44FAQ - Some Common How-To’s:1) How do I try to increase loudness while maintaining as much quality as possible?First, make sure that the input levels are set properly and that there is enough drive to the WideBand AGC.At normal program levels, the WB AGC gain-reduction meter should indicate between 12-15dB. (also see4) below) Then be sure to start with a factory preset that is aggressive enough for your needs. If the one youhave selected has all the attributes you are looking for but just needs a little more loudness, you shouldprobably first try adjusting the Clip Drive and Auto Sense per the instructions on Page 31. Also, turning upthe overall Limiter Drive can give you a loudness boost if they are running fairly lightly in the preset youhave selected.2) How do I adjust the frequency balance to obtain a certain consistent sound “signature” (more bass,less bass, more mids etc.)?This is handled mostly by the bass enhancers in the WB menu, the parametric EQ in the Limiter menuBasic tab and the 5-Band AGC section. The bass enhancers work primarily on bass-shy material so theireffect may not be audible as you turn them up if the program material already has enough bass in it. Usinga higher Bass Growl setting in the Advanced tab will generally make the bass enhancers more audible. SeePage 44 for full details. The parametric EQ should be audible most of the time although the limiters may“undo” some of what you do there. See Page 51 for full details. Overall frequency “shaping” is done usingthe 5-Band AGC. Since it works on average levels over 5 frequency bands, it acts like a “dynamic” EQ. Soif you want more bass, for example, when levels are lower, you can boost the lower bands in the XO. Thiswill act like a “loudness contour” bass boost. Similarly, you can contour the mids and highs with the XOcontrols as well so that is generally the place to start. Adjusting the output levels of each band in the Mixerwill apply a fixed amount of equalization over the frequency range of that band. Note that boosting orcutting here will have a direct effect on the corresponding limiter band.3) How do I reduce listening fatigue and create a more open, cleaner sound that can be listened tocomfortably for longer periods of time?Try backing-off the overall Limiter Drive. Too much limiter activity can cause the program material tosound more “squashed” and “tight”. Backing-off on the limiters allowing them to work only on peaks willprovide a more open sound. After adjusting the limiter drive, re-adjust the Clip Drive per the instructionson Page 31 since you may be able to use more clipping when the limiters are not working as hard. Some ofthe more aggressive presets will not respond well to these adjustments and just be aggressive all the time.At that point, it is time to start with another lighter sounding preset.4) How do I make the processor bring up the volume of quiet song intros more?This function is handled mostly by the WideBand AGC. Try increasing the Release setting in the Basic taband/or set the Window setting closer to 0 in the Advanced tab. Also ensure that your input levels are setproperly and that there is enough drive to the WideBand AGC. At normal program levels, the WB AGCgain-reduction meter should indicate between 12-15dB. Note that it is normal for the yellow gate indicatorto be on most of the time. As long as the Gate Threshold control is not set too high, the WB AGC will stillbring up low level passages. Normally the Gate Threshold is set to about -36dB. Also try a lower PauseThreshold control in the Advanced tab.In closing, starting with the right preset is really the most important thing. Always pick the one to start with thatis closest to the sound you are looking for, despite its name. Then you can fine-tune it using the information inthe rest of this chapter.
