Bluetooth Echo with MS-8
I've got the hi fi stereo in my 1.
Used technics adapter to wire up my MS-8, so the line level inputs for the unit. The sound improvement in the audio is adequate for me. However, I've now gotten an echo in my blue tooth. I can't hear it, but the caller on the other end can. It's not absolutely all the time, but nearly every call my wife says. I searched, and saw some posts on it and tried to read through the 180 pg thread on diyma but after about 10 pages from 130 where it seemed first mentioned i gave up... Wondering if anyone else has had similar issues and found a fix. Thanks Joe

I skipped the initial 50 click volume calibration and run the MS-8 at -20db.

then i read this and ended up with good sound. http://www.e90post.com/forums/showpo...&postcount=118 but the BT echo. I have the HI FI (non logic headunit, so i should have the balanced inputs. I skipped the input sensitivity selection or whatever, but did do the calibration as per the manual. I did calibrate at -20db. It seemed ok initially but has been worse lately. Been in car for about 2 mo. Or right after the hi fi harnesses shipped. Joe

Try calibrating at -30dB. Also, do not use Logic7 processing if there is no center channel in your setup. |

In my testing turning off the processing completely removes any echo.
We did a 335d recently with HK, added MS8 to OEM speakers, and had an amp on the underseats and the trunk sub. We tested for echo by calling the vehicle owner. HE heard it, he deemed it not bad at all and not objectionable. I usually calibrate at -40 JBL says if you can feel the sub, it's too loud for calibration, BTW. |

Andy loves Logic 7. I am also in the camp that says that if there isn't a center, L7 isn't helping much. BMW rears don't seen loud either way, so his comment seems aimed at cars with larger, louder rear speakers. And since L7 seems to make the echo appear and disappear, it should be one of the first things you test, I would think...

I haven't heard it for myself, but according to my wife the echo is eliminated after turning off Logic 7. I guess I misunderstood VP when he suggested turning off "processing". I thought he ment the actual Processing option which would basically bypass the MS-8. Obviously that would not be an acceptable solution.
