment with compatible DIP8 dual op-amps such as Sparkos SS3602, MUSES02, OPA2604, OPA2134PA, OP249, AD827, RM4558, LM4562, LME49720HA, etc., to fine-tune your sound to perfection.
