Dual ES9219C DAC
Each channel of the BTR7 hosts an ESS ES9219C digital-to-analog conversion chip, each accompanied by a low-pass filter and amplifier. The whole is optimized within an audio architecture allowing a detailed and dynamic reproduction. In addition, these chips are capable of playing high-resolution streams and decoding MQA files.
Double THX AAA-28 amplifiers
The BTR7 is the first portable Bluetooth amplifier to use two THX AAA-28 amplifier chips in a fully balanced design, allowing for high power output.
Bluetooth 5.1
With the integration of a Qualcomm QCC5124 Bluetooth 5.1 receiver chip, you can enjoy your music without the hassle of cables. This chip is also compatible with the high-resolution transmission codecs aptX HD, aptX Adaptive and LDAC.
XMOS USB Interface
An XMOS XUF208 USB interface is associated with the BTR7's DACs, in order to receive and decode the audio stream from the device's USB-C input. This chip allows the support of high quality files, up to PCM 32bit 384kHz and DSD256, but also the decoding of MQA 8x files.
Comfortable autonomy
With its 880mAh battery, the BTR7 offers comfortable battery life for all-day use. In addition, it supports fast charging and even wireless charging.
IPS Screen
The front panel of the BTR7 features a beautiful 1.3" color IPS display. This one allows the display of the playback information, such as the level of volume, battery, gain or the audio format, for a more intuitive use.
Balanced & Single-ended
The FiiO BTR7 offers a dual output, which fits perfectly to the headphones available on the market. The first one is single-ended, in 3.5mm jack format and the second one balanced, in 4.4mm jack format. This last one allows to take advantage of a more important output power.
Control app
The BTR7 is compatible with the FiiO Control mobile application. It detects your device and lets you control it, without even taking it out of your pocket. It even offers access to additional features, such as an equalizer. It's also the best way to update your device's firmware in a very simple way.
