TPA6120 current feedback headphone amplifier FX-AUDIO- PH-A2J Hi-Fi (black)

【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. Equipped with current feedback type high-end headphone amplifier IC TPA6120 Equipped with LM4562 operational amplifier IC in front stage circuit Gain switching function, dual input switching function Japanese-made parts are used at key points AC adapter required (sold separately) DC12V/1A DC jack 5.5mm x 2.1mm (center positive) A new high-quality headphone amplifier that supports two analog inputs is now available from the FX-AUDIO brand. Equipped with the current feedback type headphone amplifier IC TPA6120, it has the power and high sound quality to easily drive high impedance headphones! You can enjoy the delicate expressive power and powerful drive feel of the high slew rate of the TPA6120 headphone amplifier IC, which was popular in the DAC-X6J, with analog input. Renewal to 3rd lot from January 28, 2022 sales *Changes in the 3rd lot ◆Change of output filter resistance components The resistance components in the output filter section have been changed from DALE (1% accuracy) to 0.1% high precision resistance components. By using high-precision components, the output error value for the left and right output channels has been lowered, resulting in improved sound quality, especially localization. ◆Change of operational amplifier The operational amplifier in the gain adjustment/buffer circuit section has been changed from "OPA2604" to "LM4562". The ``LM4562,'' which is good at reproducing modern sounds and is characterized by high resolution and clear sound, is actually the same circuit as the ``LME49720,'' which has been discontinued and is now rising in price. In response to user feedback, we changed the character from the glossy "OPA2604" to the high-resolution, clear sound "LM4562." It is also excellently compatible with the headphone amplifier IC "TPA6120". Enjoy high resolution, clear and exhilarating sound.
