RI-65-30

RI-65-30 is an onboard matching amplifier designed to match the output of the RI-65-10 voice unit and aircraft radio equipment with the pilot’s headsets. The unit provides proper signal amplification and impedance matching to ensure clear and reliable voice annunciation for the flight crew.

The RI-65-30 matching amplifier is included in onboard voice message systems such as RI-65-B and is also used as part of the Almaz-UP aircraft voice warning equipment. It receives audio signals from voice generation units and radio systems and delivers amplified signals suitable for both high-impedance and low-impedance pilot telephones.

The amplifier operates in normal and emergency modes and is designed for stable operation under severe aviation environmental conditions. RI-65-30 ensures reliable voice message transmission during normal flight operations as well as during abnormal and emergency situations.

The unit is intended for installation on aircraft and helicopters equipped with onboard voice warning and annunciation systems.
