AMP U174 Downlead Cable

Fischer connector to U-174/U (NATO standard). Connects the AMP Connectorized headset to any NATO-wired PTT or intercom via the standard U-174/U plug. Available in Dynamic and Electret wiring variants and multiple cable lengths.

Specifications

Headset Connector	Fischer (AMP Connectorized)
Output Connector	U-174/U (NATO Standard)
Cable Lengths	21″, 30″, 60″

Mic Type	150 Ω dynamic (standard) or electret variant

Wiring Variants

The AMP boom mic is a 150 Ω dynamic element. The downlead cable passes this signal to the PTT. Most tactical PTTs expect a dynamic mic — choose the Dynamic variant unless your PTT specifically requires electret.

Variant	Use Case
Dynamic	Standard tactical PTTs (U-94, Constant Able, Ops-Core PTTs, most NATO PTTs)
Electret	ICS/intercom systems or PTTs that supply bias voltage for electret mics
