MGT SS-27 — Stereo Stethoscope
MGT SS-27 is a professional stereo stethoscope built for discreet listen-through-walls operations. Using dual high-sensitivity sensors, it captures subtle vibration signatures through solid structures — including walls, ceilings, windows, doors and floors — to support confident monitoring and assessment in the field.
Two highly sensitive accelerometers pick up faint vibrations produced by sound waves within structures. The stereo amplifier enhances these signals for monitoring via headphones, while a line output can be used for recording workflows, depending on operational configuration.
- Stereo sensing via dual high-sensitivity accelerometers.
- Front-panel control for balance, volume and attenuation.
- Status indication with low-battery and voltage LED.
- Portable power via 4 × AA batteries.
- Compact form factor designed for practical deployments.
Highlights
- Optimised for discreet monitoring through a wide range of solid structures.
- Stereo operation supports improved interpretation and operator confidence.
- Compact, field-friendly design for rapid deployment.
