Summary of Contents for RB-SP1

Page 1: ...al mixing desks by splitting the left and right signals of a stereo XLR to two separate XLR s and vice versa by combining them Additionally a sample rate converter on the second digital input can be used to convert the sample rate of the secondary input to that of the primary input The RB SP1 can handle sample rates up to 96kHz and sample sizes of 16 20 and 24 bit There are two types of operation ...

Page 2: ...older equipment to handle 48kHz double sampled 96kHz digital signals To do this Split 96 uses two digital signals running at 48kHz where both sub frames of a single 48kHz stream are used to carry information about a mono signal with the resultant signal of both 48kHz streams being equivalent to a stereo 96kHz signal The unit will also perform the same function for 88 2kHz stereo and 44 1kHz double...
