Electro-Voice BP-300-A – UHF (A-band 618–634 MHz) Bodypack Transmitter for R300 Receiver, without Microphone

The Electro-Voice BP-300-A is the bodypack transmitter for the R300 wireless system, designed for everyday use in events, education, worship, theater, and presentations. It operates on the A band (618–634 MHz) and pairs with the R300 receiver on the same band. It offers 32 preset channels and quick setup features such as ClearScan (automatic channel scanning) and IR EZsync for one-step channel transfer from receiver to transmitter.

Its compact and robust metal housing houses a backlit LCD display with channel/frequency, battery level and mute status , as well as an external ¼ wave antenna . It uses two AA batteries with a typical battery life of up to 14 hours and an RF power of 8 mW , balancing range and stability. The TA4F input accepts EV/Telex lavalier and headset microphones and features a LAV/INS gain switch to optimize the level with lavaliers, headsets or instruments (via optional cable).

Main features

• Band A (618–634 MHz) for R300 systems of the same band.

Frequently Asked Questions

• Does it include a microphone? No. It's just the transmitter ; use a compatible EV microphone with a TA4F connector (lavalier/headset).
• Which receiver does it work with? An R300 on the same A band (the transmitter and receiver must match the band and channel).
• How many simultaneous systems can I use? Up to 8 per band (32 channels available), depending on the RF environment and coordination.
• Can I use it with a guitar/instrument? Yes, using the optional R300GTRCBL cable and the LAV/INS setting indicated in the manual.
