Once configured, BTR5 runs the EQ processing without the app, for every audio sources over Bluetooth *EQ is invalid under BTR5s LDAC DAC Lowpass Filter 8 different DAC lowpass Channel Balance & Distortion compensation L / R channel volume calibration Second-harmonic/Third-harmonic compensation Technical support for BTR5 1.How does the BTR5 boot up and enter pairing mode? Press and hold the power button for about 3 seconds to turn it on (the display lights up to show “FiiO”). Press and hold the multi-function button for about 5 seconds to enter the pairing mode (the display shows ‘pairing’) after booting up. Click your phone to enter the Bluetooth settings, you can select the BTR5 for pairing. In addition, the first time you turn on the power or clear the pairing information, the BTR5 will automatically enter the pairing mode. 2.Why cant the BTR5 pair and connect to my phone? 1). Does the BTR5 enter pairing mode (press and hold the multi-function key for 5 seconds to enter pairing mode, which will display pairing)? 2). Is your phone scanning for Bluetooth (some phones need to be manually click refresh scan)? If you still cant find the BTR5 device, try to return to the setting and re-enter the Bluetooth on your phone. 3). Confirm that the mobile phone is not connected to other Bluetooth devices. If there is a connection, please disconnect it first. 4). Due to the difference in phones of various brands, you can try several times when appearing faults. 5). When using NFC, make sure your BTR5 is turned on and no other mobile phones are connected. 3.How to clear the pairing record on BTR5? Hold the Volume+ and Volume- buttons for about 5 seconds when the BTR5 is powered on. 4.Why the NFC is not sensitive sometimes? NFC belongs to the near field communication technology. Both NFC sensing areas of the mobile phone and BTR5 must be close to each other to be sensed. The NFC power of each mobile phone is also different (especially the NFC sensing sensitivity of the metal case mobile phone is low). With the case on, some phones NFC would become less sensitive. It is recommended to remove the phone case and try again. 5.Does the BTR5 support idle time power off? Yes, it supports idle time power off for saving power. When its connected to other devices, it will enter standby mode if no music playing. When its not connected, it will power off automatically after 2 minutes. Its battery life is about 300 hours in idle time. 6.Is there a delay for BTR5? If there is, how long? Actually, any Bluetooth device will have a delay under the current technology. And there is no obvious influence on listening to music. The time of delay is different with the different Bluetooth codecs. The BTR5 can support aptX LL( low-latency encoding), with a delay of less than 40ms. For other Bluetooth codecs, the delay is more than 100ms. 2. Whether it will be upgrated depends on whether the existing encoding format is updated. 7.How to set up the BTR5 in FiiO Music app? Here is steps to set up BTR5 in FiiO Music app: 1. FiiO Music app should be also updated to the latest version firstly; 2. When FiiO Music app is already the latest version, enter the setting of the app, click on Bluetooth device control to find BTR5, click connect. After the connection is successful, it will enter the Bluetooth control interface. 8.Does the BTR5 support a headsets remote control and the microphone? The BTR5 supports the CTIA standard for line control as well as line microphone. But the headsets with OMTP protocol only support normal listening. 9.EQ is invalid under BTR5s LDAC. Is it a hardware defect or a software problem? Not a hardware defect. Since the audio processing process of LDAC is more special than other Bluetooth formats, we are still doing related debugging, and strive to achieve the same effect as other Bluetooth formats, but it will take a certain amount of time. 10.What if the BTR5 appears to be frozen? How to reset BTR5? When the BTR5 is frozen, please try to hold the Power button for at least 10 seconds to reset the BTR5.

Guten Tag, Ich verkaufe hiermit einen Fiio BTR5 2021 Bluetooth Kopfhörerverstärker, da ich ihn nicht mehr benötige. Der BTR5 ist in sehr gutem Zustand und hat nur vorne an der unteren Kante einen kleinen sichtbaren Kratzer. Er funktioniert einwandfrei sowohl über den 3.5mm als auch über den 2.5mm-balanced Anschluss. Für weitere technische Informationen schauen Sie auf der offiziellen Fiio Seite. Im Lieferumfang enthalten sind der BTR5, ein transparenter Clip, ein USB-A auf USB-C Kabel und zusätzlich lege ich noch eine offizielle Fiio Lederhülle dazu. Das Gesamtpaket wird zudem in der OVP verschickt. Für Fragen stehe ich Ihnen zur Verfügung. Hinweis: Da es sich um einen Privatverkauf handelt, schließe ich Garantie, Gewährleistung und Rücknahme aus.

Cleaning out of much of my Hifi equipment, score a great deal on a great portable DAC. Includes DAC, a USB-C cable, and clip. The BTR5 was FiiOs flagship portable Bluetooth DAC/Amp. With an updated ESS Hyperstream III DAC chip, better performance, and MQA support, the 2021 version takes the popular pocketable to new heights.Portable is an understatementThe BTR5 2021 is small.

The Double DACDon’t let its humble dimensions fool you: the BTR5 2021 packs a punch. Its two ESS SABRE ES9219C digital-to-analog converters (DACs) boast -114dB THD+N and 130dB SNR.Its all in the balanceThe BTR5 2021 has both balanced and single-ended outputs. In its balanced audio architecture, each channel is driven separately with its own DAC and amplifier, ensuring unmatched finesse.Asynchronous decodingWith an XMOS XUF208 control chip, the BTR5 2021 is capable of asynchronous audio decoding via USB. It can decode up to 384kHz and Native DSD.State-of-the art Bluetooth 5.0 Gone are the days of lousy bluetooth downsampling. Boasting Qualcomm’s flagship Bluetooth 5.0 chip, the CSR 8675, the BTR5 2021 supports 24-bit transmission of lossless codecs: AAC, SBC, aptX, aptX LL, aptX HD, and LDAC.MQA modeA new addition to the BTR5 2021 is support for MQA, allowing for high-res, master-level sound quality in reasonably-sized files that are suited for your mobile device.Independent dual crystal oscillators If you’re going to decode massive 24-bit lossless codecs, you better have a plan for reproducing them accurately. Fortunately, the BTR5 2021 includes dual crystal oscillators. These 45.1584/49.152 crystals eliminate jitter for a super stable sonic experience. SuperchargedWith a built-in 550mAh battery, the BTR5 2021 only takes an hour and a half to fully charge but lasts up to nine hours!Crystal clear callsTake a phone call with the BTR5 2021s built-in omnidirectional microphone or use an external 3.5mm headset. Either mic benefits from cVc 8.0 noise cancellation technology, which intelligently adjusts the microphone gain and effectively suppresses background noise for crystal clear calls.Auto USB modeWhen a USB connection is detected, the BTR5 2021 will automatically prompt you to turn on USB Audio Adapter mode, which turns off charging to the BTR5 2021 and allows you to use it as an audio dongle for your phone or other devices.Product highlightsHigh performance ESS ES9219C x2 DACsMQA supportCSR8675 Bluetooth chip supports 24-bit audioDual crystal oscillatorsXMOS XUF208 USB chip supports up to 384kHz, DSD256USB audio adapter modeOLED display3.5mm + 2.5mm dual outputsFiiO music appIn-vehicle mode automatically turns on and off with your carSpecsAudio DAC: ESS HyperStream III ES9219C x2Bluetooth profile: HFP, HSP, A2DP, and AVRCPBluetooth version: 5.0Supported audio formats / codecs: SBC, AAC, aptX, aptX LL, aptX HD, and LDACDriver free mode: supportedIn-vehicle mode: supportedNFC: supportedMic function: Supports Bluetooth calls, built-in omnidirectional microphone, external microphone of CTIA cableUSB port: Type-CRecommended headphone impedanceSingle-ended: 16-100?Balanced: 16-150?Volume control: Side buttonsStatus indication: Display indicates the Bluetooth code, charging, battery, volume, sampling rate, menuBluetooth chip: CSR8675USB DAC chip: XMOS XUF208USB sampling rate: 384 kHz / 32-Bit and DSD 64/128/256THD+N3.5mm Output: ?0.003%2.5mm Balanced Output: ?0.002%SNRPO: ?118 dB (32 Ohms A-Weighted)BAL: ?122 dB (32 Ohms A-Weighted)Transmission Distance: 32.8 (10m) (Open Areas)Channel Balance: ?0.1dBGain: Supported (High/Low)Display: 0.5 (12.7mm), 64 x 32 pixel OLEDHeadphone Output1 x 1/8 / 3.5 mm (PO)1 x 2.5 mm (Balanced)Output PowerPO: About 80 mW (32 Ohms Loaded)PO: About 90 mW (16 Ohms Loaded)BAL: About 240 mW (32 Ohms Loaded)BAL: About 240 mW (16 Ohms Loaded)Output ImpedancePO: ?1.0 Ohms (32 Ohms Loaded)BAL: ?2.0 Ohms (32 Ohms Loaded)AmplitudePO: 1.6 V (32 Ohms / THD+N PO: 1.8 V (No Loaded)BAL: 2.8 V (32 Ohms / THD+N BAL: 3.6 V (No Loaded)Frequency Response20Hz to 20kHz (aptX Connection)20Hz to 40kHz (LDAC Connection)Drive Ability16 to 100?
