SAS-SM8A Sonic Mushroom™ is a tabletop monitor speaker with built-in user source selector, source display, and volume adjustment. Source selection and volume adjustment are all electronic, using touch controls on the top of the mushroom. The SAS-SM8A disburses sound in three directions onto a table top. It is ideally installed on a small table surrounded by people such as those in sports clubs. Because the sound is localized to the table area, people at adjacent tables may clearly and audibly listen to different sources. The selector allows the users to pick one of eight possible sources, or no source (off). Volume may be ramped up or down. If system power is turned off, all SM8s in the system power up at minimum level.
