Samson Airline 77 Wind Instrument AH1 HM40+CR77 E2 Product Details

Description

The Samson Airline 77 Headset System combines the new with the tried AH1/QV CR77 receiver, or AH1/QE- transmitter system to a now better-sounding belt pack-free wireless. All systems of the Airline 77 series broadcast in the the frequency band 863-865 MHz. There are 4 different frequencies available. Included is also the power supply AC500 and a sturdy carrying case.

AH1 Headset-transmitter Aerobic

The AH1 headset transmitter is mounted directly to Samson's comfortable and lightweight headset microphone Samson QE. Thus, the user has no annoying cables that go from the microphone to a belt pack transmitter and thus has the freedom of movement that is desired, especially in fitness or similar applications. The electret condenser mic capsule of Samson QE microphone is water resistant and has an eight as polar pattern. This, and the center-weighted frequency response of the microphone capsule QE is always optimum speech intelligibility, even if the user is prepared to move, guaranteed.

Despite its ultra-compact design, the AH1 transmitter is equipped with an easy-to-reach power on / off switch, a mute switch, and a multi-function LED, which fitted the operation and battery condition. A potentiometer allows to adjust the mic level in order to avoid distortions can.

CR77 True Diversity receiver

The new 9.5 "wide True diversity receiver with PLL frequency control is the heart of all new Airline 77 Wireless Systems. Robust, durable and with a crystal-clear sound. The UHF (Ultra High Frequency) transmission provides anytime, anywhere for clean frequencies without interference. Thanks to true diversity receiver technology also belong to the past dropouts. The two 5-segment LED meters allow any time optimal control of the audio and the send level.
