GAMEedition No box. Used a few times, but selling due to a change in environment. DAC connection, optical digital connection. According to Amazon reviews, it can also be connected to PS5 and Switch 2. The following is quoted from the product description. 【USB bus-powered DDC】 A DDC (Digital to Digital Converter) that supports USB AUDIO CLASS 2.0 and high-resolution audio up to 24bit/192kHz. After the sale of "FX-D03J", many users requested: "I want it to support 24bit/192kHz" "It would be even more convenient if it supported it." This is an upgraded model born in response to these requests! ※ This is not a model change, and "FX-D03J" will continue to be sold in parallel. ■ Optimizes each of the two output systems with a logic amplifier! To maintain good output characteristics by reducing the output load of the audio controller IC, amplification is performed using a logic IC, the same as with mid- to high-priced DDCs, and the signal level is optimized for each of the optical/coaxial digital output terminals to achieve improved transmission quality. Pulse Electronics' reliable pulse transformer is used for the coaxial side! Electrical isolation ensures stability. In addition, NXP's 74HC04D, which has good rise and fall characteristics, is used for the logic IC that generates signals suitable for digital output terminals. ■ Gold-plated coaxial digital RCA terminals and shuttered optical digital terminals are used. High-quality parts that support 24bit/192kHz are used for the optical output terminal. Considering the situations in which it will be used, it has a shutter to prevent the loss of protective caps and shut out dust and dirt. The coaxial digital terminal is a high-quality gold-plated type that resists oxidation and dirt. 【Product Specifications】 Color: Black Digital Input: USB TypeB terminal, USB1.1/2.0 compatible, USBAudioClass1.0/2.0 compatible Digital Output: Coaxial digital audio output (COAXIAL) Optical digital audio input (square type) ※ Can be used simultaneously Supported formats: PCM up to 24bit 192kHz Audio controller IC: SAVITECH BRAVO-HD SA9123 Accessories: Instruction manual Size: Width 40mm x Depth 81mm x Height 25mm (excluding protrusions) Weight: 90g
