what up everyone...

 

i bought this box a few years back.  ever since i've had it, the line-in never worked when i plugged in an ipod.  however, when i plug it into the line-out, and put it in radio mode, music from my ipod comes out and the radio stays silent until i unplug the rca cables and then i hear the radio.  the same thing also happens when i have it on cassette mode and press play.  is that normal?  does anyone have advice on fixing this problem?  thanks.

The RCAs are for recording from an external source, there is, AFAIK, no facility to use them for any input that isn't going through the record preamp so from what you said, this sounds as though it's working correctly. :-)

Why would you need to clean anything? It's behaving exactly as expected for a box with no line input other than when recording to it.

Try it with most boxes that lack an "aux" position but have line level outputs and you'll see. :-)

If you set it as line in you should be able to play through the record/play of tape deck with the function set to (radio off/ cassette on) as stated. But my understanding was it was not working in this mode so in cleaning the line in switch could help. Actually from the looks of it cleaning all the switches would be beneficial ;-)

Ah, I see. The set in question doesn't have a line level switched input though, hence my comparing it to others where the outputs can work as switching inputs with the radio on. And yes, cleaning stuff is always worth doing. :-D

I believe there is an RCA line in for recording, that's why he stated it never worked. This unit has both in and outs but maybe line in was never used by pressing record without tape in player ;-)

i can't press the record button without a tape in it and i haven't tested it out with a blank tape in it yet either so i can't say for sure that it doesn't work for recording purposes.

 

i have a few other boxes that have rca line in's and outs and will play just fine without having to insert a tape and pressing record.  as long as i set the mode/function switch on top to line in or phono or whatever.  so that's why i was confused when someone said that the rca's were for recording.  basically, for this particular box, it is normal to not be able to hear what's plugged into the line-in unless i am recording?

To press record without tape there will be a record latch at bottom inside right of deck (as shown in pic). With door open and no cassette hold it down and press record ;-). Some boxes have a regular line in which is part of function control but this one only has line in for recording :-)

Yes, but why worry when all you need to do is plug the source into the RCA line level outputs and doing so switches off whichever other source was selected? ;-)

 

This might seem counter intuitive but it's not uncommon and isn't a glitch, fault or failing of the device.

My Hacker RPC1 was designed that way and even boxes with RCA input selection at the lower level for moving magnet cartridges usually work at line level through their outputs when connected up like this. My large Toshiba 3 piece does this as well, no talkthrough, no distortion and I'd bet that your Panasonic set is equally clean this way because it's wired to do that. :-)

the level LED's don't work when you plug the source into the rca outputs.  you don't get the full effect  :-) .  i'm just being picky, that's all.  :-)

 

 

thanks john, thanks bill

The sleep function usually works when you're playing a cassette and when the cassette comes to the end it turns off the power to the boombox.

OK thanks.  I always wondered what the sleep functions were for on boomboxes.  I always hope that it will be for the radio function to turn off after a certain time.

On some of the high-end boomboxes they have a sleep timer which will actually do that.

I just tried it and when you put the sleep function on it does nothing until you engage the cassette player, then when you do the radio comes on. When the tape gets to the end and the automatic stop disengages the tape player button and the radio shuts off. Love it. Thought it would be kind of redundant if it was for the cassette to play as you would just use the cassette function for that.
Thanks.

Nice one, interesting that the full auto stop is critical path to the radio as well.
