Note: The SureSet™feature utilizes standard mini automotive ATC fuses
to select between series or parallel voice-coil operation (DVC only). The
fuses also provide voice-coil protection under transient conditions such
as accidental momentary overdrive. The fuses will not protect against
voice-coil failure resulting from long term high power abuse.
