Designed for musicians, DJs, entertainers, houses of worship, discos, and other venues, the Crown XLi 3500 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 1350W per channel at 4 ohms, 1000W per channel at 8 ohms, and 2700W at 8 ohms in bridged-mono mode..

• Stereo/parallel/bridge-mono mode
• User-selectable input sensitivity: 0.775V and 1.4V
• Efficient forced-air cooling prevents excessive thermal buildup
• Electronically balanced XLR inputs and RCA inputs; binding post and speakON outputs
• Two level controls, power switch, power LED, and six LEDs, which indicate signal presence, clip, and fault for each channel
• Protection against shorts, no-load, on/off thumps and radio-frequency interference

Related Questions and Answers

Q: 1. How does the remote trigger work? Is it a separate piece of hardware? Is it signal sensing?

A: Is the xls 2502 stronger than an xli 3500 or vice versa?

Q: 2. 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: 3. 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: 4. 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: 5. Can I use 2 of these for my Atmos speakers 4 speakers?

A: So long as your Atmos speakers were spec'd for a program power rating of 200 watts at 8 ohms per speaker, then yes this amp could work. To maintain 4 channel separation, you would want to run 2 amps for 4 speakers.

Q: 6. 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: 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. 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: 9. 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.

Q: 10. Can this handle a 2 Ohm load?

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