User manual BBE SOUND BMAXT

[. . . ] When these complex relationships pass through a speaker, the proper order is lost. A lower frequency may reach the listener's ear first or perhaps simultaneously with that of a higher frequency. 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. [. . . ] LEVEL: This is a "soft-knee" compressor using a photo-optical cell as it's attenuating element for controlling gain-reduction. The single-knob LEVEL control will lower the threshold at which gain reduction begins and increase the ratio of input vs. output, simultaneously, as it is rotated in the clockwise direction from "0" to "10". IN/OUT: When switched to the "IN" position, the compressor circuit will be engaged as indicated by the green LED. When the incoming signal reaches the threshold, determined by the position of the LEVEL control, the yellow LED indicates that compression is taking place. This switch is superceded by the use of the optional FS-BMAX footswitch. BBE Process 10. LO CONTOUR: This control is a low frequency adjustment for the BBE Process. It provides a boost of 10dBu when turned to its maximum position (clockwise) at 50Hz. When turned to its minimum position (counter-clockwise) it would be flat or no change. PROCESS: When the knob is in its minimum position, completely counterclockwise, no process is taking effect and the circuit is in its noise suppression mode. Adjust the knob to mix the desired amount of process to suit your taste. Generally a good place to start the BBE process is to set the knob to it's 12 o'clock position, then adjust accordingly. BBE IN/OUT: This switch engages the BBE Process as indicated by the green LED. When in the "OUT" position, the green LED will not illuminate, indicating that the BBE Process has been disengaged. This switch is superceded by the use of the optional FS-BMAX footswitch. Output 13. MASTER: This control simultaneously adjusts the signal level of both the Balanced and Unbalanced outputs. The green power switch will illuminate when the power switch is in the "ON" position. 4 REAR PANEL CONNECTIONS 1. U. S. , Canada & Japan models: . 5A, 250VAC fast-blow type All others: . 250A, 250VAC fast-blow type Footswitch 3. BBE: This jack allows remote in/out switching for the BBE Sonic Maximizer section of the BMAX-T. COMP: This jack allows remote in/out switching for the COMP section of the BMAX-T. GROUND LIFT: In the "up" position, use this switch to disable the ground pin of the XLR connector. This is a useful feature in eliminating a ground loop between the BMAX-T and any subsequent component in the signal chain. Output 6.
