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. Unlike the original boards, this board has an active feedback amplifier for the two audio line outputs, providing improved THD for low frequencies. The board comes with LePro-Audio Lehle brand transformers with extremely low distortion and excellent EMI noise suppression from Mu-Metal shielding encasing each transformer.
Additional key benefits:
- Unbalanced TS High & Low outputs converted to Balanced TRS High & Low
- Line Input jack has 48V Phantom Power switch to direct power microphones
- Frequency response switch for Line / Mic input. Flat or HF pre-emphasis
- Built in DI boxes with Ground Lift switches for Line Out and Line In
- No soldering required, easy to install
