mp3 cable for SL45 - GSM-Forum

mru · 12-23-2002, 16:05

Hi friends!
I just make reduction stereo cable from telephone to 3,5 audio jack. The pinouts on the phone are:
2 - Audio RIGHT (called SB)
11 - Audio LEFT
12 - GND
Have a nice Christmas and New Year!

how about impedance? are u sure ur speaker is match with phone?

I placed two capacitors 10mikro Farads to the outputs.
You can connect phones directly but capacitors will
be more safer to any damages.

Hello again friends.
I want to use sl45 for listening mp3 in the car.

Here what I want to try:

1. The syncstation of my sl45 connected to cigarette lighter for charging while playing mp3 in car.
2. 3,5 female audio jack out, from the syncstation to line-in of the car-audio system (or a cassete adapter maybe)
3. The system will also have to work as open speaking system when receive calls (e.g. listen to caller's voice via car speakers)

All the trouble is the making of the 3.5 audio jack out. Is it safe to follow the following schematics ? :
(2 - Audio RIGHT (called SB)
11 - Audio LEFT
12 - GND)
and bridging pin 1 and 8 ?

All the above inside syncstation connector

About brigding wich is the right ?
pin1 and pin 8
or
pin 1 and pin 7

regards!

Try, you will see. I thing pin 8 to GND for recognize HeadSet and
pin 7 to GND if you have external switch to hang up/down a call.

2 Audio RIGHT (called SB) to +| |- to RIGHT jack
11 Audio LEFT to +| |- to LEFT jack
12 Audio GND to GND jack

+| |- is capacitor (I used 10uF / 16V). It is not necessary, I thing you don't need it to connect.

After this, you will hear Caller voice in your (Left or Right) Speaker of CAR-audio system. (I don't remember now)

Post here results, please, because some people still have questin about this. Good Luck my friend! Live in peace

Quite right:

pin 8 + pin 1 for recognize plugged accessory as headset
pin 7 - button - pin 1 for PTT button

pin 2 = + audio left
pin 11= + audio right
pin 12= - audio

pin 9= - microphone
pin 10= + microphone

I don't use it and it works. Why you suggest to use it?

Enjoy it!

Hi Lerry! Thank you for clear info. Nice! I used capacitors because it is possible to short pins of 3.5 jack F/M when you connect it together. And short outputs of Power amplifier is not good thing, isn't it? But you are right, it is not necessary because amlifiers have this capacitors on output usually included. So I put it only for be sure. Heva a nice day!
