enable/disable optically isolated input with front panel LED indicator; balanced

nals; RS-232 tone detection port; front panel input audio presence and overload
LED’s and level control. The DSD-2 is powered by a surge protected internal bi-
polar 15vdc power supply affording superior headroom and high definition audio.
