Congratulations!
You are now the proud owner of the Crate XK50 keyboard amplifier. This compact powerhouse fea-
tures a 12” Crate Custom woofer and a Piezo tweeter housed in a ported tuned enclosure. Each of its two
input jacks has its own level control so you can mix your keyboard with another instrument or a high-Z
mic. The CD input jacks allow you to play along with your favorite music. The Insert jack allows you to
connect external effects to the to the amp and doubles as a line out jack to send a signal to a recorder,
mixing board or house PA. The headphones jack allows for private practice sessions.
The XK50’s angled cabinet allows you to use it as an upward projecting floor monitor or stand it
upright like a conventional amplifier.
Like all Crate products, your XK50 is designed by musicians, and built using only the best compo-
nents. 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
XK50 Keyboard Amplifier
