Setting Up and Using the Concert IV System
The basic procedure for setting up and using your Concert IV VHF Wireless System takes only a few
minutes:
1. For the Concert IV 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 enclosed receiver and transmitter are set to the same channel (this is listed on the front
panel of the CR4 and CRND, on the belt clip of the CT4L and CT4G, and on the bottom of the HT4. If
these channels do not match, contact Samson Technical Support at 1-800-372-6766.
2. Mount the supplied antennas into your receiver (the CR4 has two antennas while the CRND has one)
by inserting the M connector and turning the outer ring clockwise until snug. Start by placing one or both
antennas in a vertical position; this will suffice for most environments. Insert the included Allen wrench
into the front of each antenna and turn clockwise to lock it into position.
3. Set the Power on-off switch in your CT4L / CT4G beltpack or HT4 handheld transmitter to “Off.”
4. If you are using a CT4L or CT4G transmitter, locate the Open arrow on the rear of its battery door and
press down and forward (away from the belt clip), then lift up. The battery door 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. If you are using an HT4 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 CT4L or CT4G transmitter, replace the battery door by swinging it down so
that it is parallel with the rear panel and then gently pushing upward towards the belt clip. Whichever
transmitter you are using, leave it switched off for the moment.
6. Make the physical cable connection between the output of your receiver (if you have a CR4, you can
use either or both of the balanced or unbalanced jacks) and the microphone level input of your amplifier
or mixer. If you have a CR4 and are using professional (-30 dBm) equipment, the balanced jack is
preferable since it will deliver an electromagnetically cleaner signal. Leave the amplifier (and/or mixer) off
at this time.
7. Turn the Volume knob on the front panel of the receiver completely counterclockwise (to the “0”
position). Connect the supplied AC adapter to the DC Input on the receiver’s rear panel, using the plug
lock, then plug the adapter into any standard AC outlet. If you have a CR4, press the front-panel power
switch to turn the unit on. Note that the Samson CR4 / CRND AC adapter is available with three different
plug types so it can be used in the United States, United Kingdom, or other European countries.
8. Turn on the power to the CT4L, CT4G or HT4 transmitter (using its Power on-off switch); the “Battery”
LED should briefly light if the battery is good. If you are using an HT4 transmitter, replace the bottom
section of the microphone by sliding it on and then screwing it back on. Once the transmitter is powered
on, either the “TX ON” LED (in the CRND) or either the “A” or “B” LED on the CR4 front panel will light
(showing which antenna is receiving the stronger signal).
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, as follows:
