Wireless Operating Frequencies
Frequency Selection
Each transmitter/receiver system operates on a single factory-aligned, crystal-controlled frequency.
Available frequencies are shown in the chart on the following page.
Operating frequency is specified by a two- or three-character code, such as “T2” or “12L,” in
addition to the actual frequency in MHz. The frequency of each transmitter appears on a label on
the outside of the unit. The frequency of each receiver appears on a label on the back of the unit
and the frequency of each system appears on the outer carton. For future reference, please record
them in the space provided below.
Because most of these authorized frequencies are shared with TV broadcasting, frequency selec-
tion is largely dependent upon which TV broadcast channels are in operation
where the wireless
system is to be used.
RF Interference
If you encounter receiving interference (from other than an operating TV station), often it can be
eliminated by adjusting the receiver’s squelch control, as described on page 6.
Please note that wireless frequencies are shared with other radio services. According to Federal
Communications Commission regulations,“Wireless microphone operations are unprotected from
interference from other licensed operations within the band. If any interference is received by any
Government or non-Government operation, the wireless microphone must cease operation...”
If you need assistance with operation or frequency selection, please contact your dealer
or the A-T professional division.
Extensive wireless information also is available on the A-T Web site at www.audio-technica.com.
For future reference, please record your system information here (the serial numbers appear
inside the battery compartment of each transmitter, and on the bottom of each receiver):
