Author Topic: Need info on Dolby Cat 150 Card Sam Hunter Jedi Master Film Handler Posts: 779 From: West Monroe, LA, USA Registered: Jan 2002 posted 02-10-2003 10:11 PM                     My CP50 has what appears to be a newer version Cat 150 card which doesn't match the schematic found in the manuals section of this forum. What I have is a CAT 150F Rev 5 module. Could somebody tell me what this card can do and send me info on it? I am unable to get audio out of my processor unless I press the OPT Failure switch. I have traced the audio signal to pin 10 of the CAT150F card but there is no output on pin 4 of the card. All operating voltages are present and the mono/stereo select line on pin 14 is high. I feel like I have a defective card but maybe there is something else I need to check. The L, C, R, LED's are solid on with the S LED not lit. Thanks!

There are a couple of voltage regulators on there that run quite hot and one may have failed. You could remove the 150 card and use either the LT or RT input signal to the 150 to jump over to the L,C,R,S output pins and see if the CP50 passes audio ok. If it does then do an RXO for the 150F. Donno what they charge for that, but it may be as much as the 50 cost you....The 50 is still well worth fixing though.

The Prologic IC doesn't feel warm at all.  |  IP: Logged Sam Hunter Jedi Master Film Handler Posts: 779 From: West Monroe, LA, USA Registered: Jan 2002 posted 02-11-2003 12:51 PM                     OAO [ 02-12-2003, 01:29 PM: Message edited by: Sam Hunter ]  |  IP: Logged Mark Hathaway Film Handler Posts: 31 From: Australia Registered: Nov 2001 posted 02-12-2003 07:30 PM                     Sam, while you have your cp50 apart, check for excess ripple from the power supply, its a non regulated pc with just a few caps and diodes, and the caps are probably quite dry by now. I've seen 1v p-p ripple on the +24vdc rail (I think it was +24vdc) cause the cat150 (early version with sanyo decoder ic) to make strange noises when the surround gate opens and closes.

I sent the card back to the company I bought it from and they said they didn't have another card to replace it with and that he would look around for one. In the meantime I have another source who has a working unit for 100 bucks more that what this one cost plus shipping. I think I might see if they would take this unit back and refund the price and buy the other unit. What do you do in this kind of situation? Wait and see I guess.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 02-12-2003 09:43 PM                     never had a dead cat 150F yet to deal with is a 110L or 160 installed  |  IP: Logged Steve Kraus Film God Posts: 4094 From: Chicago, IL, USA Registered: May 2000 posted 02-13-2003 12:42 AM                    Sam, just jump Lt to L and Rt to R and sit in the middle!  |  IP: Logged Sam Hunter Jedi Master Film Handler Posts: 779 From: West Monroe, LA, USA Registered: Jan 2002 posted 02-13-2003 08:17 PM                     Or use headphones Hey Gordon, I have the 110L bypass card in my CP. Will update to the LFE card later, money getting low. Where would I send this card in to be repaired and what would I be expecting price wise?

Surely somewhere in this country there ought to be a CAT150 card someone could let go of.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 02-16-2003 01:03 PM                     Since they don't often fail most people don't keep a spare lieing on the shelf contact your local dealer and Dolby will do a repair/ exchange on the 150F some of the older ones the chips just aren't made Basically the dealer will ship you a card and you pay for it and then get a credit on the old one less the repair cost  |  IP: Logged Sam Hunter Jedi Master Film Handler Posts: 779 From: West Monroe, LA, USA Registered: Jan 2002 posted 03-01-2003 04:57 PM                     Well, the saga continues. I sent my CAT150F off to be replaced and I recieved a CAT116A card instead. I didn't think much about it at the time as not knowing a whole lot about this thing I figured it was an early version CAT150. Anyway, installed it and and noticed that my right/left and surround works ok but no Center. Got to checking and found out that the CAT116 does not perform the same function as the Cat150 The book says that the Cat116 is to be used in conjuntion with a Cat110 module. Is the Cat110 the same as a Cat110L? Actually by rereading the manual I find that the CAT116A only decodes the Surround. Here is my card compliment, can somebody please explain to me whats missing or whatever? 2 Cat108 2 Cat22 1 Cat109 1 Cat110L 1 Cat116A (Was Cat150F) 3 Cat64 1 Cat117 1 Cat112 1 Cat114 Thanks! It just dawned on me what the difference is between the cat110 and the Cat110L. The Cat110L bypasses the Cat110/160 and also by turning it around and and plugging it into Slot 7 bypasses the decoder card. Anyway it looks like I have 1/4 of a working system  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 03-01-2003 05:21 PM                     the 110/116 is the original low seperation chipset from sansui and is terrible Contact a reputable Dolby dealer and do a repair exchange on the 150F as it will be cheaper in the long run with far less frustration as well  |  IP: Logged
