d&b audiotechnik 30D - Signal Monitoring (Scope); Scope Functionality and Application Examples

Recall: Recalls the settings of a stored preset.
Store: Stores the current amplifier settings to the selected
preset memory.
Clear: The selected preset memory is cleared and «(empty)»
is displayed on the «Name» button.
Note: Choosing one of these functions, a corresponding
confirmation dialog will be issued to allow either confirmation
of the selection or to cancel the action by selecting the Back
button (
).
12.5.6. Scope
The «Scope» function allows basic signal monitoring of the
amplifier's output voltage (full color) and output current (light
color).
Select
A U, I
Output voltage and current of channel A.
B U, I Output voltage and current of channel B.
C U, I Output voltage and current of channel C.
D U, I Output voltage and current of channel D.
All U Output voltage of all channels.
All I Output current of all channels.
All U, I Output voltage and current of all channels.
Y scale
Scale of the measuring values in FS (Full Scale). 1.0 FS represents
the maximum output voltage or output current.
Application examples
The scope function is a useful tool for ...:
▪ determining the signal quality.
▪ determining a phase shift between the channels.
▪ getting a rough impression of the crest factor.
▪ checking the output channels (e.g. no output current
displayed Þ the connector cable may be interrupted or no
loudspeaker is connected.
▪ checking the power amplifier (e.g. no output voltage
displayed).
