What does line level audio mean?
Line level refers to the typical level (strength or amplitude) of the audio signal from mixers, signal-processing equipment and other consumer and professional audio gear. There are two line level types: consumer and professional.
What is line in on sound card?
What Does Line In Mean? Line in is the audio jack found on an audio device that can be used to connect to another audio output device or microphone. Line in could be either digital or analog. The core functionality of the line-in jack is to aid in audio recording or manipulate the incoming audio.
What is louder mic or line level?
Matching Levels
Connecting a line-level source to a mic-level input will cause the sound to be loud and distorted because the line-level signal is much stronger than what the mic input will accept.
What is line level in dB?
What is Line Level? A line level signal is approximately one volt, or about 1,000 times greater than a mic level signal. One volt is also expressed as 0 dBV – so a line level signal is about 40 to 60 dB higher than mic level.
What is the purpose of line level?
Line levels (or “string” levels) are a special brand of spirit level used for leveling across longer distances. They can be attached to a tightly pulled string to find level between two stakes in the ground to find level ground.
What is a good audio level?
Ideal Audio Levels
The overall audio level should be in the -12 to -6dB (decibel) range, especially during dialogue. The audio meter will turn yellow in this range. Some parts of the audio will be louder or quieter than this, but the goal is that the majority of the audio settle into the above range.
Is line level balanced or unbalanced?
unbalanced
The line in/out connections on consumer-oriented audio equipment are typically unbalanced, with a 3.5 mm (0.14 inch, but commonly called “eighth inch”) 3-conductor TRS minijack connector providing ground, left channel, and right channel, or stereo RCA jacks.
What is a line level cable?
Line level is the specified strength of an audio signal used to transmit analog sound between audio components such as CD and DVD players, television sets, audio amplifiers, and mixing consoles.
Should I use line in or mic in?
Mic-in is used for directly plugging in microphones, and line-in is for consumer and pro-grade gear. Mic-level signals are weak and line-level signals are strong. Mic inputs use a female XLR connector. Line inputs require RCA, ¼” phone jack, or 3.5 mm phone jack.
What output is line level?
Line level is the loudest signal we handle in audio. In terms of voltage, it comes in at approximately 1 volt, or 0 dBV. Line level usually flows through the system after the preamp stage and before the output to our speakers.
How do you read a line level?

What dB should I set my speakers?
As a general rule speakers should be set between 70-80 dB in volume. This can be established using a decibel meter. Several variables impact this, including the position of the speakers, the distance between them, and the acoustics of the room.
What is the difference between line and mic level?
Line-in and mic-in are audio inputs but they are indicative of the voltage level of the audio signal. Line-in can handle strong (think loud) currents whereas a mic-in can handle very low level of currents. With audio signals, sound is transferred as a voltage into our mixers, audio interfaces, amplifiers, and speakers.
What is a normal sound level?
about 60 dB
Common Sources of Noise and Decibel Levels
A whisper is about 30 dB, normal conversation is about 60 dB, and a motorcycle engine running is about 95 dB. Noise above 70 dB over a prolonged period of time may start to damage your hearing. Loud noise above 120 dB can cause immediate harm to your ears.
What is the standard level for professional audio?
+4 dBu
The line level standard for professional audio is +4 dBu, which is about 12 dB greater than the consumer line level standard of -10 dBV. The difference between them is actually about 12 dB.
Is 600 ohm a line level?
Line outputs usually present a source impedance of 100 to 600 ohms. The voltage can reach 2 volts peak-to-peak with levels referenced to −10 dBV (300 mV) at 10 kΩ. The frequency response of most modern equipment is advertised as at least 20 Hz to 20 kHz, which corresponds to the conventional range of human hearing.
Can I use a instrument cable as a line level?
There are no safety issues here. You can use either type of cable with either strength of output with no danger whatsoever. The advantage of the balanced output is that you can run your line over long distances when you use balanced cables.
How does a line level work?
Can I use line in for speakers?
You cannot get speakers to work by plugging them into your line in jack, no. A headphones/speakers jack, or a line out jack, will work. Like a microphone jack, a line in jack is for capturing audio–you would plug a device in that sends a sound signal to your computer, not the other way around.
What is the difference between line level input and speaker level input?
Line-level signals refer to the output voltage of an audio device, whereas speaker-level signals refer to the final output that the amplifier feeds into the speakers.
How do you set a level string line?
Secure the string to one side or corner of the area you want leveled. Attach the line level to the middle of the string using the small hooks on the line level. Pull the string tight while sliding the level up the string within eyeshot. Pull tightly enough to avoid any sag in the string.

What is the perfect dB?
If It Sounds Too Loud, It Is Too Loud. Decibels are the unit of measurement for sound, abbreviated dB. Sounds at or below 70 dB are considered safe for our hearing. That’s the sound of a normal conversation between two people. Sounds at 80 or 85 dB will damage hearing over time.
Does 0 dB mean no sound?
Remember that decibels measure a ratio. 0 dB occurs when you take the log of a ratio of 1 (log 1 = 0). So 0 dB does not mean no sound, it means a sound level where the sound pressure is equal to that of the reference level.
