XVIV U2 wireless system test

Ramage and plumage

It is in a rather classy black and silver case that I receive the U2 kit, solidly wedged in a compact foam.The accessories are succinct, double USB cable and microphone instructions for mice (myopes abstain)), but sufficient.

A quick overview of the rigorously identical transmitter and receiver housing leaves me a little hungry for manufacturing quality: everything is light, all in cheap plastic, with buttons that have a little play...The pivot of the jack nevertheless seems solid.

I quickly understand the desire of XVIV with this product: a wireless without as light and simple to implement as a cable!And from this point of view, well obliged to admit that it is rather well thought out, especially at the level of the receiver.The fact that it also works on battery and is of very compact format allows you to kill it simply and quickly in its amplifier, its sound card, or even a pedal or a pedalboard, without the need for support or an outletadditional.The load by USB (the double cable supplied allows a simultaneous load of the two units)) allows to use any computer or charger available, or to load in the rotten van which leads you to the MJC of Convieux-les-Petit-The where you will give a live of madness to the ball of hunters thanks to the cigarette lighter/USB adapter

(But I'm getting lost.))

Bien entendu cette technologie empruntée à nos téléphones portables pose exactement le même questionnement que pour ces derniers au sujet de la durée de vie des batteries non remplaçables et de la solidité de ces p**** de b**** de m***** (pardon!)) de ports micro-usb qui sont quand même une connectique passablement cheap et grand public.However, we can legitimately think that the lambda guitarist will make much less charge cycles to his Wireless than his smartphone, and that at this level the U2 will have a few years in front of him.

The active population

Trêve de Blabla, I therefore plug the 16th receiver on my sound card, and the transmitter on my guit...ah well no, not on it...If the format of the U2 makes it completely compatible with most instruments, stratocaster including, the thickness of the pivots makes it impossible with the transverse jack sockets such as those present on the ibanez saber style guitars.If you have this kind of instrument, favor wireless with a box and a mini cable!

You have big pivots, it's like sneakers, you don't come home.

I note that the lightness of the U2 boxes has an advantage, that of not weighing on the jack of materials, and therefore to avoid twists and other breaks.On the other hand, on my superstrat, I must suddenly wedge the transmitter transversely to prevent it from moving to use.

So once the Bouzins are lit, let's start with the bad news.After having supposed a breakdown on the model in my possession, an internet tour confirms to me that it is in the design of the U2: it does not work with active electronics.But like, not at all, with none of my shovels with preamp, nor the bass.We have a constant crime that increases if we pass the hand above the electronics or the transmitter...

This is a shame because it is in my opinion little thing, a shielding or a mass to be corrected...Finally, as Gaston would say, with passive instruments no problem on the other hand.

Suddenly, the comparative test is not very speaking because like most HF, the XVIV acts as buffer and delivers in the sound chain a low impedance signal.In the comparison sound extract, I therefore had to re-harmonize the gains between the wireless track and the version with the passive guitar in my reference cable (Sommer Colonel Incredible, 3m))

What we can still see is that the rendering is not dull and does not seem to lack frequencies, with even a hint of biting in addition in the treble/high mediums compared to the cable.The dynamics are rather well respected, and after having mourned my active guitars I enjoyed playing a good hour with the 17th century!As with all digital HFs, I did not find a dropout with the distance, nor audible latency.From this point of view, technology has still made much progress from the UHF/VHF where it was necessary to put minimum 500 Euroboules to have something drinking!

Conclusion of the XVIV U2 wireless system

The bet to offer at an ultra attractive price an extremely simple wireless to implement while delivering good sound quality is completely won.Some youth flaws and a potential lifespan that remains to be tested do not spoil pleasure, but make you carefully check that the XVIV U2 corresponds to your need and be compatible with your gear.If so, go for wireless freedom, free love and total nudity!

Hum...I have to stop getting carried away, me.
