    Otari MX505 calibration help

    I think I have a relay AND a switch problem. SW101 and SW201. Only found one relay on the channel card, looks like RL301. I'm gonna try to clean the relays before I order replacements. I pulled a card and got the relay cover off, it wasn't that hard actually... Should I consider replacing the...

    "soldering finesse" huh? I wonder if i should get the parts, pull the cards and find somebody to do replace them for me. i'm not that great with a soldering iron. there's an old tv repair shop next to the building i work at. i bet that dude could solder them in for me. prolly would do it for...

    did a little research on the relay issue on the MX5050s... yeah, this sounds like it might be a problem on this deck. besides #2, some of the other channels have some weird stuff going on too, little intermittent problems. I can hear some weird upper harmonic distortion tones fading in and out...

    you might be able to get by with something like the Firestudio, I don't know exactly what kind of I/O it has. but think of it like this: for an eight track R2R deck, if want to record eight tracks at once, you need eight pres and eight channels going in. now if you want to listen to the eight...

    not sure if there are other stand alone units like the mackie onyx. thing is, its more of a live mixer anyway, not really meant to work as a front end for a studio recording setup. helluva powerful mixer though. the other option is to get a seperate interface and mixer. as cjacek said, some of...

    are the relays the little line input and line output level switches? if so, yep, I think they are starting to go bad. are they hard to fix? do I have to replace the entire channel card? ch2 is so weird. when I play a tone on input at -10, it plays back at like 0.

    yeah the inserts and EQ and all that is post Firewire out. I use the d-sub recording outs for recording to tape, and that stuff isn't in the signal chain going to tape either. it kinda sucks, there is a mod to change it, I just work with it though. I constantly tweak EQ & comp settings and such...

    you mean you want an interface, right? a "digital mixer" is not necessarily the same thing. if you wanted to get something like an older Tascam mixer, you can get a cheaper interface, something like a Delta 1010LT... there are lots of options. try to figure out what you want to before you start...

    Otari MX505 calibration help

    no, everything seemed alright *playing* the test tape. the bass was a little funky, but I am assuming that is the head bump(?). I was able to measure the output on the XLR outs, and they were pretty close to 1.23 volts at 1KHz, so I think I am alright. right. did this last nite, thats where I...

    are you looking at the mixer for $800? because the FW adapter is a couple hundred more on top of that. It has a little brother too, the 1220, with only 4 channel strips instead of 8 and only one parametric EQ (1620 has a pair). I actually started out with the 1220 a few years back and I got a...

    Hey check out the mackie Onyx boards if you are looking for an interface. I use an Onyx 1620 as a front end for my 8 track 1/2" and it doubles as a digital interface to my DAW running Reaper. Its basically a mixer that has an optional Firewire card that you can plug into your PC. nice pres on...

    + on everything cjacek says, especially about local buys. I say go all the way to open reel and skip the cassette formats though, you are better off with 24-bit digital than cassette. you don't need the converters on the firestudio, though you do need the outboard pres. You might be able to use...

    Otari MX505 calibration help

    having a weird problem with track #2... On all the other channels, I got the same VU reading monitoring test tones from input and from the repro head. so what is going in is pretty much the same as what is coming out. There are some weird bumps down low, 63Hz is up around 2dB and 125 is down...

    Tascam series 70 eight track

    I dunno about sound quality and reliability of that thing, but it sure looks like it would be fun to record with one of those old beasts.

    Otari MX505 calibration help

    OK, makes sense. but if I do this, then it won't be seeing +4dBm at the line output playing back a test tone. but thats OK, because once I compensate, if i DO play a tone at thats actually at 320 nwb/m it will read zero on the VU which will equal +4 dBm at the line output, right? I don't even...

    Otari MX505 calibration help

    just when you think you have something figured out, more questions come up... from one of the Becks' links: Example: Say you want an Operating Level of '+5' on tape, and only have a +3 level test tape. Since 0 VU (your reference level on the RECORDER'S VU METERS) should equal +5 level, you...

    Its a TEAC YTT 1144 test tape, bought as NOS on ebay. yep I think it was the middle tracks on the tape that were not dried out all the way through. I dehydrated the tapes for a couple hours, probably not long enough though, only long enough for the outside tracks to dry out but not all the way...

    any more help here?? slowly figuring this out... I know I need to measure AC voltage with the multimeter, so what is the equivalent to +4dBm in AC voltage on this multimeter?? uh thats not in the manual... and more weirdness... I was able to get all of the test tones to play back about 0VU...

    Otari MX505 calibration help

    so correct me if I'm wrong here... basically, once you get the heads physically aligned, you start to adjust the repro electronics. You play back the test tones and adjust the repro EQ so that your hi freq test tone (10k or 12.5k?) reads O on the VUs, right? and you do the same with the other...
