【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. Dual-mode innovation: This new generation mini amplifier provides both stereo and mono modes, flexibly adapting to diverse needs and allowing seamless mode switching. It offers a robust output of up to 180W in stereo mode, while it rises to a maximum of 235W in mono mode. Pairing two ZA3 units in a mono configuration creates a powerful audio system that greatly improves your listening experience. More connectivity: An audio amplifier with balanced and trigger inputs, the ZA3 features a balanced combo audio signal input connector that supports both XLR and 1/4" TRS plugs. This design minimizes interference and reduces the noise floor. A 12V trigger input connector allows synchronization. Works with other devices to streamline the power on/off process without separate operations. High-quality components: ZA3 is equipped with a TPA3255 high-end Class-D amplifier chip and utilizes premium Japanese NCC, ELNA, German WIMA capacitors, and Japanese Sumida inductors for outstanding audio quality. Up to 106dB SNR and low noise floor of just 150μV deliver exceptional clarity and low distortion. Innovative heat dissipation design: Based on the V3's breakthrough heat dissipation design, we upgraded the ZA3's cooling system by enlarging the chassis, moving the vents to the side, and adding a dust cover to improve airflow and deliver sustained and stable high power output. Scalable fun: Customize your audio experience with op amp rolling! The ZA3 features 5 interchangeable op amps for left and right channel outputs, balanced inputs, and subwoofer outputs. Try compatible DIP8 dual op amps like Sparkos SS3602, MUSES02, OPA2604, OPA2134PA, OP249, AD827, RM4558, LM4562, LME49720HA and more to fine-tune your sound to perfection.
