Quick Start Guide to Sennheiser G4 wireless audio
What is wireless audio?
A wireless audio system consists of a mic, a small radio transmitter (Tx), and a small radio
receiver (Rx). When the mic’s plugged into the transmitter, and the transmitter and receiver are
both tuned to the same frequency, we can mic up something much further away than it would be
practical to run an XLR cable. With clear line of sight this can be a couple hundred feet–or
substantially less if there are obstacles such as walls or foliage.
Our wireless audio equipment is Sennheiser G4. We have some configured for use in
the field, and some for use in the studios. Field production wireless kits can be checked out from
the Production Office. Our studio wireless equipment is built into two rolling cases, one assigned
to Studio A and the other to Studio B.

In the field production kits, the body-pack transmitter (SK 500) and the camera-mount receiver
(EK 500) appear very similar. A closer look reveals that the body-pack transmitter has one plug
on top--an input, for lavalier mic--while the receiver has two plugs on top--AF OUT, that sends
mic level signal to a recording device, and a headphone plug.
