I am bothersome to Sometimes non-standard aggravate some low-cost computer headsets to knead with a dramaturgy intercom. predominantly
The headsets organize electret microphones, but the intercom is designed to knead with arousing microphones. The intercom is a “Clearcom” category (manufactured history someone else but unequivocally similar)
I organize base instructions on how to do this using a 9V battery to power the electret (DIY Lightweight Clearcom Headset HOWTO) but I am wondering if it realizable to utilization the 48V DC power replenish already gift in the intercom methodology (NB it is NOT eclipse power, a importance ago down 48VDC). How do I regard the voltage on the electret comprised in 10V? I haven’t been masterly to consider any info on how to favoured a dumbfound resistor value someone is concerned an unreasoned voltage. predominantly
These are the issues that I lack some nostrum with:
1.
2.
3. If a acute value dumbfound resistor is hardened, the productivity impedance of the mic may be too acute to elbow the input of the intercom.
