gain setting?

[endofdays89 5,000+ posts]

i put it on 4, set my gains, and im leaving it on 4. id bring it down to like zero, but for some reason my mids dont sound as good.

I had the same problem. I guess if you like to listen to the radio alot and switch it back and fourth you may want to put it on 0, but if you dont listen to much radio it sounds better a +4. Its easier to get power that way.

I also have an sla, and the majority of the responses here are either bad presumptions or completely bs guesses...

It is a source level adjustment. It affects not only the radio, but the cd as well as auxilary inputs as well. It does not "increase the volume by +4" or do anything like that. It is like a gain for the HU. Your amp has a gain setting, which is for adjusting the amp so that it compensates for weaker or stronger input signals. SLA on a HU does just that. It adjusts its input sensitivity to make up for stronger or weaker input levels (or recording levels of music).

Personally, the way I use it is for compensating for the fact that the 0db test tone you set gains with is much louder than most music will ever be. I set my gains, turn the volume all the way up, and then check on a heavy bass song how far I can turn up the SLA without clipping or sending too much power to my subs, and then I use that as my "full tilt". So, currently, if I turn up my HU to 50 (where I set my gains) with SLA at +2, music comes through just as hard as test tones do with SLA at 0.

thats more of the answer i was looking for. i had a feeling it didnt just increase volume by +4, because my mids and highs get a lot louder when i turn the SLA from say 0 to 4, and if i bring it down to -4, you can barely hear them even with the volume like half way up.

ill try doing what you said tomorrow. still have a lot more fine tuning to do.

Read the Pioneer manual //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

BTW your radio doesn't have input sensitivity, there is not a single POT on an internal amplifier to adjust this, its a fixed setting that increases with volume.

I've read the manual, it uses radio sensitivity as its reference level, and if its not exactly as I described it, it behaves exactly that way, so I see no problem in using it that way.

The way I understood it was this..

When you change source settings if there is a difference in volume, you use the SLA to change the volume settings between the sources.

The way I understood it when I read it was that it increases or decreases the volume

also radio sensitivity as being FM radio sensitivity, not input sensitivity

im not sure how much of a volume gain you guys are experiencing when you raise the SLA, but i notice a dramatic volume gain from say 0 to 4. definetely more than just raising the volume by 4.

Yea, to me, if I had to guess, i'd say its like raising the volume by 10-15, maybe more from 0 to 4. Just try setting it the way I told you andyou should be fine, as long as you use a 0db test tone initially
