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. Remove all packing materials (save them in case of need for future
service) and check to make sure that the supplied CR277 receiver HT7 transmitters are set to the
same channel. If these channels do not match, contact your distributor or, if purchased in the
United States, Samson Technical Support at 1-800-372-6766.
2. Physically place the CR277 receiver where it will be used (the general rule of thumb is to
maintain “line of sight” between the receiver and transmitter so that the person using the
transmitter can see the receiver). An optional rack-mount kit (available from your Samson
dealer) allows the CR277 to be mounted in a standard 19" rack if desired. Extend both “A” and “B”
antennas and place both in a vertical position.
3. Make sure the Power on-off switch in your HT7 handheld transmitter is set to “Off.”
4. On each HT7 handheld transmitter, unscrew the bottom section of the microphone by turning
it counterclockwise and then slide it off.
5. Place a fresh 9-volt alkaline battery in the transmitter battery holder, taking care to observe
the polarity markings. Replace the bottom section of the microphone by sliding it on and then
screwing it back on. Leave the transmitters off for the moment.
6. Make the physical cable connection between the CR277 output jack and the line or mic level
audio input of your amplifier or mixer. The CR277 allows you to send a mixed signal of the two
microphones to a single output, or send the two microphones separately through individual
outputs. You can use the MIXED output to feed a single channel in your mixer. Set the CR277's
rear panel MIX OUT switch to "ON" and both microphone outputs will be sent to the OUTPUT
B/MIX OUT. If necessary, you can use the CR277 front panel Volume controls to set the balance
between the two microphone. You can also use the individual Channel A and Channel B OUTPUTS
to feed two separate channels on your mixer. Set the MIX OUT switch to "OFF". Leave your
amplifier (and/or mixer) off at this time.
7. Turn both of the Volume knobs on the CR277 completely counterclockwise. Using the strain
relief, connect the supplied AC adapter to the DC Input on the rear panel of the CR277, then plug
the adapter into any standard AC outlet. The front panel Power switch is integrated into the
Channel B Volume knob. Turn the Channel B Volume knob just until it clicks to turn on the CR277;
the red “Power” LED will light up, but all other front panel LEDs will remain unlit.
