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.  Also 

included are two HT7 handheld microphone transmitters fitted with the Samson Q7 

dynamic microphone element. The Q7 produces a robust and articulate sound thanks 

to its extended frequency response and its cardioid pick-up pattern greatly reduces 

the chance of feedback. With the CR277 system, you’ll have great sound quality 

with clear reception and the ability to walk freely around your venue. For live sound, 

karaoke, school, conferences, and Houses of Worship the CR277 is an ideal solution for 

dual channel wireless microphones providing outstanding performance and reliably.

Although this product is designed for easy operation, we suggest you first take some 

time to go through these pages so you can fully understand how we’ve implemented a 

number of unique features. Your wireless system consists of three components— two 

microphone transmitters and a dual channel receiver, which must be tuned to the 

same channels (that is, the same radio frequency) in order to operate correctly. 

The Samson Concert Series system you have purchased operates in the HDTV free UHF 

frequency range and contains a CR277 dual channel receiver and two of our HT7 hand-

held microphone transmitters with the Samson Q7 dynamic capsule.

In this manual, you’ll find a  detailed description of the features of the Concert 

Series Wireless system, as well as a guided tour through all components, step-by-

step instructions for setting up your system, wiring diagrams and tables, and full 

specifications.  If your Concert Series system was purchased in the United States, you’ll 

also find a warranty card enclosed—don’t forget to fill it out and mail it!  This will 

enable you to receive online technical support and will allow us to send you updated 

information about this and other Samson products in the future.  Also, be sure to 

check out our website (www.samsontech.com) for complete information about our full 
product line.

SPECIAL NOTE for U.S. purchasers: Should your Concert Series Wireless system ever 

require servicing, a Return Authorization number (RA) is necessary.  Without this 

number, the unit will not be accepted.  If your Concert SeriesWireless system was 

purchased in the United States, please call Samson at 1-800-372-6766 for a Return 

Authorization number prior to shipping your unit.  If possible, return the unit in its 

original carton and packing materials.  If your Concert Series Wireless system was 

purchased outside of the U. S., contact your local distributor for servicing information.

*  Your receiver and transmitter have been factory preset to utilize the same channel.  

A listing of the six available channels and their corresponding UHF frequencies can be 

found on page 10 of this manual.
