Hi again. Smallish house with a CP45 and CE analog reader, passive crossover speakers (JBL) and USA900 amps. Sound is fuzzy especially on right channel. It is audible on my trailer test reel but I would say not objectionable, but there isn't much except loud sound on the trailers. On X-men Origins the sound is really bad, lots of distortion in the right channel particularly. Most serious with speaking level, explosions etc just sound loud as usual. SO far I've changed a bad amplifier (fan gummed up, thermal cutout every few minutes - but sounds OK), the CP45, and the CE reader unit. The distortion stays with the amplifier channel, ie the speaker itself is OK. Sound is fine in mono ("enhanced mono" using LCR). Sounds better in "A" than SR. I know the CP45 SR is unexcellent, but this is beyond the usual 222 SR/A fuzziness. The only thing I have not changed so far is the CE red LED or power supply. Dolby tone, buzz/LR, and pink noise look and sound OK. NS sounds OK. I changed out the processor thinking the matrix must be going screwy. Today was rather frustrating when the dang thing still sounded bad. The cinema swapped X-men to another house and they say it sounded fine (another CP45) but I wonder about the print anyway. Any ideas before my next visit? I'm kinda low on them now.
