Samson Concert 88x Earset wireless system combines professional-grade audio with extreme ease-of-use. The system’s rack mountable CR88x receiver provides 100 wireless frequencies across a broad 25 MHz bandwidth and uses one-touch scanning to automatically select the clearest channel available in your performance space. The receiver’s True Diversity design minimizes dropouts while tone-key and auto-mute technology prevent undesired noise or interference when the transmitter is out of range. Concert 88x provides crystal clear audio and flawless wireless reception within a 300' range (line-of-site).The CR88x receiver is designed to easily integrate into nearly any amplifier, sound system or recording device, providing both balanced XLR and unbalanced 1/4” audio connections. The half-rack housing and included rackmount kit allow a single CR88x receiver – or multiple units – to be installed in a portable rack or at a permanent venue.The CB88 beltpack transmitter has a silent mute switch, which prevents popping noise when muting or unmuting the system and adjustable gain control for optimal performance. The CB88 fits securely on the performer’s belt, waistband, or even in a pocket, while delivering up to eight hours of continuous operation from a pair of AA batteries. The system includes the Samson SE10 low profile, miniature earset microphone with 3mm capsule. This discreet microphone delivers superior audio in a lightweight and comfortable package. The omnidirectional pickup pattern results in a clear and articulate sound, regardless of the position of the capsule.
