System Operating Frequencies

Frequency Selection

Each transmitter/receiver system operates on a single factory aligned, crystal-controlled frequency. Available frequencies are shown in the chart below.

Operating frequency is specified by a two character code,

such as “T2,” in addition to the actual frequency in MHz. The fre- quency of each transmitter appears on a label on the outside of the unit. The frequency of each receiver appears on a label on the rear panel 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.

RF Interference

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.
