5 Advanced Features & Options

BCA
®
(Balanced Current Amplifier) is Crown’s patented, cut-
ting-edge technology that gets more power out of an amplifier
with less waste than was ever before possible. A completely
new adaptation of standard amplifier design, Crown’s BCA
“switching” amplifier design provides for high output, excep-
tional reliability and nearly twice the efficiency of typical ampli-
fier designs.
While switching designs have been used successfully in other
applications, these designs were never before suitable for use
in precision, high-power audio amplifier applications. Crown’s
BCA technology changes that, with a totally new paradigm for
amplifier design that represents the future of professional am-
plifiers.
With their superior efficiency, BCA amplifiers can help to keep
your power bills down, while still putting out amazing, bass-
thumping lows and crystal clear highs. And your Crown BCA
amp is tough—easily handling very low (and highly reactive)
load impedances, even under extreme conditions. In fact,
Crown BCA amps have far out-performed competitive amplifi-
ers in tests where the amplifier was run as much as 12-dB into
clip for extended periods of time.
High efficiency, tough robust design and great Crown sound
make Crown BCA amplifiers the clear choice for professional
musicians everywhere.
Switching Power Supply with PFC
Crown’s new Switching Power Supply with PFC provides a
range of benefits over both non-switching and conventional
switching power-supply designs.

housing, making sure that the large notch on the outer
edge of the chuck lines up with the large groove on the
inside of the connector housing. The chuck should slide

Slide the bushing along the cable and screw onto the end
of the connector combination as shown in Figure 4.11.
Note that the bushing features a special locking con-
struction which will prevent disassembly of the
NL4FC connector once this cap is tightened into
place. Before tightening, you may want to test the con-
nector in a live system to make sure it has been as-
sembled properly.
