Do you mean an led level meter?  How about this?

An equalizer alters the sound and lets you adjust the balance of the lows and highs.

You can look up the symbols on the net.

The battery positive connects to V+ and the battery neg. connects to the ground symbol.  That's the "arrow" made of horizontal lines at the bottom of the diagram.

The center conductor of the input line connects to "input" and the outside conductor connects to the neg. terminal of the battery.

If you've never built anything like this before it might be better to start out with a kit.  It'll cost about the same but your chance of success is much higher.  The instruction are usually very clear and teach you while you build.
