Bluetooth
Bluetooth is a wireless technology for data transfer between enabled devices over short distances. Intended to be a universal means of communication, it is supported by a vast number of consumer electronics. A common use is for the transfer of audio between mobile devices and headphones.
Bluetooth has been developed through many years and audio quality has been highly improved throuhgout the years, by use of Apt-X protocol for loss less streaming.
Bluetooth is of swedish origin, and takes its name from the danish king of old, Harald Blåtand (Bluetooth being the anglicised form), who united dissonant danish tribes into a single kingdom. The logo is a merging of the runes for "H" and "B", the king's initials.
High impedance (HZ) amplifiers and speakers for use in larger 70/100 Volt installations playing from the same amplifier channel. 100 Volt systems are often used where many loudspeakers must be installed in parallel, e.g. in hotel corridors, lobbies, restaurant and banquet rooms and outdoor speakers. 100V speakers are available both as built-in or for wall mounting.
Remember that both speaker and amplifier must be approved for 70/100V operation and are not normally used in Hi-Fi contexts.
Impedance type – Low (LZ) | 4/8 Ohm
Amplifiers or speakers with low impedance (4-8 Ohm / LZ), which are used in regular mono and stereo systems. It is primarily used in low-impedance loudspeakers and systems, stereo and surround systems, as well as in simple professional installations, where normally only one to two loudspeakers are included per unit. channel.

Music streaming – MQA
MQA is a high resolution streaming technology that gives you original master recording quality from a music streaming service. It’s the core of TIDAL’s vast TIDAL Masters catalogue. And while far from exhaustive, it does include some pretty incredible works of art.
These are albums you can stream at resolutions up to 24-bit, 192kHz, giving you a mind-boggling resolution that helps create a deeper, more immersive listening experience.
However, none of this is without certain caveats. While TIDAL Masters will offer up 24-bit, 192kHz, just because it’s a Masters track doesn’t mean it will hit those incredible heights. In fact, most don’t. The majority of masters titles are going to sit somewhere between 48 and 96kHz, which is admittedly far from the shiny 24/192 that’s continually advertised.
While, yes, not every Masters track is a hefty 24-bit/192kHz in resolution, what you do get is well beyond CD quality.

Roon ready means that the manufacturer has implemented roon labs RAAT network interface protocol directly into the device (network amplifier or streaming player) and has become a certified partner of roon. Thereby, the streaming player / amplifier works with the highest streaming quality from roon via RAAT, which was available at the time of development, and possibly. later via updates.
Roon tested means that devices have a built-in USB-DAC, ChromeCast or Apple Airplay, all of which are compatible streaming options and thus end-points for the roon universe. To get "roon tested", it also requires that the device has been reviewed by the roon labs QA team and thereby registered correctly in the roon software, for optimal streaming utilization.
Devices that have only been "roon tested" cannot take advantage of the full Roon functionality and sound quality achieved with roon's RAAT protocol. To stream with RAAT, it requires that the device is "roon ready" certified. The streaming quality of the sound for "roon tested" devices therefore depends entirely on the type of streaming used and its limitations.

Internet radio has some similarities with DAB: Digital radio with high stability, and no noise issues. Where DAB is transmitted through antennae, internet radio needs an internet connection either through ethernet or WLAN. Internet radio makes it possible to access radio channels from around the world. The feature is most commonly found in tabletop radios, as well as stereo and surround receivers.
Internet radio recieption are often through apps as Vtuner, Last.fm or direct in the streaming software by e.g. Sonos, Yamaha MusicCast eller Bose SoundTouch.

With AirPlay, you can stream sound in high and delicious quality, wirelessly over the network to the devices that support this. Almost all new amplifiers and receivers on the market have support for both Airplay 2 and ChromeCast, which makes it easier than ever to get great sound in the home - without all the hassle.
An amplifier with built-in Airplay 2 (also backwards compatible with Airplay) will in many cases be able to switch on by itself when it detects that you are streaming to it. You then have control to regulate the volume, and of course also switch between the songs or content you may be streaming. Since Airplay 2 makes use of the network, this means that the quality that can be streamed is significantly higher than, for example, Bluetooth, which cannot move anywhere near the same amount of data. If you have an iPhone or iPad and want a simple and delicious streaming solution, take a look at the amplifiers and receivers we offer.
