【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.

[About clocks that synchronize time via radio waves] The function of clocks that synchronize time via radio waves only works in the Japanese area. Please be careful.

You can. [Headphone Amplifier] Tone2 Pro is equipped with a 3-stage amplification system for 3.5mm single-ended and 4.4mm balanced outputs. Adopts TI's OPA1612 operational amplifier to achieve excellent sound quality and distortion characteristics. [High Performance] Tone2Pro continues to use the ES9038Q2MDAC chip from ESS, known for Tone1. Our community is happy to have eliminated the ESS hump. [Size] Depth 120mm Width 121mm Height 30mm (H) Khadas Tone 2 Pro USB DAC and Headphone Amplifier with Balanced RCA Hardware MQA Decoding The Tone2 Pro is a second generation toneboard. It incorporates various user feedback from our first generation product, Tone1. The ESS ES9038Q2M DAC is paired with four powerful OPA1612 operational amplifiers and three buffer amplifiers. This three-stage amplification path allows the Tone2 Pro to drive a wide range of demanding audiophile-grade headphones with impedances up to 150 ohms. Other additional features on the Tone2 Pro include a 4.4mm balanced headphone jack in addition to the standard 3.5mm single-ended jack. Two USB-C ports allow you to connect a 5V linear power supply to the second USB-C port while using the first USB-C data for superior power noise isolation. Finally, we added the industry's first balanced RCA line out. These new RCA ports have three signal pins instead of two, but Retains the same size and form factor as regular RCA ports.
