Pro Audio Repair & Modifications

RME forced to use other chips for the foreseeable future

Global chip crisis with extreme never before encountered production and distribution challenges.

Apart from that, at the end of 2020 a fire destroyed AKM's production facilities for AD and DA converter chips. A resumption of production and thus availability of these components is not expected before 2022. Therefore, many manufacturers - like RME - are forced to either discontinue products based on AKM chips, or to use other chips for the foreseeable future.

Studer A807 Mk 1 Software 30/88

Machine had fault were 50 V fuse kept blowing. I think that was loose reel turntable causing the Reel drive to crossbar the supply, whenever it got out of step. That sorted, but now unable to align the Audio.
Unable to get any change in adjustment parameters in Level, hf for Repro Sync and record. All speed, All eq.
BUT can control bias level.
It was storing tape position. ( Latest test, seem to indicate that no that is not happening, but unsure about the reliability of this test).
My fear is that it a faulty MCM2802. eeprom chip.

Help ISP decimator pro rack G guitar convert to stereo mod version

hi everyone, i have an isp decimator g pro rack guitar version, for my marshall 9200, jmp1, jfx 1 configuration i would need the stereo mod version, i tried to look for used ones, but i couldn't find any. Opening the frame of my decimator I noticed that there is the possibility to convert it from guitar to stereo and vice versa. At the top left is indicated a legend of the position of the components that must be added or removed according to the version to be obtained, the problem that the values of the individual components are not described.

Female TRS wall jack for a speaker connection?

Hi, I'm currently wiring up a couple of panels for a wall in a studio sound booth. The panels are already loaded with female XLR and female horizontal TRS jacks. I would like to designate one of the 1/4" TRS jacks for an amplifier to speaker cabinet connection.
Can I use one of these existing female 1/4" TRS jacks for a speaker connection if I wire it with two conductor stranded 16 awg? Or will I need to replace the jack specifically with a speaker 1/4" jack?
The remaining jacks will be wired with shielded three conductor 22 awg.
Thanks.

MXL 770 quiet and loud hissing

Hi!
My MXL 770 is very low volume and there is a noticeable hiss.
I haven't used it in a while and the last time it was on a different computer and it worked fine.
I use a Neewer 48V 1-channel phantom power supply.
I am not very experienced in troubleshooting this kinda stuff so if anyone could help me thatd be great!
I put an audio clip so you can see what I mean.(gotta crank the volume)

Marco made me think about mic mods

I've been watching with (originally) sum scepticism on the mic mods but I just watched and listened to the MXL Marco swapped the capsule in, and have started to think a bit. The 47 diaphragm the Chinese are making pops up quite often, and in every case - it seems to get positive comment. Going to the Neumann YouTube videos, I've been looking at how they're made and come to the conclusion that maybe, it doesn't sound good because it's Neumann, or AKG or whoever, but simply because the design is good at being nice to listen to?
