CE 4000 Power Amplifier

PFC, however, compensates for phase differ- ences in the power supply, allowing more true power to be transferred to the amplifi er. The result is more power with less waste than any other conventional switching or non-switching design.

As an added benefi t, PFC also allows the amp to be connected to any common AC line volt- age, without converting the power supply. This means that whether you’re running one or two amps on a household circuit or several amps on a power distro, your CE 4000 amplifi ier is ready—right out of the box.

	5.3 Other Features
	5.3.1 Low Pass Filters
	For each channel, a back-panel, three-position
	switch provides optional settings of Flat (Left),
	80 Hz (center) and 100 Hz (right) with an
	18-dB per octave rolloff (see Figure 5.4). The
	80- and 100-Hz settings may be selected when
	the amplifi er is being used to drive a bass
Figure 5.4 Low-	program. The FLAT setting provides bypass
Pass Filter	of the low-pass fi lters, for use either when a
Switch	crossover is provided elsewhere in the system,
	or when the signal is full-range.

5.3.2 Neutrik Speakon Wiring

The Neutrik Speakon NL4 connector is a four- pole type, which allows either one or two sets of speakers to be wired to one connector.

5.4 Options

5.4.1 SST Modules

Crown’s optional SST (System Solution Topol- ogies) modules were specially designed to improve the fi delity and versatility of your audio system. They feature a variety of pro- fessional signal routing and fi ltering capabili- ties. Your amplifi er may have come with an SST module already factory-installed, or your choice of SST modules can be easily added to the amplifi er by any authorized Crown Service Center. For information on available SST modules, visit the Crown website at www.crownaudio.com.

5.4.2 Output Connectors

For added system fl exibility, Crown offers optional output connector confi gurations for your amplifi er. If you prefer, you can choose to have dual Neutrik Speakon® output connec- tors (model CE4E) or 5-way binding post plus barrier strip (model CE4C) connectors installed in your amplifi er in place of the standard Neu- trik Speakon® plus 5-way binding post outputs (model CE4D) at time of ordering. For informa- tion on adding optional output connector mod- ules to an existing CE 4000 amplifi er, please contact Crown Technical Support (see Section 8 for contact information).

5.4.3 Handle Kit

Handles complement your amplifi er’s appear- ance, aid in transportation, and the placement in or removal from racks. They are available from Crown’s Sales Department.
