Setting Up and Using the
Concert Series System
Concert Series System
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 transmitter 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 CR77 receiver and CT7 or HT7 transmitter 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 CR77 receiver where it will be used (the general rule of thumb is to main-
tain “line of sight” between the receiver and transmitter so that the person using or wearing
the transmitter can see the receiver). An optional rack-mount kit (available from your Samson
dealer) allows the CR77 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 CT7 belt-pack or HT7 handheld transmitter is set to
“Off.”
4a. If your system contains a CT7 belt-pack transmitter, push in both sides of the battery cover
and pull back to open the battery door, which is hinged and not intended to be removed from
the transmitter case. Please use care when opening this door as undue force will destroy the
hinge.
4b. If your system contains a 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. If you are using a CT7 belt-pack transmitter, gently replace the battery
door by swinging it up and pressing until it clicks. If you are using a HT7 handheld transmitter,
replace the bottom section of the microphone by sliding it on and then screwing it back on.
Whichever transmitter you are using, leave it off for the moment.
6. Make the physical cable connection between the CR77 output jack and the line or mic level
audio input of your amplifier or mixer. If you are using the balanced XLR jack (preferable, since
it will deliver an electromagnetically cleaner signal), be sure to set the CR77 rear panel Audio
Output Level switch correctly. If required, both the balanced and unbalanced outputs can be
used simultaneously. Leave your amplifier (and/or mixer) off at this time.
7. Turn the Volume knob on the CR77 completely counterclockwise. Using the strain relief,
connect the supplied AC adapter to the DC Input on the rear panel of the CR77, then plug the
adapter into any standard AC outlet. Press the front panel Power switch to turn on the CR77; the
red “Power” LED will light up, but all other front panel LEDs will remain unlit.
8. Turn on the power to the CT7 or 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, either the
“A” or “B” green LED on the front panel of the CR77 will light (depending upon which antenna
is receiving the stronger signal). Also, one or more segments in the CR77 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 CR77 or changing the position of one or
both of its antennas. If all six segments light, the CR77 is receiving an optimally strong RF signal
and is placed and positioned correctly.
9. Now it’s time to set the audio levels. Turn on your connected amplifier and/or mixer but keep
its volume all the way down. Next, make sure that your transmitter is unmuted by setting its
Audio switch to “On.” Then set the Volume knob on the CR77 fully clockwise (to its “10” setting);
