Impedance tester UB-HTT-001

for headsetfor microphone

Product Overview
The UB-HTT-001 Aviation Headset Test Box is designed for inspection and functional testing of aviation headsets used by commercial and general aviation pilots and ground support personnel. With an intuitive control panel and integrated audio test functions, it enables technicians to verify speaker and microphone performance and to detect common faults in maintenance and ground-station environments. It is intended to streamline headset inspection and troubleshooting workflows.

Key Features

• Broad compatibility with mainstream aviation headset types and connectors (David Clark, U-174, Bose dual-plug, five-pin, Telex, A20 series)
• Built-in audio signal source for rapid speaker checks
• Sidetone microphone monitoring with built-in speaker for microphone verification
• Adjustable volume control to accommodate different test levels and impedances
• Impedance support for testing headsets across multiple impedance ratings
• Integrated noise gate to reduce background noise during audio tests

Applications

• Inspection and routine maintenance of pilot headsets (commercial and general aviation)
• Ground support and avionics workshops for rapid fault isolation
• Pre-flight checks and equipment acceptance testing
• Compatibility testing for headset fleet management
