Polycom Group 500 Real Time Steering Array Microphone System
Product Information
AM11 Real-time Steering Array Microphone System
The AM11 Real-time Steering Array Microphone System is a sophisticated microphone system that can detect the location of a sound source and steer the microphone’s beam angle automatically in real-time to capture the targeted sound more efficiently. The system is equipped with Audio Input 1, which can be used for external equipment. The audio from this input is mixed with the input on the Polycom microphone array input and sent to the far end. This input will be muted when the local mute is activated.
Product Usage Instructions
- Connect the AM11 Real-time Steering Array Microphone System to your audio equipment using Audio Input 1.
- Turn on your audio equipment and the AM11 Real-time Steering Array Microphone System.
- The system will automatically detect the location of the sound source and adjust the microphone’s beam angle accordingly.
- If you are using Audio Input 1 for external equipment, ensure that it is enabled and adjust the input level as necessary.
- If you need to mute the microphone, activate the local mute function. This will mute all inputs, including Audio Input 1.
- If you need more detailed settings for the AM11 Real-time Steering Array Microphone System, refer to the Operating Instructions provided with the system.

- For more detailed settings for AM1,, please refer AM1,0s Operating Instructions.
GENERAL INFORMATION OF AM-1
The AM1, Real1time Steering Array Microphone System is a sophisticated microphone system, capable of detecting a sound source location, and steering the microphone’s beam angle automatically in real1 time to capture the targeted sound more efficiently.
Key Features
- The microphone unit is equipped with 8 microphone elements able to achieve the line array effect with a narrow horizontal dispersion angle of 50 degrees.
- The unit is able to detect a sound source location and steer the microphone’s beam angle automatically in real1time to focus on the targeted sound source.
- Allows monitoring of the sound source tracking status and setting of detail parameters. It is also possible to change parameter settings via a browser, when using a PC.
- The unit has a simple mute function with a physical mute switch on the microphone unit or through the GUI. The mute switch function of the microphone unit can be disabled through a GUI setting.
- It is equipped with two outputs: adjustable analog audio output level, and AES/EBU digital audio output.
