Product Description The BBE 882 is a dual channel, single rack space device for use in +4dBu balanced line applications. Each of the two independent channels has a Lo Contour control, Process control and a 5 segment LED input level meter. A single function button switches the BBE process on or off in both channels, which is useful for comparing the processed sound to the unprocessed sound. An LED next to the function button glows green when the BBE process is on and red when the process is off.
