How to express a loss as a gain in dB?

If any system show a 6 dB loss, can we express like below? **** The system has a loss of -6 dB***** (i.e. The system has a loss of minus 6 dB) I believe -6 dB loss is 6 dB gain. So the above expression is wrong. Am I right?

Decibel is what sound is rated in.

The sound level is expressed as a line.

0 in the middle.
Negative values are to the left, Positive values to the right.

Less DB rating to the Left, more DB to the Right.

Anything above the 0 is louder. 1, 2, 3, 4, 5, 6, etc.
Anything below the 0 is not as loud, -1, -2, -3, -4, -5, -6, etc.

It would be correct to state a 6 DB loss as -6DB.

Static Noise


Is it a hissing noise or a distorted crackling noise? If it's a hissing noise then it's due to a bug in Windows that adds 30 dB of gain. It's easy to work around, though: Go into Recording devices, Properties button, Levels tab, right click on the level number so that it shows in decibels, and then adjust the level to 0 dB. It's supposed to be at 0 dB but Windows 7 defaults it to 30 dB for no reason. This isn't a problem on Windows XP or OS X.

Check the cables. If one lead of an XLR-XLR cable is shorted to ground, 6 DB gain is lost. You haven't really supplied enough information regarding cables and model of the manual mixer for us to help much. Do check that ALL of your audio interconnections are BALANCED lines either XLR to XLR or TRS cables. Grounding one side of a balanced line reduces gain 6 DB. Try swapping mic cables and channels to test where the problem is in the system.

Soundcraft Gigrac 1000st distortion in the mic inputs. The rca line in is fine and clean. No effects on the mic pre sounds like its breaking up at any volume level. really dissapointing.


You should be using Dynamic mics such as a Shure SM58. They go into the first FOUR channels and if there is excessive gain and distortion, push in thee Pad button below the connector for those four channels. Inexpensive consumer microphones used with some Karaoke home systems are not suitable for this unit. You should be using XLR cables on the mics (balanced lines). The Pad buttons reduce the gain by a fixed amount of -20 Db for mics that have too much output to be controlled by the gain controls right above the connector. Ideally those should be no less than 12 o'cloock for good signala to noise ratio. Additional channels beyond the first four do not have as much gain and they do not have the -20 Db pad option.

Is the bass boost the gain or frequency knob?


Bass boost simply adds DB or gain to the bass signal. Some like it, some dont.
The frequency knob is the Low Pass Filter (LPF) that cuts off the amp output above
the set frequency. A bass system usually cuts off below 400 HZ and more often 200HZ.
A good, rattle your car bass note is in the 25-80HZ range or lower but most amps and audio
input devices cant attain a good low note with clarity.
"Low-pass filter allows only frequencies below the crossover point to be amplified. A high-pass filter allows only frequencies above the crossover point to be amplified - useful for keeping low bass away from small speakers, so they can play more efficiently."

Loss of Nero Express 6.0


Restore your pc to a previous date. One before you started the update. Click start, click accessories, choose system tools, click restore, choose restore my computer to an earlier time, click next, choose date earlier than update, click next. pc will return to status of that date and should be good to go. Restore will run on it's own, be patient, don't panic. Good luck.

The PGX1 bodypack has a switch on the side to set the gain. Make certain that switch is in the "mic" position. Otherwise, simply turn up the volume on your mixer.
