FiiO BTR15 Ενισχυτής Ακουστικών με DAC και Bluetooth
Experience outstanding audio quality on the go with the blue FiiO BTR15, a portable Bluetooth DAC and headphone amplifier that features dual integrated DACs that deliver a refined, detailed, and articulate listening experience, even when listening to music over Bluetooth. At the heart of the BTR15 is the dual ES9219MQ DAC chips, which handle sample rates and resolutions up to 384 kHz / 32-bit. This DAC is housed alongside the Qualcomm QCC5125 Bluetooth chip to provide support for Bluetooth 5.1, as well as Bluetooth aptX and SBC.
The enclosure is crafted from hot-bent curved glass on the front and back with an aluminum alloy middle frame, which provides ample protection, as well as a space-age 3D aesthetic that not only looks great, but is easy to handle. The built-in rechargeable battery lasts for up to eight hours, ensuring you can listen to music wirelessly for a long time. If your iOS or Android device doesn’t have a 3.5mm headphone jack, this can serve as a high-quality method to stream great-sounding music to your device.
Change Modes with Just One Button
Due to the BTR15’s ability to work as a Bluetooth receiver and as a USB DAC, FiiO have implemented a PC/BT/Phone mode button. With just a click of a button you can switch between three different modes to match your current scenario for listening to high-quality music.
- PC: Connect as a USB DAC totally powered by the computer.
- BT: Bluetooth DAC and amp powered by the BTR15’s internal battery; when connected via USB, it can be charged.
- Phone: Connect to a phone as a USB DAC dongle, powered by the BTR15’s internal battery.
Global Parametric EQ
Battery Isolation
- When connected to a computer and used in USB DAC mode for long periods of time, the BTR15 can stop the battery from being charged and can be totally powered by the computer, avoiding battery degradation.
Durable High-Temperature Resistant Battery
- More resistant against high temperatures for longer durability
Built-In Temperature Sensor
- Dynamic charge and discharge detection
- Automatic current adjustment based on temperature effectively prevents thermal damage to the battery
