METERS

The XT20 provides two buttons for meter display options: [PEAK MODE] and

[PEAK CLEAR].

PEAK MODE BUTTON

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.

PEAK CLEAR BUTTON

The [PEAK CLEAR] button is used to remove any track peak LED

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.

FINE METER MODE

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:

❿ 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. The

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.
