Note: Antenna is not included. Please use the antenna that shipped with the PSM transmitters or other antenna from the appropriate frequency range.

Front and Rear Panels

① RF Output Antenna Connector	Use the ¼ wave antenna supplied with the P3T transmitter, or any other Shure antennas that cover 470-865 MHz
② RF LED Indicators	Green : RF signal present Red: RF signal overload
③ Power LED	Green : Power on Green/red flashing: Power output overload
④ Power Switch
⑤ Power Input	Requires a Shure PS60 power supply
⑥ Power Output	Requires a Shure PS411-PC power distribution cable to deliver power to transmitters
⑦ RF Inputs	Connect to transmitter RF outputs

Power and RF Connections

Connect the Shure PS60 power supply to a power outlet and to the power input on the PA411.
Connect the 1-to-4 power cable to the DC power output on the PA411.
Connect a power terminal from the 1-to-4 power cable to each P3T transmitter power input.
Connect an antenna to the P3T antenna output on the front panel. Acceptable antennas include the ¼-wave antenna supplied with the P3T transmitter or any Shure antennas that cover 470-865 MHz.
Connect each P3T antenna output to an antenna input on the PA411, using BNC coaxial cable.

LICENSING INFORMATION

Licensing: A ministerial license to operate this equipment may be required in certain areas. Consult your national authority for possible requirements. Changes or modifications not expressly approved by Shure Incorporated could void your authority to operate the equipment. Licensing of Shure wireless microphone equipment is the user’s responsibility, and licensability depends on the user’s classification and application, and on the selected frequency. Shure strongly urges the user to contact the appropriate telecommunications authority concerning proper licensing, and before choosing and ordering frequencies.

This device contains licence-exempt transmitter(s)/receiver(s) that comply with Innovation, Science and Economic Development Canada’s licence-exempt RSS(s). Operation is subject to the following two conditions:

This device may not cause interference.
This device must accept any interference, including interference that may cause undesired operation of the device.

L’émetteur/récepteur exempt de licence contenu dans le présent appareil est conforme aux CNR d’Innovation, Sciences et Développement économique Canada applicables aux appareils radio exempts de licence. L’exploitation est autorisée aux deux conditions suivantes :

L’appareil ne doit pas produire de brouillage;
L’appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d’en compromettre le fonctionnement.

Federal Communications Commission RF Exposure Notice:

Antennas used for the purpose of radiating signals are limited to a maximum gain of 14 dBi. Each antenna must be positioned to observe minimum separation requirements from all users and bystanders. The following guidelines should be used when considering separation distances.

Antennas must be placed such that, under normal conditions, personnel cannot come within 72 cm (~2.5 ft.) from any antenna. Adhering to this minimum separation will ensure that the employee or bystander cannot exceed RF exposures beyond the maximum permissible limit as defined by 47 CFR 1.1310, i.e., limits for General Population/Uncontrolled Exposure.
