The only good local installer here in Bali just lent me his RTA. It’s a PHONIC PAA2. He don’t speak English well enough to understand the manual, so he wants me to read it, then teach him how to use the thing. In return I get to use it for a few days, whoopie! Only thing is I don’t understand half the terminology! I thought I could just read the manual a bit, turn this baby on, take a reading of the 31 bands, and off we go. Ain’t so simple. So, can anybody help? To wit:
1. I get a choice of response time. Why? And which one do I want? The choices are 35ms 125ms 250ms and 1 sec. Manual is no help in explaining. Seems to me you would just want the fastest possible, no?
2. You need to pick a “weighting” setting. Huh? I get a choice of “A”, “C” and “Flat”. All calibrated according to “American National Standards Insititue”.
Reassuring, but what the hell are they talking about? Intuitively, “Flat” sounds like the right one, doh, but the manual says that “A” is the most frequently used weighting type. Well, OK., but nowhere in the manual does it tell you what the hell all this means. So what one do I want? “A”? Why?
3. It has a pink noise generator if you don’t have one yourself. But no white noise. Now waitta minute. I thought that WHITE noise is the one you want to use to get a flat frequency response, cause pink noise is skewed towards the lower frequencies, whereas white noise is flat. Right? Wrong?
Anybody help with this and you get two free beers on your next trip to Bali. And you would have helped bring ever better car audio to the small group of fanatics down here. Thanks.
