I must admit that I have never played the Tyros through the 5500 system, therefore I do not possess first hand knowledge of the sound difference. However, the settings that are kicking butt for me with the 3000 are EQ-1=4, EQ-2=3, EQ-3=4, EQ-4=8, EQ-5=10.

The mic settings I've having the most success with are:

LOW/MID/HIGH
80/+2 2.0/+0 10k/+9

Noise gate Compressor
Off/-60 on/-20/5.0/110

play/off/lower/L35>H/auto/XF/off/vol=85

Naturally, the mic settings will vary to some degree, depending on individual make and models of mics.

Keep in mind that I'm not firing through a mixer unless I'm performing with other musicians, which is extremely rare. Yesterday was one of those rare exceptions. The first job was a 1-hour assisted living center where I perform every month. Very large, three-room complex and the rooms are divided by half-walls topped with decorative spindle posts. I'm set up in the center (largest) room with measures approximately 30 X 60 feet and in a corner of that room. The Z-5500 fills not only that room with sound, but the others as well. And, while there is obviously some volume loss in the other adjacent rooms, it's not significant enough to turn the volume higher in order to attain quality sound in those rooms. Audience here consists mainly of folks with Alzheimers, but there is usually a dozen or so staff in the room who love what they hear--otherwise I would be history.

The second job was in Baltimore's Little Italy at a Son's Of Italy hall that is long, narrow and another two room deal. The room I perform in measures about 30 X 20 feet and has an opening measuring approximately 15 feet wide that opens to the second room that measures about 30 X 80 feet. The larger room is solid with dining tables, folks are talking, feasting on Italian cuisine and enjoying the music. Last night, I used the Z-5500 system there for the first time, hoping that it would provide quality sound and cover both rooms better than the Barbettas--it did. The Barbettas have a lot more power, move a lot more air with those big 15s and the 10-inch horns, but I really had to power them up to reach the back end of the second room. With the Z-5500, I cranked the main volume up to Boost 11, but only had the sub at about 20 percent and the keyboard, which everything runs through, was only turned up half way.

The bottom line is that everyone there, which was about 125 people, raved about the music, many complemented me about how wonderful the vocals sounded, and while there was some perceptable falloff from one end of the venue to the other, it was not significant enough to warrant more volume. The falloff was modest at best. For me, the Z-5500 is perfect, and I base my volume and quality decissions upon not only what I hear, but additionally, my audience's responses. Hey, they're the ones signing the checks.

BTW: I did try the JBL10's with the 3000 and for me, they were OK, but I personally like the sound of the Logitech Z-5500 better.

Good luck,

Gary
