Title: copy prohibit message on a d-8 ??
Post by: junkbondking on March 07, 2005, 01:14:17 PM
in the dat chain i was running for the JJJ show @ the bluebird on friday i had the bands d-100 out of my hosa splitter going intoa d-8.  the d-8 was flashing "copy prohibit" in this position, so i swapped it with the d-100 and it still flashed that message.  anyone know why ?  i ended up tossing the d-8 anyway as i figured getting the band a copy that nite was not gonna hapopen unless i put them first in the chain. 

i could use the info later as im sure this d-8 will be seen again in the section.

saw that one, but it is for a d-7....

Yeah....but I've had the exact same issues with a D-8 and a D-7. I tried both decks and both gave me the same copy prohibit message.

then i suppose thats why... also why i run a nomad jb3 as well.....

you sure the tape loaded in the d8 didn't have the write protect tab in the wrong position?

What was the signal source?  If it was aes, that would likely be the cause (though one would think that a consumer d100 would run into the same problem -- an m1 would of course ignore scms -- or the false-positive scms issue caused by an aes signal alltogether)

I was running on a 24 bit signal out of a v3. I'm 100% positive that the tab was not pulled back. That's the first thing I checked.

Yep, a D7 and a D8 are basically the same in this regard.  Check the other thread for more info.

Also, which output were you running the chain out of on the V3?  And if it was out of the AES1, what were your jumpers set at?  This might help track things down.  Though I'm with Darrin -- strange the D100 had no problems.  If it were an M1 it would make sense, but the D100 has the same copy prohibitions as the D8.  Maybe the D100 is more tolerant of a 24bit signal than the D8, though.  You sure you had the ANSR circuit engaged (ie, were running the V3 at 16 bits not 24 bits)?

7's and 8's will not take a signal from a dap1 or m1.  that's why you frequently see two chains running

they are pretty much identical decks

everything was fine on the jumpers and ansr was certainly on (it always is) i betcha it was the tape.  the dood with the d-8 had arrived with 3 tapes and prolly had not changed the tabs.  i just thanked myself for selling my d-8 a year and a half ago and buying a jb3.

Not true in my experience.  Other than copy prohibit problems (eg with AD500>P1>D8 when the AD500 jumpers were not set correctly), I've never had problems running a D8 behind a P1.  Done it many, many times and it has always worked.  P1's are prone to have jitter problems, and I've heard that with too many P1's in a row, a D8 behind all of them may not get a usable signal, but it isn't a problem in general to go P1>D8.

D7/D8's need a higher voltage to read a digital 1 than do D100s/M1s.  Consequently, a D100/M1 puts out a lower voltage signal than a D7/D8.  Normally, this means that a D7/D8 cannot read the signal out of the D100/M1.  An active cable, used on the D7/D8, is meant to get around this.  I have on many occasions run a D7/D8 behind an M1 when an active cable was used on the D7/D8.  I've always had it work for me and have never had a problem.  I have heard many people say that this didn't work for them (M1>7pin cable> coax cable> ACTIVE 7 pin cable> D8), but I've never had it not work for me, so I always wonder what the deal is with those people.

Yeah....I actually ran a D-7 out of a DA-P1 about two weeks ago with no problems.

I've seen this problem running certain decks off the AES output on my Mini-Me.

AES problem, is my guess.  if i try to AES > d8, i usually get the copy prohibit msg.

my d8 was never able to get a signal from a p1.  oh well.

that's because the aes on the minime is pro.... only pro decks can be run in that chain (p1's, hhb's, d10's, m1's).

and fwiw, if youre running abunch of d/7/8's, you have to go d7>d8>d7>d8 to get consistent levels on each deck  :P

yes, I just had this happen last night...so I fed a P1 first then went out of P1>D7 and still copy prohibit....guess the P1 passes AES signal.

my d8 was never able to get a signal from a p1. oh well.
maybe you were feeding the P1 an AES signal ???  I have patched out of P1 w/ D7 prior....it must have been s/pdif
