FiiO BTR15 / BTR 15 Portable Bluetooth DAC and Headphone Amplifier

Change modes with just one button Due to the BTR15 #39;s ability to work as a Bluetooth receiver and as a USB DAC, we have implemented a PC/BT/PHONE mode button on it. With just a click of a button, you can quickly switch between the three different modes. 0.96-inch OLED display Like its bigger brother the BTR7, the BTR15 also features a large display - a brilliant 0.96-inch OLED display. This display not only allows displaying more information at once, it also allows for larger display fonts. Dual-core upgrade - Two modes of high-res audio The upgrades start from the heart of the BTR15, specifically the cores that power it. The BTR15 employs the high-performance combination of the Qualcomm QCC5125 Bluetooth chip XMOS 16-core XU316 that supports stable high-res audio playback in any mode. Independent power supply for amp - Explosive power Feiao engineers have carefully designed an independent power supply system for DAC ES9219MQ built-in. In addition, the uniquely designed external power supply has the characteristics of low noise and high current, which increases the balanced output power of BTR15 by 40% to 340mW.
