Direct and reflected sounds reaching the listener s ear Spatial information is an important means of orientation because human hearing is also used to determine the position of a sound source In certain situations this capability can be very useful or even of vital importance The fact that we can actually hear the size of a room shows how strongly developed the human sense of hearing actually is Based on the reflectivity of a room we can also distinguish though we often don t know how the materials it consists of In large rooms with high tiled walls reverberation is generally very dense and needs some time to decay while a small room with many objects in it furniture carpets etc features very short reverberation often not even perceived as such Nevertheless this extremely short reverb does exist which is the reason why many designers of reverb devices such as our VIRTUALIZER PRO implement several basic reverb types and give them specific room names Itis quite natural for example that a reverb preset called Cathedral produces a long and highly dense reverb whilea Room program usually represents the acoustics of a room that is much smaller in size In addition to the capability of human hearing to determine the direction from where a sound phenomenon arrives we can also hear modulations of acoustic events Of importance in this context is the frequency of the modulated signals Frequency modulations below 100 Hz are virtually inaudibl

17. e However frequency 4 TECHNICAL BACKGROUND 21 VIRTUALIZER PRO DSP1024P modulations can clearly be heard when occurring in the midrange frequency band due to the sensitivity of human hearing The ear immediately detects changes in midrange frequencies while its sensitivity to frequency modulation in the extreme low end of the frequency spectrum is reduced Frequency modulation can also be used to produce wanted effects The popular chorus effect for instance is basically the sum of a variety of frequency modulations The original signal is slightly delayed in the chorus algorithm then added again and modulated by means of an oscillator Subsequently modulating frequencies of different pitch are applied to the original signal which produces the well known floating chorus sound Basically frequency modulation is the starting point for all kinds of chorus type effects by simply adding the delayed signal without modulating the original you can produce a delay effect Since chorus effects use very short delay times the resulting delay effect is not perceived as such However when you increase the delay time there is a clear gap between original and effect signals and delay becomes audible A highly intensive effect can be achieved by combining reverb delay programs with modulation effects F orthis reason the BEHRINGER VIRTUALIZER PRO also features multi effects programs combining reverb or delay with for example a chorus effect In addi

38. se note the following remarks on how to set signal levels correctly 3 1 Level setting Take care to set all levels properly on the VIRTUALIZER PRO Low levels deteriorate the dynamics of the music signal which results in a poor weak and noisy sound On the other hand excess levels overdriving the converters in the VIRTUALIZER PRO should also be avoided Digital distortion is unlike its analog counterpart very unpleasant to hear as itdoes not occur gradually but abruptly Use the input level meter of the VIRTUALIZER PRO to adjust the input signal so that the Clip LED flickers only rarely Make sure that it never lights up permanently 3 2 Using the VIRTUALIZER PRO in the aux bus By using the VIRTUALIZER PRO in an aux bus of your mixing console you can feed the channel signals of one several or even all console channels into the VIRTUALIZER PRO i e for each channel you can use the aux busses to separately determine the reverb levels of for instance various drum sounds while lots of reverb is applied to the snare drum the effect intensity could be reduced in the channels assigned to the tom toms To use the VIRTUALIZER PRO in the aux bus the unit must be wired as follows sensa AUX Send AUX Return BHBHBBBB 0000000 0000000 0000000 0000000 0000000 0000000 0000000 0000000 17 VIRTUALIZER PRO DSP1024P Connect the two Input phone jacks with the Aux Send output
