Headway “Limpet Duo” pictured above.These should be
less prone to feedback than Microphones
vii)
Passive Piezo Ceramic
- Under Saddle Fitting
viii)
Passive flexible “Piezo Film”
contact pickups or
Under Saddle Transducer pickups ( may be encased in
metal ) - Ultra High Impedance
ix)
Passive Magnetic Sound-hole Pickups
- Low to Mid
Impedance Normally fairly proof against feedback
x)
MEMS Microphones
include analogue output
versions of miniature mic's mainly utilised in the
manufacture of digital devices. Not unrelated to Electrets
they exhibit a generally flatter frequency response and
note: take out "which" run on very low voltages (typically
3v-5v) from their own power supplies.
MEMS are new to the analogue audio industry but carry/
hold a lot of potential to rival miniature Condenser
Microphones ( i.e. a smaller footprint, lower power
consumption, higher sensitivity, flatter response and less
expense)
xi) True
Condenser or Ribbon Microphones:
Run
optimally at 48v from EDB-2 H.E or most mixers via XLR
connections, they deliver high quality amplification only at
very low stage volume levels without problems
xii)
Electret Condenser Microphones
Run on low voltages via battery compartments or on low
Phantom Power Voltages usually between about 5v-11v,
their sound quality is normally considerably lower than
with True Condenser Mic's or MEMS, but may be
powered by EDM-1 H.E or EDB-2 H.E 11v Phantom to
stereo Jack Plugs. Check if Tip or Ring wiring is required
