The RXEQ built into the K3 is capable of about 36 dB of combined high 
frequency boost and low frequency cut.  This won't be enough to 
compensate for really severe hearing loss, but it can an effective 
solution for the majority of folks. As a starting point, set the four 
lowest bands to maximum cut, leave the fifth band at zero, and the 
remaining bands gradually increasing in boost until it sounds good to 
you. Those with more serious loss will usually want boost be greater on 
those higher bands. The most important octave for speech is 2 kHz, 1 kHz 
is next, then 4 kHz. So with severe hearing loss, you will generally 
want the top three bands up full.

I would do this before I would consider an external equalizer.
