---------------------------------------------------------------------- ------------------------------------------------------------------------------------------------------------------ 【Cautions for using electrical products】 When using electrical appliances, please note that the voltage is different from that of Japan, which may cause malfunctions. Since the plug type is Japan type(A or B type), please check the voltage and use a transformer. Please note that a transformer is different from a conversion adapter. We are not responsible for malfunctions caused by use without a transformer. ------------------------------------------------------------------------------------------------------------------ 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 expressiveness 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 parts 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 of 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 with good visibility, 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.
