Mode Control (Register R2)
The Mode Control (Register R2) section, which is associated
with Control Register R2, contains a collection of unrelated
settings, including current and thermal fault recovery, mixers,
and emissions control modes.
Current/Thermal Fault Recovery
The Overcurrent Autorecovery and Overtemperature
Autorecovery check boxes control the autorecovery feature
of the fault detection mode. When selected, the autorecovery
feature is active. When cleared, the device stays in fault
protection mode until the reset register, R8, is written to zero
or the device loses power.
Mixer Modes
When R-to-L Signal Mix is selected, the right input signal is
mixed to both right and left outputs. When L-to-R Signal Mix
is selected, the left input signal is mixed to both left and right
outputs.
Edge Speed
Several different emission control mode levels can be set. The
slowest setting yields the best emission suppression, but it may
degrade SNR and efficiency measurements slightly.
Error (Register R6)
This section is associated with Control Register R6. Each block
is a read-only indicator that is activated when a particular fault
condition is encountered. It does not update unless the R6 Read
button is clicked, as detailed in the Direct I
section. This feature is only active if the fault recovery options
(overcurrent autorecovery and overtemperature autorecovery)
are enabled.
