6 - Using High Sample Rates

Overview

When operating at 88.2k, 96k, 176.4k and 192k sample rates, the mixer functionality and number of I/O channels are reduced. These changes are summarized in the following tables. All S/PDIF inputs and outputs are disabled at 176.4kHz and192kHz. The number of ADAT channels also decreases at the 88.2k/96k and 176.4k/192k sample rates (due to the bandwidth limitations of the optical components).

When using 88.2kHz, 96kHz, 176.4kHz or 196kHz sample rates:

•Effect processors are disabled. (Output sends & returns are still available.)

•ADAT is reduced to 4 chan. at 88k/96k, & 2 chan. at 176k/192k.

•ASIO channels are reduced to 8 stereo ASIO channels at 88k/96k, and 4 stereo ASIO channels at 176k/192k.

•At 176.4k/192k, the number of physical inputs/outputs is reduced.

•At the 176.4k & 192k sample rates, S/PDIF optical is disabled.

The ADAT optical interface was originally designed to carry 8 channels at a 48kHz sample rate. We use the Sonorus® S/MUX™ standard to encode audio with higher sample rates onto the ADAT light pipe. In this multiplexing scheme, two ADAT channels are used to carry one 88.2k or 96k stream and four ADAT channels are used to carry one 176k or 192k audio stream. In order to use the ADAT interface at these higher sample rates, you must have other equipment that supports the Sonorus S/MUX standard.

E-MU 1820 System at 88.2k/96k (1010 PCI Card & AudioDock)

All outputs remain active at 88.2k/96k, but the number of ADAT channels is reduced from eight to four (see above). There are two possible input conﬁgurations when using the E-MU 1820 system at 88.2k/96k as shown in the chart below. Basically, you have the option of using the (4) ADAT input channels or (4) Line Inputs (Line Inputs 2 and 3). At 88.2kHz/96kHz the headphone output parallels the Monitor output and is no longer independently assignable.
