The DCi 21250 Two-Channel Analog Power Amplifier from Crown Audio is a two-channel high-performance power amplifier from the DriveCore Install Analog Series which delivers 1250W of power at 4 ohms. It is recommended for installed sound, cinema, and recording broadcast.

Two channels in one 2RU box allow smaller infrastructure rooms that can reduce operational costs while giving you installation flexibility.

The DCi 21250 helps economize by using smaller gauge wiring to drive the speakers using either 70 or 100 Vrms. DCi produces audio quality efficiently without a step-up transformer at the output.

Drive either one or two speakers in low-Z mode, or multiple speakers in high-Z mode (70 or 100 Vrms). DCi powers all loads on a channel-by-channel basis.

DCi Series' channels are bridgeable, even in 100Vrms mode, which allows adaptability for higher power applications such as subwoofers.

Save power by integrating the amplifier into a control system so you can turn it on and off.

Efficient internal cooling fans provide airflow to the heat-generating parts. Incorporating the fans into the amplifier brick design maximizes cooling while minimizing wasted energy and noise.

The power supply is designed to keep down the amount of power being dissipated and the amount of heat building up in your racks.

Related Questions and Answers

Q: 1. Can this handle a 2 Ohm load?

A: No it is not designed to handle anything below 4 Ohms.

Q: 2. Do these get alot heat?

A: It will get warm to touch which is normal: Internal heat sinks with forced air. Fan cooled, speed regulated, thermal protection

Q: 3. Is there an aux cord? or would I need the usb cord and then an adapter to the phone?

A: The CDi2000 is designed for commercial installations. The inputs on this power amp are 3pin phoenix connectors. If you are looking to connect audio devices to the amplifier, it is recommended to do so with a mixer which can be wired with adapters to the phoenix connector inputs of the amplifier.

Q: 4. Does it have a fan? How noisy is it?

A: Yes, there are internal cooling fans included with the XLi 1500 that help to prevent the amp from overheating. The fans are fairly quiet, not noisy.

Q: 5. What is the out power sourse for this 4002, is it transister or fet?

A: The output power source of the Crown Audio XTi 4002 is transistor.

Q: 6. Of any class of this ( Crown xti 1002)Thank

A: The only reference to class : XTi2 Series amplifiers require Class 2 output wiring

Q: 7. If there is a power outage do you have to press that switch to power the amp back on or does it stay depressed?

A: I am sorry but there are no details posted in the product information or specifications regarding whether the power switch would need to be pressed again after a power outage. The Crown Audio XLi 1500 Stereo Power Amplifier does have a circuit breaker with a reset switch on the back panel to protect the amp from a surge. The circuit breaker may activate if there is a power outage and then you would press the reset button and most likely would have to press the power switch again to turn the amp on.

Q: 8. Is the XLi 2500 a push/pull amplifier?

A: Yes. The Crown Audio XLi 2500 Stereo Power Amplifier uses Class AB circuitry, which has a push-pull output stage.

Q: 9. Can I stack one on top of the other without heating problems?

A: It is recommended to leave at least 1u of space between amps to reduce potential overheating issues

Q: 10. WHAT IS THE VOLTAGE OF THE CROWN XLI 2500 POWER AMPLIFIERS? THOMAS BROWN

A: The Crown Audio XLi 2500 Stereo Power Amplifier and the other Crown amps that we sell operate at 120 VAC, 60 Hz.
