Swiff Audio WS-70+ Wireless System

This is a really well-made product that will suit the needs of many players out there, who mainly play single notes or power chords. If you are playing through distortion pedals and loud amps, this will be a great product for you. The packaging, unboxing, ease- of-use features etc. are impressive too.

Where the product falls behind though, is when it comes to playing styles that involve dynamics and finesse.

NOISE GATE:
There is a slight gating effect that cuts out softly sustained notes -- it's not extreme, but it's there and clean notes and chords might not ring the same way. It also blocks subtle feedback effects, and can ruin sensitive playing styles.

COMPRESSION:
There is also a certain amount of compression and audio-frequency tunneling. This changes the dynamics of combined notes and how they interact with each other and how they are ultimately rendered and perceived. Wide intervallic combinations are not great. A low note combined with a high note will not render like it should. Cleanly played Hendrix chords or Jazz chords will sound a bit off. If you are a player who likes subtle harmonics and overtones, this is really not the product for you. The low E-string will not twang the right way when struck hard. Combined notes will not create the right timbre.

LATENCY & FREQUENCY BAND
There is no perceived latency. Transmission and reception is great. No interference whatsoever. It's great for avoiding busy WiFi bands, cuts through human bodies and furniture and has quite a decent range for it's size and power.

"STEREO TRANSMISSION" -- BONUS FEATURE
Another great bonus feature is that you can unscrew the mono jack to reveal a mini-stereo jack. This allows for you to transmit music from your iPad to the house PA system, for example. It's not super-HiFi or genuine stereo transmission, but I've tested the sound and it's decent enough for a noisy club, if you ever need to play some music between sets. All you need is buy a cable like the "Pro snake TPY 2005 WRR" (available through Thomann) and connect it to the receiving unit.

CONCLUSION
This is not a super-deluxe product, but has an incredible cost/value ratio. I'm just a fussy audiophile who works a lot with intervallic notes and clean dynamics, so it's not great for my sensitive style. However, I will be keeping this product so I can use it for sound checking from various locations in a club, and for piping music from my iPad to the house system between sets. For its price, its a keeper.

Chargement par usb C avec câble usb-A vers 2x usb-c fourni. Je l.ai testé avec une guitare electro-acoustique et un violon électro-acoustique et ça fonctionne très bien. Je l’ai acheté parce que j’en avais marre que mon précédent système en 2.4 g soit en conflit avec les wi-fi des établissements où je jouais. La connection se fait en uhf. C’est le type de connection des systèmes pro qui n’utilisent pas le 2.4 ni le 5.8 car ce sont les bandes passantes des wi-fi des box internet. Ce type de connexion est bien plus stable et porte plus loin et de manière plus fiable. Seulement, ce n’est pas la mode. Le son me parait plutôt bon et je n’ai pas trouvé de différence notoire avec mon câble de 3m. Et le prix on en parle ? Pour moi le rapport qualité prix est génial.

Gekauft für den Live-Einsatz, als Gitarrensender.
Leider hier schon das erste Problem. In der Anleitung steht nicht wie man den Channel wechselt, wenn z.B. 2 Gitarristen mit dem gleichen Sender arbeiten.

Dann das schlimmste überhaupt... Der Empfänger geht während des Gigs aus, weil der Akku leer wurde.
Das konnte eigentlich gar nicht möglich sein, denn vorher wurden sie voll geladen und in den Spielpausen wurden beide Geräte geladen.

Klangverfärbungen macht er ebenfalls. Mit Sender muss man deutlich mehr Gain herrein drehen und die Lautstärke erhöhen...

Fazit: Keine Kaufempfehlung!
