Designed for musicians, DJs, entertainers, houses of worship, discos, and other venues, the Crown XLi 2500 Stereo Power Amplifier feature both RCA and XLR inputs as well as speakON and binding post outputs. The amplifier includes a user-selectable input sensitivity of 0.755V or 1.4V, stereo/parallel-bridge-mono modes, power/fault/signal presence/clip LED indicators, forced-air cooling, and protection against shorts, no-load, on/off thumps, and interference from radio frequencies in the environment.

Drawing from over six decades of experience in building amplifiers, the unit is capable of delivering 750W per channel at 4 ohms, 500W per channel at 8 ohms, and 1500W at 8 ohms in bridged-mono mode..

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. Will this work in Australia which is 240 volts?

A: The Crown Audio XLi 3500 Stereo Power Amplifier that we sell is rated at 120V AC, 60 Hz for use in North America. However, you can use a step-down transformer to enable powering at 240V.

Q: 3. How much rack space does this amp take up?

A: Actually it is a 2RU form factor. About 4 inches is correct. Each RU is about 1 7/8 inches.

Q: 4. Is that 775watts at hz or khz?

A: Neither. The power rating for an amplifier is not related to the frequency response. The 775 Watt power rating for the Crown XLS 2502 Stereo Power Amplifier is for each channel when the amp is operating at 4 Ohms. This means the amp will deliver 775 Watts to each channel to drive a 4 Ohm speaker. The maximum power the amp can output will vary depending on the impedance of the speakers that are connected. With an 8 Ohm speaker the amp delivers 440 Watts per channel and with a 2 Ohm speaker the amp delivers 1200 Watts per channel. When speakers with lower impedance ratings are use the amp will deliver higher amounts of power.

Q: 5. 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: 6. 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: 7. 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: 8. 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: 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. 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
