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.

ADAT or S/PDIF Optical In/Out

Firewire

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

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 or go here for additional infor- mation.

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.
