The 300W Crown Audio CDi 4|300 4-Channel DriveCore Series Power Amplifier with BLU Link utilizes technology derived from the flagship Crown DriveCore Install series amplifiers, providing an impressive mix of high-performance, rich feature set, and competitive cost. The CDi DriveCore 4|300 offers streamlined functionality for most small- to medium-sized installation such as restaurants, retail stores, and more.

The DriveCore integrated circuit eliminates hundreds of components within the amplifier, reducing the variability of component values and increasing reliability, resulting in remarkable audio fidelity from an efficient design. The 4-channel amplifier is simple to use and includes a network control & monitoring, an advanced DSP circuit, and an easy-to-use, front-panel interface. The amplifier is equipped with two BLU Link RJ45 connectors, which can receive and send 256 fault-tolerant audio channels.

The amplifier is capable of driving up to 100Vrms speaker loads without requiring a transformer and comes pre-loaded with JBL speaker tunings to help make installations quicker and easier. The CDi 4|300 features an Ethernet port for using HARMAN's HiQnet Audio Architect software for configuration and operation over a standard TCP/IQ network. The rear panel includes terminal block inputs and barrier strip outputs.

Related Questions and Answers

Q: 1. How does this compare to the xls1002?

A: The XLS 1002 provides built in DSP, specifically a band pass filter per channel, an integrated crossover system, and limiters. This amp does not.

Q: 2. Would this be a suitable amp to power a subwoofer in a small home theater setup?

A: The Crown Audio XLi 1500 Stereo Power Amplifier could potentially be used in a home theater setup, as it has both SpeakOn and RCA power outputs. However, before choosing a power amplifier it is vital to check the wattage required by the speakers you want to power.

Q: 3. 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: 4. 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: 5. Where is the country of origin for this product?

A: The country of origin is Mexico.

Q: 6. 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: 7. If purchased this amp will be mounted in a television station Production Control Room. How loud is the "forced air cooling fan?

A: Crown Audio has not provided an ambient noise spec for the XLi 800 Amplifier, but with proper ventilation the variable-speed cooling fan can be kept below maximum power, thereby reducing ambient noise levels.

Q: 8. 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: 9. Can it be used for Bass amplification

A: Yes it can most definitely be used for bass amplification

Q: 10. Is this Rms power or max power?

A: The wattage figures given for the Crown Audio XTi 4002 Power Amplifier are peak power levels, not RMS.
