The RB-SC2 is a dual sample rate converter in a 1-rackunit format. It produces AES/EBU, SPDIF and TOSlink optical level digital audio outputs from balanced AES/EBU, SPDIF and TOSlink optical level digital audio inputs.
It is possible to set the sample rate of the outputs by means of an internal clock or from an external synchronizer source.
In addition to features available on the RB-SC1, the RB-SC2 supports higher sample frequency rates — up to 176.4 kHz and 192 kHz — and has two independent sample rate conversion circuits that use a common clock source to set the output sample rate.
The RB-SC2 also has a special X-Lock mode that allows the unit to function as a fully bidirectional sample rate converter with the output of the first sample rate converter synchronizing the input of the second sample rate converter, and vice versa, so that they follow each other.
Therefore, it is possible to insert the RB-SC2 between two digital devices running at different sample rates, such as between a PC recorder and a digital player, and ensure that the two devices remain synchronized at all times.
