TI TPA3255 Amp Chip Integrated

Enabling superior sound and ultra-low distortion across the audio band with Class-D efficiency.

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.

Advanced Heat Dissipation Design

Enhanced cooling with larger chassis, whole-body heatsink, and side ventilation with dust covers.

Swappable Op-Amps

Compatible with DIP8 dual op-amps. Roll them to get your preferred sound signature.

Separated Digital & Analog Modules

Optimized circuit board layout protects core audio modules from interference for a purer sound.

12V Trigger Sync Interface

Smooth synchronization with other devices for easy one-click power management, unifying your audio system’s operation. (Please use a 3.5mm stereo trigger cable for the trigger input on the ZA3, it must be noted that it takes several seconds for the trigger to activate the ZA3.)

Aluminum Alloy and One-Piece Molded Chassis

Delicate sandblasting and smooth beveled edges, exuding a premium, exquisite texture and high-end appeal.

Logarithmic Potentiometer

Helps to achieve a fine volume tuning to match human ear’s auditory characteristics.
