Need HELP converting Bogen MX30a pa into a preamp for recording


2013-05-08 8:36 am
I have a bogen mx30a in working order that I would like to use as a mic preamp for recording audio into my Akai DPS24 multitrack recorder.

I would eventually like separate outputs for each of the 4 mic inputs, but for now I just want to pass audio thru one of the mic inputs out to a channel on my board for vocal recording.

I have read to operate this old tube pa as a preamp to just pull the power tubes disengaging the output transformer. I have done so and the amp still turns on. (so far, so good)

Now, which termanls on the back of the amp do I use to go out to a channel on my dps24? (the dps24 takes both xlr and 1/4 in inputs)

general info and advice also appreciated

Thanks, dan
