As a professional recording engineer, I have used many different talk-back solutions over the last 30 years. From an old tape recorder with the Rec/Play buttons pressed, to an iPhone app which is not available anymore.
The Studio-Q is a well constructed solid unit, it oozes quality.
It is a perfect talk-back for mobile studio use. I record in many different venues and this little box of wonders is perfect.
I connect a light to its 12v output so the musicians know when the producer/engineer is talking and a latching foot switch to enable hands free use.
All in all it is a super addition to any studio scenario. The quality of build is fantastic with solid connectors which feel high end.
The one I received had multiple location plug adapters for the power transformer. So I slipped on the UK one. Works a treat.
If you are in need for a small but high quality talk-back solution then Studio-Q is the way to go.
I dropped a star for features as a latching switch on the unit would be of use, however I do use a latching foot switch so no biggy.
