[. . . ] 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. [. . . ] In some cases, the fundamental components may be so time-shifted that they reach the listener's ear ahead of some or all of the harmonic components. This change in the phase and amplitude relationship on the harmonic and fundamental frequencies is technically called "envelope distortion. " The listener perceives this loss of sound integrity in the reproduced sound as "muddy" and "smeared. " In the extreme, it can become difficult to tell the difference between musical instruments, for example, an oboe and a clarinet. conducted extensive studies of numerous speaker systems over a ten year period. With this knowledge, it became possible to identify the characteristics of an ideal speaker and to distill the corrections necessary to return the fundamental and harmonic frequency structures to their correct order. While there are differences among various speaker designs in the magnitude of their correction, the overall pattern of correction needed is remarkably consistent. ProdUcT deScriPTion The BBE 482i is a dual channel, single rack space device for use in -l0dBu line level applications. For each channel there are one pair of Lo Contour and Process knobs plus a 5 segment LED output 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 yellow when the process is off. The Lo Contour controls are 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. aPPLicaTionS Music and P. a. Systems The BBE Sonic Maximizer is a welcome addition to any live sound P. A. POWER: This switch controls primary power to the BBE 482i. ThingS To reMeMBer The BBE 482i is designed to work with -l0dBu line levels. The BBE 482i drives load impedances down to 1K Ohm and supplies a maximum output level of +18dBu. Plugging a guitar or other high impedance device directly into the BBE 482i will not work properly as its input impedance is less than 50K ohms. 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. (Note: For all models, replace with 250VAC, . 2A slowblow type fuse. ) 3. OUTPUT: The output of the BBE 482i can be taken from the 1/4" Phone Jack or the RCA Jack. This allows both outputs to be used simultaneously, eliminating the need for a "Y" cord in the event multiple outputs are required. If both outputs are being used, a minimum of a 22k Ohm load per device is required. (The "load" is determined by the input impedance of the next subsequent component in the signal chain. ) The maximum output is rated at +18dBu. [. . . ] During this period, we will repair units free of charge providing that they are shipped prepaid to BBE Sound, Inc. , 5381 Production Drive, Huntington Beach, CA 92649. All charges related to non-UPS shipping, including customs clearance, will be billed. The warranty will be honored for the longer of either 90 days from the date of any service or the remainder of the original 5 Year factory warranty. The equipment has been electrically damaged by improper connection or attempted repair by the customer or a third party. [. . . ]
