I have a vintage EV-1750 cardioid Electret Condenser microphone (with internal battery power) with a hardwired ⅛" TS plug. Output level is -43db at 1000Hz and 150 ohms unbalanced. How do I, or what do I need to use this mic with my iMac running OS 10.11.5? Thanks!
There exists something called
Griffin Technology iMic - The original USB Stereo Input and Output Audio Adapter
which came into my posession, and I did some reading about it while trying to determine an asking price for sale. These were absolutely necessary with older Macbook models, as the on-board sound hardware lacked ability to deal with mic inputs. You can probably get by with just a properly-matching adapter
1-- making sure your computer's needs get lined up with what the vintage mic is sending out-- then tweaking the levels on the computer. But this external USB device
2 is said to be "high quality" as re sound, and actually comprises "a sound card" itself, so it can make things easier & possibly more dynamically modular as far as your overall environment.
