This audio jack board replaces the original Kurzweil K250 jack board mounted to the back panel. It comes with brand new 1/4" phono TRS jacks and new XLR jacks.

     - Active feedback transformer driver, improves low frequency THD

     - Unbalanced TS High & Low outputs converted to Balanced TRS High & Low
