I'm trying to program a dbx 4bx into a 15-1994. I've found the advance code (amp 0295) but can't make anything work\. ideas?

It looks like this remote only has a few buttons (judging by the fact that there are only 11 buttons listed here) so the easiest option is for you to just learn them.

If you are already using alot of your learning memory for other things, maybe those things could be re-programmed using advanced codes?

Otherwise, you would need JP1 to add this code to your remote.

UEIC claims that amp_0295 will work for this device; however, they screwed up. The efc's are correct, but they got the protocol details all wrong. Bottom line is you can't use _0295 with any protocol native to the 1994, or any other ueic remote (or any "universal" out of the box).Just to save you wasted time, you won't find the device in any pronto or LIRC files. You might check with "deleted" (I didn't have permission to make any referrals to him) who usually sells these quite often on ebay, he has a source for a universal remote that will work the 4BX. I've seen a few loose oem's go on ebay for 70+. Really suck that so many of these pass thru ebay with the remotes lost/broken, etc.

Jim,
Weren't you able to program the DBX using JP1?

Since you asked, Yes. Fact is, I'm the one that supplied "deleted" and some others with remotes and manuals for any dbx items they may have. Like you, I had a "sideline" specializing in dbx products instead of ueic remotes. I couldn't mention it before since he didn't ask for a source for remotes, programming etc. as I don't condone spamming. All my "business" was strictly from referals from happy former customers.

Since he was trying to use ueic's screwed up code I assumed he didn't have a remote, or as you suggested with just 11 buttons, he would have learned them first, instead of posting a post here. I wuld program his remote if he doesn't want to mess with JP-1 for just one device. I charge 10.00 plus shipping (2.00, 1st class). (offer retracted)

With all the remoteless dbx 4BX's I've seen go thru ebay, it's a good guess he doesn't have a remote. The remoteless auctions is about 80%. As far as dbx and ueic goes, only the DX-5 cd player is supported. You can find a LIRC file for it, but no CCF.

ONE of the details ueic screwed up with the protocol is frequency. They used 38K when the device uses 71K. AMP_0295, as the poster found out is worthless, and while you can get an upgrade from ueic, it isn't gonna work. Of course calling them, or RS they'll tell you to use _0295, but I suspect when the moron at ueic made the code, he forgot to note the protocol details or someone transposed the list wrong and got the setup codes and protocols for two devices swapped.

Since you asked, Yes. I have programming for
ALL the remote operated dbx devices.

IIRC, that was provided to you by John Fine, and you might have the courtesy to acknowledge his contribution.

I've been wondering where Jim got a protocol upgrade for a 71Khz protocol. I have no memory of providing any 71Khz protocol nor anything for DBX. But Jon still might be right. I usually forget such things after doing them.

Jim, could you upload your DBX upgrades to the Yahoo file section please.

To set the record straight:

John did provide a protocol upgrade for a DIFFERENT dbx unit, but it required a good bit of tweaking to make it match the original signal, repeat rates, etc, AND make it "learnable".

The 4BX required a totally different protocol, as noted with the mention concerning the 71K. I think it was Jon that provided the start for this protocol (not John).

At one time John proposed calling his protocol "dbx", but as you can see, there is really at least 2 "seperate" dbx protocols, and his "start" had some minor flaws which he recognized trying to learn signals to another JP-1 learning remote. THAT signal is unlearnable as well from the oem, and is for a preamp. I had to learn to another learning remote, then learn that signal to a ueic remote or it would still be "uncracked". The first remote would at least learn the signals but using the learned signals was a nightmare. Depending upon how it was learned, volume adjustments, for example, would either make HUGE jumps, or so itty-bitty that they were almost undiscernable. The 4BX is a dynamic range enhancer, not a preamp.

The other dbx units all use yet other protocols, the details of which I worked out on my own. Only the DX-5 cd player will work with a ueic provided protocol/setup code, and the only unit I've located on an exhaustive net search.

I've invested a huge amount of time and effort to working out all the details for all the dbx remote operated units, including buying a 1200.00 unit (which I don't use) just to get the unit and it's oem remote to know how it works, and the details needed to make a ueic remote operate similarly. I've also bought an additional unit just to get a remote because the first didn't have one. Same goes for user manuals. I've got almost 100 different user manuals each different because units saw so many revisions. IE, I have 4 different 14/10 EQ manuals (these sell for 455-1000). 4 or 5 different 3BX-DS dynamic range enhancer manuals (these sell 380-550). The 4BX has 1 manual and sells 175-615, generally depending on whether the unit includes the manual and remote, boxes, rack-mouint ears, etc.

Most people don't recognize the dbx name, since they have been strictly a pro recording speialist company for the last 13 years, and are no longer in the home stereo market. However, MOST stereo TV's use dbx technology now-a-days. When they were in the Home stero market, it was all TOP-end equipment, and rivals or beats what's currently available. It's up there with Carver in the audiophile market. Devices are still quite active at places like ebay, audiogon, and other net sites devoted to the audiophile market. I'd guess I have some 200+ dbx units myself.

There, concerning the 4BX, acknowledgement given and noted, not that it was intentional in the second post; I guess I focused too much on Rob's inquiry and made the reply too narrow. My apologies to Jon.

Jim

Thanks for all your help. It's good to know I'm not crazy or stupid, the codes don't work. I'm going to try and program with a jp1 on a 1994 and ofa 9660. I've never done this before, so wish me luck. I may have to ask for additional help. Jim if I can't figure it out, I'll send the remote to you for programming.
As a matter of history I bought the 4bx new 20? years ago and the remote was lost during moving. It is unlike anything avaialbe now. It works and works well adding nothing but dynamic range and attack.

One question is there any way to get around having to own excell for the spread sheets? I own lotus 1-2-3 ver 9.

If Jim loads his upgrade files into the Yahoo "Audio" folder, you shouldn't have too many problems getting it programmed.

Fact is I can't. All my files were wiped when I suffered a HDD crash shortly after working out all the details. I had made my offer intending on obtaining the unit and oem remote at considerable expense to myself (and wife) just to help this guy out. However, due to various postings, there's no way I can recoup those expenses, and can't expect my wife to subsidize. That doesn't include the involvement and expense to other people I have obligations and responsibilities to, nor dragging them into the whole mess. At least 5 other people I personally have relationships with would suffer some losses, and it's not my place to impose of them in that way. I've explained to Rob, personally, and would expect that he keep that in confidence.

Jim did email me and I understand.

However, all might not be lost. There were several other people involved in figuring out the DBX stuff, so it's quite possible that some of them still have copies of some of the files. So why don't we all see what DBX stuff we have on our HDDs and re-group.

Anything new on the dbx 4bx front? I have my 15-1994 remote but am still waiting for my jp-1 cable from filebug (paid for no delivery, should have built it myself!) You mention other remotes that work with the 4bx, which ones?

Would like to get this unit working as without it I have no volume remote on my theater system.

Help
