High-performance XLR cable!
For more than 30 years, Whirlwind has been producing high-quality audio cables with musicians in mind. You can benefit from their experience on the stage or in the studio with their workhorse cable, the MC20. They come in 20-foot lengths, so you can route them wherever they are needed.
Balanced for clean audio
XLR cables are the most common format in your rig. You connect them to your microphones, patch them to the mixer or the snake, and run them out to powered speakers. The MC20 is a balanced XLR to XLR cable, designed to handle any of these duties while preventing unwanted interference from entering the signal path. Outfit your whole rig with these balanced cables for clean, noise-free music!
As with all their cables, MC20's are built to Whirlwind's exacting specifications, using only the finest components. The XLR connectors have excellent strain-relief to prevent damage no matter how many times you plug and unplug them. Whether your cables stay connected in the studio or you take them out on the road, you'll have years of trouble-free use. No more tedious hours spent looking for a short circuit.
Flexible and durable
On tour, cables come out of the van, get uncoiled for the show, then wrapped up again for the trip to the next venue. They get stepped on, twisted around mic stands, and tripped-over. All this wear can take its toll, leading to cracks, shorts, and ultimately, poor sound quality. Whirlwind uses a finely stranded 22-gauge wire for the MC20's center core, and a strong, supple jacket to ward off nicks and scrapes. Your cables will have the toughness and flexibility to stand up to heavy road abuse, no matter how long you're on tour. No one wants to hunt for a music store 20 minutes before the gig, so make sure your cables are reliable and ready to rock when you are.
Not too difficult
You need a mic (could be lavalier or wireless -- about $100)
a microphone pre-amplifier
a headphone amplifier (4 to 8 outputs)
and long cables to plug the listeners' headphones into the headphone amp.
i cannot think of a way to get wireless connectivity to multiple sets of listener headphones-- i imagine that the radio-frequency wireless headphones from radio shack will conflict, but have no experience with them.
