Hello,
Anybody can help me figuring out how to perform some test to my Neumann U67 using the calibration input, in order to check proper frequency response of the amplifier? I suddenly have very low (no bass) distorted output on all patterns.
PSU is not original but custom built to specs, worked fine for years till yesterday.
How can i inject the 600 ohm test signal? i mean, since the mic needs to be connected (in order to test amplifier response) i need to inject signal from pin 6 on the tuchel inside the PSU?
Should i keep the head assembly connected?
I would also perform some voltages test on PSU, can you suggest me a proper dummy load and where it should be connected?
Thanks everybody,
cheers
