The Sennheiser EW100 G4 is a high-quality wireless microphone system used for professional audio recording and live performances. The system consists of a transmitter (such as a handheld microphone or a lavalier microphone) and a receiver. It is designed to deliver high-quality audio performance with reliability and flexibility.

The transmitter is responsible for capturing the audio input signal, such as voice or an instrument, while the receiver wirelessly receives it and sends it to an audio output that can be connected to a mixing console, speaker system, or recording equipment. The EW100 G4 uses high-quality UHF frequencies to ensure a stable and interference-free wireless connection.

This system offers advanced features such as frequency synchronization, adjustable transmit power levels, and a clear display for easy operation. It is suitable for professional applications such as live performances, audio recording for film and video, presentations, and conferences.

A Sennheiser EW100 G4 wireless microphone system works as follows:

Transmitter (Microphone): The system starts with the transmitter, which captures the audio source, such as voice or an instrument. This can be a handheld microphone that the user holds, a lavalier (lapel) microphone that attaches to clothing, or an instrument microphone, depending on the application.

Receiver: On the receiving end, we have the receiver. This is connected to a mixing console, speaker system, or recording equipment. The receiver wirelessly receives the signal from the transmitter.

Frequency Tuning: The system uses UHF frequencies for wireless communication. Both units must be tuned to the same frequency to communicate. This can be set manually or using automatic frequency synchronization.

Audio Output: The receiver sends the received audio signal to the desired audio output, such as a mixing console or speakers, amplifying or recording the sound.

Settings: The user can adjust various settings, such as transmit power, microphone sensitivity, and audio channel, depending on the application's needs.

This system enables wireless audio transmission, which is convenient for applications such as live performances, presentations, and recordings where wired microphones are impractical.

The difference between a Sennheiser XSW and a Sennheiser EW100 G4 system primarily lies in their performance, features, and applications:

Sennheiser XSW:

The XSW system is designed for basic needs and offers a more affordable option within Sennheiser's range of wireless microphone systems.

It generally has more limited frequency options and fewer advanced features compared to the EW100 G4 system.

XSW systems are suitable for general applications such as live performances, small events, and presentations where simplicity and cost-efficiency are important.

Sennheiser EW100 G4:

The EW100 G4 system is a high-quality wireless microphone system with advanced features and high performance.

It offers a wider range of configurations, frequency options, and advanced settings, making it suitable for professional use in various environments, including live performances, film and video production, presentations, and conferences.

EW100 G4 systems are known for their excellent sound quality, robust construction, and reliable wireless performance.

The fourth generation of evolution wireless makes professional wireless technology even more flexible, even simpler, even more secure. For musicians, filmmakers, speakers at conferences and in lecture halls: G4 is a system that simply grows with you.

The EW 300 G4 is probably the most flexible wireless microphone system available today – thanks to great sound, reliable wireless transmission and robust devices combined with the right accessories. You can rely on that – in any situation, in any application, in any location. The EW 300 G4 is suitable for all professional audio requirements and ideal for any speech, lecture, conference, presentation or live performance on a stage.

Renowned sound engineers worldwide rely on the versatility of the G4 500, especially when it comes to multichannel settings on the biggest stages. A bandwidth of max. 88 MHz, max. 32 channels. Includes Ethernet Connection for the Wireless Systems Manager (WSM) software - for the best frequency management in multi-channel installations.
