Technical Pro DB30 1U Rack Mount dB Decibel Meter Display+8 Outlet Power Supply

Works great!,pretty awesome, would totally recommend.

I have two of these. One is connected to a vintage tape recorder, and the other is connected to an equalizer in line with my laptop which is connected to a pair of powered speakers. They both are still working flawlessly after hundreds of hours of use.

Excelente, queda muy bien con mi componente de música...

The media could not be loaded. Bought the Technical Pro DB30 to mount above my Fun Generation RTA-31. For starters, the DB30 doesn't come with the rack ears mounted, so you have to screw those on yourself. Not a big deal, but I'm not sure who would use this without a rack case since it's not the correct depth to be used in a component system. Second, its accuracy is not only BAD, it barely works at all. It randomly peaks for no apparent reason even when the signal being sent through has no difference in velocity/volume. This thing really is garbage, which is a shame since it could actually be useful if it worked as advertised.

I have very expensive equipment and as a person into technology and electronics, I tested each outlet to find out if the on off switch turns off all the outlets connected to it upon testing. I found out that the hot and neutral using the existing AC cord or reverse. I made sure it wasn’t on my end. I replaced it with a known good AC cord see photos I would recommend a recall or for the seller to ask the manufacturer to test every single cord that goes out, there is a risk of shock or damage to your equipment if you don’t.

I bought this to help me with audio mastering in my home studio. It works exactly as described, but might be a little more useful is the response time were slower. The meter moves so much that it is hard to figure out what the average level is. Still, it is useful to see peak volumes. For the money, you are not going to find anything better.

The other reviews are correct, it takes some noise to get the bars to register.If you are playing with headphones, this will NOT be an issue, as the headphone levels easily satisfy the DB threshold requirements to get the lights to work.If you are playing with speakers, you might have to get a little loud for it to show up.You theoretically could connect the input for this from a multi-channel amplifier, amp this channel to max, and just not have any output for this particular channel.

Awesome
