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 CH88 handheld transmitter features the Samson Q7 dynamic microphone capsule. This microphone offers extended dynamic range and excellent transient response, and the super-cardioid pickup pattern provides excellent off-axis rejection, minimizing ambient noise and reducing feedback. Enjoy up to eight hours of continuous operation with 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 CH88 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.
