The Trantec S4.04-B (S4.04–B–EB–GD5) is the same kit as the ever-popular S4.04-L but doesn’t come with any microphones. This makes it ideal for those of you who may already own a preferred Lapel Microphone or Headset Microphone. As with other variants in the S4.04 range, this system operates on CH70 frequencies and up to four system can run together.

The S4.04B kit still fits in the Trantec Carry Case for safe transportation and will still get 10 hours of use from a AA alkaline battery. Connection leads for amplifiers or mixers will need to be purchased separately. Audio output levels for the equipment are the same as stated for the S4.04L system.
