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 ( ).
9.5.6. 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).
