Change
modes with just one button
Due
to the BTR15'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 to match your
current scenario for listening to high quality music.
PC:
contact as a USB DAC, totally powered by the computer.
BT:
Bluetooth DAC and amp, powered 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, be the master of your music
The
BTR15 features a global parametric equalizer (PEQ). Through FIIO's
self-developed PEQ algorithm and user interface, in any mode* you can choose
the exact frequencies to be adjusted along with their gain levels and bandwidth
- allowing you to fine-tune the sound to exactly the way you want it.
PEQ
notes:
*BT
mode PEQ adjustments are implemented through the QCC5125 DSP with support for
LDAC and other Bluetooth formats up to 96kHz/24Bit.
*PC/PHONE
mode PEQ adjustments are implemented through the XMOS XU316 with support up to
PCM 192kHz.
*PC/PHONE
mode PEQ adjustments are implemented through the XMOS chip. Enabling or
disabling the PEQ, USB will restart and disconnect.
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*, allowing you more ways to immerse yourself in the world
of high-quality Hi-Res music.
Sampling
rate notes:
*BT
mode supports LDAC/aptX Adaptive/aptx LL/aptX HD/aptX/AAC/SBC and other
high-resolution Bluetooth formats with sampling rates up to 96kHz;
*PC/PHONE
modes support asynchronous decoding up to 384kHz/32Bit PCM and DSD256.
MQA
Full Decoder for master-quality sound
The
BTR15 supports MQA Full Decoder*, which means the MQA decoding can be achieved
in any music app. This allows for high-resolution, master-level sound quality
in reasonably sized files well-suited for your mobile device.
*Supports
up to 384kHz sampling rate
Dual
curved glass, dual upgrades to look and grip
With
the BTR15, FIIO uses hot-bent curved glass for the first time - embedding it on
both the front and the rear of the device. Not only does this make the device
easier to hold, but it also gives the BTR15 a more attractive and 3D appearance.
Together with the aluminum alloy middle frame, they make the BTR15 a
comfortable device to handle - you won't be able to put it down once you pick
it up.
0.96-inch
OLED display, see all the info with just a glance
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 - making it easier
for you to see the device status and change various settings. Moreover, it is
the rarely seen device that supports bilingual languages, Chinese and English,
among similar products.
Dual
outputs, covering all angles
In
addition to the standard 3.5mm single ended headphone output, the BTR15 also
comes with the widely- used 4.4mm balanced headphone output - featuring greater
contact reliability and durability compared to the 2.5mm balanced out. The dual
outputs ensure you can use the BTR15 with more headphones, for more remarkable listening
experiences.
Independent
power supply for amp explosive power
Electricity
is the mother of sound. FIIO engineers have carefully designed an independent
power supply system for DAC ES9219MQ built-in earmuffs, So that earmuffs no
longer share the power supply with DAC and the power supply is purer. 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, and can easily meet the needs of portable use.
Parallel
output, more power
You
don't have to use the 4.4mm balanced output interface to enjoy the benefits of increased
output power. In order to improve the performance of the BTR15 in every aspect,
FIIO connected the headphone outputs in parallel to also greatly increase the
output power of the 3.5mm single- ended output to better drive low-impedance
headphones, allowing you to better unlock their potential.
Comprehensive
battery protection from worry to peace of mind
In
order to alleviate concerns about battery health, FIIO engineers have
implemented a number of software and hardware measures to comprehensive protect
the BTR15’s battery.
Battery
isolation: when connected to a computer and used in USB DAC mode for long
periods of time, the BTR15 can stop battery from being charged and can be totally
powered by 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 and charging current
automatic adjustment based on temperature* effectively prevents thermal damage
to the battery.
*Detected
high temperatures will result in charging current being adjusted. Depending on
the device’s current state, charging may be reduced in speed or turned off.
Specially
crafted inside and out, it is a joy to use
Aluminum
alloy antenna, wide directionality, and stable signal.
