Topic: ratshack digital signal converter testing :)

[dr.ph0b]

ok, i got sidetracked with a new toy, that i think some might find interesting. especially since its $14.99!!

RS part# 15-1228. it runs on 9v DC, and comes with a wall adapter that lists the output as 9v 100mA. not sure what the amp-hour rating is on a normal 9v alkaline, but i simply cut the adapter wire, slapped a 9v battery plug on it and connected a 9v alkaline to it and its running fine. im testing now, how long it will run off 1 9v alakaline. and grabbed another toy.. also $14.99..  the optical splitter in the bottom pic daisey chain JB3's??


here are some pics:

ok, im up to the 4 hour mark recording coax in->optical out to jb3 with the 9v alkaline...

been using the same converter from radio shack for a whille now.  only really use it to go optical > coax when transfering md for people.  worked great for me so far.

[caymanreview]

those optical splitter can really screw with a jb3 recording

they work great with md decks i hear, but a jb3 is kinda picky and when you just split the light signal like that it causes problems with the jb3

let us know bro, keep us posted

[dr.ph0b]

well its been powered on now for almost 16hours. been recording for about half that off the same 9v.

[Chris K]

any tests for battery duration while recording, or wont it matter? are you passing a signal while testing how long the 9v will last?

again...keep us posted. i would like to use this going mod sbm-1 > jb3

great job!

[dr.ph0b]

yeah.. im recording to my jb3 so ill have official times based on how long its been on and how long its actually recorded.

btw, I use modsbm1->jb3 with the sony 7pin optical cable with flawless results. do you not have one of those cables?  i think sony has some for sale still

i bought  a used one, but it was busted, and confirmed as such by paul at pro digital. you can see the light on the output end but it is not passing signal either way. i got my money back for the cable, thankfully, and i have to return it to the seller

paul at pro-dig said they no longer make the sony cable, but there are a few old stock that already have the mini optical out built in. he said he can still get them for $85 (?)

i was contemplating getting a new cable, but if this rs optical dealie works for you, i may give it a whirl

Interesting b/c when I talked to him a couple months ago he said he couldn't get any more and referred me to Klay Anderson who advertised them on his website but also said he couldn't get them any more.

[Chris K]

maybe paul thought you were talking about the 2 toslink original version, not the newer one that has the mini optical out connector

i was in paul shop when he told me he can still get them

i think i may get one, but this ratshack converter thing still is an option

[dr.ph0b]

ok.. well the battery finally gave out after being on for 20hours. i was recording for 8 of those hours. no glitches or anything even up to the point the battery died. i was expecting some pops when the battery got weaker in the end, but nope, it just cut off. im wondering how much more battery power it would use while recording than it would use while sitting idle? i know the optical light is beaming the whole time is plugged in. 

well i give it 2 thumbs up for some who would need it. price is amazing. very compact, and simple to add a 9V alkaline by cutting ac adapter plug off and putting on a 9v connector on it. (RS sells em in packs of 5)

[Simp-Dawg]

what about bit-accuracy?

[dr.ph0b]

it only converting signal, not the data.

[hoobash]

Does it send signal to the coax and optical ouputs at the same time?? I have the cheap sliver box convertor this looks like it could be a step up
