Performance characteristics:

● The PAS preamplifier is a broadband universal type, which can be applied to most common types of sensors and acoustic emission acquisition cards from various manufacturers;
● The pre-amp gain has three options of 20/40/60dB;
● Two signal input methods, single-ended/differential;
● Two power supply modes are available: phantom power supply, which is carried and supplied by the signal line; or direct power supply from an external power supply.
● Built-in filter, the corresponding frequency is divided into 4 gears for selection;
● It has the ability to protect against electric shock and the ability to recover from blocking phenomenon;
● Automatic sensor test (AST) function, which can send out a test signal source to the sensor (in the case of phantom power supply);
● Metal shell, shielding electromagnetic interference, anti-shock.
