Hey Everyone!
I'm a newby here - just joined this second!!
I've been using a 48-OB for about 13Years! So I'm a newby to forums but an oldby user of a 48 haha, yeah ok that wasn't funny, anyway I just had to reply to SaintGeorge about his "pin3 hot" problem.
I'm not sure if mine's pin3 or pin2 hot but this won't effect whether the XLR's work or not.
What I found a few years ago with mine is the XLR outputs didn't work. (I always use the RCA's normally (home studio)). What you'll find is on the audio cards is a pair of 'IC' looking relays (one for RCA and one for XLR) which mute the outputs when the unit's turned on or off. On my unit, for some reason, all the coils on the XLR relays had open-circuited. The RCAs are all fine. The hard part here is finding a replacement. TEAC Australia (Where I live) don't support the 48 anymore so I ended up by-passing the relay circuit with a link. All good!
Hope that helps.
Oh yeah, just had to say since owning my 48 I've only ever had Ampex499 then Quantegy Gp9 on this thing aligned to 355nWb/m and it's fat city. You can still peg the meters hard, in fact it's hard to find mixers to drive any signal hard enough into the thing to get tape compression. I've had to modify my mixer to get more drive out of it, haha. Or could use 456 to get more compression if that's what you want. I'll soon be trying some RMGI formulations, even sm468. I've tryed that on my two track and it sounds good when compressing.
...And for what it's worth the 40 and 50 series were "PRO" machines. Mine came out of a TV -post production studio.
Cheers guys/gals
