Front Panel Controls

1.SUB FREQUENCY: 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.

2.SUB LEVEL: This control adjusts the output level of the sub-woofer circuit. The level is adjustable from fully off to a gain of 6dB.

3.CLIP LED: Indicates when the output is 3dB below true clipping.

4.LED DISPLAY: The LED display is used to indicate the output signal level of the BBE 382isw. 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 monitors the input signal level. The Clip LED will illuminate at +17dBu, giving a 3dBu warning of the impending distortion at +20dBu, the actual clip point.

5.LO CONTOUR: Regulates the amount of phase corrected low frequencies.

6.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.

7.PROCESS: Regulates the amount of phase corrected high frequencies.

8.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.
