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

------------------------------------------------------------------------------------------------------------------ 【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. ------------------------------------------------------------------------------------------------------------------

Equipped with current-feedback type high-end headphone amplifier IC TPA6120 The preamplifier circuit incorporates an LM4562 operational amplifier IC. Gain switching function, dual input switching function Japanese-made parts in key areas AC adapter required (sold separately) DC12V/1A DC jack 5.5mm x 2.1mm (center positive) FX-AUDIO- brand introduces a new high-quality headphone amplifier with two analog inputs. Equipped with the current-feedback type headphone amplifier IC TPA6120, it delivers power and high sound quality that can easily drive even high-impedance headphones! The DAC-X6J's highly acclaimed TPA6120 headphone amplifier IC offers both delicate expressiveness and powerful drive thanks to its high slew rate, and you can now enjoy these features with analog input. The product will be renewed to its third production batch, available from January 28, 2022. *Changes in the 3rd batch ◆Changes to resistor components in the output filter section The resistors in the output filter section were changed from DALE (1% precision) to 0.1% precision resistors. The use of high-precision components has reduced the output error between the left and right channels, resulting in improved sound quality, particularly enhanced sound localization. ◆ Operational amplifier change The operational amplifier in the gain adjustment and buffer circuit section has been changed from "OPA2604" to "LM4562". The "LM4562," which excels at reproducing modern sounds and is characterized by its high resolution and clear, transparent sound, actually uses the same circuit as the "LME49720," which has been discontinued and is now highly sought after. Based on user feedback, we've changed the character of the chip from the glossy "OPA2604" to the high-resolution, clear-sounding "LM4562". It also works perfectly with the headphone amplifier IC "TPA6120". Enjoy high-resolution, clear, and exhilarating sound.
