- Compatible with CM, KM and KB/KD impact sound sensors for professional listen-through-walls applications.
Highlights
- Crystal-clear stereo signal reproduction with minimal background noise.
- Channel-by-channel tuning for different sensors and operational environments.
- Continuously variable gain control with real-time clip indication.
- Stereo monitoring and parallel recording via dedicated NF outputs.
- Robust, compact format designed for field and laboratory deployment.
FAQ Quick answers
What is the MGT STV-2 designed for?
The MGT STV-2 is designed for contact microphones and impact sound sensors, boosting very weak signals while maintaining clarity through a low-noise signal path.
Can I adjust each channel separately?
Yes. Each channel can be controlled independently, allowing precise gain and filtering adjustments for different sensor positions or target signals.
How do I monitor the output?
The system provides a stereo 3.5 mm output suitable for monitoring and integration with recording equipment, depending on the operational configuration.
