1. High gain antenna and magnetic preamplifier

2. Adaptive preamplifier for resonance tuning useful in a disk drive

3. The detector (10) is coupled to a preamplifier (100) characterized by the absence of positive feedback, and the preamplifier signal is communicated to a linear amplifier whose output signal is then digitized.

4. The Air tight ATC-3 is a high quality preamplifier with a great pedigree and remarkable sonics

5. According to # the microphone and preamplifier responses for measuring acoustic impulses within vehicles should meet the requirement illustrated in the graph below

6. In a magneto-optical storage device, a digitally adjustable preamplifier stage balances polarization signal levels through use of a digital compensation value.

7. According to SAE J247, the microphone and preamplifier responses for measuring acoustic impulses within vehicles should meet the requirement illustrated in the graph below.

8. An integrated Amplifier is two components in one — a power amp that drives your speakers and a preAmplifier for your music source components

9. The distance between the microphone's light source and its photodetector may be up to several kilometers without need for any preamplifier or another electrical device, making fiber optic microphones suitable for industrial and surveillance acoustic monitoring.
