The SA-U24BP bodypack transmitter extends your existing 1st generation Seismic Audio wireless microphone system with hands-free capability for lavalier and headset mics. This replacement transmitter pairs exclusively with first-generation Seismic Audio wireless receivers and provides reliable UHF transmission for presenters, performers, and speakers who need mobility without cables.

Operating in the UHF 640-690 MHz frequency range with PLL phase-locked synthesis, the SA-U24BP delivers stable wireless transmission up to 400 feet. The built-in LCD display shows your selected frequency and battery status, while a red LED indicator confirms the unit is powered and transmitting. Frequency response spans 40Hz-15KHz, handling both spoken word and vocal performance applications effectively.

The compact bodypack measures just 3.75" x 2.25" x 1" and weighs only 0.15 pounds, making it comfortable for extended wear during presentations, worship services, or theatrical performances. Two AA batteries provide approximately 8 hours of continuous operation. The mini-XLR input accepts Seismic Audio lavalier and headset microphones, while the included belt clip ensures secure attachment during active use.

Setup requires pairing the transmitter with your existing Seismic Audio wireless receiver and connecting a compatible lavalier or headset microphone to the mini-XLR jack. The transmitter, belt clip, and user manual are included—batteries and microphones sold separately.

Backed by Seismic Audio's one-year warranty and fast shipping, the SA-U24BP provides dependable wireless expansion for houses of worship, conference rooms, and small venues up to 400 feet in range.

How long do the batteries last and what type do I need?

The bodypack operates on two AA batteries (not included) and provides approximately 8 hours of continuous use. The LCD display includes a battery level indicator so you can monitor power status during use.
