The DA302A DARS Generator card is used to generate digital audio reference signals. This unit offers two copies of three independent outputs. Outputs one and two may be programmed to provide tone or digital silence, while the signal on output three is a word clock.

The DA302A may be programmed to provide signal levels of 0, -12, -14, -16, -18, -20, or -60 dBfs at frequencies of 400 or 1000 Hz.

The output signals of the DA302A may be referenced to the internal 48 kHz oscillator, an external AES signal (22 to 96 kHz), or to an external composite video signal. Resolution of the output signal is selectable between 20 or 24 bit.

Status LEDs on the front edge of the card indicate whether the card is locked to an external reference signal, its internal 48 kHz oscillator or if there is a signal error.

The DA302A can be installed in any position in the MF100 or MF104 Serialboxx frame. The 75 Ohm AES input and output signal connections are made via 75 Ohm BNC connectors.
