The MGT SS-27 lets operators monitor conversations and activity through solid structures — walls, ceilings, windows, doors, even concrete floors— without leaving a trace.

Core Advantages:

- Dual high-sensitivity accelerometers
Capture the minute vibrations generated by voices, footsteps, and mechanical noises.

- Rugged piezoceramic sensors
Metal housings with anti-breakage, tear-proof cables ensure reliable field use.

- 60 dB dynamic gain
Integrated stereo amplifier boosts extremely faint signals for crystal-clear monitoring or recording.

- On-board filtering & gain controls
Fine-tune frequency cut-offs and amplification in real time for optimum intelligibility.

- Portable power options
Runs on four 1.5 V AA batteries—or via 9-12 V DC external supply—for maximum flexibility.

- Recording-ready
Stereo headphone output for live listening plus line-out for external audio recorders.

Engineered for law-enforcement, military, and counter-espionage teams, the SS-27 delivers dependable performance wherever covert acoustic intelligence is required.
