Nor1203 1/2″ förförstärkare
Översikt (eng)
The key components that determines the accuracy of a sound level meter is the measurement microphone and its associated preamplifier. The effectiveness of these components in converting the acoustic signal into an electrical analogue set the maximum accuracy that can be achieved by the ensuing signal processing. Norsonic have a carefully balanced range of measurement microphones to suite a range of applications that complement modern instrumentation yet maintain traditional values.
We offer a broad range of 1/2″ and 1/4″ microphone preamplifiers.
- Broad frequency response
- Low noise
- High input impedance
- Low output impedance for driving long microphones cable without any loss in performance.
- High dynamic range
