Concert 88x Presentation

Pro Performance. Simple Setup.

Simplicity and performance are at the heart of the Concert 88x wireless systems. One-touch scanning analyzes all available channels and selects the clearest channel for your performance space. An infrared signal then locks the transmitter and receiver together on the selected channel. With 100 frequencies and a wide 25 MHz bandwidth, there are plenty of channels available for your event/application.

Sound Secure

The CB88 Beltpack Transmitter features a silent mute switch that eliminates popping noises when muting or unmuting the system, and an adjustable gain control for optimal performance. The CB88 fits securely on the performer's belt, waistband, or even in a pocket and provides up to eight hours of continuous operation from a pair of AA batteries.

Freedom to Roam the Stage

True-diversity design minimizes dropouts for loud, clear wireless reception up to 300 feet. Tone key and auto-mute circuitry ensures that only the audio signal from the CB88 beltpack transmitter reaches the receiver, and automatically mutes the system when the transmitter is out of range to prevent unwanted noise from entering the signal path.

Making Connections

The rear panel provides both balanced (XLR) and unbalanced (1/4") connections to an amplifier, sound system, or recording console. The half-rack format and included rackmount kit allow single or multiple CR88x receivers to be installed in a portable audio rack or fixed location.

Lavalier Microphone

The Samson LM5 Lavalier Microphone features an omnidirectional pickup pattern that provides excellent pickup even when the presenter's head is turned to the side-or when talking face-to-face with another person. Use the convenient clip to attach the microphone directly to a tie, lapel, fabric fold, etc.
