Crown XLS 2000

Recommended Posts

I have bought Crown XLS 2000 and too disappointed!

Because it's real power is around 300W per channel (with 4 Oms per ch.)

I've measured it with oscillograph and tester.

Why the info on the official site differs from real?

Minimum Guaranteed Power

XLS 2000

Stereo, 4 ohms (per ch.)

650W

http://www.crownaudio.com/amp_htm/xls_drivecore.

Please explain my amp is broken or the information on the site is absolutely incorrect?

Many thanks for help!

Are you using a sine wave input? What voltage and frequency is the input signal, and what input jack are you using? Are you using a power resistor? How are you measuring power?

We get challenged on power specs every now and then, and every time I do a quick check in our lab here, our specs are validated.

Are you using a sine wave input?

Yes, we are using a sine wave input

What voltage and frequency is the input signal, and what input jack are you using?

U=0.7V F=1Khz

Are you using a power resistor?

Yes, we are using a power resistor

How are you measuring power?

P=(U*U)/R

sticker on back side of amp is 350W, what is it mean? http://xmages.net/i/3139369

Thx.

In order to get full output first you need to show 1.4 volts to the input not .7 volts and this is a minimum (gain knob at 0) cheer.

HaHaHa

One have to measure correctly before make any statements :D

I believe that the sticker (350Watts) is how much it will consume from the AC outlet from the wall.

One question is how big is the power resistor?

Thanks
