Highlights
- Treble, mid, and bass sections with dedicated filter settings.
- 12 dB/octave slopes and a 24 dB/octave subsonic filter.
- Rated total harmonic distortion of less than 0.02%.
- Channel separation greater than 80 dB.
- Selectable subsonic filter at 20, 30, or 40 Hz, or flat response.
- Rated bass boost from 0 to +12 dB.
Description
The STETSOM STX84 provides analog signal processing before the amplifiers. Its active filters allow you to distribute the frequency bands among the different channels of an installation and adapt the signal to the speakers used. The 0° or 180° phase selection helps manage electrical coherence between the channels; it is not a time delay setting.
With a maximum output voltage of 9 V RMS and a signal-to-noise ratio greater than 90 dB, this filter is designed for low-noise, low-distortion signal transmission. Available from Sound Auto Concept, the STX84 is intended for multi-amplified car audio projects as well as professional applications with a compatible 10 to 16 V DC power supply.
- Analog processor and active filter, with no rated speaker amplification power.
- Maximum input voltage of 4 V RMS, to be observed when setting the source.
- Subsonic filter designed to limit infrasound transmitted to the bass channel.
- Rated maximum current consumption of 0.25 A.
- Dimensions of 33 × 236 × 160 mm and a weight of 700 g.
