Variations

It is a headphone amplifier.

USB DACとDDC機能を搭載したコンパクトプリ＆ヘッドホンアンプの「AUDINST/HUD-mx2」は、現行モデルの「HUD-mx1」の音質をさらにグレードアップし、新たにオプティカル入力を搭載。非常にクリアで高い解像度と空間再現力を実現。USBバスパワーのみで光デジタル入力（最大24bit/192kHz）とUSB入力（最大24bit/96kHz）に対応し、付属のアダプター接続時にはOPAMPの駆動力を最大限に発揮することが可能なため、より高い出力ゲインと高音質での鑑賞が可能です。

■ Headphone Amplifier

■ The HUD-mx2 is a compact preamplifier and headphone amplifier equipped with USB DAC and DDC functionality, developed to deliver the highest sound quality and convenience.
■ It further upgrades the sound quality of the current model, the HUD-mx1, and now features an optical input. It delivers exceptionally clear sound, high resolution, and spatial reproduction, and was developed over a long period of time using numerous high-quality components and outstanding PCB design technology.
■ It supports optical digital input (up to 24-bit/192kHz) and USB input (up to 24-bit/96kHz) using only USB bus power. When connected with the included adapter, the OPAMP's driving power is maximized, allowing for higher output gain and superior sound quality.
■ It can also be connected to devices that support USB audio, such as an iPad (with Camera Connection Kit) and smartphones that support USB Audio (with USB OTG cable). When used with USB input from a PC, it supports automatic power on/off and sleep mode, maximizing power efficiency for increased convenience and eco-friendliness.

■ Top-of-the-line DAC and powerful dual headphone amplifiers
- Constructed with the finest components and circuitry to reproduce sound as close to the original as possible. Compatible with both stereo phone and stereo mini jack standards, eliminating the need for additional conversion adapters. The dual headphone output provides sufficient driving power even when using 600Ω headphones, delivering clean, high-resolution sound.
■ High-end performance
- Equipped with a 24-bit/96kHz USB audio controller TENOR chipset. Wolfson's high-performance D/A converter and USB power alone provide sufficient driving power, eliminating the need for separate driver installation. This provides the ultimate USB audio solution.
■ Compatible with iPad (with Camera Connection kit) and smartphones that support USB Audio (with OTG cable)

■ High-purity TCXO used for the USB controller clock generator

■ High-performance ALPS potentiometer and premium aluminum knob used for the front panel volume control

■ High-quality WIMA film capacitors used for the low-pass filter
■ Eight dedicated regulators and high-performance low-ESR and tantalum capacitors used to ensure stable, high-quality power supply

■ High-performance super low-ESR and high ripple current solid capacitors used for the DAC power supply

■ High-quality Vishay-Dale metal film resistors used in high-end audio equipment

■ DDC function for outputting USB digital audio signals to S/PDIF (Optical)

■ Supports 88.2kHz sampling frequency, not used by many USB Audio DACs

■ Anti-POP circuitry eliminates unwanted noise generated when powering on/off
