Related Questions and Answers

Q: 1. 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: 2. 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: 3. How loud is this amp, I have 2 18" subwoofers at 4ohms running indoors?

A: This amplifier delivers 775 watts of clean power at 4 ohms. Actual volume, or SPL, will depend largely on the speakers themselves, but that is quite a bit of power being driven to 18" subs in an indoor setting.

Q: 4. I have two 4 ohm subwoofers, can I use a xls 2002 and xls 2502 bridged without a lot problems?

A: Each of these amps will run one 4ohm subwoofer in bridged mode.

Q: 5. 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: 6. what will be the RMS wattage be with 6 ohm speakers, eg, cerwin vega xls 15 ?

A: Crown has not provided wattage ratings for 6 ohms, but they do list ratings for 4 and 8 ohms. We can use the specs listed for peak wattage to calculate RMS wattage at 4 and 8 ohms. 6 ohms is going to be right in the middle so you can get a better idea of how it would perform with your speaker. At 4 ohms, the XLS 2502 is rated at 775W per channel and 2400W bridged for peak power, which works out to approximately 550W per channel and 1700W bridged for RMS power at 4 ohms. At 8 ohms, the XLS 2502 is rated at 440W per channel and 1550W bridged for peak power, which works out to approximately 310W per channel and 1100W bridged for RMS power at 8 ohms.

Q: 7. I saw in pics that it's has some kind of selector For 220v, it's multivoltage?thanks!

A: Unfortunately, the Crown Audio XLS 1002 does not feature a worldwide power supply. They come factory set to work in the region in which they have been sold to; in our case, North America. The marking in the back with the various voltage selections are just an indicator of the options available through crown, but are most definitely marked by region.

Q: 8. is this compatible with two JBL AWC62's as well as two JBL AWC129's?

A: Yes

Q: 9. 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: 10. 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.
