Tascam DR 05 anomaly

I use a Tascam DR 05 to record my mates acoustic guitar and my bass in rehearsing some of his original material.I'm through an amp and hes playing and singing acoustically,My problem is that on playback,the playback sounds like it has an added 'tremolo' effect,emphasised at the bass end. We've tried different locations for the Tascam but that same effect is still there,I have discovered that the 'Tremolo' effect is only there when I use the 'headphone/line out' socket either into 'phones or straight into a stereo amp.If using the USB socket into my PC the recordings are 'clean' with no weird effects.What could be causing this?
 
what cable are you using to plug the line out into your stereo amp? do you have the same issue when plugging some other source into this stereo amp? also do i have it right that you'd heard this in a pair of headphones plugged straight into the DR-05? do you have a recording of this what this "tremolo" sounds like?

could be a bad line/headphone out on the DR-05, but impossible to provide definitive answers based on the info you've provided.
 
Not sure how long you've had your DR-05, but that's an older piece of gear and could be developing issues (the DR-05x is the newer model). The fact that the USB is working fine and the line out is problematic would suggest that you either have an issue with the circuit or a line level issue. I'm sure that you have tried the volume control. I always downloaded my music from the unit via the USB, but there are effects that can be applied during both recording and playback, this is from page 43 of the manual (see below).

Cheers...

FYI: My 10 year old DR-05 was a great asset for band practice and recently died. I replaced it with a DR-40x and I love it... it offers 4 channel recording so you can use the live mics and output from the sound board.

I have a DR05. I've only ever used the headphone out to check what I've recorded afterwards, and that works fine. The device is only doing one thing at a time, recording, or playback.

I suspect when you ask it to do both at once, there's a voltage drop going on that causes the tremolo problem. It doesn't do it on USB because it provides the unit with additional power.

But I'm only guessing .
 
I have this same problem. When I first started using it, things were fine, now everything I record, whether solo Bass or with Guitar, Drums, and Bass, the Bass always plays back with a tremolo effect. I became frustrated and stopped using the Tascam.

Sorry you are having issues. I don’t have a DR 05, but a DR-07 mk II. I’ve not experienced the kind of issue you are having so I’m not sure I can help.

That said here are some things I would check out. Is this a new symptom? Are the batteries up to charge? Do you get the same results with a different data card? When recording, does the sound level indicator flicker or go up and down? Is it maxed out?

If I remember correctly, mine has a limiter on its microphone so the input signal will not distort. I believe this is adjustable . To rule this out, reduce your input gain to about half and see if that doesn’t eliminate the problem.

I hope this resolves your problem. These a great tools to “monitor for quality assurance purposes”. I’ve been recording gigs and rehearsals for the last 20 years and reviewing what I’ve played has made me a much better bassist. What I get out of a review is understanding and identifying what I need to work on so I’m not spending time on things I don’t. Individual practing is much more focus and ver efficient.

From the band side, a recoding is worth a thousand words and it’s the unvarnished truth. Pretty much it eliminates squabbles over musical conflicts, and it also provides a standard of your arrangements which is real important as players come and go. All you do is give them a copy and they learn it on their own time not your and or the rest of your bandmates time.

Best wishes.
