The Audio Precision AUX-0100 Eight Channel Low Pass Filter (formerly known as APx581), 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-0100 is used for mMeasurement of switching amplifiers, and measurement of analog signals with high amounts of out-of-band noise.
Highlights of the Audio Precision AUX-0100 (APx581), include:
- eight 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
