3 - PCI Card & Interfaces
The E-MU 1010 PCI Card
The E-MU 1010 PCI card is the heart of the system and contains E-MU’s powerful E-DSP
chip. The powerful hardware DSP on this card leaves more power free on your CPU for
additional software plug-ins and other tasks.
Connections
EDI Connector
Connects to the AudioDock using the supplied EDI
cable. This cable provides a a two-way data link
between the E-MU 1010 and the AudioDock as well as
supplying power to the AudioDock.
S/PDIF Digital Audio Input & Output
RCA phono jacks are standard connectors used for
S/PDIF (Sony/Philips Digital InterFace) connections.
Each jack carries two channels of digital audio. The
E-MU 1010 receives digital audio data with word
lengths of up to 24-bits. Data is always transmitted at
24-bits.
S/PDIF digital I/O can be used for the reception and/
or transmission of digital data from external digital
devices such as a DAT external analog-to-digital
converter or an external signal processor equipped
with digital inputs and outputs.
The S/PDIF out can be configured in either Profes-
sional or Consumer mode in the Session Settings
menu. The 1010 PCI card can also send and receive
AES/EBU digital audio through the use of a cable
adapter.
See AES/EBU to S/PDIF Cable Adapter for
details.
The S/PDIF input and outputs are usable at the
44.1kHz, 48kHz 88.2kHz and 96kHz sample rates,
but are disabled for 176.4kHz and 192kHz. The word
clock contained in the input data stream can be used
as a word clock source.
See System Settings .
ADAT Optical Digital Input & Output
Important: When
using any type of digital
I/O such as S/PDIF or
ADAT, you MUST sample
sync the two devices or
clicks and pops in the
audio will result.
The ADAT optical connectors transmit and receive 8 channels of 24-bit audio using the
ADAT type 1 & 2 formats. The word clock contained in the input data stream can be
used as a word clock source.
See System Settings . Optical connections have certain
advantages such as immunity to electrical interference and ground loops. Make sure to
use high quality glass fiber light pipes for connections longer than 1.5 meters.
At the 96kHz or 192kHz sample rates, the industry standard S/MUX interleaving
scheme is used for ADAT input and output. S/MUX uses additional ADAT channels to
achieve the required bandwidth. See the chart below

mation.
