6 - Using High Sample Rates
Overview
E-MU Digital Audio System 89
E-MU 1820 System at 176.4kHz or 192kHz
(1010 PCI Card & AudioDock)
At the highest sample rate you have 4 inputs and 10 output channels.
There are four possible input configurations when using the E-MU 1820 system at
176.4kHz or 192kHz. Each of the three options provides four input channels.
S/PDIF is not specified to operate at 176.4kHz/192kHz and so all S/PDIF inputs and
outputs are disabled. The headphone output parallels the Monitor output and is no
longer independently assignable, just like at 96kHz.
E-MU 1212 System at 176.4k/192k (1010 PCI Card & I/O Card)
At 176.4kHz or 192kHz, you have two 24-bit inputs and outputs. S/PDIF is not
specified to operate at these rates and so all S/PDIF inputs and outputs are disabled. The
ADAT input/output channels are reduced to two channels (S/MUX standard).
• Microphone Input and Line 2 Input enabled
• Microphone Input and ADAT Input enabled
(2-chan ADAT)
• Line 1 Input and ADAT Input enabled
(2-chan ADAT)
• Line Inputs 1 & 3 enabled (allows use of turntable inputs at 192kHz)
