I bought these to do 16 wireless headset mics for a school musical. These were plugged into a 16 channel board for a one-time performance. No need for these anymore but someone out there may have good use for them. Perhaps connect amps to mixers, daisy chain powered speakers and subs, localized desktop mics, etc.
Gear It is the manufacture. Sturdy and good quality.
The phone number if not a cell phone so do not text. Just call like we used to do in the 90s.
Sorry, too busy to provide you with a fancy photo. Sigh.
