Sennheiser Ew 100 G4-945-S (516 - 558 MHZ)

A configuration designed for the stage in the spirit of the "100" wireless systems

This wireless vocal set revolves around the SKM 100 G4-S handheld transmitter and the EM 100 G4 receiver, a combination designed to meet the needs of live performances and events where reliability, vocal clarity, and quick setup matter. The rack-mountable EM 100 G4 receiver, paired with the included GA3 rack kit, integrates easily into a control room, flight case, or stage rack to maintain a clean and stable setup from one concert to another.

The inclusion of the MMD 945-1 capsule clearly emphasizes vocal performance: it aims for focused capture, good control of the sound environment, and a mix-ready output at the console without requiring extensive corrections.

Who is it for and what are the uses?

This system is tailored for singers, choristers, hosts, speakers, and technicians who need a simple-to-deploy handheld wireless microphone with consistent sound quality. The supercardioid pattern of the MMD 945-1 capsule is especially relevant on stages where you want to keep the voice front and center while reducing pickup of side sounds (monitors, backline, room ambiance).

In event contexts, the mute button on the SKM 100 G4-S transmitter provides real control benefits: you can mute the microphone between interventions, during movement, or when passing the mic, helping to maintain a clean mix and avoid unwanted noise.

Supercardioid capsule and rack integration: a set focused on efficiency

MMD 945-1: precise and better-isolated voice

The MMD 945-1 microphone capsule (dynamic, supercardioid) is designed to deliver a direct and stable vocal capture with improved separation from surrounding sources. On stage, this facilitates sound engineering: the voice comes through more naturally, allowing you to seek presence without immediately fighting room ambiance or feedback.

SKM 100 G4-S: handheld microphone with mute for instant control

The SKM 100 G4-S handheld transmitter stands out here with its mute button, particularly useful for performances involving consecutive speaking parts, stage changes, or talk moments. This detail saves time and prevents many unforeseen issues, benefiting both the artist and the sound crew.

EM 100 G4: rack-mountable receiver for clean setups

The EM 100 G4 receiver is rack-mountable and comes with the GA3 kit, allowing easy integration into fixed or mobile installations. The result: clearer cabling, better-protected equipment, and a more coherent configuration when managing multiple audio components within the same rack.

The set also includes an RJ10 link cable and a microphone clip, covering essential connection and mounting needs right from the start, without requiring immediate additional purchases for common uses.
