why are there only db meter from 30 db upwards?

Hi Alfred - MacBob's response is pretty much spot on. 30b is pretty much silent, your going to have a terrible time trying to locate somewhere with a reading below this level unless you are in a sound studio in which case you should probably buy a much advanced device. Anything less usually cannot be heard by the human ear very well. The cost to make a device to measure below this level would raise the price considerably. There are some out there that can read lower but you will certainly pay much more for these units.You should expect a normal "silent" room to come in at about 35-50 dba which is quite quiet.Sincerely,BAFX Products Support Hi Alfred - MacBob's response is pretty much spot on. 30b is pretty much silent, your going to have a terrible time trying to locate somewhere with a reading below this level unless you are in a sound studio in which case you should probably buy a much advanced device.

Because below 30 db is too low to be worth measuring as it would be getting close to silence. Above 90 db for extended time is what is of concern regarding potential hearing loss.

I don't know in dbs as I have no way of measuring. I have this on my car and it is loud when car is not running. When tuning I can't hear it. Hope that helps

I would ask the manufacturer. The amp had inputs for additional device connection. I only got the 30 modle with no additional add ons. Sorry. I wish I could have been more help

do you mean db?if so you may want to use the 0 db setting because the 3+db setting may be too over tinty(but if you use a good sub you may want the 3+db setting for a little more highs) remember this every 3db doubles your power(it could be too much highs for your system).but test and see what your thoughts are(try both).

Well first check you input gain but on mine the meter suddenly maxed out then dropped to nothing and hasn't worked since. That was on the first day of use. However, everything else works as it should (if a little noisy, it's not the quietest pre-amp). Since my interface has either all phantom power on or off I use the preamp for using both condenser and dynamic mics together. I don't think pinned in the red is normal.

This isn't the tool you want for just measuring volume. Get a Radio Shack Db meter for that.

I have an output amplifier (DJ Stuff) that I use anyway so I didn't notice anything flat. Try boosting you Bass setting in yours computers EQ

You need a way to measure decibels (db). Either a DB Meter or a part of your recording program. There are acceptable limits for the human ear.

It depends - (I hate it when someone says that; bear with me.) The meter features a gain control for each channel. That said, you are asking about "rise time" or the needle ballistics for mechanical meters. This factor is relevant in understanding why not all meters seem to respond in the same way. First, set up a test tone on your audio console/mixer/source and calibrate its local meter to -12dB, the digital standard, or 0VU, the analog standard. Set the input levels to any recorders connected to your mixer in the same way. Set your AmAudio Meters to just illuminate the -12dB red LED. Now you have everything calibrated for "static gain". This is step one in managing your studio's "gain plan". Now, play some pulsing music or just "pip" the tone on/off to analyze the ballistics behaviors of all your meters and learn about the differences in rise/response times. Meters with zero response time are peak readers. Example: A hard single piano note can have a 10dB difference between RMS and peak readings. Normal speech "envelope" has roughly 1.5 to 2dB of difference. Hope this is all helpful.

This mini sound level meters comes with 31.5Hz ~ 8KHz frequencey range and 40~130dB, and A frequency Weighting. Hope this information is helpful to you.

This is 100% incorrect, something Monster just made up to sell more cable. If you're getting hum then it's something else in your system.

I don't know why you couldn't do that, though there may be other meters more appropriate to that application. Because the meter is very sensitive it will provide you with either the "Min" or "Max" dba it reads. That may not be the skateboard. It could be a measurement of some other ambient sound. You get the dba reading for only one sound each time you turn it on.

Yes, or any other of the jacks that you might have. That's all I did and it works just fine. I don't like the volume thing because there is no level meter so you just kinda have to guess.

If you are going to use a measurement mic, the computer program or the frequency spectrum could provide the pre-amplification that you need. it is more accurate if there is no pre-amplification in the input.

Normal conversation level is about 60dB. This is a great meter for the price. Mine works well.

Hello and yes, a reduction of 29 Db. The reason I bought these is because I have used them at work for the last 30 years and they do the job! I've tried different types, kinds and these work the best.

There is an amp adjustment, but it can't be turned down low enough for me either. Must have been made for the really, really deaf :-(
