Peak + VU In Peak + VU mode, the perceived loudness (or VU) is simultaneously
displayed as a standard bar while the peak signal is displayed as a single,
independent segment above the VU. By default, meter ballistics is set to
Peak + VU.
Peak Only Peak-reading ballistics (PPM) correspond to actual signal peaks, but do not
necessarily correspond to perceived signal loudness. Peak meters have an
instantaneous attack and a slow decay to allow visual monitoring of peak
activity. Peak metering is useful in digital audio workflows. In the digital
realm, signal overload can cause immediate distortion.
Setting Peak Hold
When meter ballistics is set to Peak + VU or Peak Only, peak hold displays the
last highest peak value on the meter as a separate, individual meter segment.
By default, this meter segment will remain visible for 1 second. This time frame
is called the Peak Hold, and it may be adjusted or disabled altogether.
To modify the Peak Hold time for meters:
1. Press the MENU button.
2. Turn and press the Headphone encoder to select SYSTEM > Meter Peak Hold
Time.

time, from 1 to 5 seconds.

until a higher peak is reached.
Off Does not hold peak values.
Setting up Date and Time Parameters
Properly setting the time and date is important for file metadata, file system
functioning, and some timecode functions. Setting the correct GMT time zone
and daylight savings values is also vital for correct data stamping on the exFAT
file system.
The 664 has several System settings related to date and time parameters:
