Weiss SFC2 Sample Converter

The Weiss SFC2 Sample Converter is a versatile sampling frequency converter with two completely independent stereo converters in a single 19 inch unit. With a high order, linear phase and digital low pass filter, the SFC2 offers no coefficient jitter, no filter modulation, and more transparency.

The Weiss SFC2 Sample Converter is designed to integrate playback or outboard equipment into an environment that either runs at double- or standard-sampling frequency. To allow this equipment to be positioned anywhere in the processing chain, the Weiss SFC2 features two completely independent two channel sampling frequency converters, A & B, to simultaneously down- and up-sample a signal. Alternatively, it can also be used to convert the sample frequency and reduce the word length of any two arbitrary audio signals at the same time.

Standard sampling frequency converter chips continuously measure the input frequency and then generate the output frequency and the filter specifications accordingly. This results in coefficient “jitter” because the input signal sampling frequency jitter modulates the cutoff frequency of the digital filter. The Weiss SFC2 Sample Converter uses a fixed-ratio scheme where the output is directly derived from the input sampling frequency – therefore no coefficient “jitter”, no filter modulation, more transparency.

Weiss SFC2 Sample Converter Features
