Dynamics:

- Using/creating dynamic range

- Amplitude/level variation 

 

 

*2 Types of Dynamics==> External Level Variation & Internal Dynamic (Signal Envelope)

 

 

 

1. External Level Variation

Meters (for measurement of External Level Variation):

 

1. V.U. Meter (Volume Unit)

- An averaging meter reads the average levels

- Not the actual level of the signal (strength meter)

▲ Volume Unit Meter



 

 

2. Peak Meter

- Read absolute level (Not a average level)

▲ Peak Meter



 

 

3. PPM (Peak Program Meter)

- Read both absolute & average level

▲ Peak Program Meter



 

 

4. Digital Meter

- Digital ‘0’ = MOL (Maximum Operating Level)

- Accepted ROL Level = -18  

▲ Digital Meter



*Basically 2 ~ 4 are same things (except VU meter)

 

*Digital level gives more freedom than analog does in controlling
