Hi, 

The line out from Genos goes directly to the DI input of mp599. Yes I use the same headphones to test both at phones output of Genos and 500R8 headphones output

Hi,

My main instrument to record is Yamaha Genos, using my Tracking lunchbox Heritage Audio OST 8 ADAT, connected to audio interface Cranborne 500R8. From all my preamps when recording Piano, Epiano or Strings (orchestral strings like quartet and symphony), mp599 has the best sound while tracking, but I still hear a major difference between the sound through phones of Genos, than coming through preamp and Audio interface. Could I improve the sound if I use another preamp ? If yes, any suggestions. I am a newbie to this, so am not sure if am making the right call here.

Hi,
after I desoldered, I noticed the legs are too short to switch sides. I noticed the previous link I sent you has a long shipping time, so will this IN914 Diode and IN4148 Si-Diode also work ? They have faster delivery times

Greetings,
Jasper

When I place the final plate, it touches the top of Capacitor C9, is that okay ?. Sorry I could not paste all the images and questions under 1 reply.

Hi,
I think I found my issue, both the diodes are soldered in the wrong direction. I assume this should solve the issue ?.. If incase I damage the part, what terminology should I use to purchase that diode ? . Will 1N914 Signal diode work ?

Hi,

I replaced with another DOA, which I already have and I must say the mp599 sounds so good , but unfortunately my DI (High Zi) is not working. When I connect my bass guitar, the XLR input behind, gets cut, that works fine (I can also hear the relay click when I insert my HiZi cable), I do not see any input signal. Is there any thing I could do ?

Hi,

sorry for the delayed response, I just got my tester kit fixed. I noticed, without DOA and DI board, with Jumper on JMP1, I get around 5V between 0V and TP2. When I connect the DOA, the DOA gets really hot and I smell something hot. Is there something wrong here ?

MP599 Microphone preamplifier / MP599 preamp not working

Hi,

I built the preamp based on the assembly guide. I forgot to perform the tests from the setup guide and when I connected to my Wes audio chassis, everything was fine (no smoke). My Wes audio was not connected to my audio interface, so I connected it to my Cranborne 500R8, the DI input did not work, I saw line level input signal and LED blinking, but no output signal and within a few minutes, I saw smoke, I removed the module and am not able to find which component emitted the smoke. Also the preamp is not working. Any suggestions on what I can do ?, or how to fix it ?
