Great value wireless sound for video

There are many different ways of capturing sound for video recordings and all of them have their advantages and disadvantages. The t.bone Sync 2 pretty much avoids all the disadvantages: it is cheaper than RF systems offered by other brands, sounds much better than the integrated mics on mobile phones or cameras and wirelessly transmits the sound of two emitters via radio waves to a single receiver, making it extremely flexible in use since it does away with the hassle of tangled cables. In addition, the t.bone Sync 2 is small, light and easy to transport, all the more so since a soft case is provided in which all its equipment and accessories can be stored. The latter consist of a TRS cable for connecting the receiver to a camera or computer, a TRRS cable for connecting to a mobile phone, two lavalier microphones and four dedicated windshields, two for the transmitter’s integrated mics and the remaining two for the lavalier mic. Finally, a split USB A to 3x USB C cable is provided, allowing both transmitters and the receiver to be charged simultaneously using a single USB socket.

Sound is under control

A charging time of 1.5 hours allows the system to run for about 5 hours, which is sufficient for extended filming sessions – during which you can take full advantage of its impressive transmission range of roughly 50m, when the transmitter and receiver are within direct line-of-sight. This makes for great outdoor recordings without any sound loss. And even if obstacles are present between transmitter and receiver, the system will still work just fine up to a distance of 30m. Though the transmitter’s two integrated microphone provide the simplest and most direct option for sound recording, the t.bone Sync 2 package also includes two lavalier microphones which can be inconspicuously placed on a collar and come each with a windshield. The overall system latency is only 12.5ms, well below the duration of a single video frame, even when filming at 60fps – the sound is thus seamlessly integrated into the picture. The receiver is equipped with a dedicated volume output which can be adjusted in four distinct steps as well as a headphone output, useful for direct monitoring.

For demanding filmmakers

The t.bone Sync 2 is perfectly suited to hobbyists and social media filmmakers who might have two subjects at the same time, for example during interviews and dialogs. If your camera equipped with a hot shoe, then just fix the receiver onto it and the audio can then be recorded straight to the camera via the provided mini-jack cable. Of course, this same cable can also be connected to a mobile recorder, mixing console and of course to a computer. Both transmitters and their respective mics can of course also be placed anywhere you want. They generally stay attached to each person being recorded, and, weighing only 35g each, are hardly a burden. Alternatively they can be tucked away on belts thanks to the included clips and then the inconspicuous lavalier microphones can be used, discreetly placed on the lapels of their subjects.

About the t.bone

Since 1994, the t.bone has been part of Musikhaus Thomann’s in-house brands. Devices such as headphones, wireless systems, in-ear equipment as well as various microphones and matching accessories are marketed under the name. ‘the t.bone’ products are built exclusively by well-known manufacturers, who also work for many other well-known brands. This provides a clear advantage: brand quality products at very reasonable prices. And word gets around: one in seven Thomann customers has already bought at least one product from the t.bone.

Amazing hairstyle to reduce wind interference

If you use the transmitter’s mic outdoors, we recommend using the dedicated windshields. These hairy little dudes are included in the package and simply fitted over the transmitters’ mics to reduce wind noise, and still allow speech and other sound sources to be recorded without being affected. The windshield is easy to remove after use. To avoid losing it or forgetting it in your pocket, you should immediately be put it away in its case. Both lavalier microphones are provided with individual foam protectors that fit snugly and should only be removed indoors for cleaning purposes. A switchable Low-Cut Filter is present on each transmitter to reduce low frequency interference, such as the hum of passing vehicles.

Free placement

The transmitter and receiver are provided with clips that fit on a belt - however they are also designed to fit the hot shoe of a camera. You can therefore choose whether to record the sound directly into the camera, or, if you choose to attach the receiver to your belt, the audio can be captured separately onto the recording device of your choice – even to a mobile phone in your pocket. Of course, the receiver can also be placed next to your computer and the audio recorded from there. The receiver can be set to Mono or Stereo. In Mono, the input signal is sent equally to the Left and Right outputs, which is useful when only one transmitter is being used, or when there is a lot of movement in the picture and independent left and right channels would not work. Stereo adds space to the sound during conversations, as long as the subjects keep fixed positions. The output volumes of each transmitter can be individually adjusted to four levels on the receiver. Each click on the volume button increases the output volume by one step and switches back to the lowest level after reaching the highest.

Detailed explanation: Recording Internally vs. Externally

Recording the sound track of your video straight onto your camera or mobile phone is always the simplest solution, since the sound and picture are both recorded in the same video file and don’t need to be later synchronised on a video editing program. However, independently recording your audio tracks on a separate recorder or computer often greatly facilitates post-processing and allows better control of the audio quality overall. For example, many applications let you invert the Left and Right channels if your stereo picture is the wrong way round. You can also bounce down the stereo channels to a single mono track - this way, one can record in stereo and then adjust the volume of each track individually before they are merged into mono.

The microphone quality is a total disaster for the price. One lavelier has a short circuit on the jack itself. There is no limiter, so the sound is distorted, even at low levels. No warranty so i will sell t.bone for half price. The sound from two mics are mixed in two channels, there is no way to separate mics by channels.

Starkes Rauschen, Einfache Bedienung.
Bors 08.12.2021
Wer sich eine Tonqualität auf dem level von Røde erwartet, wird enttäuscht sein. Diese Erwartung ist allerdings ohnehin lächerlich bei dem Preis. Für kleine Projekte ist es voll okay.

Es ist halt einfach eine Frage von Quantität über Qualität. In dem set sind Laveliere, Kabel für Handy und Kamera und eine solide Transportbox dabei. All diese Dinge müsste man sich bei der teureren Variante noch dazu kaufen. Dass die Tonqualität hierbei nicht auf dem Level von Røde sein kann, sagt einem der Hausverstand. Unbrauchbar ist der Ton aber meiner Meinung nach nicht. Ja, das Rauschen ist sehr präsent, aber relativ einfach entfernbar und je lauter die SprecherIn, desto egaler ist das Rauschen. Mir ist es lieber ich bekomme ein rauschiges bearbeitbares Signal, als es ist in dem Teil irgendeine komische Rauschminimierung eingebaut, mit der ales nach Blech klingt.
Nun zum Guten: Die Bedienungsanleitung kann man ignorieren. Es ist so intuitiv, dass man sie eh nicht wirklich braucht.

Wer keine hohen Ansprüche auf Tonqualität hat (aka. für Social Media Content) wird happy damit sein. Wer noch nie Tonbearbeitung gemacht hat, wird zu kämpfen haben.

Cables livrés HS
Robin38 01.04.2022
Le concept est sympa, bonne prise en main, qualité du son convenable. Mais les câbles vendus avec sont médiocres : le TRRS est HS et le TRS a un faux contact, résultat : le son fonctionne une fois sur 2 avec des bruits parasites insupportables.
