... The SSM2005 Circle Surround surround soundfield from any stereo source, including VCD, DVD, VCR, CD and FM stereo broadcasts. The SSM2005 is also compat- ible with encoded sources, such as Dolby ProLogic Surround encoded movies and music. External delays and noise reduction processors are not required for the surround channels. ...

... All equipment manufactured using any SSM2005 Circle Surround decoder must carry the Circle Surround logo on the front panel in a manner approved in writing by SRS Labs, Inc. or Valence Technology Ltd. If the Circle Surround logo is printed in users manuals, service manuals or advertisements, it must appear in a form approved in writing by SRS Labs, Inc ...

... ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the SSM2005 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality ...

... A 2.2 k resistor connects the microphone to the +6 V supply rail, providing proper biasing for an electret microphone. The SSM2402 is used as a clickless switch, connecting the center output to either the center out from the SSM2005 or the microphone. In Circle Surround mode, the control voltages to the SSM2402 connect the output from the SSM2005 to the center output ...
