Introduction Congratulations on purchasing the Samson Concert 88 wireless system. The Concert 88 is the ideal solution for the active performer who needs a reliable, great sounding system for wireless applications. Featuring simple operation, with 16 available channels and infrared set for the transmitter channel, the Concert 88 can quickly be up and running out of the box. The Concert 88 system ensures clear, interruption-free performance by combining tone-key with auto-mute.
System Features • Professional wireless system for use in both live sound and sound contracting applications • True diversity technology maximizes active range (up to 300 feet) and reduces potential interference • 16 available channels operating in the UHF band designed for maximum system compatibility in the same location without interference • The CR88 receiver is a half-rack unit that can be used freestanding or can be mounted in any standard 19" rack using the included rack kit, making it easy to
Guided Tour - CR88 Receiver 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 CR88. 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.
Guided Tour - CR88 Receiver FREQ: 542-566MHz This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. 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.
Guided Tour - CB88 Belt Pack Transmitter 1. Input Connector - Connect the input device via the mini-XLR connector.

Quick Start - Single System Setup In order for your wireless system to work correctly, both the receiver and transmitter must be set to the same channel. Follow this basic procedure for setting up and using your Concert 88 wireless system: Physically place the CR88 receiver where it will be used, and extend the antennas vertically. The general rule of thumb is to maintain “line of sight” between the receiver and transmitter so that the person using or wearing the transmitter can see the receiver.

Quick Start - Single System Setup Press the SELECT button on the front of the CR88 receiver to choose an available channel. The channel number will increase by one digit, from 0-9 then A-F. Once the last channel has been reached, the count will cycle back to 0. FREQ: 542-566MHz This device complies with Part 15 of the FCC Rules.
Quick Start - Single System Setup When the transmission is complete, the CR88 will receive RF signal and the tone key from the transmitter. The READY indicator will light on the front panel of the CR88 receiver. Turn on your connected amplifier or mixer, but keep the volume all the way down. Set the Volume knob on the CR88 fully clockwise (to its “10” setting). This is unity gain.
Quick Start - Multiple System Setup When using multiple systems, each system must be set to a different operating channel. Transmitter and receiver pairs must be on the same channel plan in order to work together (See "Concert 88 Channel Plans" on page 20). 8. Press button on transmitter to turn on 9. Press and h When setting an additional transmitter, make sure to close all other transmitter battery compartments to ensure that the IR Lens is covered.
Quick Start - Multiple System Setup Position the transmitter about 6-12" (15-30 cm) from the front of the CR88 with the transmitter's IR window facing the receiver's IR transmitter. 3.
