Congratulations on purchasing the Samson Concert 88x wireless system. The Concert 88x
is the ideal solution for the active performer who needs a reliable, great sounding system for
wireless applications. Offering frequency-agile UHF operation, the CR88x receiver provides 100
available channels to secure reliable wireless performance. The receiver provides easy setup
with 1-touch scan that analyzes and selects the clearest operating channel and infrared set to
pair the transmitter with the receiver.
The Concert 88x system ensures clear, interruption-free performance by combining tone-key
with auto-mute. This configuration allows only the transmitter’s audio to pass through the
receiver, and mutes the output if there is any interference.
The Concert 88x comes in four configurations. The vocal handheld system includes the CH88
handheld transmitter and dynamic microphone capsule. The CB88 beltpack system can be
configured with either a headset microphone, lavalier microphone, or a 1/4" instrument cable.
For travel or permanent installation, the Concert 88x includes a standard 19" rackmount kit.
In these pages, you’ll find a detailed description of the features of the Concert 88x wireless
system, as well as a guided tour through its control panel, step-by-step instructions for its setup

Introduction

Concert 88x Wireless System 7
ENGLISHFRANÇAISDEUTSCHEESPAÑOLITALIANO
1. Antennas - The antenna mountings allow full rotation for optimum placement. In normal
operation, both antennas should be placed in a vertical position. Both antennas can be
folded inward for convenience when transporting the CR88x.
2. VOLUME Control - This knob sets the level of the audio signal being output through both the
balanced and unbalanced output jacks on the rear panel. Reference level is obtained when
the knob is turned fully clockwise (to its “10” setting).
3. READY Indicator - This indicator lights green when the CR88x is receiving RF signal and the
system is ready to use.
4. PEAK Indicator - This indicator lights red when the transmitted audio signal is overloaded.
5. LED Display - The two digit, 7-segment LED display shows the receiver’s current operating
channel.
6. IR Transmitter - During “IR SET” an infrared light is used to set the transmitter channel.
7. SCAN Button - Press this button for more than 2 seconds to enter scan mode, the display
will flash quickly. The receiver will scan through the 100 operating channels to find the
optimal channel for performance. Once the scan is complete, the CR88x will enter IR Set
mode and send the selected channel to the transmitter.
Press and hold the button for more than 10 seconds to enter IR set mode, the display will
flash slowly. This will send the receiver’s current selected channel to the transmitter.
8. POWER Switch - Use this to turn the CR88x power on and off.

1. DC Input - Connect the supplied power adapter here, using the strain relief as shown in the
illustration below. WARNING: Do not substitute any other kind of power adapter. Doing so
can cause severe damage to the CR88x and will void your warranty.
2. BALANCED OUTPUT - Use this electronically balanced low impedance (600 Ohm) XLR jack
when connecting the CR88x to professional (+4dBu) audio equipment. Pin wiring is as
follows: Pin 1 ground, Pin 2 high (hot), and Pin 3 low (cold).
3. UNBALANCED OUTPUT - Use this unbalanced high impedance (5K Ohm) 1/4" jack when
connecting the CR88x to consumer (-10dBV) audio equipment. Wiring is as follows: tip hot,
sleeve ground.
Using the strain relief: Gather up a loop of
wire and pass it through the strain relief,
then pass the adapter plug through the
loop in order to create a knot.

7. Input GAIN Control - This control adjusts the transmitter input sensitivity to work with
microphone and instruments inputs. For optimal performance, using the included
screwdriver, set the input GAIN control to where you see the CR88x PEAK indicator start to
light under high levels, then turn down slowly until the PEAK light stops lighting.
8. Battery Holder - Insert two standard AA (LR6) batteries here, being sure to observe the
plus and minus polarity markings shown. Although rechargeable Ni-Cad batteries can be
used, they do not supply adequate current for more than four hours. WARNING: Do not
insert the batteries backwards; doing so can cause severe damage to the CB88 and will
void your warranty.
9. IR Lens - This window is used to capture the infrared signal sent from the CR88x during the
IR SET to channelize the transmitter.
10. Screwdriver - Designed for use in adjusting the CB88 input GAIN control.
