 Product Description

Physical Acoustics’ 1222 preamplifier is a radiation hardened charge preamplifier that features an internally-selectable 40/60 dB gain, standard Physical Acoustics pluggable filters with bandwidths of 20-600 kHz, and built-in test signal and control. The 1222 is directly compatible with all Physical Acoustics systems using the single power/signal BNC connection. The 1222 is also nuclear radiation certified.

Charge preamplifiers like the 1222 do not suffer from distance/attenuation effects like voltage preamplifiers do. They maintain the signal amplitude regardless of the distance from the passive sensor to the preamplifier. This attribute makes the 1222 ideal for use in cases where there is a need for long lengths of sensor input cable.
