Question about Audio Players & Recorders

1 Answer

Heads are not turning, therefore tape is not moving.

I have a microcassette transcriber rr930. Heads aren't moving. You can hear the machine trying to turn them but they do not move, neither in play, ff, or rev. Any hints?

This unit is driven by belts. I would suspect that the belts have dried up a bit and are slipping. Replacing the belts should resolve the problem.

To reduce background noise from an audio mixer


when you say background noise I assume you mean the inherant noise that electronics produce. the the first thing to do is to make sure that all you input connections are shielded type, you don't need to spend money on gold plated connections, but do buy cables that are made with stranded wire and of decent size, bigger (fatter) is better when it comes to minimizing high frequency losses. Next, calibrate your inputs one at a time with a 1000hz signal that is 0db inn level. You can find this signal online through a search. you can also buy small plug in devices that produce this signal at 0 db (that is Zero Decibles) this is a common reference for "consumer" grade mixers, If you can't or don't want to spend any money on this you can use a signal from any tone generator, and some mixers have them built it. If you don't have any of the former, here is what you can do. turn all you mixer controls to 0 (zero) detent. in other words, flat, no treble, no bass, no midrange. on your inputs there should be input level knobs, these woule be set to thier lowest positionn if using a line input signal. if a microphone that level would be different, but wait on that for a bit. now have all you input knobs (or sliders) at minimum level. Now turn on your amplifer (if your using one) or what ever you monitor the output with. Headphones is a good choice as you can hear everything.
You should hear nothing. (nothing is supposed to in the inputs yet) if you hear noise take note of what it sounds like. turn the sound output level out (if headphones, turn up to a high level) and listen again. is the noise white (hiss) or hum (low freqency) if you have no noise, you have a good mixer and that is what it should be.
No plug in your first input, this is your choice but I would suggest you plug in microphone, now turn it up to the point where you can hear your own voice, you should hear just that, and maybe anything in the backgroud (furnace, tv, etc_) the quieter your environment, the better you can adjust this. Remember you will now need to turn up the input level. If you have meters you should be able to adjust the input to register in the green without turning red, a litlle yellow once in awhle is ok.
If this is quiet and clean you are ready to move on. turn that mic down to zero, but leave the input where you set it.
now plug in a line level source (your tape player,/cd player/ but don't use your computer as a source (yet). without anything playing on your machines you should hear very little noise in your headphones, if you hear a lot of noise you have bad cables.
Now play something through the tape/cd player, what ever and turn up the slider (not the input) this should give you a level,again in the green, with a little yellow, NO RED
once finished with this turn it back down and go to the next input. this time plug in your computer which most likely is coming from the green jack on the back (or front) of your PC/Mac or whatever. computers are very noisy machines, and just being close to one is sometimes enough to cause noise in a high gain system. anyway, plug in your computer and listen, you should hear some noise and I'd be surprized if this wasn't the source of your problem. make sure your volume level on the output of your pc is set to maximum, this will give you an advantage when recording. now turn up the slider on this input and listen for the noise level. good cables are important here and also the price of your computer may be reflected here as well since more expensive machines are better filtered and therefor produce less noise.
play a sound file (windows audio samples are noiseless and clearn) so use them if you can find thiem, look in your music folder for the sample files
You may hear some noise but your mixer is now set up at optimum and should give you nice sound if it is a quality mixer, good luck, Keith

The receiver is muted when playing in tuner or cd the volume is not coming through the speakers. We can hear it muted when turning up to max its very low. Lost instruction manual can you help. I think my...


I can't find a manual either. Can I assume you really mean the sound is muted for EVERY source, not just tuner and CD?

I'd guess it's either MUTED or a Tape Monitor is active. Turn the volume down, select FM as the source, tune a station and use it as your test source. Look around for indicators that give a clue.

NEVER troubleshoot anything with the volume control turned way up. You'll blow up or damage the speakers and your hearing right after you discover and correct the misplaced control.

Akai recording problem


You might have a bad cable to the recorder (try swapping the right and left connections and see if the problem moves to the other channel), dirty tape heads (use a cotton swab and head cleaner or isopropyl alcohol to clean them), or a circuit problem inside the recorder. Hope this gets you started!

Sound lost


I don't know if this will solve your problem, but I have a question.  Does the receiver sit under another piece of hardware?  Especially one that gives off a lot of heat?  It is possible that the amp or power supply is overheating.  The heat forces the receiver off until it has a chance to cool down.  Then when it turns back on, it starts to generate heat again.  Try moving it out from under any other gear or out from under a shelf so that lots of air can get in the top.  Maybe even try putting a fan over it, just as a test to see if this helps.  I work at a recording studio in Toronto, and we were having the same problem with one of our digital multitrack tape machines (No the studio is not trapped 10 years in the past - we just use tape for backing up and client delivery).  Anyway, early in the day, the unit worked fine.  If we tried to use it later in the day, we would get glitches all over the tape, or the transport would freeze up altogether.  We found that when we moved the unit into a rack where it could really breath, and where it wasn't right under an 8 channel mic pre-amp, that it worked without any problem.  I hope this helps.  Good Luck!

My Marantz CP430 only plays on the tight channel, also it invariably doesn't automatically stop at end of tape but clicks interminably.


I suspect the recording problem is that the wires have broken on the back of the recording head.  The heads move forward every time that a cassette is played and the wires have to bend a little.  A common fault on many cassette recorders is that these wires break with constant movement.  I have a machine with the same problem, but getting to the head wiring in a CP430 is far from easy.

Dictation Transcriber


This could be anything from a bad belt that does not allow the unit to fully engage to a bad motor. Hard to say without seeing the machine. If you feel comfortable opening up the unit, try replacing the belt first.

Hey Tex

You are on the right track, sounds like a noisy volume control. Can often be repaired with a squirt of cleaner spray into the potentiometer assembly.But I suggest you use crc2-26 contact lubricant spray, not silicone spray which is a great materials lubricant, but not electrical. Worst case, the Vol Potentiometer, may have to be replaced. Go for the CRC first and see how it goes. Good Luck, happy FixYa
