In anticipation of receiving my SSV3 hopefully in the next few weeks, I decided to review this thread for basic practical information. This is kind of a poor mans faqs, omitting anything I personally dont care about (technical explanations how the unit works, comparisons with other amps, explanations for using subs, etc). This is what I came up with. Much of this consists of unattributed quotes from other posts. Hopefully, my editing did not change actual meaning.
Ive organized this by categories (which I will put in separate posts). First up....
Settings on the V.3
The width level sets the balance between the front and side systems. Use the Width control to balance the Side speaker level (L-R, the unique and "widest" parts of the stereo signals) with the Front speaker (L+R, or the mono compatible parts of the stereo signals). The wider patches will bring out more side level, and so you will hear far more pronounced differences b/w the various AP patches than you would in your former mono system.
Start with the width at "0", then set the Level (Front speaker only now) to the desired volume. Then bring up the Width level until the stereo image is "just right", or to the point where is sounds natural (like it might sound thru stereo headphones). The farther away you stand, the better you can judge the stereo image, and your level. When you are "wide", you do not need to be as "loud" as you have in past.
Usually, the Side Level will sound best around 12 o'clock. If in a hurry, just set the Width "straight up", and season to taste from there. But that "sweet spot" balance can change depending on the environment. Use more Width for a "dead" room (full of people who absorb sound) or for outdoor gigs that have no reflection points, and usually less Width required for a "Live" room.
On the amp itself, normally go with the width setting at 12:00, and treble maybe at 2:00.
Stated differently: start by "tuning" the Front speaker alone, in mono (this Front speaker system is a tri-amp affair), so set all controls fully down (left)...except level of course. This means you will hear just the woofer and it's own amp...so it will sound a bit muffled (as it should w/ no MF or HF content) but now you can "season to taste".
Next, and best if you have a auto play song mode (as many KB do), set it on "play" and begin the tuning of the Front speaker in the mono mode by 1) cranking up the "Mid Level", that is the co ax compressions driver, driven by it's own amp. MF is designed to be "normal" around 12 o'clock....but if you want more "punch" 1-2 is maybe better but be careful, you do not want "harsh".
Then 2) bring up the HF control. Try using strings or synth for setting setting this level, as you won't hear much HF on a Hammond/Leslie or EP patch. Maybe 2-3 o'clock is the right spot for HF. But as the HF component is quite "high", silky territory, so it will not really offend if set too high...certainly not nearly as much as compared to the MF component if set too high.
Now once you have the Front sounding the way you like, 3) bring up the WIDTH, maybe around 12 o'clock.
