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

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.

The CT7 beltpack transmitter clips securely inside your jacket or on your belt, and features a three-segment battery indicator, separate power and audio on/off switches and adjustable AF level (audio gain). The CT7 also provides 12 hours of battery life on a single 9-volt battery.

The Samson CT7 belt-pack transmitter is designed for use with compatible Micro and Concert series wireless microphone systems. The rugged, light weight unit can accommodate lavaliers, head-worn microphones, and instrument cables. The Concert Series features specialized patented electronics that stabilize transmission, resulting in low noise and minimizing drop outs. The CT7 features separate power and audio on/off switches, adjustable AF level (audio gain), and 12-hours of battery life on a single 9-volt battery.

CT7 Front Panel Features:

1.) Input Connector- The input device is connected here.

2.) Power / Battery LED  - This LED flashes once when the CT7 is first turned on and lights steadily red when there are less than 2 hours of battery power remaining,indicating that the battery needs to be charged.

3.) Audio on-off Switch - When set to the "on" position,audio signal is transmitted.When set to the "off" position the audio signal is muted.

4.) Belt-clip - Use this clip to fasten the CT7 to a belt.

5.) Battery Cover Release - Push in both sides of the battery cover and pull back to open the CT7 battery cover.

6.) Antenna  - This permanently attached transmitter "stiff" antenna should be fully extended for normal operations.

7.) Audio Input level control (trimpot) - This input sensitivity control has been factory preset to provide optimum level for the particular lavalier,headset or for optimum instrument level

8.) Battery Holder - Insert a standard 9-vlt alakaline battery here.

9.) Power on-off switch - Use this turn the CT7 on or off.

10.) Plastic Screwdriver - Specially designed for use in adjusting the CT7 audio input level control
