1 Welcome
Crown ® System Solution Topol-
ogy (SST) modules bring you
superior control and fl exibility with
the convenience and cost savings
of plug-in processing. SSTs plug
quickly and easily into the back of
your amp.
When you use a Crown SST module
to split the power drive to the loud-
speaker components, you gain a wide
range of advantages, including:
1. Increased gain because the inser-
tion loss of passive crossover
networks is eliminated.
2. Consistent power bandwidth:
power bandwidth is changed
in multi-way passive systems if
transducers change impedance
or vaporize (blow up).
3. Levels can be matched more
accurately to the components.
4. Quicker troubleshooting.
5. Improved dynamic range.
6. Better protection of components
due to steep 24-dB/octave fi lters.
With hard-wired precision compo-
nents, SST modules deliver consis-
tent bandwidth control, more accurate
level matching, and increased gain
(with none of the insertion loss found
with passive crossover networks).
Compact and versatile, Crown SST
modules continue the Crown tradition
for fast setup, great-sounding output
and exceptional value.
1.1 Wiring
All SST modules feature balanced
inputs. Some models also feature
balanced outputs for routing signals
to other amplifi ers in biamped and
triamped systems.
Following are the standard wiring
conventions to follow when wiring
balanced connections to SST mod-
ules:
XLR (AES Standard)
Pin 1:
Pin 2: +
Pin 3: –

Barrier Block and Terminal Block con-
nections should be wired as marked
on the SST front panel.
