Items in the photos are included! Operation has been confirmed! There are small scratches, but it is in a clean condition without any noticeable scratches or stains! Please check the photos before purchasing! ● Product Features ◆ High-quality full digital amplifier supporting 192kHz from input to amplifier output The entire process from digital input (optical or coaxial) to the amplifier output stage is fully digitized, and the analog signal is first extracted at the speaker output terminals. Furthermore, it supports sampling frequencies up to 192kHz in all stages, allowing for realistic playback of high-quality 192kHz/24bit sources. Also, it converts analog audio to 192kHz/24bit and performs 32bit processing with a 32bit DSP, resulting in a high-quality design, so you can fully enjoy the high sound quality of DVD Audio. ◆ High-precision full digital processing of digital signals Digital signals are processed digitally at a high speed of 98MHz, realizing wide-band playback without frequency dependence. In addition, VGDA (Variable Gain Digital Amplifier) technology improves the S/N ratio in the commonly used volume range, enabling clear playback with less noise and closer to the original sound. ◆ High efficiency because it is a digital amplifier Digital amplifiers significantly reduce unnecessary heat loss (energy efficiency of 90% or more) and efficiently convert input signals into acoustic energy. As a result, we have realized an amplifier with low heat generation and power consumption that is also environmentally friendly. ◆ Supports wide-band power band of 88kHz playback that fully supports DVD audio, a wide-band power band of 88kHz that is difficult to achieve even with high-end analog amplifiers. Furthermore, it secures an industry-leading S/N ratio of 103dB. Please note that the product images may differ slightly in color and texture from the actual product.
