NOOB BA and passive mixer questions
Posted: Sat Sep 28, 2013 8:48 pm
hello JLM people. I thought I would make this a general post:
I am about to make my first piece of audio gear, which is a simple 8 channel passive mixer feeding 2 mic pre's.
I am an electronics noob, though ok with a soldering iron.
I intend to use the Micro Passive Mixer kit then a couple of BA's for the final stage. (which I will improve on when funds are available.
I was going to make the units self contained the passive mix feeding internally into the pre's, but thought it would be nice to make them discreet, with discreet imputs.
So before I order parts, I have some Questions:
1. If supplying +48v phantom to xlr inputs for mics, do I need anything more than the BA, SMPS power supply, xlr ins and a dpdt toggle (phantom on/off)?
2. If I want an (input) gain pot, impedance pot and JLM34mm VU, do I need anything else apart from the suggested VU buffer (and of course the pots)?
My setup will be:
Micro Passive mixer > 2x BA with JML14 transformer, and NE5532AP opamp.
Finally, how does the micro passive mixer deal / sound with less than the full 8 channels used? (ie: using 4 channels sometimes)?
Thanks in advance. Your patience is appreciated!
Will.
