Fosi Audio ZA3+48V/5A

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

Enhanced connectivity: The ZA3 is the first amplifier with a balanced input and trigger-in, featuring 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 allows synchronization with other devices, streamlining power on/off without manual operation.

Audio-grade components: The ZA3 is equipped with the high-end TPA3255 Class D amplifier chip and uses premium Japanese NCC and ELNA capacitors, German WIMA capacitors, and Japanese Sumida inductors for exceptional sound quality. With a SINAD rating up to 89 dB, SNR up to 106 dB, and a low noise floor of just 150 μV, it delivers outstanding clarity and minimal distortion.

Advanced heat dissipation: Building on the groundbreaking thermal design of the V3, the ZA3’s cooling system has been upgraded with a larger chassis, side ventilation openings, and dust covers for improved airflow, ensuring consistent and stable high output power.

Enhanced scalable functionality: Personalize your audio experience with the op-amp rolling feature! The ZA3 has five swappable 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, and others to fine-tune your sound to perfection.
