Tone Direct Problems

I just moved into a dorm room and for the first time I've started having problems with this unit. The tone direct keeps turning off and on by itself randomly and periodically while I'm listening to music. As you can imagine, this is very irritating. I try to push the power button on the machine itself but that doesn't work. I have to use the remote to turn it on and then I can push the button on the machine to turn it off. When I go to push the tone direct button on the machine, it switches to VCR.

If you still have warranty, use it.....!

The board for your preamp/switch/vol are made as an electric matrix. This means that several signals are coded and sent from the "frontpanel" to the amp itself. A digital signal like this will be hard for someone to measure and understand without a oscilloscope.

My advice is to clean and check all connetions (inside the amp), but mind the hazardous currents inside.

Generally if you wanted to send a fax to a facsimile which is connected to an must dial only the direct line number and ask operator to transfer this call to fax (wanted extension).After you heard the fax tone you can push start button.
If the fax machine full-time connected to same extension & dedicated direct-line there only for faxing,we can program the pbx for automatically transfer the incoming fax or call to that outsider have to dial only direct fax number without ext no.
Only Panasonic PBXes having a unique feature if i'm wright if it detect fax tone from any direct line it will automatically transfers towards fax extension.

ION Profile LP Vinyl-to-MP3 Turntable, tone arm won't drop

I've got the same problem. When you put therecord on, spin it from the centre, and it will release the mechanism inside,this is what I do, and it works fine. I think the problem is that there are twoplates under the turntable, and there was grease between them, after a few goesthe grease disappears, causing the problem.

I've just set up my Technics SL D212 turntable after moving house. It keeps skidding across records. I've tried the usual adjustments and leveled the turntable. Any clues?

Please make 100% certain the needle is still in place... To test this *GENTLY* rub your fingertip over it and you should hear noise from the speakers when you do. If there is NO noise then there is likely no needle.
Did you put the protective device on the needle/arm for the move? Is it still on there?
Sorry Mate, that the only thing I've got to help....

I have a Wurlitzer one more time. vinyl record jukebox.. I moved ( or turned) the turn arm forward to clean behind it and now the records will start to play and return to the changer. How do I adjust it.

Look up underneath the mechanism. You've moved the tone arm with respect to the bracket beneath it (which closes the trip switch). Select a record...turn the machine off...then look up under whilst someone moves the tone arm and you will see what it is attched to. If you are lucky you can hold that tight and gently move the arm back the other way a bit.

Didn't you get a manual with either one?

Page 29....

>>> Before using the receiver for the first time, initialize the reciver by performing the following procedure. This procedure can also be used to return settings you have made to factory defaults.

1 Press POWER to torn of the receiver.
2 Hold down TONE MODE and 2CH/A DIRECT and then press POWER to turn on the receiver.
3 Release the TONE MODE and 2CH/A DIRECT after a few seconds.

After "CLEARING" appears on the display for a while, "CLEARED" appears. <<<

See if that helps.

Tone arm pulls in one direction

If the force is towards the center of the disk, it's OK, it's the antiskating force. Set antiskating at 0, set the weight at 0gr, turn around the makeweight in order to set the tone arm parallel to the disk. With the antiskating at 0 the tone arm will stay parallel to the disk in the place you leave it. With the antiskating at any other position the tone arm will stay parallel to the disk going towards the center of the disk.

In case of a problem or clarification, don't hesitate to post.

Thanks and regards

Is this only when using external inputs? The manual says the Tone Control will not function in Direct Mode. Try Stereo and various DSP surround modes to see if the Tone Control works.

Dear Sushant,    I do not think your use of an equalizer has caused any problems.  I will explain the proper use of the source/direct button.  This button's function is to monitor the output of a recorder connected to the record outputs of your amp.  When this button is pressed on the sound going to the speakers comes direct from the "source" (cd, radio tuner, phonograph etc.) when in the off position you can monitor the recording of whatever source is being recorded via the tape deck.  This switch must be off to record through the amps record outputs.    To test this, put a blank tape in the tape deck, choose the source as phono and place the dec in record/pause.  With the source direct button pressed on you should hear a change in volume when moving the amp's volume knob only.  When source direct is off you will be able to hear the output of the tape deck, so adjusting the tape deck's record level will also affect the volume coming out of the speakers.  more record level in/ more level out.!    Below is copied from page 9 of your user operation manual for Marantz's explanation of the source/direct button.  image.tiff
best of wishes, Michael Mittelsdorf
