Figure 15: The 764 Level Meters
(1)
Meter Ballistics (i.e., dynamic response, or attack/decay character-
istics of the meters). The meters can emulate the dynamic re-
sponse of three common types of analog audio level meter.
Choices are VU with the scale extended to permit display of true
peaks on the same bar; PPM, a quasi-peak meter with 10 ms in-
tegration time and slow decay; and True Peak, with instantaneous
response and slow decay.

Scale Units (dBFS or dBr). By default, the zero dB mark is at digital
full scale, and units are in dB relative to full scale (dBFS). You
may also set the 0 dB mark to either the Peak Program level or
the Test level—see items (3) and (4) below. In either case, the
scale units are dB relative to the specified zero point (dBr).
