CE 4000 The amp with an Attitude! 2 Installation Follow these instructions for a detailed explanation of CE 4000 installation procedures and options. If you just want to get up and running as quickly as possible, see the Quick Start section on page 6. 2.1—Begin with the amplifier turned off and disconnected from the power receptacle. The CE4000 power switch is located on the left side of the front panel; it is off (“O”) when depressed on the left.
CE 4000 The amp with an Attitude! Fig. 2.3 Typical Input Wiring CE 4000 The amp with an Attitude! Output Wiring Tips 1. This amp offers Neutrik Speakon® connectors to minimize wiring mistakes.* We also encourage you to choose carefully when selecting speaker enclosure connectors. 2. To prevent possible short circuits, wrap or otherwise insulate exposed loudspeaker cable connectors. 3.
CE 4000 The amp with an Attitude! 2.6—Check to make sure that adequate ventilation has been provided. Even though this amplifier has some of the most efficient heat sinks in the marketplace, it must be able to breathe. So make sure that the front vents are never blocked and that the exhaust fan (out the back) notblocked or covered by cables. An amplifier running at high sound pressure levels into low-impedance loads will typically put out lots of hot air, so make sure it can go somewhere.

CE 4000 The amp with an Attitude! CE 4000 The amp with an Attitude! 3 Operation Figure 3.1 Front Panel Indicators & Controls Your CE 4000 amp is really very easy to operate, once it has been properly configured. If your amplifier has not yet been set up or configured, please refer to the installation instructions found in Section 2 of this manual, or consult with your system installer. Follow these steps when first turning on your amplifier: 1 Turn down the level of your audio source.

If amplifier output wires develop a short-circuit. 5. Should the amplifier output stage become non-operational. The fault status of the amplifier can also be monitored remotely by attaching a signalling device to the Fault jack located on the amplifier back-panel.
CE 4000 The amp with an Attitude! CE 4000 The amp with an Attitude! Mode Switch: This two-position switch, located on the back panel, allows the selection of either Stereo or Bridge-Mono mode of operation. 4 Crown Pro Information Guides Stereo mode provides identical power output to each of the two amplifier output channels. Bridge-Mono Mode combines the two amplifier output channels into a single mono channel with twice the voltage of a single stereo channel.
CE 4000 The amp with an Attitude! CE 4000 The amp with an Attitude! Fig. 4.3 Balanced Input Wiring Hum and Buzz Tips 1. It is imperative that all of your electrical equipment share the same power ground reference. 2. Unless you are interfacing to a microphone, the shield of the cable should only be connected at one end. (See Fig.4.3) 3. Do not pass signal ground between electrical components in a grounded source system. 4.

Slide the chuck (D) along the cable and insert into the 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 easily into the insert/housing combination until only approximately 3/8-inch (9.
CE 4000 The amp with an Attitude! Typical non-switching power supplies require large, heavy transformers in order to produce the required power at the output stage. These transformers must be large to absorb the substantial waste that occurs when operating at 50 to 60 Hz (standard AC supplied by the power company). By contrast, switching power supplies can operate with a much smaller (and lighter) transformer because they first convert the AC up to a much higher frequency, thereby reducing waste.

CE 4000 The amp with an Attitude! Principles of Operation mance. Warning: Details of closed loop amplifier design are beyond the scope of this description and if discussed, would surely put most readers to sleep! Audio Signal Path For the sake of simplicity, only channel one of the audio signal path is described. Signal is presented to the CE 4000 through one of three connectors when using the standard input module. Each channel is outfitted with a balanced XLR / phone jack, and a barrier strip.
CE 4000 The amp with an Attitude! used for low to moderate duty work. If the amplifier is delivering large amounts of power into low impedance loads, the heatsinks or transformer may heat up enough to increase the speed of the fan to medium and possibly to high speed. If the temperature continues to increase, the TLC circuit uses the compressor to reduce the gain of the input stage and thus reduce the power dissipated by the amplifier.
CE 4000 The amp with an Attitude! Power LED is driven from the low-voltage supply. Power Supply Operation AC power enters the amplifier through a power cord equipped with an IEC (unplugable) connector. It then is passed through the EMI filter. Circuits that use switching technology will normally send a small amount of high-frequency noise back down the power cord and into the power distribution system. This noise must be removed in order to sell the unit in certain parts of the world.
