Paradigm 690 Clipping?

post #1 of 5
Thread Starter 
I've been having a small issue with my Paradigm Studio 690 center channel. In a few specific scenes in movies, it seems center channel is clipping. I tried it with a yamaha 1800 and also with an arcam avr600 and the same thing. When I turned the volume way down, the clipping went away.

Now this is probably slightly loud, but still seems about the level I would watch an action movie. Not earbleeding levels by any means.

Has anyone else seen this with a 690? Do I need an external 1 channel amp? The center is a pretty powerful speaker, so I would think it wouldn't have this issue.

Looked all over the internet and couldn't find any help....

What do you mean by clipping? Do you mean the sound is breaking up? Or is the sound becoming harsh and unlistenable? If the sound is breaking up the speaker may be damaged or you may have a bad connection in the speaker wire, or the bare wires may be touching somewhere. Otherwise, "clipping" is something normally associated with power amplifiers and it is possible your amp or receiver center channel is clipping if overdriven, especially if the speaker is rated at 4 ohms. That would cause harshness and unpleasant sounds, and often will cause the receiver or amp to shut down, else it damages your speakers (which may have already happened). Can we assume you are not running the center speaker full range? If not that should be done and could solve the problem. Otherwise, check those speaker wires/connections. If you suspect the receiver amps are clipping with that speaker then consider a separate power amplifier, or a new center speaker that is easier to drive (8 ohms, 95 dB or higher sensitive should do).

Maybe I don't know what clipping is. Basically, there's distortion in the dialogue....that's what I was calling clipping.

How do I run the speaker full range? I guess I'm not familiar with that....

Thanks for writing back and I'll check the connections as well.

Clipping is a pop or any distortion usually caused by either not enough power to the speaker and its driven to that stage or it could be a damaged tweeter or crossover. I've had to take a Paradigm Ref 20 back to where it bought because a tweeter failed after only about 6 months. By full range he means are you running as a large in the 1800 settings. If you are try setting it to small along with all others and just let the sub handle the bass. If you don't have a sub, try setting L/R fronts to large and the center to small and see if that helps. The 1800 should handle those speakers easily. Did you run YPAO when setting this receiver up? If after trying all this it still clips or sounds lousy your speaker may already be bad.

Thanks guys. I ran the Room EQ before, but didn't activate it under the input. After doing so, the distortion on the center channel went away.

Thanks again.
