Douk Audio VU22 Dubbele analoge VU-meter display, DB-paneel, muziekspectrum, MIC en LINE geluidsniveaumeter, audio-indicator

Très bon produit

Wer braucht schon ein VU – Meter für sein Hifi/Cinema Setup? Na, ich. :-)Sehr gute Verarbeitungsqualität. Empfindlichkeit über das eingebaute Mikro ist top. Farben und Helligkeit ebenfalls. Klare Kaufempfehlung.

I had issues getting my equalized preamp signal up to the correct level to drive my audio power amplifier to its max. The Douk VU22 is what I needed, I got the one with the thick silver panel. It's a classic use for a VU meter, showing how hard I am driving the power amp. I can now verify by measurement that the input signal stays below the limit while watching it. And I am secure that I won't be blowing fuses or voice coils or frying anything. It's great!Oh it has some entertainment value too. I'm not using the dancing light show. But that is pretty cool.Maybe if you are running classic analog stereo gear to blast streaming digital music, you noticed that the significance of 0 dB input level is different now. Mainly because digital equipment refers to dB full-scale or dBFS, and zero is its 'hard maximum'. Then it is very easy to hear if you go over 0 dBFS, because all peaks sound awfully distorted. So you would never go beyond 0 dB input on the meters, or even touch it. (That's like 1.12 volts RMS.)With my old consumer gear, transistors or vacuum tubes, the dB term refers to voltage, dBV. One might want the input signal to run as high as +3 dB at peaks. That's 1.59 volts RMS. There may be a bit of even harmonic distortion on the peak, but you can push it without sounding bad. There is more signal headroom available, than on the new equipment.In any case, it depends on what is the rated input sensitivity, for the power amp to deliver its rated output.This VU22 measurement display device allows you to adjust your signal level to whatever the amplifier will bear, without exceeding it. It does not have any signal adjustment capability of its own, no boost or cut.If I did not already have a line-level signal-matching amplifier, I would have bought a Douk EQ5. The VU22 is sort of like the top meter-half of that unit, and just what I needed. (I might eventually get an EQ5 anyway. This is good solid gear. Looks great, feels great, sounds great.)I was looking to drive my power amp with an input signal up to 1.26 volts RMS, to get to my amp specification point. I measured the VU22 will put out this voltage when the meter says +1 dB. Problem solved. Watch the needle. Rock on.I simply adjust my preamp for different signal sources, until the meters show the signal into the power amp is bumping the mark at +1 dB = 1.26 VRMS. Then I can also run it up to +3 dB if I feel like it, no worries. Your required amp input signal will likely be different than this. (Unless you also have a Dynaco ST-70.) You will need to pay attention to whatever number your amp specs say.But the VU22 will tell you where you are, relative to your amp signal specs. It helps me avoid any unauthorized smoke.(Studio gear is different, will distort sooner, past ~1.2 VRMS. So I hate running into complicated stuff like old specs based on telegraphs, but my eclectic museum collection needs inputs that max-out at 1.26 to 1.59 volts RMS. (+1 to +3 on the VU22 meter.) Most folks likely need to measure only 1.12 volts max, or -0 on the meter.)OK, so here are the signal levels I found my meters were calibrated to display:(I set the meter in Red Mode with the VU22 meter display knob set at 'Max', then measured how much signal did it take, to get to a reading of 0 dBV, and each step beyond.)VU22 meter reading = Volts RMS signal0 dB = 1.12 v+1 dB = 1.26 v+2 dB = 1.42 v+3 dB = 1.59 v+4 dB = 1.78 v+5 dB = 2 vWow, I had a Sony Blu Ray that put out 2 VRMS and would overdrive all my analog stuff even without a preamp! (I bet that would totally overdrive a digital input, without an attenuator.) Then I could not quite hear my phono preamp output. Decided I needed to sort out all these different signal specs and odd units. Ended up with a small line matching amp and a Douk VU22 and a year later the combo still works great, sounds great.And the bouncing-needle meter movements or light-shows just add a retro touch of Frankenstein-Edison character to the museum equipment, while I confirm my signal maximums. Turn it up!

Para que sirve no mucho solo verse hermoso y ajustarlo para visualizar el nivel de audio en el entorno y se ajusta ganancia y colores, solo con usb, lo mejor lo conectas por canales RCA que no le voy mucho y tiene micrófono 🎤 así capta todo. Si tienes tu desktop, lap, media center este es un accesorio genial

Très très bien
