[. . . ] AC Receptacle - Check to make sure that the AC receptacle holds the power cord plug firmly and securely. If the power cord plug is loose, contact your electrician to replace the defective and unsafe AC Foreign Objects - Be careful that foreign objects and liquids do not enter the enclosure through openings. Use a damp cloth for cleaning. SERVICE Unplug the appliance from the wall outlet and consult qualified service personnel when: · the power cord or the plug has been damaged. · the appliance does not appear to operate normally or exhibits a marked change in performance. [. . . ] Patent Office. PROdUCT dESCRIPTION The BBE 382isw is a Sonic Maximizer and sub-woofer filter network combined into one unit. The single rack space device is for use in -10dBu unbalanced level applications. There are two separate channels that share the same front panel Lo Contour control and Process control for ganged-stereo operation. 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. The Lo Contour control is for adjusting the level of phase corrected low frequencies in the program material. The Process control is for adjusting the level of phase corrected high frequencies in the program material. The SUB section consists of a FREQUENCY control and a LEVEL control. The phase corrected low frequency information from both channels is summed together and directed through an 18dB/octave filter network. The SUB FREQUENCY control adjusts this filter and has a selectable range from 30Hz to 120Hz. By simply adjusting the Frequency control you can set the filter's frequency point of the Sub-woofer circuit. For example, if you set the Frequency control to 40Hz - then only the information below 40Hz will be sent to the Sub-woofer Output jack. APPLICATIONS Music and P. A. Each number on the front panel corresponds to the output signal level, measured in decibels. Example: The "0" indicates a 0dBu signal level, "-6" refers to -6dBu, and so on. Once an input signal level has been established, increasing the BBE PROCESS and LO CONTOUR will increase the output signal and cause more LEDs to illuminate. The Clip LED will illuminate at +17dBu, giving a 3dBu warning of the impending distortion at +20dBu, the actual clip point. PROCESS SWITCH: This push button switch allows for quick comparison of processed with unprocessed sound. When the switch is pushed in, the process is on and the indicator LED is green. When the switch is out, the process is off and the indicator LED is red. POWER: This switch controls primary power to the BBE 382isw. The BBE Sonic Maximizer is a line level signal processor and is to be connected prior to the power amp in any audio system. Significant damage may be inflicted to the bbe sonic maximizer or any subsequent component in the system in the event the output of a power amp is connected directly to the input of the BBE Sonic Maximizer. 5 Rear Panel Connections 1. FUSE: Insert a flat blade screwdriver into the fuse holder located in the bottom portion of the AC Power Cord inlet. Carefully pry the fuse holder free from its compartment to access fuse.
