Overview

Best choice for your business, top of the class in education. The G4 300 Series uses the power of an increased switching bandwidth of up to 88 MHz. New frequency ranges allow to operate multi-channel setups with dozens of channels while securing reliable operation - despite digital dividend.
Moderators and presenters love working with G4. The aluminum housing of the handheld transmitter is not just robust but also lightweight for long speeches, whereas the noiseless mute switch ensures full control.

• Easy to use, fast setup time
• Integrated network port allows control, monitoring and setup via Sennheiser Control Cockpit and WSM Software
• Broad range of products and existing accessories (such as microphones) allows usage in any kind of environment
• Up to 88 MHz bandwidth, up to 32 channels
