Rated 5 out of 5 by from Good ol', Little Digital Sound MeterI bought this mini digital sound meter for a few different reasons. I use it for equalization, setting balance correctly, matching woofer & tweeter pairs & checking dB of finished audio projects. All the features work fine & I never have a problem with getting false readings with this unit. I liked that the LCD screen has backlighting & can be seen in dark areas very easy when sound testing. The only thing that I didn't like is the foam mic cover falls off easy. I fixed this by using a o-ring I slid down the mic shaft & left it in the center of the shaft & then slide the foam mic cover back on. It keeps the foam mic cover in place nicely & doesn't make the sound meter produce any false readings with it on there. I like to use it on friends audio equipment in there home to sett-up there stereos & home theaters correctly & make it sound its best. Plus, you can prove to your friends finally who has the loudest custom sound system or custom powered subwoofer, or store boughten products. Its also good to have to show when people are being to loud, like parties & other events where sound levels have to be keep to a certain level. I like the unit & will be purchasing more for friends. It product works great & is low cost ( I got mine on sale for $16.88 at the time ) & would recommend this product to anyone who doesn't need a pro level sound meter or have to pay much for a good quality sound meter.

Rated 5 out of 5 by from Excellent performance at a bargain priceI bought this meter to use as part of a hearing safety demonstration. It has very simple instructions and it is solidly reliable. Can't beat this price!

Rated 5 out of 5 by from Great value.At such a low price, it's not reasonable to expect a perfectly calibrated piece of equipment, but this one certainly seems to give readings which closely reflect real-world conditions, and works just as advertised. Therefore, a steal.

Rated 3 out of 5 by from OK for the right useI bought this for a specific purpose: to balance a bi-amped system. All I needed to do was adjust the XO so that both sections produced the same SPL at the XO freq. For this, it was fine. When I checked the frequency response - just for the heck of it - it was terrible, so the unti is no good for determining freq. response of a speaker, etc.Know what you want it to do before buying.

Does Parts express have a external power supply that can be used instead of a battery on this unit?

Asked by: Jamesg
Any 9VDC power supply will work but it will require hard wiring which will void the warranty. The one below will work well.

Can we take report from the unit, for the number of test done

Asked by: Rgraf
Unfortunately no, this will only allow for minimum and maximum readings taken one at a time, it has no real memory.
