red when the audio level exceeds this range. The range starts at the set reference level

and changes in 1 dB increments.

Analog and Digital Scales

The Analog and Digital Scales submenus are used to determine the type of scale that

appears on the audio meter display.

Meter Response

Ballistics specifications are shown in Table 4-14. These specifications describe meter

scale markings and both attack and decay times for meter movement.

The audio scales and ballistics are based on the IEC 268-10 and IEC 268-17 standards.

These standards describe meter scale markings and both attack and decay times for

meter movement.

• VU (NORMAL)

• PEAK

• TRUE PEAK
