With less than 3 ms latency, 32-bit encrypted digital modulation and operating range up to 300', the system delivers dependable low-noise audio performance even in crowded RF environments.

Handheld and Headset Flexibility for Live Performance

The three included HH48 handheld transmitters feature dynamic cardioid microphone capsules designed for focused vocal clarity and strong rejection of unwanted stage noise and feedback. Their LCD displays provide quick access to frequency, mute and battery status during live use. The included MBP48 bodypack transmitter paired with the HS13-UBK-GAL headset microphone adds a hands-free solution ideal for presenters, instructors, fitness applications, worship leaders and performers who require unrestricted movement on stage. The headset’s dual-ear wraparound design helps keep the microphone secure and comfortable during extended performances and active presentations.

The CSL4 receiver provides balanced XLR outputs for each channel plus a summed unbalanced 1/4" output for simplified integration into mixers and installed sound systems. Integrated 7-band EQ processing per channel allows quick tonal adjustments directly from the receiver, while customizable LCD display colors help visually organize channels during live operation. The system can also expand with optional Galaxy Audio accessories including lavalier microphones, antenna distribution systems and directional antennas for larger wireless installations and advanced RF management.
