Fosi Audio ZA3 Stereo Power Amplifier TPA3255 Class D HiFi Audio Amp for Passive Bookshelf Speaker With XLR/RCA/Balanced Input
Highlight:
Dual-Mode Innovation: This new generation mini amplifier offers both stereo and mono modes, adapts flexibly to your diverse needs, allowing seamless mode switching. In stereo mode, it delivers a robust output of up to 180W, while in mono mode, the power soars to a maximum of 235W. Pair two ZA3 units in mono configuration to create a powerful audio system, significantly enhancing your listening experience.
Richer Connectivity: Debut 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 Components: The 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.
Advanced Heat Dissipation: Based on V3’s groundbreaking heat dissipation design, we 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.
Enhanced Scalable Fun: Personalize your audio experience with the op-amp rolling feature! The ZA3 stocks 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, etc. to fine-tune your sound to perfection.

Che prodotto! Lo uso per la mia scrivania e il suono fornito da questo piccolo amplificatore è semplicemente fantastico. Volume, dettaglio, alti, bassi… Tutto è lì. In passato avevo un amplificatore stereo Yamaha (400 $) e un AVR Yamaha (2000 $) che pilotavano i miei altoparlanti Bowers & Wilkins 603. Il ZA3 è migliore, e non solo un po’… Questo venditore ha anche un ottimo prezzo per questo gioiello, incluso l’alimentatore da 48 V (quello che dovresti sempre scegliere).
