RDL ST-HP3

The ST‑HP3 is the ideal choice where line‑level audio filtering needs to be provided at the input of a power amplifier for protection of public address horns against damage from low frequencies.

The ST‑HP3 has one input and two filtered outputs: 300 Hz high pass and 500 Hz high pass. Both the input and output are balanced, and each may be wired unbalanced if required. The input accepts line‑level (+4 dBu nominal) audio. The module operates at unity gain (balanced input and output). The two outputs may be used simultaneously.

The ST‑HP3 features RDL's SupplyFlex power input configuration for operation directly from ground‑referenced, floating or bipolar 24 Vdc power.
