Abbreviations \"What the heck does THAT mean?\"
Well.. here is an ever expanding list of abbreviations, and acronyms.. if your favorites aren't here PM me and I'll include them...
GUI...Graphic user interface...allows you to control the 200 series, 1200 series and zone pro, and 480 series with a computer. You can modify and run the different modules and set up the unit. Auto Eq is not available.
PEQ... Parametric equalizer, a Equalizer that has a low shelf, a high shelf or a bell curve. Bell filters offer center frequency selection, 'Q' (amount of the entire frequency spectrum you want to affect, be it octaves wide or very very narrow) Shelf filters have frequency, slope and gain...parameters
GEQ...Graphic Equalizer.. I assume an old sound man like you knows what that is?
AFS...Automatic feedback suppressor. 12 bands of filters that can be either fixed or roaming...
Sub Synth.. Sub harmonic synthesizer ... as it's name indicates it synthesizes sub bass frequencies that aren't there...
Auto Eq...with a dedicated measurement mic and a lot of knowledge, you can set your speakers up.. and if your good, or lucky, you can help your sound in certain rooms..but beware!
db... Decibel.. a measure of sound pressure in bells
PFL... Pre fader listen. A feature on mixing consoles that lets you \"preview\" the signal BEFORE it reaches the fader...
AFL... after fader listen.. as above but --after the fader
Hi, Mid, Low refers to the high frequencies, midrange frequencies, and Low frequencies...
Aux fed subs... read the FAQ blurb on it...
http://www.dbxpro.com/forum/viewtopic.php?t=1469
DIY...Do it yourself
SPL... sound pressure level...usually measured in db's
USB.. and other computer language...see computers..or google search
HPF...high pass filter... the LOWEST frequency you want the speakers to produce. On the subs we usually suggest a VERY steep falloff to protect the drivers from over excrusion
LPF...Low pass filter...the HIGHEST frequency we want the speaker to produce...When placing xovers next to each other (as in the HPF for the tops and the LPF for the subwoofer ... use LIKE xover types, Example we often suggest an LPF for the sub of 100 hz LR24.. we would therefore look at a 100 hz LR24 HPF for the tops)
NOTE the DRPA does NOT have an LPF on the HI outs...
BW 18, LR24, Bs6... these are crossover types:
LR= Linkwitz Reily
BW+ Butterworth
BS= Bessel
Each exhibit different characteristics, generally the lower the NUMBER the LESS steep the slope of the crossover and the MORE interaction you can expect in the crossover region...We prefer BW 18 or 24 for the sub HPF, to protect the speaker from over excrusion... the HIGHER the number...the greater the complexity of the filter, and the MORE anomalies will be affecting the sound in the xover region.. like phase induced errors, frequency combing, alignment issues...We prefer LR24 for the predictable nature of the adjacent slopes and frequencies. Other manufacturers also seem to gravitate to this slope...regardless it is simple to change and evaluate for yourself.. each and every one of the different types and slopes with the Driverack...
If you want to circumvent this mess, simply Google (OR...insert favorite search engine here) and you'll be able to help yourself with any word or abbreviation you would like to find out about...
