----------------------------------------------------------------------
【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 offers both stereo and mono modes, flexibly adapting to diverse needs and allowing seamless mode switching. In stereo mode, it delivers a robust output of up to 180W, while in mono mode, it increases to a maximum of 235W. Pairing two ZA3 units in a mono configuration creates a powerful audio system, greatly enhancing your listening experience.
[More Connectivity] As 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-inch TRS plugs. This design minimizes interference and reduces the noise floor. The 12V trigger input connector enables synchronization. It works in conjunction with other devices, streamlining the power on/off process without requiring separate operations.
High-Quality Components: The ZA3 utilizes the TPA3255 high-end Class-D amplifier chip and premium Japanese NCC, ELNA, and German WIMA capacitors, as well as Japanese Sumida inductors, to deliver exceptional audio quality. With a maximum SNR of 106dB and a low noise floor of just 150μV, it delivers exceptional clarity and low distortion.
【Innovative Heat Dissipation Design】Based on the V3's groundbreaking heat dissipation design, we've upgraded the ZA3's cooling system by enlarging the chassis, moving the vents to the sides, and adding a dust cover to improve ventilation and deliver sustained, stable high power output.
[Scalable Enjoyment] Customize your audio experience with op-amp rolling! The ZA3 features five interchangeable op-amps for left and right channel outputs, balanced input, and subwoofer output. Try compatible DIP8 dual op-amps, such as Sparkos SS3602, MUSES02, OPA2604, OPA2134PA, OP249, AD827, RM4558, LM4562, and LME49720HA, to fine-tune your sound to perfection.
Note: 1) The power switch for this product is located on the volume knob. Press and hold the volume knob for 2 seconds to turn it on. 2) When connecting, make sure the cable plug matches the interface and is inserted properly. Check and replace any cables that may be damaged. 3) Before using this product, make sure the speaker's power matches this product's. 4) When using, turn off the Bluetooth function of other Bluetooth devices to reduce signal interference. 5) Check whether the audio source is output normally and the speaker is working properly.
Why do small sparks appear when wiring? This is a normal phenomenon. The reasons for this phenomenon are as follows: 1. Current change: When a power amplifier is operating, a certain amount of current passes through its output terminal. When a speaker contacts the power amplifier's output port, the circuit changes from an open circuit to a closed circuit. The current rises rapidly from zero to a stable value. This sudden current change generates a momentary high voltage, causing a spark. 2. Capacitor discharge: Power amplifiers usually contain energy storage components such as filter capacitors. Even after the power amplifier is turned off, these capacitors may still store a certain amount of charge. When a speaker is connected, the capacitor discharges through the speaker, forming a momentary current pulse and causing a spark.
Is treble and bass adjustment possible in RCA/XLR output mode? No. Treble and bass adjustment is only supported in headphone output mode (PO). This is because users who want to add bass when using speakers typically connect a dedicated subwoofer. Furthermore, adding treble and bass adjustment may slightly increase noise, so this function is not included in the RCA/XLR output.
For better heat dissipation, we recommend using a Fosi Audio cooling fan with your amplifier.
