【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.
A30Pro's THD+N is less than 0.00006%. That means A30Pro accurately restores 99.99994% of the original sound. The A30Pro is optimized for great single-ended performance using a new, specially redesigned NFCA-based circuit. Massively parallel high-performance audio operational amplifier architecture with UHGF technology provides superior DC and AC performance.
A30Pro introduces a GND/LIFT switch as a solution. For normal use, set to GND. If you experience ground loop noise, switch to LIFT to change the A30Pro's ground point from the chassis to other equipment you connect to. Ground loop noise is gone.
A30Pro is designed with sufficient quiescent current. If the headphone impedance is greater than 250 ohms, it is fully functional in Class A operation.
A30Pro offers everything in a compact body including 4-PIN-XLR, 4.4mm and 6.35mm.
D30Pro is the perfect DAC for A30Pro 4 XCS43198, which is a quad DAC sound. THD+N
