The [PEAK MODE] button selects the peak hold mode of the eight
level meters. Each time the [PEAK MODE] button is pressed, the peak
meters switch between three possible Peak Hold modes: Continuous,
Momentary and Off. The currently selected mode may be determined by
observing the peak meters themselves.
•
Continuous: Each track's peak LED indicator will remain lit,
until the [PEAK CLEAR] button is pressed, or the Peak Mode is
changed.
•
Momentary: Each track's peak LED indicator will remain lit
for about two seconds.
•
Off: No peak indicators will be held on any tracks.

indicators which remain lit while either Continuous or Momentary
Peak Mode is selected (see above). This button will have no effect if the
Peak Mode is turned Off.

The XT20 provides a special mode which rescales the peak meters for
more specific readings. This is necessary when making very fine level
adjustments, such as when recording test tones. When Fine Meter mode
is enabled, the meters are rescaled around a center point of -15 dB
(middle point of the meters) and goes plus and minus from there in .5 dB
increments. This means the -15 dB icon will be the only level marking
that is correct in this mode. The meters' actual range will be from -18.0
dB to -12.5 dB. However, the MAX icon at the top of each meter will
still indicate clipping.
To activate Fine Meter mode:
Simultaneously press both [PEAK MODE] and [PEAK CLEAR]
buttons.
The TIME counter will momentarily display "FinE db" and the dB
stepped markings will appear on the left side of the meters.
FINE dB icon will turn on.
To exit Fine Meter mode, press either [PEAK MODE] or [PEAK
CLEAR].
The dB stepped markings and icon will turn off.
