POSSIBLE SYSTEM CONFIGURATIONS
The R275HC can be configured for large autoformer-
based volume control systems/speaker selectors. When
using the R275HC for this application, set the Low Cut
switch to the “On” position. Turning this filter “on”
enables a filter that reduces the low frequency energy
which protects the volume controls/speaker selectors
and increases the efficiency of the system.
