Information on the supported frequency ranges

Here you can see which frequencies are supported by this wireless system and the countries in which these frequencies are allowed in the future for wireless applications.

Quite an awful experience
Andypoo 09.06.2020
I bought two of these units along with an antenna splitter to build out a 4-wireless channel system for a school.

On paper, they look great. Wide frequency range support, configurability, etc.

Once I got them in hand, the problems started to become clear. The units are extremely plasticcy. Right down to the clip. I doubt they would last very long in any shared-use environment. Also, the transmitters have a power button and then a large, external volume knob. Which doesn't feel great and would be easily knocked. (I don't like anybody changing their gain like this - this was bad research on my part - as it should have been obvious from the pictures).

But things only got worse when I started to set them up. I used by usual method of spacing out the wireless frequencies (which was an odd experience, as this set has groups and channels, but both groups and channels simply are small increments of the frequency range. I couldn't find any further information if this grouping was due to frequency reflections or also why only 4 systems are recommended in the range. This led me to write to Thomann who reassured me that I could just stack the units one or two frequency ranges apart (which seems very strange that they would only recommend 4 systems in such a wide frequency range).

Nevertheless, I persisted however it became immediately obvious that different transmitters, even in totally different frequency ranges, would start to interfere with one another when they were near to one another.

Sometimes I even managed to get clear signals on unrelated frequencies when the units were too close together.

I eventually managed to find some frequencies that seemed to work and spaced the units apart. Then I went to take them to our venue. In our initial day of testing, we had drop-outs and frequency hazing, volume level issues, etc for an hour before we had to abandon the units.

Switched back to one of my personal Samson Concert 88 units with the same headset, and it was working fine - no dropouts, volume level stuttering, or other issues.

Have requested the units to be returned. I really hate to have to return anything, but I really just can't use these units for anything and can't recommend them to anybody. Unfortunate, as they look great on paper.


Good value wireless mic bodypacks and receiver

We use these in church. They give good quality sound for the price, and we appreciate the space saved by having 2x mics but only one receiver. Very easy to setup.

Para algo sin muchas pretensiones

Si buscas calidad de sonido no es lo suyo. Yo lo uso para teatro de calle en espectáculos pequeños que no necesito calidad de sonido, porque el equipo es pequeño y tampoco se va a notar. Pero para algo así es válido, no para cantar porque ya no recogerá matices (también depende del micro, pero he notado que uno de los canales suena peor que el otro. Algo muy práctico es que si los conectas con un cable Jack salen los dos micros por un canal de la mesa (esto ha ce que no puedas ecualizar los dos, eso hay que tenerlo en cuenta, y así se agranda el problema de que uno suene peor que el otro)
Yo creo que el uso es para voz hablada para aforos pequeños. Las petacas no tienen una fabricación que de seguridad, mucho plástico y la pinza no es muy buena, yo los meto en un bolsito porque no me fío.
En resumen, para algo sencillo y sin pretensiones. Yo los tengo como micros de reserva.

Köpte denna produkt och för det första var den inte helt solklar att rackmontera. Gummifötterna var tvungen att plockas bort och gick lätt sönder. Förstod aldrig hur dom tänkte att antennerna skulle monteras i rackvinkeln. Visst, det finns färdiga hål men jag fick köpa en BNC hona-hona och hitta på en egen variant för att få det å sitta ordentligt. Kanske jag missade att det krävs något mer (special BCN kontakt?) som ska då passa i hålet.
Men döm om min besvikelse när jag testar mina elguror (både aktiva och passiva mickar) och det hörs ett rejält "poff" i P:A?t när jag byter mickar med switchen. Enligt Thomann är denna produkt inte avsedd för detta vilket låter riktigt konstigt för mig. Står ingenstans i produktbeskrivningen. Den tappade också helt signal om man spelar mjukt på guran. Men jag menar...en ballad...ska man tvingas att spela aggressivt och dessutom absolut INTE switcha mellan mickarna. Nä - denna produkt åkte raka vägen tillbaka. Funkar säkert bra med andra instrument men i ett rockband var den helt förkastlig. Thomann rekommenderade "the t.bone free solo Twin PT 823 MHz" istället som kostar 1000 lappen mer. Får se om jag vågar mig på denna!
