    Tascam 388 - Hi Pitch sound from headphones / stereo out,

    In more good news, there was an issue where the left channel was outputting hotter than the right. That’s fixed too, so must be isolated to the Monitor PCB

    Tascam 388 - Hi Pitch sound from headphones / stereo out,

    Ok, popped it all back in. Swapped the Monitor PCB with the other machines, cleaned up some spots on the back with Isopropyl & Carefully dexoxit-ed (wrapped them in cloth when I sprayed to clean up any excess) all the snap on connectors and the inputs for the bus pcb and whatever else I could...

    Tascam 388 - Hi Pitch sound from headphones / stereo out,

    thanks! I’ll swap the cards today and report back. re: Cap: Here are pics of what I mean. Like the Cap is surrounded by clear plastic. It’s the only one on both of my machines. Never had trouble with this card though and it’s not bulging but wanted to pull it out to have a look. Is this a...

    Tascam 388 - Hi Pitch sound from headphones / stereo out,

    Ok I’m adding more for reference. Got both the cards out and cleaning up the ‘good’ one (AU machine). Interesting that the Australian one seems like an older revision. It also has these white jumpers on the underside of the board. Any clues to what they’re for? The US one is definitely brighter...

    @sweetbeats this is the card, right? Might test all the bus pcb solder joints while i'm in there too

    Tascam 388 - Hi Pitch sound from headphones / stereo out,

    Ok, so i've been spending a bit of time with the machine trying to figure out some hum issues, trying to figure out if it's the machine or cables and the hi pitch sound went away for a day. It's now back, but only comes on after operating for a bit. I'll give details on what's happening...

    FMR-REAL NICE COMPRESSOR CONNECTIONS

    Does the 424 do the same track as the 246, which takes an insert plug for fx inserts? So a single trs type plug split into two ts plugs

    Recording Through a Tape Machine

    I’m currently working on a project where I’m sub mixing songs recorded into Logic Pro down to my 388 then mixing down to a stereo file back into logic. Definitely adds a tonne of vibe but I prefer the workflow of recording to tape first. Just a preface as I’ve been thinking a lot about this...

    Tascam 388 - Hi Pitch sound from headphones / stereo out,

    Sorry, meaning the monitor card. I've read before of people having issues with the 388 mixing down unevenly, favoring the left or right more. I've never worried about it as I can just pan it flat when mastering, but wondered if the monitor card would affect the balance of the output in both...

    Tascam 388 - Hi Pitch sound from headphones / stereo out,

    Wont get a chance to do this till the weekend, but was wondering could this also be the cause of my left channel recording out at about 6db higher than the right on the stereo & monitor outs?

    Tascam 388 - Hi Pitch sound from headphones / stereo out,

    Ah got it, thanks! Can I get to that one through the top panel, or need to flip it over? Havent delved deeper than the cards up under the lid

    thanks, is it 47 in this pic? Says it's the Monitor SW PCB

    Tascam 388 - Hi Pitch sound from headphones / stereo out,

    Might try and swap the monitor pcb with my back up unit. I’ve found the monitor SW pcb in the schematics but not the monitor pcb. Anyone know where it is?

    Wattage requirement for the Tascam 388? Looking for a step down transformer.

    I’m just trying to figure it out, and I’m not an electronics guy but keen to learn. 60hz hums are usually from power so I thought that’s a place to start. I’ve since tested it with another step down and it has the same hum, so maybe it’s not that anyway. I’m going to try a different outlet...

    Tascam 388 - Hi Pitch sound from headphones / stereo out,

    Me again! So further on the same problem of my 60hz hum, there's also a high pitched sound when I crank the outputs, which is audible in my mixdowns. I swapped the tape over to my spare 388 and luckily it's not on the recording, just in the monitoring & recording down of the audio. Anyone...

    Wattage requirement for the Tascam 388? Looking for a step down transformer.

    Hi, I've got a 60hz hum going with my tascam 388 and think it's the crummy step down transformer i'm using (USA machine 120v to Australian 240v). We've got a place in Australia that makes great transformers, but just trying to figure out my wattage requirement before ordering. The manual...

    I rue the day when this messageboard goes offline. So an incredible resource.

    Listening to the track you’re punching in on the Tascam 388

    Big newb question but I’ve followed the manual and figure this mightn’t be possible but can you listen to the track you’ve got armed to punch in on until you hit record? Or do you just need to have the selector switch in Line or Mic mode and not hear the previously recorded track?

    388 Track 5 'Right' pan doesn't work till I crank audio into it

    I've read about this issue before, but now it's happening with my machine. Basically, Track 5 will intermittently only playback in the Left channel, but if I hard pan it right, turn up the volume and eqs it'll break it free of whatever problem it has. Track 1 also does this, but no where near...

    Replacing Power Supply of 110v Tascam 388 with a 240v supply

    I thought i'd post a seperate chat to not confuse my other thread. I've got 2 x 388s, one on USA voltage, and one Australian. My USA voltage unit is the better one, so I want to swap it's Power Supply with the Australian one, as that's where it'll be used and i'd love to not use an external...
