The ST-HP3 is a miniature wall and surface mount dual high-pass filter from RDL, and 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 unit has one input and two filtered outputs, 300Hz high-pass and 500 Hz high-pass. Both the input and output are balanced but each may be wired unbalanced if required. The input accepts line-level audio and the module operates at unity gain (balanced input and output.) The two outputs may be used simultaneously.
Dual high-pass filters for horn loudspeaker protection
Low frequency attenuation below 300Hz and 500Hz
Line-level input and outputs
Filtering requires no field adjustment
