BELAR DSD-1A DIGITAL STEREO DECODER
The Belar DSD-1A is a precision FM stereo decoder. It produces 48 kHz AES/EBU digital stereo audio by digitally demodulating analog stereo composite signals. The DSD-1A also provides balanced analog Left, Right, L + R, and L - R outputs on XLR connectors.
The DSD-1A features two front-panel peak level indicators to maintain constant transmission levels. The user adjustable ACTIVITY LED monitors composite activity, while the fixed OVERLOAD LED warns of possible overload.
The DSD-1A is suitable for applications that require digital stereo signals or precision analog left and right stereo signals. Such applications include: obtaining a digital input for use with digital FM exciters, demodulating composite STL's for AM stereo, obtaining digital audio for digital transmission of house monitors, etc.
