The Crown Audio DCi 8|300 8-Channel Amplifier 300Wis an 8-channel amplifier capable of producing 300 watts of output per channel and works with 2, 4, 8, and 16 Ohms or 70 or 100 Vrms. Channels can be bridged for powering higher-power applications such as a subwoofer. The DCi 8|300 also has channel-independent high- or low-impedance output that is selectable from the rear-panel DIP switches. This allows you to integrate the amplifier into a variety of different setups. Each of its 8 channels additionally features independent attenuators with an attenuation range from 0 to -95 dB.

The front panel of the DCi 8|300 provides a series of system indicators, including level and signal, ready, clip, thermal, and fault alerts for quick visual monitoring of the system. The unit can be integrated into a control system for powering on and off as well as engaging its sleep mode for saving energy when not in use. The DCi 8|300 is 2 RU rackmountable and ships an IEC power cord.

Based on Crown's proprietary and patented DriveCore technology, this amplifier features the next generation of PWM technology using Class-D amplifier topologies

Minimum Guaranteed Power Ratings: Delivers at least the rated power in the specifications over a long period of time

Direct Drive "constant voltage" capabilities on a channel-by-channel basis for 70 or 100 Vrms amplification without the use of a step-up frequency limiting transformer for higher audio quality

Powersave: Includes an auto-standby mode where after 30 minutes of no audio input, the amplifier powers down and consumes less than 1W—this feature can be enabled and disabled via the back-panel DIP switches

Advanced PFC universal power supply provides efficiency and is designed to deliver maximum power no matter where the amplifier is located—universal AC input accepts 100 to 240 VAC, 50/60 Hz (±10%)

Aux Port: Provides additional flexibility for amplifiers to be integrated in control systems for remote on/off and amplifier fault monitoring

Cooling System: Focuses airflow on parts that need it most, maximizing efficiency while minimizing heat and noise

DriveCore features five patents that are also included in Crown's flagship I-Tech touring amplifier

Related Questions and Answers

Q: 1. can I use a 2002 and 2502 both bridged without significant problems?

A: The amps can each operate safely in bridged mode as long as you are connecting them to speakers that are compatible with the power and impedance ratings.

Q: 2. I am thinking of running the amps in bridged mode, can put one amp on top of the other without causing heating problems. I don't have a rack.

A: For proper venting, it would be best to leave them side by side if you don't have a rack.

Q: 3. How loud are the fans when playing at high volumes?

A: The fan used is specified at 28.3 db/A. An engineer at Crown did a test and was getting between 71 and 75 dB right at the fan, and about 45-55 dB at 1 meter. The test was done in a lab with multiple amps and DSPs running in the background as well; so the unit alone would be much quieter.

Q: 4. 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: 5. 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: 6. 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: 7. Do you hear the fans when all is quiet?

A: On the XLi series amplifiers the fans do operate when the unit is idle. They may even increase in speed once the unit reaches a specific operating temperature. I generally recommend the amplifiers be housed in a closed rack enclosure to mitigate fan noise if the unit is going to be housed in the listening space.

Q: 8. Harmonic distortion is specified at 0.5%. How much greater or Is this a typo?

A: That is a TYPO. It should read 0.5% (Info from the Crown XLS 1002 Manual).

Q: 9. Does it do summing in bridge mode to thru both channels from satellite unit to subwoofer unit?

A: No. When using the Crown Audio XLS 1002 Stereo Power Amplifier in bridge mode, the power of both amp channels is summed into a single channel, so only one output is available.

Q: 10. Will the amp conserve all configurations if unplugged?

A: The configurations of the Crown Audio XLS 1002 Stereo Power Amplifier are saved when powered off. The configurations are only lost if a factory reset is performed.
