How to replace fuse on crown XTi 2000 - Crown XTi 2000 2-Channel Amplifier

Send a signal from the mixer to the amp directly, seems as if you have a distorted signal from your crossover

hope so.
have a good day

The fuses are on the inside

A loose wire or bad solder connection.

Pressing & holding the prev/up & next/down buttons at the same time will toggle the lock on or off.

common problem with xti series... all the amp needs is a soft ware update contact crown and they can sort it for you... you dont have to send the amp back to them. it was a verry common fault with all the early xti amps..

From your description, I would suspect some poor solder connections inside. If you know how to work on these, check for bad connections near the voltage regulators. That is the mode common area.

These are available for purchase from Crown. Generally they are not available on the web. Is there a specific problem that you are having?

It sounds more like you are overdriving the speakers not clipping the amp. If the output rating for the amp is 1000W into 4 ohms, this is approximately 500W into an 8 ohm load. Your speakers are rated for 400W. If you are running the amp at full output, that is too much power for the speakers and either the speakers are warming up too much and failing or are being extruded too far and failing. Your best bet is to better match the amp/speaker setup. Crown amps have built in clipping indicators and I believe that the xti series also has a compression circuit that would prevent distortion on the output side.

To confirm my suspicions, in what manner are the speakers failing? Are they completely open or do they sound distorted?

Thanks,

This is most likely to be a heat issue where the amps overheat and shut themselves off then cool down and turn back on. Please check that the amps have proper ventilation and that any air ducts are clean.
