Q: What is the maximum sample rate that the 7-Series recorders support? Do they accept a 24/192 signals from external digital sources?

A: The 702, 702T, 722, and 744T recorders support sampling rates up to 192 kHz and will lock to external digital sources with rates up to 200 kHz. If the units receives external word clock sync or AES sync, the file will be "stamped" with the sampling rate closest to the internal rates of 32, 44.1, 47.95, 48, 48.08, 88.2, 96, 176.4, and 192 kHz.

The 788T recorder records sampling rates up to 96 kHz. When the Setup Menu option REC: SYNC REFERENCE is set to Internal, the Sample Rate Converters will be applied to any incoming AES signal.

The 788T has high-quality, hardware sample rate converters (SRCs) on each of its AES/EBU digital inputs. The 788T’s digital inputs accept AES signals with sampling rates from 32 kHz to 192 kHz.

With the sample rate converters each digital input can be fed with signals of any sample rate without having to word clock all of the devices together.

The SRCs are only active when needed; when not needed they are deactivated. To use digital inputs without the SRCs active, set the REC: SYNC REFERENCE Word Clock Input, Video Input, or to an AES input pair.
