About Sennheiser SK 100 G4

Because of its robust construction, the SK 100 G4 Bodypack Transmitter is designed for daily use on stage and is compatible with evolution wireless G4 100 G4 systems. This compact bodypack transmitter is designed to work seamlessly with a corresponding receiver as part of a wireless RF transmission system, offering a wide range of UHF frequency ranges.

The transmitter operates within twelve distinct UHF frequency ranges, including 470 - 516 MHz, 516 - 558 MHz, 520 - 558 MHz, 566 - 608 MHz, 606 - 648 MHz, 626 - 668 MHz, 734 - 776 MHz, 780 - 822 MHz, 823 - 865 MHz, 806 - 810 MHz, 925 - 937.5 MHz, 1785 - 1800 MHz. Each range offers 1,680 transmission frequencies, tunable in precise 25 kHz steps, providing a wide array of options for clear, interference-free transmission.

The SK 100 G4 Bodypack Transmitter features 20 fixed frequency banks, each with up to 12 compatible frequency presets, and an additional user bank with up to 12 user-programmable frequencies. This allows for easy customization and adaptability to various performance environments.

The transmitter is equipped with a backlit LCD display, providing real-time information on the current frequency, frequency bank and channel number, AF level metering, transmission status, lock status, pilot tone transmission, muting function, and battery status. An auto-lock feature is included to prevent accidental changes to settings.

The transmitter parameters can be easily configured in the associated receiver's menu and synchronized with the transmitter via an integrated infrared interface, or directly programmed in the transmitter menu. The device also features a mute switch, which can be set to "AF on/off", "RF on/off", or "Disabled" via the user interface.

Incorporating the Sennheiser HDX compander system and a defeatable pilot tone squelch, the SK 100 G4 Bodypack Transmitter ensures high-quality audio transmission. The audio frequency response ranges from 80 - 18,000 Hz (microphone) or 25 - 18,000 Hz (line), with a signal-to-noise ratio at 1 mV and peak deviation of >= 110 dBA, and total harmonic distortion (THD) of <= 0.9%.

Power is supplied to the transmitter by two 1.5 V AA size batteries or by one Sennheiser BA 2015 rechargeable accupack, with a nominal voltage of 2.4 V for a rechargeable battery or 3 V for a battery. The current consumption is typically 180 mA at nominal voltage. The Sennheiser SK 100 G4 Bodypack Transmitter is a reliable and versatile choice for professional audio transmission needs.
