The range of the Audio Meter is –52 dBFS to 0 dBFS.The lines and colors indicate danger of clipping, as described in the table below:Line dBFS BarColorDescriptionFirst line (far left border;solid)–52 dBFS Green Audio is not clippingSecond line (solid) –20 dBFS Green Audio is not clippingThird line (dashed) –12 dBFS Yellow Audio close to clippingFourth line (dashed) –2 dBFS Red Audio is clippingFifth line (far right border;solid)0 dBFS Red Audio is clipping (if signal exceeds –1 dBFS, the whole bar isred)NOTE: In the American broadcast and post production systems, –20 dBFS roughly corresponds to 0 VU and 4 dBu. Ina digital system, dBu is an approximation; the correct unit for digital audio levels is dBFS.C O PYR I G HT © 2017 R ED.C O M , I NC 955- 0127_V6.3, R EV- M | 150RED RAVEN OPERATION GUIDE |
