Microphone preamplifier ED 30 SMD

NF - Preamplifier for very small input voltages - for example from dynamic -, electret -, computer microphones or similar ...

A "strong" and well modulated transmit signal is easier, better and faster audible, increases the efficiency of the transceiver and creates a listening experience.

Technical data:

super flat: only  3,5 mm
super small: only  13 x 42 mm (W-D)
frequency range: 150 Hz - 10 kHz
operating voltage: 5 - 16V/DC
operating current:  ca. 1.5 mA
amplification: 5 mV - 5 V / 1 kOhm

Gain can be adjusted separately by two trimmers.
HF-protected, two-stage, DC-voltage for electret microphones

fixation by adhesive tape

At the input of the preamplifier, all microphones with an impedance of about 150 ohms to 50 ohms can be connected.
