Description
RDL ST-HP3 - High-Pass Filter 300 Hz / 500 Hz
The RDL ST-HP3 is a passive high-pass filter designed to protect horn loudspeakers in public address systems from damage caused by low-frequency signals. It provides line-level audio filtering with two independent outputs: 300 Hz and 500 Hz high-pass filters. Both outputs can be used simultaneously, offering flexible system integration.
The input and outputs are balanced, with the option for unbalanced operation. The module operates at +4 dBu line level and provides steep low-frequency attenuation at 18 dB per octave. Thanks to RDL’s SupplyFlex™ power input configuration, the ST-HP3 can be powered from ground-referenced, floating, or bipolar 24 V DC sources.
