OWNER’S MANUAL

Congratulations!

You are now the proud owner of the Crate KX-160 keyboard amplifier. This versatile and great sounding amp features a 15” Crate Custom woofer and a Foster bullet tweeter housed in a ported tuned enclosure. Each of the four discrete channels has its own gain and reverb/effect control while two of the channels have separate low and high rotary EQ controls as well. The Master section features a 7-band graphic equalizer, balanced and unbalanced line out jacks with a level control, two effects loops and footswitch-controllable reverb.

Like all Crate products, your KX-160 is Musician Made in the U.S.A., using only the best components. Extensive testing at the hands (and ears) of skilled technicians and musicians insures you that this amplifier is the absolute best it can be.

In order to get the most out of your new amplifier, we strongly urge you to go over the information contained in this manual before you begin playing.

And thank you for choosing

I M P O R TA N T N O T E A B O U T S P E A K E R J A C K S :

In some areas 1/4” speaker jacks are not acceptable for use on amplifiers capable of high output power levels. For this reason the 1/4” jacks on your KX-160 may be factory sealed – in such cases, use the Speakon® jack provided for connecting the amplifier to external speakers. Use heavy duty speaker cables terminated with the proper connectors.
