If you own a digital microphone, you may have wondered what that little dial labeled “gain” is supposed to be for. Even when you find out that gain determines how loud sound volume is, it is often difficult to set properly.
The gain dial usually isn’t numbered, so you aren’t alone if you have ever struggled to find the proper audio setting. Factors like where you stand and how loud you speak affect the gain. With good recording software, you can monitor the microphone’s sound level and make adjustments to set the perfect sound levels for the show.
Mic Level and Line Level
However, professional audio equipment works with audio signals that are at line level, which is nominally +4 db. Notable “Professional equipment” includes mixing consoles and digital audio workstations.
Note that mic and line levels are both just average nominal values. the particular values of those levels from a microphone vary on the sound source loudness, the space of the microphone thereto sound source, the sensitivity of the microphone, the quantity of gain applied thereto microphone signal, and other factors.
Line level is usually thought of as being around 1,000 times stronger than mic level. we need gain to spice up these mic level signals up to line level in order that they’re compatible with other professional audio equipment. From our general nominal values noted above, a 44 dB to 64 dB gain boost would do the trick.
How to set mic gain on a sound mixer
This is one among the most common questions asked by both beginners and even experienced sound technicians, whether working within churches or gig venues. An appropriate gain setting for all inputs could also be a crucial think about creating the foremost effective mix possible. This means that every one signals coming into the mixer are at equivalent levels.
Setting the gain for each input channel appropriately ensures that nobody input overwhelms the mixer. also ensures that the lowest possible background level is achieved from every input. The gain could also be explained as mic’s sensitivity. it’ll increase the potency of what the microphone will pick-up/hear, and is employed to manage the acceptable intensity of each instrument.
Setting Mixer Gain Level – Things to think about
-Too much gain and thus the signal will clip and warp . insufficient gain and thus the signal feels weak and noisy. You’ll be ready to boost the fader up as high as you’d like however if the trim is off, you’ll get nothing but noise. On the opposite hand, if you set the trim high and also the fader way down, possibilities for distortion are much higher.
-If you’d wish to extend the quantity of a sign , you want to reach for the channel fader, not the gain knob.
-Every mixer is completely different; however, this is often typically where the signal turns from green to yellow or orange. simply make sure you keep it out of the red!
-To set the gain for a channel, have the musician begin playing their instrument, and with the channel fader down, slowly happen the gain knob and keep signal below traffic light on the mixer
-After setting the amount on the preamp, slowly mention the channel fader until the instrument is at the acceptable volume.
-For loud environments like noisy clubs, concerts etc., close mic-Ing is typically the right thanks to achieve the foremost from your sound source.
How to adjust the gain
Way back within the day, once we visited studios to record, the engineer would say “give me a touch bit for levels.” Now you’re the engineer. So, offer you a touch bit for levels. Here’s what you do:
• Set the gain knob at about 2 o’clock.
• Hit record.
• Speak at the loudness you’re actually getting to use at the mic distance you’re getting to be at.
• If the recording level (the waveform) is to low, happen the gain
• If the recording level is just too high, turn down the gain.
