Question about Audio Players & Recorders

1 Answer

Akai 4000ds -left channel pegs when turned on.

When I power up the unit the left VU meter pegs out and begins making a clicking noise due to the fact that it is repeatedly pegging out to the left. How can I get rid of this? Sometimes when I flip the monitor switch back and forward I can make it go away and then it starts to rebuild energy and pegging out again (this doesn't work all the time). Also I want to stabilize the machine, the axis turn really corky and it keeps hitting the tape and adds a lot of wow 'n flutter. Any tips on that?

These 4000 decks are notorious for bad transistors and you are describing a capacitor that has gone leaky. So it can be either of those conditions. There is no easy fix a Technician will have to work on it to get rid of the problem otherwise it will just get worse. All these older machines had capacitors that are at the end of their lives. Too many years on them. The slide switches in them also need cleaning with Caig Deoxit. Other contact cleaners are not as effective.

SOURCE: Play back/recording of tapes

The heads are out of alignment. This is a simple adjustment when using an alignment tape. Realize that any tapes that you record at this time WILL NOT play correctly once the unit is re-aligned. This should be a relatively inexpensive labor only repair.

SOURCE: Sony tape decks model tc-355

Follow the left channel lead to where it joins with the PCB. Use a pointed tool and prod connections if you get a buzz then that stage in the amp is working. I suspect you will find it leads to a IC that might cause the fault. If you find it buzzers on the right but not left, then it's gone. PS don't short pins. If you can get hold of a signal injector it will make things easy.
Be careful and good luck.

How to dub tape to tape


Hi Dale,

You're kind of light on details of the equipment you're going to use - so the best I can do is provide generic instructions. You'll need two devices - one must be able to perform playback for source media and the other for recording or copying duties. Inspect the jacks provided on the rear of both units. Most provide standard RCA type "Phono" jacks for left and right audio channels. Connect a stereo patch cable (with plugs that match the jacks of the playback and recording devices) between the left and right OUTPUT (or "PLAY") jacks on the source device and the left and right INPUT (or "RECORD") jacks on the recording device. Insert the source tape, cd, album, etc. in the device that will playback the original and insert a high quality blank media into the device that will provide recording capabilities. Begin playing the source. Set options such as tape bias, Dolby Noise Reduction, etc. on both source and recording devices to match media in each. Advance the playback source to a point that contain the loudest sections. Set recoding levels by monitoring the VU meters on the recoding device and vary the input adjustment levels so that only the loudest prortions of the program just begin to briefly "flirt" with the 0Db or red zone of the meter. Signals that cause the meter to indicate into this area and beyond begin to overload the amount of information that can be recorded on the blank media and often result in muddy audio quality during playback, later. You should also record the same section repeatedly with differnt options (bias, noise reduction, etc.) to actually hear the difference to determine which sounds best to you. Once levels are set, queue the playback device and start recording. In the case of tape, allow enough recording time to let the leader section of the tape to pass beyond the recording heads for several seconds or more. Once the desired amount of silence has elapsed, play the source program. Allow it to run to completion using both sides in the case of tape and then playback the entire new recording to make sure it recorded without any issues.

I OWN A AKAI 4000DS MK2 REEL TO REEL TAPE RECORDER, IS IT POSSIBLE TO CONVERT MY TAPES TO DIGITAL. WHAT WILL I NEED? THANK YOU


All you need is to connect the Tape deck via a lead to the audio input of your computer. You can then get a audio recording software (I use and recomend Dan Das Digital Audio Editor). It will record the audio and then you can save it to any number of audio formats. There are some basic processing functions on most Audio Editors, but for more advance features get Audio Cleaning Lab, by Magix. You can record direct with this software. But it's easier to import files into it, due to the fact that they have made the cutting functions complex to use, but the special features easy!

There is a loud hum on my 32" AKAI LCD TV on all channels.


The humming noise is cause by defective capacitors in the power supply 12 volts line. These capacitors become defective due to the amount of heat surrounding them.

Denon DRW-585 dual-cassette deck makes clicking sound


There is an outside chance your tape cassett has a static charge. Tape in plastic case of cassette can build up significant electrical static which can partially discharge as tape is run. It can sound like random thumps, ticks, pops ect. Wrap cassette in a damp (not dripping wet) cloth, for several hours, then try again. This can also happen to the reels and drive rollers of the deck
