AMP Communication Headset — Fixed Downlead

Same 3D Hear-Through technology and hearing protection as the Connectorized AMP, with a permanently attached downlead cable connected to the left earcup. Choose Fixed Downlead when your team runs a single radio type and needs fewer points of failure in the field.

Fixed vs. Connectorized

Feature	Fixed Downlead	Connectorized
Downlead Connection	Permanently attached (left earcup)	Quick-release Fischer connectors (L, R, or both)
Radio Flexibility	Single radio type	Swap cables for different radios
Failure Points	Fewer — no connector to work loose	More versatile but adds a disconnect point
Available Terminations	U-174/U or Amphenol	Fischer (cable sold separately)

Hearing Protection

Configuration	NRR	SNR
Headset Only	22 dB	27 dB
With NFMI Earplugs	34 dB	41 dB

Key Features

3D Hear-Through (3DHT): Ear-simulator design reproduces ambient sounds with directional accuracy — eight scalable levels (+12 dB max). Auto-hibernates after 2 hours of inactivity.
Fail-Safe Communications: Batteries die → 3DHT powers off, but radio comms continue. You never lose the ability to transmit or receive.
Noise-Cancelling Boom Mic: Ambidextrous 150 Ω dynamic boom mic mounts to either earcup. Remove entirely for listen-only operation.
U-173/U Accessory Port: Accepts standard mask mics (SOTR, CBRN respirators) via U-173/U plug.
Mission Configurable: Headband or helmet-rail mounting. Nylon wire-frame headband fits under a helmet.
