Tascam 238s - bad recording track

Track 1 plays things I've already recorded just fine. But now when I try to record new material on track 1, I get mostly crackling, scratching, poping noises. I read somewhere to try removing and reinserting the channel card. This didn't do anything. All other track still record and playback correctly.

    My M-529V won't paly or record, but it works (everything enges and moves) like you would think it was going to do something. Speaker hisses like it working too on high volume setting.

Hi Folks, I think the problem on Tascam 238S-Decks
are bad cheap electrolyte Capacitors. Acid gets out an destroys the solder points and PCB tracks.
I found some smeary liquid an the PCB, where it is affected.

You also find bad leaking caps on the Korg workstation W/01-fd.
good luck, Jo.

Hi,You should get a copy of the schematic and a scope and meter and trace the signal flow.This is assuming that the power supply lines and switches are all ok.Usually a switch is tarnished, sprung or just simply dirty.first clean all contact fingers,switches and check ALL connectors and clean them. Transistors and chips rarely go except from age and manufacturing.It's most likely somethig simple like dirt or tarnish.Try GENTLY rocking each connector and MAYBE cleaning with tuner tonic
or alcohol. If Switching or crosspoint chips are used, measure control pins versus input and output pins. I can not stress enough logical and methodical troubleshooting technique to solve the problem Best of sucess,Mike

Sounds like record play switching problems. Spray the record play switch internally with crc 2-26 and operate 20 or so times to work in the good stuff.

Being older I recall these recorders. The problem with them was 8 track tapes never played very well due to the cinnamon roll design, the recorder and players tuck the tape back into the center of the roll when playing them. This poor design causes them to wear out fast and often snag or damage the mechanisms. Not to mention you can often hear adjacent tracks spilling over into the current track you are listening to...

In your case I think the recording head which records track two is out of allignment or contaminated with oxide from the tapes which tends to cake on them. You might try giving it a blast of compressed air if you can find the recording heads, or if unafraid cleaning the head witha q-tip in denatured alcohol or a commercial head cleaning solution for old magnetic tape machines, the solution is basically alcohol and something like freon to make it evaporate if I recall correctly.

If it still doesn't work it is probably because these things are very old regardles of how well they were made in addition to the fact the technology is 40+ years old.

How to record with Multi-effects feature on Tascam DP 01

I'm not familiar with the Tascam DP-01 but many multi-track recorders don't commit effects to the track until the mixdown phase. The thinking being that you cannot eliminate a "bad choice" effect once it's down to tape (old school term) and so they allow adding the audio tweaks at the final stages of recording. Here they hope you can appreciate the entire mix and then decide what sweetners to add.

Hi folks :-) I'm affraid that we have started up wrong, but I hope we can fix it ! Problem: A band, we've made a que-track (everybody's playing and singing at the same time) now we've...

Real musicians do change tempo throughout a song, so its not necessarily a bad thing. As long as you like the sound it doesn't matter if you don't stick rigidly to a fixed tempo. Unfortunately you won't be able to fix the tempo after the initial recording so you'll have to live with it or re-record. If you need a click track to record along to, try recording yourself hitting drum stick together along to the already recorded track. As a human you can track small tempo changes much easier than a computer. If you need to create a count in, just copy and paste a section of this click track to the start of the track. I hope this makes sense!

When i record and try to play back i get nothing dpo2 . 2 tracks armed. i stop rewind and play and theres nothing , headphones can be heard when recording

Very likely the over-write head does no longer function properly. Try again with a MD that already has recordings on it, try to record another track to it. If the entire disc seem blank after TOC was written, the OW head is bad. At this point the unit effectively becomes a player only....

Tascam 8 track recorder won't play back recording

Does it use MiniDiscs? If so, it cannot work with standard audio MiniDiscs, it requires a special DATA MD.

Can't erase?

Do you mean it will record new material but not erase the old, or that it will neither record or erase? Can you play old recordings?

Try removing and reinserting the flash card. If that doesn't fix it, try a new flash card. If that doesn't fix it, you need to take it to a qualified technician.

Having problems recording and playing back tascam dc-02 cf

I'm assuming you are plugging the left and right outputs from the karaoke machine into input A and B of the Tascam to record the stereo output of the Karioke. The Tascam works with mono only (you recreate the stereo mix at mixdown or when bouncing mono tracks together with the panning set). Therefore you should be assigning inputs A and B separately. You could press assign A and then the record button above track 1 and then press assign B and the record button above track 2. Then arm tracks 1 and 2 (by pressing record above each). When you then press play and record together you'll record input A onto track 1 and input B onto track 2.

Hope this helps.

Just bought a DP-02 w/40gb hard drive


You'll first need to find some aux audio out jacks on your karaoke machine. You might need an adapter, but the basic idea will be to connect the aux out from the karaoke machine to an input on your Tascam DP-02.

Then on the DP-02 you need to assign whatever input your plugged into to one of the 8 tracks. Let's say you're using the left input (input A) and want to put the karaoke music on track 1. You'll press the 'Assign A' button on the DP-02 and while holding it then press the 'Rec' button of track 1. The 'Rec' button will flash rapidly to show its been assigned. (for reference: assigning an input is better described on page 23 of the manual). Then you'll want to arm track 1 to record. Press the 'rec' button for track 1 and it will start to flash slowly to show it has been armed for recording. Now you are ready to start recording. On the DP-02 press the large round play and record buttons on the lower right together to start recording and start your karioke machine playing. When the song is done press stop on the DP-02.

Now to record your vocals you'll need your mic to be plugged in (lets' say it's in input B). You'll need to assign this input to a free track (track 2). Press the 'Assign B' button and while holding it press the 'Rec' button for track 2 (rec button will flash rapidly). Then you'll want to un-arm track 1 and arm track 2 for recording. To do this press the 'rec' button for track 1 so that the light goes off and then press the 'rec' button for track 2 so that it flashes slowly.

So now when you press play and record together to record, you'll hear track 1 playing (the karaoke track you recorded earlier) and you'll be recording vox on track 2. Of course you'll also be recording whatever you hear in the room onto track 2 along with your singing, so in order to get a clean recording there (prevent bleed) you'll want to plug some headphones into the DP-02 and listen to those as you record.

That's pretty much all there is to it. Some variations if you wish to record the karioke in stereo vs mono (I gave you the instructions for mono here), and you may need to turn on phantom power if you have a non-powered mic, but the idea is basically the same.

Hope this helps.

Good luck.

I shut down the system, waited 30 seconds, turned it back on, and the recording went fine. Must've been a glitch.

Tascam Us144 and Sonar3 problem!!!!

Try this experiment:  Record a click track on track #1.  Record track #2 of the output of a monitor speaker playing track #1.
Now you have two click tracks which will probably not be cooincident (like they should be).
Measure the offset of the two tracks!  You now know your latency exactly, and can compensate by adjusting settings or moving the vocal track back manually that many milliseconds!
