Product description

• 2 Colors to Present Current Level Temperature Overheat Protection 3-Dimensional Cooler Structure 100 mA mode is a high current Class A operation mode, similar to the GT mode in a racing car. There will be a slow temperature rise. (If the headphone impedance is low, it can lead to a faster temperature rise.) When the device temperature reaches 69 C, due to overheat protection, the S17 Pro will auto switch to 50 mA Class A current mode which still maintains very good sound quality
• Class-A, 2 Levels of Current Gain 50 mA 100 mA per transistor; each channel has 2 pairs of transistors in parallel, so the quiescent current of each channel is as high as 100 mA 200 mA. The sound of a class-A amp is mellow, warm and smooth; 2 gain levels the low gain takes advantage of the class-A amp s feature that the transistors are always working in the linear area to drive the lEMs well and properly, while the high gain is as high as 7.5 W and thus can drive headphones well with big power
• R2R Electronic Volume Chip Rigorous HiFi Component Selection The S17 Pro uses the R2R electronic volume chip from JRC and the dedicated op-amps to build the 4-way balanced R2R volume control. High control precision, great channel balance, wide soundstage, accurate positioning. The components used for the S17 Pro are high-quality ones that are carefully selected, such as the high-quality HiFi electrolytic capacitors, the ceramic capacitors, the organic thin-film capacitors, the communicatio
• Powerful and Rich-Sounding Aesthetic Tuning The S17 Pro uses the 50 W low-ripple toroidal transformer and dual-power design. Digital control and analog are independent from each other, so the analog part can be free from interference. What s more, it has the 19200 F capacitor array. They together make the S17 Pro so powerful and rich-sounding. The tuning is based on real instrument sounds and music pieces referencing, leading to the signature that is natural and full of musicality
• Please Note - The product must be used at 110V voltage. Excessive voltage will damage the product
