Hello guys, I have a question for you.
Can I connect the iPhone to Philips D8444 through "LINE IN" and headset exit?
I don't know if "LINE IN" is a function to listen or recorder only.
I wold like to listen the mp3 on Philips.

Thanks

I have that model, and Line In doesn't work correctly. Try adding an external headphone amplifier. If that doesn't work, you're out of luck. Use an MP3 cassette instead.

To stop the deck motor running, put some plastic rod to the circled REM -hole.

This model has really aggressive ALC, so if you got very bassy music, it will lower the volume and starts sounding very muddy. Adding a headphone amplifier may just worsen the experience. I removed the ALC by desoldering one pin from the IC that controls the recording level, and the line in worked very well after that!

I’d be interested in seeing how you did this as I have 3 if these lol

One of my old topics has information about this.

Next thing that I will try, is to cut the pin no. 7 of the TA7658P chip. That's the preamp for the tape deck with integrated ALC (automatic level control).
http://pdf1.alldatas...BA/TA7658P.html
In the datasheet, pin 7 is named as "ALC control input". And I figured it could possibly disable the ALC so we could get the box working better with "Line in"."

Yess! Cutting the pin no. 7 seemed to disable the ALC altogether. Though cranking the bass knob (at over "6" or three o'clock) muffles the treble, but only if treble knob is turned up.

Also one plus side is that it does not need much level on the line-in now. So a lower powered mp3-player should also be enough to get a good volume. These are just based on a few minutes of playing but will test more and update, but for now, seems reeeeaally promising!"

EDIT: Now that I read those, I noticed the thing about treble and bass knobs acting weird. I have to test soldering the pin 7 back on, and see if it has any effect on the tone controls...
