Introduction / System Features Congratulations on purchasing the Samson CR277 Dual Microphone Wireless System! The CR277 system is the perfect solution for any application requiring two, high quality, wireless microphones in a compact package. The system features the CR277 dual channel, diversity receiver including dual antennas, vivid RF meters and Peak indicators for each channel, plus individual and mixed balanced outputs jacks.
System Features Designed for use in both live sound and sound contracting applications, the Samson Concert Series Wireless System provides a high performance, cost effective solution, utilizing state-of-the-art technology in wireless communications. Main features include: • Six different available channels in three pairs, all operating in the less crowded UHF bandwidth, and all designed for simultaneous use.
Guided Tour - CR277 Front Panel 1: Antennas (Channels A and B) - The antenna mountings allow full rotation for optimum placement. In normal operation, both Antenna A (the antenna on the left) and Antenna B (the antenna on the right) should be placed in a vertical position. Both antennas can be folded inward for convenience when transporting the CR277. See the “Setting Up and Using the Concert Series System” section on page 6 in this manual for information about antenna installation and positioning.
Guided Tour - CR277 Rear Panel 1 2 4 3 5 6 CR277 1: MIX OUT switch - Sets the OUTPUT B balanced output to send either the combined signal for Channel A and B when the switch is in the "ON" position, or to just Channel B when in the "OFF" position. See the “Setting Up and Using the Concert Series System” section on page 6 in this manual for more information.
Guided Tour - HT7 1: 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. Because the carrier signal remains during muting, no “pop” or “thud” will be heard. Note that turning this off does not turn off the transmitter power—it is simply a way to temporarily mute the transmission of audio signal.
Setting Up and Using the Concert Series System * Be sure to mute the audio signal at your external mixer or amplifier before turning transmitter(s) power on or off, or an audible pop may result. The basic procedure for setting up and using your Concert Series Wireless System takes only a few minutes: 1. For the Concert Series system to work correctly, both the receiver and two transmitters must be set to the same channel.
Setting Up and Using the Concert Series System 8. Turn on the power to one of the HT7 transmitter (using its Power on-off switch); the green “HIGH” Battery strength LED will light if the battery is sufficiently strong. At this point, a few segments in the CR277 front panel RF Level meter should light; the more are lit, the stronger the RF signal. If only one or two segments light (indicating a relatively weak signal), try relocating the CR277 or changing the position of one or both of its antennas.
Setting Up and Using the Concert Series System 12. Temporarily turn down the level of your mixer/amplifier system and turn off the power to your transmitter, leaving the CR277 on. Then restore the previously set level of your mixer/amplifier. With the transmitter off, the receiver output should be totally silent—if it is, skip ahead to the next step. If it isn’t (that is, if you hear some noise), you may need to adjust the CR277 front panel Squelch control.
