The s/pdif data rate will be determined by the sample rate selector button on the front of the flying calf. Panels - fig. 1 ...

7 after all connections are made, power up the flying calf by pressing the power button on its front panel. Important: before powering up the flying calf, turn off or turn down any amplifiers, mixers, or audio converters connect- ed to the flying calf's s/pdif output. Since it may take several milli...

8 the level of the analog signal that goes into the flying calf should be adjusted for optimum a/d sampling quality. For best conver- sion, the input signal should have enough amplitude to take advantage of nearly all 24 bits of a/d resolution. In other words, peak levels of the incoming audio signa...

9 internal jumper settings there are four configuration jumpers inside the flying calf chas- sis. Typically you will never need to open the flying calf and adjust these jumpers. For some applications, however, it may be required. Jp2 and jp3 are used to set the input levels for the left and right ch...

Jumpers jp2 and jp3 control the input levels to the left and right audio channels, respec- tively. When set to the "standard" position, they accommodate most signals (-10 dbv nominal). When set to the "+6" position, they can accept signals that are 6 db weaker (-16 dbv nominal). The positions and se...
