self switching rca Jack

zeropoint0.5 · Post by **zeropoint0.5** » Mon Jun 02, 2014 12:35 pm

In a route 66 i'm busy with, it seems i have a bad self switching rca Jack, the input rca of the rear ( M25 section )

i have a couple of boards i could take a replacement rca jack out, like an M25 board, but i don't know if there was

just one type of rca jacks used in the M series or there is a diff between a "normal" rca jack and self switching types ....

in a outlaw on the M50 section and M44 on the rear input there"s also a " self switching rca jack " ..................

If all the rca inputs of the m series were just one type it would be easy to replace it with another one.......

would love to hear some info on this one........it will save me some time...............

thanks in advance......

Am sure all the M-series amps have the same exact RCA's...as well as the processors that have the same style RCA.

How do you know its bad? Signal doesn't go through? RCA's are loose?

The only place I see those "self switching" RCA's are when the amp board is 4 or more channels (in one board...not special edition two boards in one chassis). Such as 500.4ti or the zx450, where you could run all four channels with one set of RCAs. And even then those have switches to select the input signal on the rears (rear input, front input) so doubt the RCA's are really "self switching" but I could be wrong.

I'm doing a test setup with 2 route 66's, one for the left and one for the right..... all channels brigded......

in the problem amp, when i connect an rca cable into the rear input, the M25 section sound normal. when i connect

another rca into the front input, strange noises and static throught the M25 speakers.... when i disconnect the rear input

and leave only the front input in, no sound at all in the M25 section.....

to solve the problem quickly, maybe the fastest way would be just replace the rear rca jack and see if it's solved......

i haven't opened the amp yet again to start solving the problem but thought to throw it here into a topic about the rca jack....

it will just save me some work and time..................;;;and time is money................

i haven't measured out anything with my dmm....amp is still closed...........

will be for when i have some time for it..............

there are indeed two types of rca jacks, the normal ones and the self switching jacks........

i just opened the route 66 amp and saw the difference.....

i have somewhere a repaired M44 board with clean rca jacks, i will just switch them and see if

that was the problem...... that M44 is just for parts or repair, so....................................

i found and solved the problem.... i took some pics of both types of jacks......

the left one is the self switching jack.

here's a pic of the self switching jack WITHOUT a rca cable plugged into it.......

here two pics with the self switching jack WITH an rca cable plugged into it.....

you can see good where the connection opens itself............

these pics are of the good jacks i used to replace........... these are for the M series...

i posted the pics here, you never know somebody ever has to deal with the same issue,

i hope this info will give some help here......................;;

my best quess was, that the previous "owner(s)" didn't were very nice of connecting/disconnecting the rca jacks.....

i took pics here of the jacks taken out of the repaired M44 board......

the route 66 is playing back fine now, simular as the other one.......

about the bad jacks, first of all there was no contact between the pins when no rca was plugged in

i could fix that a little bid with some soldering skills.......

in the other front input jack the right rca jack didn't gave ground contact probably for the same reason of

agressively disconnecting the rca's pulling them up and down.... i fixed that with a little 0.2mm copper wire

stripped out of a ftp cable......that m44 amp is just for parts or as a reserve amp so that doesn't matter......

but indeed the problem was inside the rca jacks, not somewhere on the board.......................
