  HT-3 HEADSET TESTER 

THE HT-3 IS ONE OF THE BEST, IF NOT THE BEST TESTER FOR HIGH IMPEDANCE HEADSETS, HEADPHONES AND MIKES.

THE HT-3 IS A MICROPROCESSOR-BASED HEADSET TESTER

THAT CAN TEST NON MILITARY:

FIXED WING HEADSETS

HELICOPTER HEADSETS 

GROUND MECHANIC HEADSETS

WIRED GROUND CREW HEADSETS

WIRELESS GROUND CREW HEADSETS

WIRED AIRCRAFT PUSH BACK HEADSETS

BLUETOOTH AIRCRAFT PUSH BACK HEADSETS 

AUXILIARY MIKES

HIGH IMPEDANCE HEADPHONES

HEADSETS AND MICROPHONES EXTENSION WIRES

The HT-3 is hands free and fully autonomous; it does not need, as other testers do, a headset in perfect condition to check other headsets or microphones. 

Not having to keep depressed any switch to activate the tester gives the advantage of using both hands to find momentary interruptions in the wiring.

In case of distortion the HT-3 can quickly determine if the distortion is generated in the headphones side  or the mike side of the headset.

The HT-3  has a Vu-meter calibrated to indicate 0 dB when the level of the standard microphone signal used to adjust modulation in COMM radios, is applied. In the Sound Pressure Level (SPL) test mode, the indication of the vu-meter is used to measure the sensitivity of the microphone and compare it with other of the same type. 

The HT-3 can test headsets f.e. SENNHEISER HME100, PELTOR 8006,8003, and others high impedance aviation headsets made by  BOSE , DAVID CLARK , TELEX , SENNHEISER , LIGHTSPEED , CLARITY ALOFT, SIGTRONICS , PILOT AVIATION  etc.

 

Features:

• Test microphones sensitivity using the SPL-TEST mode.

• Test microphones fidelity by amplifying its output, under normal speech conditions, and applying the signal to the phones or the front   panel speaker.

• Test headphones using an external microphone or an internal1Khz sinusoidal tone.

• Test mono and stereo headphones, PTT switches and extension wires.

• It is powered by a 9V battery and has a battery alert when the battery is low.
