Digital Integrated Amplifier with YDA138 Digital Amplifier USB DAC FX-AUDIO- YD-202J Dual-mono IC, Input, Built-in (Black)

Features tone control, loudness control, gain boost, and mute function. Three input options (RCA/3.5mm/USB), electronic volume control, USB-DAC, and built-in headphone amplifier. Dual-mono digital amplifier with two YAMAHA YDA138 digital amplifier ICs. Dedicated remote control included as standard. AC adapter required (sold separately) DC12V/2A DC jack 5.5mm x 2.1mm (center positive) This is a digital amplifier with a dual-mono amplifier configuration, featuring two YAMAHA YDA138 digital amplifier ICs. USB-DAC function, 3-input switching, electronic volume control, tone control function, headphone amplifier. This is a multi-functional and fun amplifier equipped with features such as loudness control and gain boost. Initially, this model was designed entirely in-house as a successor to the Lepai LP-2020A+, which we previously sold, inheriting its functions and sound characteristics. We developed it as such, but after gathering feedback received from the sale of the prototype lot, we decided on a dual-mono configuration. We've shifted to a Pure Line concept that leverages its unique characteristics, further improving both sound quality and ease of use! This will be the 6th production batch, available from May 7, 2021. [Changes from Lot 5 to Lot 6] Changed the capacitor in the output stage LPF circuit.
