Dieses Display ermöglicht nicht nur die Anzeige von mehr Informationen auf einmal, sondern auch eine größere Schriftart - so können Sie den Gerätestatus leichter erkennen und verschiedene Einstellungen ändern. Zwei Ausgänge Neben dem standardmäßigen 3,5-mm-Kopfhörerausgang verfügt der BTR15 auch über den weit verbreiteten symmetrischen 4,4-mm-Kopfhörerausgang, der im Vergleich zum symmetrischen 2,5-mm-Ausgang eine höhere Kontaktsicherheit und Haltbarkeit bietet. Dank der beiden Ausgänge können Sie den BTR15 mit mehreren Kopfhörern verwenden, um ein noch besseres Hörerlebnis zu erzielen. Unabhängige Stromversorgung für Verstärker - Explosive Kraft - Elektrizität ist die Mutter des Klangs Vor diesem Hintergrund haben die FiiO-Ingenieure eine unabhängige Stromversorgung für den Kopfhörerverstärker des ES9219MQ entwickelt - das bedeutet, dass der Kopfhörerverstärker keine gemeinsame Stromversorgung mit dem DAC-Teil hat. Dies führt zu einer reineren und robusteren Stromversorgung für den Kopfhörerverstärker. Paralleler Ausgang, mehr Leistung Sie müssen nicht den symmetrischen 4,4-mm-Ausgang verwenden, um die Vorteile der höheren Ausgangsleistung zu nutzen. Um die Leistung des BTR15 in jeder Hinsicht zu verbessern, hat FiiO die Kopfhörerausgänge parallel geschaltet, um auch die Ausgangsleistung des 3,5-mm-Single-Ended-Ausgangs deutlich zu erhöhen und so niederohmige Kopfhörer besser anzusteuern, damit Sie deren Potenzial besser ausschöpfen können. Umfassender Batterieschutz Um die Sorge um den Zustand der Batterie zu nehmen, haben die FiiO-Ingenieure eine Reihe von Software- und Hardware-Maßnahmen implementiert, um die Batterie des BTR15 umfassend zu schützen. Batterie-Isolierung: Wenn der BTR15 an einen Computer angeschlossen ist und über einen längeren Zeitraum im USB-DAC-Modus verwendet wird, kann der Akku nicht mehr aufgeladen werden, sondern wird vollständig vom Computer mit Strom versorgt, wodurch eine Schädigung des Akkus vermieden wird; Langlebige, hochtemperaturbeständige Batterie: widerstandsfähiger gegen hohe Temperaturen für eine längere Lebensdauer; Eingebauter Temperatursensor: dynamische Erkennung von Ladung und Entladung und automatische Anpassung des Ladestroms in Abhängigkeit von der Temperatur* verhindert effektiv thermische Schäden am Akku. *Erkannte hohe Temperaturen führen zu einer Anpassung des Ladestroms.

FiiO BTR7 - Portable Bluetooth amplifier at its bestThe FiiO BTR7 portable Bluetooth amplifier in summary:Listening to music on the go in the best quality is actually quite simple. With the right headphones and a portable Bluetooth amplifier like the FiiO BTR7. Not only does it offer Bluetooth 5.1 and all the latest high-quality codecs, it also has an integrated USB DAC and a balanced 4.4 millimetre jack connection. Curious now? Then just read on.The highlights of the FiiO BTR7 at a glance:- Here's where you connect - Via Bluetooth 5.1 and via USB DAC- The best of both worlds - 3.5 mm single-ended + 4.4 mm balanced jack output- Fully Balanced Construction - Powerful and Low Noise Thanks to THX-AAA- Strong together - Dual DAC ESS9219 with large format support- Always well informed - Integrated colour IPS displayReady for a firm connection - Wireless via Bluetooth 5.0 and moreNot all Bluetooth is the same. You will find this out at the latest when you get to grips with the various codecs such as SBC, AAC, aptX, LL, aptX HD, aptX Adaptive and LDAC. Each has its own justification and its own field of activity.If the aim is to minimise latency (i.e. the delay in transmission from the transmitter to the receiver), then aptX LL (LL = Low Latency) is a good choice. If, on the other hand, high sound quality is required, LDAC is ready and waiting to please. And for everything else, there is a whole range of other codecs integrated into the FiiO BTR7.And with Bluetooth 5.1, you don't have to worry about range (more than 10 metres is usually possible) or interference from smartphones, for example. Everything simply works as it should! Don't believe it? Then try it out and see for yourself.Small Bluetooth amplifier big time - can also be used as a USB DACAs beautiful as Bluetooth is, sometimes it needs to be a bit more. For example, music in the highest quality as DSD256, MQA or simply PCM in 384/32 kHz/bit. To ensure that no detail is lost with such Hi-Res formats, you can also connect your smartphone, laptop or any other compatible device to the amplifier via a USB-C or Lightning cable (the FiiO BTR7 is available in two versions) and enjoy music in the highest quality.Sometimes a cable just might be nice after all.It's nice to have a choice - balanced and single-ended headphone output.The world is complicated enough as it is, so sometimes it's nice not to have to worry about everything. Like the headphone jack, for example, when you want to listen to music. With the FiiO BTR7, you decide how you want to be connected. Classically via 3.5 millimetre jack or symmetrically via 4.4 millimetre jack.While the 3.5 millimetre jack connection is the flexible choice for almost any headphone, the balanced connection offers significantly more potential. Both in terms of sound and performance. In balanced mode, both amplifiers in the FiiO BTR7 work in parallel at peak performance and, moreover, any interference during transmission to the headphones cancels each other out thanks to balanced operation.Now it's up to you.Uncompromising amplification and balanced design - with THX AAA™ technology.THX AAA™ stands for "Achromatic Audio Amplifier", i.e. amplifier technology that is virtually free of sound coloration of any kind. And the almost unavoidable background noise and distortion in the sound image are also reduced to an absolute minimum.To make this work, the FiiO BTR7 is strictly symmetrical internally, preventing the two channels from "getting in each other's way". All that remains is a punchy and powerful sound. Or expressed in numbers, this means that in single-ended mode (3.5 mm jack) 150 milliwatts of power are available, in balanced mode 4.4 mm jack) correspondingly double the power (300 milliwatts).We think that's something to see (and hear!)!Double is better - Dual DAC ESS9219 on boardAs befits a balanced design, there is of course not just one D/A converter at work in the FiiO BTR7, but two. Each for one channel. And they don't just come from anyone, but from the American digital specialists ESS Technology.This means that not only are formats such as PCM in 32/384 bit/kHz, DSD256 and MQA on board, but also in the best quality with a high signal-to-noise ratio and fine resolution. Absolutely worth hearing!Not only listening to music, but also seeing it - On the built-in colour displayIt's nice to know what's playing. Or at least what codec is being used. From now on, the 1.3"/3.3 centimetre IPS colour display with its resolution of 240 x 240 pixels informs you about this. And if you want to know and set even more, you can do so very simply: via the FiiO Control App available for iOS and Android.Ready when you are - even over long distances.With its 880 mAh battery capacity, the FiiO BTR7 won't run out of steam in a hurry. Depending on the codec, volume setting and headphones, you can enjoy up to nine hours of music on the go. Battery empty? After 1.5 hours at the socket, the fun can start all over again!And with its 68 grams of weight, it is also much lighter than a standard bar of chocolate. And exercising is healthier than eating chocolate anyway.So, which version should it be? The FiiO BTR7 with USB-C or the variant with Lightning connector? No matter which you choose, we guarantee lots of fun with the device!

FiiO CP13 Analogue and simply good - We are reviving the old treasures from your childhood and youth Hotly anticipated. Anyone who grew up in the 80s and 90s will remember the feeling when the presenter on the radio messed up the beginning or end of a track when recording a mixtape. That was annoying. You were all the more proud when you were able to capture the latest hits of the 80s on tape without interruption. Bring these treasures and your old radio play collections back to life with the FiiO CP13. But why did FiiO of all companies come up with the idea of bringing this topic back to life? The answer to this question is quite simple. Since its inception fifteen years ago, FiiO has been dedicated to the amplification and high quality reproduction of analogue audio signals. The common intersection of this classic and modern digital theme is therefore tailor-made for FiiO. We can therefore look forward to an old idea in a new guise. One of the best features is certainly the significantly increased output power compared to the past. This makes the FiiO CP13 capable of driving even the most demanding hi-fi headphones. As the FiiO CP13 is essentially about classic and analogue playback, FiiO has decided not to implement Bluetooth. Digitising a good analogue audio signal and transmitting it via Bluetooth would not do justice to the zeitgeist of the cassette era. Item description Ultra-low jitter Oversized pure copper flywheel for smooth playback Special balanced amplifier head 100% pure analogue sound Classic audiophile operational amplifier JRC5532 High-voltage motor power supply for high synchronisation Two-colour aluminium alloy housing Long battery life of up to 13 hours The classic way to listen In the 1980s and 1990s, cassettes were very popular, and portable cassette players were popular across all generations. Today, however, the supply chain for cassette players is almost non-existent, which made the initial phase of the FiiO CP13 project extremely difficult and almost led FiiO to abandon the project. Fortunately, after investing a lot of time and effort and working closely with the supply chain, FiiO was able to continue working on the FiiO CP13. FiiO may be nostalgic, but it always takes the safe and good-sounding route when it comes to technology. Many small but sonically outstanding details find their way into the new FiiO CP13 to revive the analogue sound. Achieving extremely low jitter through custom-parts made from high quality materials -Tailor-made like clockwork After much trial and error, FiiO has carefully selected between the scarce materials in the supply chain, and finally developed a technology that represents what is currently feasible in this field. The recording and auto-reverse functions were deliberately omitted. The main focus during development was on maximising sound quality. Oversized flywheel made of pure copper The FiiO CP13 features an oversized flywheel made of pure copper with a diameter of 30.4 mm and a thickness of 4 mm. The size of the flywheel helps to ensure that the reel moves as smoothly as possible during playback, thus minimising jitter. This results in synchronisation at the highest level. This results in a more authentic and better sound of the cassette being played, just as we remember it. Power supply of the high-voltage motor The motor of the FiiO CP13 is supplied with a high voltage of 4.2 V, i.e. more than the 1.8 V or 3 V that is usual in today's cassette players. This power supply works in conjunction with a motor speed stabilisation circuit that increases the resistance of the motor as required to ensure stable movement speeds - reducing unwanted pitch changes and allowing the FiiO CP13 to handle more cartridge types. Superior choice - customised cartridge head Regardless of cost, Fiio has negotiated with its supplier that only cartridges of sufficiently high quality are selected. Only 40% of the cartridges produced by the manufacturer meet FiiO's specifications after a total inspection of all units. In addition, the manufacture of the CP13 is strictly controlled to ensure minimal differences in output between the left and right channels, which are far less than in current cassette players. The magnetic head also utilises a thickened head cover that better shields the head from external interference. This also significantly reduces wear and tear on the magnetic head during playback, making it last longer. In contrast to single-ended signal acquisition, which is common in current cassette players, the CP13 uses a differential circuit for symmetrical acquisition of the signals from the head. This results in more stable signal transmission, a higher signal-to-noise ratio and less distortion during playback. Fully analogue circuitry - 100% pure analogue sound For truly analogue playback, analogue devices are used throughout the FiiO CP13's audio circuitry - from the magnetic tape head to the signal amplification. The result is a classic, unmistakably analogue sound. Tape drive, LTA8092 primary signal amplifier, analogue volume control, JRC5532 power amplifier, adapted high-voltage motor, LDO- LDO+ circuit to stabilise the motor speed, boost circuit, 3.7 V lithium battery, Charging and overvoltage protection, USB Type-C The comeback of a classic - audiophile op-amp JRC5532 The FiiO CP13 uses the renowned JRC5532, which some call the classic "king of operational amplifiers". This op-amp is used in a fully analogue audio circuit that delivers a familiar, pleasing sound. Fusion of squares and curves - Two-tone all-aluminium alloy chassis The FiiO CP13 features a carefully crafted two-tone all-aluminium chassis. The "0" screw concept, which perfectly complements the square yet round design, makes the CP13 an example of beauty in harmony with ergonomics. The buttons of the CP13 are hard oxidised in a high-quality process. This makes them more resistant to wear and corrosion. Behind the aluminium alloy volume control is a large analogue volume potentiometer which, compared to the flat potentiometers commonly used in cassette players, is not only more reliable and provides a more stable sound, but also simply feels better. Long playing time - up to 13 hours The FiiO CP13 uses a 1800mAh battery. In fact, the CP13's battery allows for 13 hours of playtime and 268 days of standby time. Dual-mode power supply - Continuous good sound The CP13 is powered by a lithium battery that can be charged via the USB Type-C port when connected to a 5V USB power adapter. FiiO's extensive experience in developing safe charging circuits with protection mechanisms ensures that you can use the CP13 without worry while charging. Small yet big Although the size of the cassette player's disc drive limits the possibilities, FiiO engineers have taken great care to make the CP13 as compact as possible. By integrating manufacturing and structural design, the CP13 is ultimately only 31.8 mm thick, making it thinner and more compact than most cassette players currently in production. Scope of delivery Manual, USB-C cable, protective film for viewing window Specifications Available colours: Sky blue/silver; Black/white; Transparent Supported cassette types: All types I to IV) Output: 3.5mm jack / 2-track stereo playback Dimensions: Approximately 120*88.3*31.8mm Output Level: Greater than 250mV SNR: ＞55dB Weight: Approximately 310g Battery: 1800mAh Battery Life: ＞13 hours@40mV Standby Time: ＞ 268 days Aluminium body / Aluminium knobs and controls Mechanical Logic-Core Copper flywheel
