Overview:

The Samson AirLine 77 UHF Headset System offers a true wireless experience with no beltpacks and no cables, allowing complete freedom of mobility. The system includes the AH1 headset transmitter, along with the CR77 receiver.

Components:

CR77 True Diversity Receiver

• The CR77 true-diversity half-rack UHF receiver is at the core of the system.
•  A synthesized PLL frequency control circuitry keeps the signal locked and true while dual tuned molded antennas with LEDs monitor the true-diversity operation.
• The CR77 features a front panel display with large multi-segment audio level and RF level LED meters, and a large rotary volume knob allows easy adjustment of audio output. Its rear panel features balanced XLR and unbalanced 1/4-inch outputs allowing flexible connection options.
•  Where two wireless systems are required, two CR77 receivers can be rackmounted together in a single-space rack adapter available as an additional accessory.
• With the Concert 77 Presentation System, advanced technology and total convenience combine to provide professional wireless performance wherever you need it.

The Samson CR77 Wireless Microphone Receiver is paired with a number of Samson transmitters, such as the Airline and Concert series. The true-diversity UHF receiver features 1/4" phone and XLR output connections. True-diversity reception and PLL synthesized tuning result in reliable reception without noise and artifacts. Additional features include dual antennas, XLR and 1/4" phone output connectors, RF level LED meters, and a large output volume control dial. 

• XLR and unbalanced 1/4-inch outputs with mic/line level output switch
• True diversity UHF wireless headset system with PLL frequency control
• CR77 receiver features multi-segment audio level and RF level LED meters, squelch and volume control
• AC adapter and 1/4-inch to 1/4-inch cable included 

With AirLine Wireless, you get complete wireless freedom that's good to go anywhere the music takes you.

CR77 Front Panel Features:

1.) Antennas ( A and B ) - The antenna mounting allow rotation for optimum placement.

2.) Volume Control - This knob sets the level of the audio signal being output through both the balanced and unbalanced output jacks on the rear panel.

3.) Audio Meter - This "ladder" display indicates the strength  of the incoming audio signal.

4.) Squelch Control - This control determines the maximum range of the CR77 before audio signal dropout.

5.) A/B AntennaLED'S - When signal is being received,one of these will be lit green,showing you whether the (left) "A" or (right) "B" antenna is currently being used.

6.) RF (Radio Frequency) Level meter - This "ladder" display indicates the strength of the incoming radio signal.

7.)  Power Switch - Use this to turn the CR77 power on or off.

CR77 Rear Panel Features:

1.) DC Input - Connect the supplied 12 volt 160mA power adapter here using the strain relief.

2.) Balanced Output* - Use this electronically balanced low impedance (600-Ohm) XLR jack when connecting the CR77 to professional (+4) audio equipment.

3.) Audio Output Level Switch - Sets the audio output level attenuation of the balanced output to -20 dBm (line level) or -40 dBm (mic level.)

4.) Unbalanced Output* - Use this unbalanced high impedance (5K Ohm) 1/4" jack when connecting the CR77 to consumer (-10) audio equipment.

AH1 Headset Transmitter

• The AirLine headset transmitters feature the Samson Qe Fitness and QV10e Vocal microphone elements.
•  The Qe and QV10e headsets were designed to go around the back of your head rather than over the top.
•  This allows the transmitter to be attached directly to the headband, out of the way and completely unobtrusive, while being comfortable and secure during performances or group fitness classes.

• Both the Qe and the QV10e are designed with unidirectional microphones and cardioid pickup patterns that reject feedback.
•  The Qe Fitness headset is ideal for group fitness instructors who need a durable headset that will remain in place despite repetitious movement.
•  The QV10e Vocal headset has a microphone element that's perfect for singers who need hands free performance.
• All of the AirLine transmitters operate on inexpensive and lightweight AAA batteries that offer 14 hours of operation on a single battery.

Features:

• XLR and unbalanced 1/4-inch outputs with mic/line level output switch
• Headset transmitter features power/battery LED, power switch and mute switch
• Headset condenser mic is sweat resistant and employs unidirectional cardioid pickup pattern for great sound
• True diversity UHF wireless headset systAem with PLL frequency control
• CR77 receiver features multi-segment audio level and RF level LED meters
• Squelch and volume control
• AC adapter and 1/4-inch to 1/4-inch cable included
