Anchor Microphone AOSPOW1465 Uni-directional Gold Plated Diaphragm Low noise High SNR Anti-jamming Electret Condenser Microphone Top categories
The low noise and low input bias current of the OPA1678 make the device an excellent choice for high impedance preamplifiers for piezo elements. This preamplifier circuit provides high input impedance for the piezo element but has low output impedance for driving long cable runs. The circuit ...
less noise and slightly smoother attack… due 7 discrete FET preamp’s with much higher input impedance than the original… easy exchange without soldering unscrew, unplug, cut 2 wires, insert, replug, play new back plate 3mm smoked plexi with logo and holes for adjustment… ...
