You now own a very unique signal processing device with no equal in the audio world. Whether you purchased the BBE 362XL for your home studio, P. A. , DJ system, or instrument rack, you will find the 362XL's rugged construction and careful electronic design a welcome addition to your sonic arsenal. Thank you for your purchase, and for the trust that you've placed in BBE. [. . . ] Both are balanced and the same point electronically. This allows both outputs to be used simultaneously, eliminating the need for a "Y" cord in the event multiple, balanced outputs are required. The recommended single load impedance is at least 10k Ohms. 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 +26dBu. Pin #2 is considered the hot or "+" signal. The output impedance of the BBE 362XL is 600 ohms. NOTE: Actual output level will vary due to the selected position of the BBE Process, and the actual input signal level. If both the XLR and Phone Jacks are being used, both must be either balanced or unbalanced. Otherwise a loss of signal level will occur. INPUT: The input of the BBE 362XL is a balanced connection. Although is can be either a TRS 1/4" stereo Phone Plug or an XLR Plug, it is recommended that only one input source be used. Both jacks are the same point electronically, however, due to the input/output impedance characteristics of most audio devices, a loss of signal may occur and/or damage to a component if both inputs are utilized. Pin #2 is considered the hot or "+" signal. The input impedance of th BBE 362XL is 10k Ohms. The maximum signal level is +26dBu. 3 Specifications Frequency Response, process mode:. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

General Operation THE BBE 362XL 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 362XL 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 362XL. In order to reduce the risk of damage to any equipment, properly connect all cables and power cables before turning on any components in the system. Most important of all, ALWAYS TURN ON THE POWER AMPLIFIER LAST TO AVOID DAMAGING THE SPEAKERS OR THE AMP. [. . . ] The output will be monitored at the corresponding channel marked as 1/4" phone jack TRS. You should read less than +26vdc With your DVM set to D. C. Reading should be -12vdc, (+/- 0. 8vdc). BBE PROCESS TEST: 1. Input a 5khz signal ~ -lOdBu into channel A [B] input. [. . . ]
