The Audio Precision AUX-0025 Two Channel Low Pass Filter is a passive switching amplifier. Measurement filters are designed to be inserted between the device under test and an analyzer input, to reduce out-of-band switching signal components before measurement. 

The AUX-0025 is used for mMeasurement of switching amplifiers, and measurement of analog signals with high amounts of out-of-band noise.

Highlights of:

●Two channel, 20 Hz to 20 kHz passband

●Passive design for optimal performance

●Custom inductors designed for power handling and minimizing low-frequency distortion

●Flat response

●Small insertion loss

●Compatible with both balanced and unbalanced amplifiers and analyzers
