Introduction / System Features Congratulations on purchasing the Samson Concert Series UHF Wireless System! 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. Every wireless system consists of at least two components—a transmitter and a receiver, both of which must be tuned to the same channel (that is, the same radio frequency) in order to operate correctly.
System Features • The CR77 receiver is a half-rack unit that can be used freestanding or can be mounted in any standard 19" rack,* making it easy to integrate into any traveling or fixed installation audio system. It includes a pair of tuned antennas and provides both balanced and unbalanced outputs, line/mic output level switch and continuously adjustable Volume and Squelch controls, as well as an audio peak LED, dual antenna indicators, a six-segment Audio level meter and a six-segment RF level meter.

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.

WARNING: Do not substitute any other kind of power adapter; doing so can cause severe damage to the CR77 and will void your warranty.
Guided Tour - CT7L /CT1G 1 3 2 4 1: Input connector - The input device is connected here. The CT7 is supplied with either a lavalier or headset microphone or 1/4" jack cable (connected via a mini-XLR jack). 2: Power / Battery LED - This LED flashes once when the CT7 is first turned on and lights steadily red when there are less than 2 hours of battery power remaining, indicating that the battery needs to be changed.
Guided Tour - CT7L / CT7G 9 7 8 10 7: Audio Input Level control (trimpot) - This input sensitivity control has been factory preset to provide optimum level for the particular lavalier, headset or for optimum instrument level, so we recommend that this not be adjusted manually. If necessary, however, you can use the supplied plastic screwdriver (see #10 below) to raise or lower the CT7 input level.

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.
Setting Up and Using the 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.
Setting Up and Using the Concert Series System this is unity gain. If you are using the HT7 transmitter or if you are using the CT7 transmitter with a connected lavalier microphone or headset, speak or sing into the mic at a normal performance level while slowly raising the volume of your amplifier/mixer until the desired level is reached.
Setting Up and Using the Concert Series System 11. Conversely, if you hear a weak, noisy signal at the desired volume level, again make sure that the gain structure of your audio system is correctly set (consult the owners manual of your mixer and/or amplifier for details) and that the Volume control of the CR77 is fully clockwise (at its “10” setting).
