Comfortable During Performances

The Samson Airline 77 Vocal System E4 headset transmitter features the Samson QV10e Vocal mic element. This headset is designed to go around the back of your head rather than over the top meaning the transmitter can be attached directly to the headband, out of the way and comfortable during performances.

Cardioid Pickup Pattern

The QV10E is also designed with a unidirectional mic and cardioid pickup pattern that rejects feedback. The QV10e Vocal headset is ideal for singers who need hands free live performance because of the specially designed microphone element. The transmitter offers 14 hours of operation on a single AAA battery so you don't need to worry about it giving out before you do!

UHF Receiver

This system contains the CR77 true-diversity half-rack UHF receiver which is designed to work flawlessly with all AirLine UHF transmitters. Featuring dual tuned, moulded antenna, a front panel display with large segment audio level and RF level LEDs and a large rotary volume knob that allows easy adjustment of audio output. The synthesized PLL frequency control circuitry keeps the signal locked and true whilst the LED meters monitor the system's operation. The rear panel features balanced XLR and unbalanced ¼ inch outputs allowing multiple connection options.

It is possible to rackmount two CR77s together in a single space rack adaptor.
