I'm in the market for a wireless lavalier. I was burned in the past by selecting a cheap VHF frequency mic. I learned later that was a bonehead move because VHF is used for everything from TVs to garage door openers.
I'm now considering a Sennheiser that offers four variants for frequency band. Those are listed as:
- A - 516 to 558 MHz
- A1 - 470 to 516 MHz
- B - 626 to 668 MHz
- G - 566 to 608 MHz
I understand what wireless frequencies are and that interference is caused by using frequencies that are not wholly unused by others. What I don't understand is what I need to know to pick one of these. Are these all about equal, or is there one better than the others?
My use case is live conference events. I only plan to get one or two. This mic will be used all over the USA, mostly in major cities, but sometimes smaller cities, and almost always in a hotel or convention center.
These are some features of the mic that might affect this decision:
- 1680 Tunable Frequencies Across 42 MHz
- Auto Frequency Scan Finds Open Bands
- 3 Level Squelch To Block Interference
- 20 Banks With 12 Channel Presets Each
- Compander For Clearer Sound
- Auto-Lock Prevents Accidental Adjustment
