Related Questions and Answers

Q: 1. Do these work with the paddle antennas to get more range or help with interference?

A: No, the Shure BLX88 receiver included with the Shure BLX188/CVL Dual-Channel Wireless Cardioid Lavalier Microphone System has built-in internal antennas and is not able to connect to external antennas. For this option, you will want to consider using the Shure BLX4R, SLX-D, QLX-D, and ULX-D series receivers.

Q: 2. Can you replace the cardioid mics with omni directional mics?

A: Yes, there are many omnidirectional replacement lavaliers compatible for use with the Shure BLX188/CVL Dual-Channel Wireless Cardioid Lavalier Microphone System. The microphones in this system are not currently able to be swapped pre-purchase, but additional mics could be added. The following link shows currently listed omnidirectional lavalier options from Shure, which is a small sampling of potentially compatible omni microphones: https://bhpho.to/3977fE5

Q: 3. Will this system be impacted by the recent re-allocation of portions of the the 600mhz frequency ranges to cell phone companies? Or is their use illegal?

A: The bandwidth referred to collectively as the 600 MHz band includes frequencies from 617 to 698 MHz. Since this product operates below this space, it will not be affected by the reallocation.

Q: 4. Is the 1/4' output labeled Instrument out a line level output?

A: The manual shows the 1/4 inch output as -13 dBV into a 100K ohm load. With consumer line level at -10 dBV it's close but not quite line level.

Q: 5. Does this set work without a mixer?

A: The wireless mic system can be plugged directly into a powered speaker, via the MIC level XLR output or the LINE level 1/4-inch output.

Q: 6. Are these Mics UHF?
