Sennheiser SK 100 G4-A Bodypack Transmitter

Description

Sennheiser SK 100 G4-A | Bodypack Transmitter

The Sennheiser SK 100 G4-A Bodypack Transmitter is a standalone transmitter for compatible analog Sennheiser evolution wireless G4 systems. This A-band transmitter operates exclusively from 516–558 MHz, so confirm that your receiver supports overlapping frequencies before ordering. It is not compatible with Sennheiser EW-D or EW-DX receivers, as these systems use digital transmission while the SK 100 G4-A is an analog transmitter.

Designed for lavalier microphones, headset microphones, and instrument applications, the SK 100 G4-A features a locking 3.5 mm input and infrared synchronization for quick setup with a compatible receiver. It supports up to 20 compatible channels, offers 42 MHz switching bandwidth, and provides 1,680 selectable frequencies for flexible frequency coordination.

The durable metal housing is suitable for live sound, theater, education, worship, rental, and presentation environments. It delivers up to 8 hours of operation using two AA batteries or a compatible BA 2015 rechargeable battery pack. Transmitter only: receiver, microphone, instrument cable, and charging accessories are not included.
