2. ROOM BOUNDARY COMPENSATION The room boundary filters are designed to compensate for the effect of placing a speaker very close to the room corners front wall side wall front wall floor front wall side wall floor as doing so causes the space into which the speaker radiates to be bisected thereby directing more of the low frequency information into what we would call the direct sound The included filters compensate for such loading by removing the energy that would not normally be forced by the room surfaces into the direct response PRO loudspeakers are designed to be mounted into a wall surface with the neighboring surfaces adjacent room walls floor ceiling sufficently far enough away as to not materially effect low fre quency reponse We ll refer to this condition as 1 surface loading It is also sometimes referred to as 2pi loading Please refer to the illustration on the following page COMPENSATION FILTERS 24 Nas PMA AMPLIFIER SERIES PROAUDIOTECHNOLOGY side 1 SURFACE LOADING In this case the speaker is suf ficiently far away enough 4 or greater from room side wall and D floor to be considered 1 Surface i loading lt 4 min side D 4 floor 1 SURFACE NO COMPENSATION NECESSARY When the speaker is placed closer than approximately 4 to an adjacent surface i e side wall or floor the low frequencies will be boosted PMA

5. AUDIOTECHNOLOGY Set Reguired Compensation Filter if reguired Each channel of the PMA amplifier can be programmed to apply a compensation filter for certain acoustic conditions that may exist within the listening space that could alter the performance of the loudspeaker in situ Some of these conditions are the presence of a perforated video screen in front of the screen speakers nearby room boundaries or cloth that is stretched over listening room walls that contain the speakers These filters are designed by Pro Audio Technology engineers to precisely compensate for the particular acoustic condition No knowledge of science acoustics or engineering is reguired to use them To program an amp channel for a particular compensation filter left click on the drop down list control under the Compensation heading in the GUI You will see a complete list of available filters Select the desired filter by left clicking the filter name in the list The selected filter will be loaded into the amplifier DSP for that channel and the name of the filter will appear in the drop down control in the GUI ADVANCED SOFTWARE FEATURES Certain features of PMA Manager software can only be accessed after ADVANCED CONTROLS have been activated These controls include individual channel gain adjustment and low frequency para metric EQ filters To access these controls go to the main menu SETTINGS gt ENABLE ADVANCED CONTROLS The GUI will expand and
