Use 16” wires for VHF or 3”-6” wires for UHF.

If so, either (1) repair the distribution amp, (2) install a new amp, or (3) connect antennas or stiff wires on the back of each receiver. Stand next to the receiver, then take the wireless mic all the way to onstage. To find out, turn on a wireless mic and check the RF signal level on its receiver. You want to see if the remote antenna system is working. There should be an RF signal splitter (RF distribution amp) connected between the antennas and the receivers.
To do that, you might need to mount the receivers up high on a platform.
A remote antenna (or two for diversity operation) is useful when you have several receivers in a rack that is far from the stage, and you want to put their common antenna closer to the actors to pick up a strong signal. Try to arrange the transmitter antenna so that it’s not tight against the body.įirst, note that receiver antennas can be connected directly to the back panel of the receiver, or they can be remote. You might put heatshrink tubing or surgical tubing over the transmitter antenna. If the body-pack transmitter uses the mic cable as the antenna wire, keep it as straight as possible.Keep the antenna and mic cables separated. Do not loop the body-pack antenna cable over itself or over the mic cable. If a body-pack transmitter has a separate antenna wire, keep it taut with a rubber band and safety pin clipped to clothing.Avoid channels 52 to 69 (700-800 MHz band) because those channels are no longer allocated for wireless mics.If two performers will be working close together, assign them frequencies that are as far apart as possible to prevent interference.If two mics must share the same channel, turn one mic off. Make sure that each mic is on its own channel, not shared with other channels.Put belt packs in condoms or sandwich bags to keep off sweat.Check that “static” sounds aren’t just clothing noise.Check battery voltage with a digital voltmeter and replace 9-volt batteries at about 8.5 volts or slightly lower. To minimize dropouts, try the suggestions in this checklist. Each wireless mic must have its own separate receiver, and each mic/receiver pair must be set to the same channel. The transmitter has an antenna and the receiver has one or two antennas. That happens because the mic’s radio signal was lost, either by a weak transmitted signal, a weak received signal, or interference with other radio waves.įortunately, there are many things you can do to prevent dropouts, and we’ll cover them here.įirst, remember that a wireless mic system has two parts: a transmitter connected to a microphone on stage, and a receiver that picks up the transmitted signal and feeds audio to your mixer. The microphone makes a burst of noise or cuts out. Chffffft! That’s the sound of a wireless mic dropout.
