Take The Worry Out Of Wireless
The dual-channel, frequency-agile Concert 288 Presentation allows up to 10 systems per band (20 performers) to operate simultaneously (depending on your region). The Concert 288 Presentation gives both performers an impressive 300′ of wireless range between the transmitters and receiver, making the system ideal for large stages and crowd participation. To ensure interference-free performance, the Concert 288 Presentation features a true diversity design. In the event of a drop-out, the receiver’s tone button triggers an automatic mute function to eliminate any background noise until the signal is restored.
Perform in Pairs
The Concert 288 Presentation includes two CB288 beltpack transmitters, two LM5 lavalier microphones with locking connectors, and two HS5 headset microphones with locking connectors. These microphone options provide maximum versatility for any dual-user application, especially dynamic presentations and interview situations. The transmitters, which 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.
