Very useful signal tester. When you have a kit of XLR-adapters available, you can test basically any sound gear.

Only small bad thing is that PSU option would be nice, when you don't have a spare 9v battery available.

Also I have to note that this isn't a precise instrument, when controlling a 20Hz - 20kHz range with a single pot. If you need that precision, look elsewhere.

Great little gadget.

Test all your speakers/ horns "full range" and even amps/desks/cables/etc, this little thing even helps setting up sound at gigs.

Mine had problems when it arrived, didn't work at all, the screws holding the belt clip were too long, pushing against the circuit board inside, earthing the signal, I just guessed this and removed the screws, hey presto!

I found a faulty horn in one of my PA speakers simply by plugging in and listening, BUT DO BE CAREFUL WITH YOUR EARS, one watt is enough to blow your ears as you listen closely or even not so closely, please be careful.

There's far more expensive ones but why pay more.

Naja, da ist noch Luft nach oben

Zwar stabil, aber billig gebaut. scharfkantige Gürtelklemme und die Batterieklappe ist ein schlechter Witz: sie wird an der einen Seite nur von der kleinen Schraube gehalten und an der anderen Seite von gar nix. Batteriefächer aus Pappe habe ich das letzte mal in den 1970ern gesehen.
Der Signalgenerator ist auch nicht so doll, da er auch an 8 Ohm ganz schnell verzerrt. Damit möchte ich keine Qualitativen Aussagen über den Zusatend von Lautsprechern ermitteln müssen. Und de Hinweis, dass die beiligenden Gummifüße eventuell färben?? Ausserhalb Chinas sollen inzwischen auch schon nicht färbende Exemplare gesichtet worden sein.
Trotzdem nützlich, könnte aber mal modernisiert werden. Und bitte: den On/Off Schalter so platzieren, das man ihn NICHT versehentlich einschalten kann.

Not as advertised.

I purchased my unit to test speakers and to ring out rooms with adjustable sinesweeps. When I got my unit, it did not generate sine sweeps from 20hz to 20khz. it went from 400hz down to 200hz and up to 20khz according to my spectrum analyzer. Inside the unit, there is a blue trimpot to adjust the oscillator range. This was off kilter. And after adjusting with my spectrum analyzer, the unit works better, but is only accurate between 32hz and 500hz. The unit does not produce a clean sine wave, since there are always 4-6 harmonic overtones 1 octave apart each other above the fundamental frequency. The sinewave looks sine-ish on a oscilloscope, but contains alot of harmonics. The amplifier on the speakon output puts out about 2,6vAC (0,4w@16ohms, 0,8w@8ohms, 1,7w@4ohms and 3,4w@2ohms), a bit under the 2,83vAC or 1 watt @ 8 ohms as advertised.

If you need accuracy, buy something else.
But for discovering room modes and low frequency resonances in a venue, and once calibrated, it's an affordable and somewhat useful tool.

If you only need something to make noise, it will make noise. Useful for troubleshooting bad speakerdrivers.
