BBE 262 SONIC MAXIMIZER possible to identify the characteristics of an ideal speaker and to distill. the corrections necessary to return the fundamental and harmonic. The BBE Process What It Is frequency structures to their correct order While there are differences. Loudspeakers have difficulty dealing with the electronic signals among various speaker designs in the. supplied by an amplifier These difficulties cause such major phase and magnitude of their correction the overall pattern of correction needed is. amplitude distortion that the sound reproduced by a speaker differs remarkably consistent. significantly from the sound produced by the original source The BBE process is so unique that 42 patents have been awarded by. In the past these problems proved unsolvable and were thus the U S Patent Office. delegated to a position of secondary importance in audio system design. However phase and amplitude integrity is essential to accurate sound. reproduction Research shows that the information which the listener. The BBE Process How It Works, translates into the recognizable characteristics of a live performance are The BBE Process imparts a pre determined phase correction to the. intimately tied into complex time and amplitude relationships between high frequencies where most harmonic information exists This is done. the fundamental and harmonic components of a given musical note or by breaking the signal into three sub bands or groups a LOs 20Hz. sound These relationships define a sound s sound 150Hz b MIDs 150Hz 1200Hz and c HIGHs 1200Hz 20kHz. When these complex relationships pass through a speaker the proper The low group is delayed about 2 5 ms milliseconds via a delay. order is lost The higher frequencies are delayed A lower frequency within the passive low pass filter The front panel LO. may reach the listener s ear first or perhaps simultaneously with that of CONTOUR control allows for either a flat response or a boost at 50Hz. a higher frequency In some cases the components may be so The mid range group is delayed only about 0 5ms and passes. time shifted that they reach the listener s ear ahead of some or all of through an active band pass filter while the high frequency group. the harmonic components is passed through a VCA Voltage Controlled Amplifier The high. This change in the phase and amplitude relationship on the harmonic group is used as a point of reference to make dynamic amplitude. and fundamental frequencies is technically called envelope distortion corrections to the high frequencies. The listener perceives this loss of sound integrity in the reproduced The RMS average loudness detectors continuously monitor both the. sound as muddy and smeared In the extreme it can become diffi mid range and high frequencies to compare the relative. cult to tell the difference between musical instruments for example an harmonic content levels of the two bands and apply the appropriate. oboe and a clarinet amount of control voltage to the VCA thereby determining the amount. BBE Sound Inc conducted extensive studies of numerous speaker of high frequency harmonic content present at the final output of the. systems over a ten year period With this knowledge it became BBE processor. 2 BBE 262 INSTALLATION INSTRUCTIONS,FRONT PANEL CONTROLS.
1 CHANNEL A LO CONTOUR CONTROL Each channel is equipped with a LO CONTOUR control This control is a low. frequency adjustment for the BBE 262 It provides a boost of 10dBu when turned to its maximum position clockwise at 50Hz. When turned to its minimum position counter clockwise the low frequency is flat. 2 CHANNEL A PROCESS CONTROL Each channel is equipped with a BBE PROCESS control The BBE Process gives the. user a more detailed perception of tonality added bite and an increase in clarity The low frequency range of the program material. will be tightened while the high end will be crystal clear without adding or creating any additional noise or harmonic distortion. When the knob is in its minimum position completely counter clockwise no process is taking effect Turning the knob clockwise. will introduce the BBE Process Adjust the knob to mix the desired amount of BBE Process to suit your taste The BBE Process. also has its own in out switch for comparison of the processed to unprocessed signal located on the front panel Experiment with the. process Use the BBE Process as an extension of the tone controls The BBE Process is not an effect but a sonic improvement To. start set the BBE PROCESS knob to its 12 o clock position then adjust accordingly. 3 CHANNEL B LO CONTOUR CONTROL Same as Channel A Lo Contour Control. 4 CHANNEL B PROCESS CONTROL Same as Channel A Process Control. 5 BBE FUNCTION This switch engages the BBE Process When depressed the IN position the indicator LED will illuminate. Green indicating that the BBE Process has been engaged When in the OUT position the indicator LED will illuminate RED. indicating that the BBE Process has been disengaged. BBE 262 INSTALLATION INSTRUCTIONS 3,REAR PANEL CONNECTIONS. 6 A C INLET This jack is for connecting the 12 VAC power source. 7 POWER SWITCH This push button switch applies AC power to the BBE 262 Sonic Maximizer and is used for turning the unit. on and off, 8 FOOTSWITCH INPUT This mono jack is for connecting any mono shorting footswitch Using the remote switching jack. defeats the front panel function switch and allows the selection of process on off via footswitch. 9 11 UNBALANCED OUTPUTS Each channel is equipped with a 1 4 phone jack Each output sends a low impedance line. level signal The recommended single load impedance is at least 10k Ohms The load is determined by the input impedance of the. next subsequent component in the signal chain The maximum output is rated at 17dBu The output impedance of the BBE 262 is. 1k ohm NOTE Actual output level will vary due to the selected position of the BBE Process and the actual input signal level. 10 12 UNBALANCED INPUTS Each channel is equipped with a 1 4 phone jack Input range can be any level from 45dBu to. 6dBu The input impedance of the BBE 262 is 50k ohms. 4 BBE 262 INSTALLATION INSTRUCTIONS,GENERAL OPERATION. THE BBE 262 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 262 OR ANY SUBSEQUENT. COMPONENT IN THE SYSTEM IN THE EVENT THE OUTPUT OF A POWER AMP IS CONNECTED DIRECTLY TO. THE BBE 262, 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 BBE 262 may be utilized in a number of different environments and its results may vary accordingly Because both channels are.
completely independent from each other only one channel of the BBE 262 may be used or each channel processing a different. signal source The effects loop is the ideal placement in the signal chain of a guitar application In a pre amp keyboard or P A. application the BBE 262 works best as the last component in the signal chain just before the crossover or power amp Important. In a P A application never connect the BBE 262 into the effects loop The inherent phase shift of the BBE Process will cause. phase cancellation resulting in a partial loss of signal. BBE 262 INSTALLATION INSTRUCTIONS 5,BBE AND EQUALIZATION. The most common question asked of the BBE Sound Inc service department is Where does the BBE Processor connect in the. signal chain before or after the equalizer Many people find that the same amount of equalization is no longer needed if at all. when a BBE processor is used Additionally the amount of equalization used will help determine the BBE 262 s proper location in. the signal chain If the EQ is being set to give the room a flat response as determined by a spectrum analyzer the BBE 262 will. work properly before or after the EQ Placing the BBE 262 after the EQ is recommended If the EQ is being used for drastic tone.
