New for 2004, we are introducing an entirely new range of acoustic amplifiers. The technology in the New Crate Acoustic Series is unique, with preamp circuits you can tailor for piezo or active systems or BOTH!!. Our NEW feedback elimination circuits are efficient and simple to use and on the 60 and 120 watt units include the ability to automatically eliminate feedback at two different frequencies. Every CA amp has a high frequency component for crisp, clear highs. On the CA6110DG, CA125DG and CA120DG models we include special features for live performance like XLR & 1/4" balanced line out with Level control which does not affect your stage volume. They also have ground lift on the Line Out, Tweeter Level control, Effects Loop and a two button footswitch for Internal Reverb/Effects and Chorus switching.
