roland keyboard amplifier

What is the better way to connect a Bass Guitar to a Keyboard Amplifier?
I have at home a Roland KC-350 keyboard amplifier (120Watt).
I want to connect a Wasbourn B15 Force ABT 4 strings Bass Guitar into one of the input channels of the amplifier.
The input level of the channel is -10dBu = ~ 0.3 volt.
I am affraid that the speaker will tear off if I'll connect it directly.
Is there a device that can limit the frequencies entering my Amplifier?
You don't need to worry about the frequencies per se, it's the impedance between the two points that is!
You want to do a search for a DI Box, Behringer do one for about £19 and that'll balance your impedance levels between the two points allowing you to select an input and output impedance so you can balance it out.
If you stick your Bass Guitar straight into it, a) you won't get the power fed to the frets and b) you'll overload the circuitry of your amplifier input...so as DI Box is the way to go!
