Giovani,
Audrey has given you good advice, the system she spoke of does a good job.

Each system has to be fitted to the need of the individual. For my needs, and because I want very few parts, this is what I have done.

1-Microphone goes into the Kn7000 -- the volume control is on the panel.
2-Laptop or CD player goes into the line impute -- the volume control is on the panel.
I have control of the microphone, the CD player and the keyboard –it is all at my fingertips.

I have been using powered speakers, 2 JBL 10’s the cost was $495 for each speaker. I just bought a Logitech Z2300 for my smaller needs. I can fill my home or entertain 80 to 100 people with this unit. The price at Circuit is $149. I bought the unit on line for $99. It is hard to believe but the unit is strong and very clear – and only $99.

So I have one keyboard, a mic, a Laptop or a CD player and a Logitech Z2300. Maybe a chair, and all my wires.

There players who are using the Logitech Z5500, say that it will accommodate 300 to 400 people without effort. These speakers were originally designed to be used with computers, but they work very well with all types of music.

The Z2300 has to satellite speakers and a woofer. You have a control unit for the master volume and the amount of bass (Woofer) you need.

If there is a need to have tone controls for voice or a CD then I add a small mixer, cost $59.

You must buy a system to fit your needs –sound is so subject to what we are used to.

Hope this helps, John C.
