  • Take The Worry Out Of Wireless

    The dual-channel, frequency-agile Concert 288 All-In-One allows up to 10 systems per band (20 performers) to operate simultaneously (depending on region). The Concert 288 All-In-One gives both performers an impressive 300' range of wireless operation between the transmitters and receiver, making the system ideal for large stages and crowd participation. To ensure interference-free performance, the Concert 288 All-In-One features a true diversity design. If a drop out does occur, the receiver's tone key triggers an Auto Mute function to eliminate any background noise until the signal is restored.

  • Perform in Pairs

    The Concert 288 All-In-One includes a CH288 handheld transmitter with a Q6 dynamic microphone capsule and a CB288 beltpack transmitter. For use with the CB288, the system also includes an LM5 lavalier microphone and an HS5 headset microphone (both with locking connectors). These microphone options provide maximum versatility for any dual-user application, especially duo performances, as well as audience participation and interview situations. The transmitters, which can operate for up to eight hours on two AA batteries, have been meticulously engineered to provide the ultimate in sonic performance.

  • Dual-Channel Receiver

    With a user-friendly front panel, the CR288 wireless receiver makes system setup quick and easy. To help you find your optimal channel, the CR288 has two select buttons that automatically synchronize the receiver and transmitter channels via an infrared signal. The front panel also features a dual 7-segment LED to indicate operating channels, two volume controls, two tuned antennas, and Ready and Peak indicators for optimal functionality and monitoring. The rear of the receiver features two separate balanced XLR outputs for routing signals to two separate mixer channels, as well as a 1/4" unbalanced mix output that combines both signals into a single channel for direct connection to a PA speaker.
