Older Rane processors and the power supply

what's up with thinking the supplies in those units are separate or plug in units? are you talking about the wall wart transformers?

both units use the ubiquitous 7815 and 7915 regulators and other than caps and diodes are pretty standard on board supplies... would be a easy rebuild...and thanks to Maaco you now have a link for the schematics!

Just checked the manual and a few posts: lots of bad info/data above which will *destroy* any Rane processor subject to them.

They need 9+9V **AC** or 18V center tapped **AC** which is the same.

NOT DC, no 18+18V AC or DC, etc.

You can make a power supply or find somebody who does (google is your friend) but it must meet Rane specs and use the proper connector, wired the proper way.

https://www.rane.com/pdf/old/rs1dat.pdf

Parameter Specifications Limit Units Conditions/Comments
Output Voltage 18 CT (center-tap: 9+9) VAC Rated load, 120 VAC line
Maximum Output Current 750 mA

Of course you can use a higher current rated transformer, such as 1A or even 2A ; your processor will take what it needs.
 
always liked the Rane stuff but did have grief securing those transformers in the racks they lived in without the box shifting and pulling on either the power connection or other patch cables or simply getting in the way.
i saw one tech who was using 8 AC23's to run a large bi-amp monitor rig, he spec'ed a transformer with enough current to supply all the units via a fan tail buss that eliminated all the redundant supplies.
 
OK, Thanks every one, I thought they would have regulation inside which means I can use a 9-0-9 center tap transformer and the RJ12 plug (which should arrive today).

I found a 3 amp CT transformer, which will power an AC22 I use for my subs/main crossover and I use 2 DC24's, one is for the kick and snare and the other is used to protect the mains and subs from any stupid acts on stage.

Those wall warts are a PITA but I found velcro holds them really well.

Rane use to sell a unit that would power 8, but those go for more then I want to spend on Ebay. I always used lots of velcro to hold the wallwarts in place in my equipment rack. The cords are stupid long though, I zip tied them but it never looks neat enough for me.
Every one I have bought has broken screw downs and usually missing the lock tab on the RJ12 connector. I ordered 100 of those since it was 50 cents more then 50 haha.

Even though DSP and Digital is replacing these items I still prefer hardware to software.
 
We have no clue about what those Rane processors need, looks you have no clue either.

At least post the respective user manuals, to check what they ask for, and much better if you post the schematics.

Do your homework and will get proper answers.

Sorry, I'll put a drawer up on my web server so I can post pictures here.
won't happen again
thanks

a lot of products while being designed for use in north america is made overseas in a country with a different voltage standard and if your planning to export the product it's an easy change to make and avoids the end user or the importer having to outsource the work to retrofit the equipment or rewire the transformer (not all devices come with those handy line voltage selectors)and there is a different set of regulations with respect to voltage and safety standards when it becomes classified as a "low voltage" rather then "line voltage" device.
Maaco i would not be surprised to find out that because of import, safety, or differences in electrical code regulations, product in your region must be "fully contained in a single chassis".

i once had to leave a rack of Dbx 900 series comps and a rack of Rebis gear in a security locker at the airport in Johannesburg because they where considered a "non enclosed device".
