performance, new batteries are always recommended and encouraged. You should get
approximately 12-15 hours of battery life when using alkaline batteries. Rechargeable batteries
such as, NiCad and NiMH, have a much shorter usage time. Audix suggests having two sets
of rechargeable batteries and rotating them for each performance or set
8) When using a lavaliere microphone, the rule of placement to follow is to put the mic 6 inches
below the mouth, and centered. Unlike the TV station that has the mic placed at the reporter’s
navel, you have the challenge of working with live sound coming from the speakers in the
room. Placing the lavaliere too far from the mouth will lead to a low signal. Turning up the gain
to hear what is being said will dramatically increase the chance of feedback in your system. By
placing the mic in the proper position, you will also lessen the “racetrack” effect when the
speaker turns their head from side to side.
9) Audix also offers a headset microphone. To ensure best performance, make sure to position
the mic at the corner of the mouth. This will reduce the amount of “pops” that will happen when
the speaker pronounces words with plosives.
10) Do not set two transmitters to the same frequency – it will not work! At best you will cancel out
the signal; at worst your sound system will squeal loudly.
11) Both the handheld and Bodypack transmitters have an adjustable sensitivity setting of 0dB,
-6dB, -12dB, and -24dB. This is to give you the best gain before feedback, and also avoid
overloading your amp or mixer. Audix ships the RAD 360 systems at a -12dB position.
For a
particularly strong vocalist or speaker, it may be necessary to "pad" the mic to -30 dB. This
feature may also be useful in a particularly noisy environment.
12) The more wireless mics you use in an area, the more chance you have for interference
between the systems because of the additional frequencies. This doe not mean that you can-
not use multiple RAD-360 systems in one location. To the contrary, Audix designed the RAD
360 to be compatible with upwards of 12-16 wireless systems in one location. Contact your
Audix representative at 1-800-966-8261 to assist you in the determination of which frequencies
can best be used at the same time in your particular location.
