SST-SBSC (Summed Bass Stereo Crossover) Module

Crown’s advanced SST-SBSC module offers ten user-speci-
fied crossover frequencies, CD horn EQ and summed sub-
bass output for driving subs (see Figure 5.3 for block diagram).
The SST-SBSC offers the following features:

•

Stereo biamp.

•

12-, 18- and 24-dB (Linkwitz-Riley) / octave filters.

•

CD horn equalization.

•

Mono summing of sub-bass output for driving subs.

Crown plans to release additional accessory plug-in modules
offering a range of advanced features and capabilities. Watch
for new releases.

Fault Monitoring

The Fault (RJ11) jack, which looks like a telephone plug, is
located on the back of your CE 4000 amplifier. It gives you an
easy way to remotely monitor the amplifier’s fault status. To set
up a circuit that will cause an LED to light whenever a fault
status occurs, you can simply use the suggested circuit shown
in Figure 5.4.

When using this circuit, the LED will glow whenever the ampli-
fier is in one of four states: a channel’s heatsink has reached its
temperature limit, the transformer has reached its temperature
limit, the amplifier has just been turned on and is in its turn-on-
delay mode, or the amplifier is turned off.
