User's Guide AEB4/8-O
3
1. Introduction
Thank you for choosing the
RME
AEB technology. The Analog Expansion Boards add 4 or 8
analog outputs in professional quality to RME's digital audio cards. Level adju4 dBu/-10
dBV, 107 dBA SNR and highest suppression of PC-noise guarantee perfect sound quality.
2. Package Contents
Please ensure that all the following parts are included in the AEB's packaging box:
•
Analog Expansion Board
•
1 Clock cable 3-core
•
1 Data cable 2-core
•
1 Cable adapter 5 ¼" to 2 x 3,5"
•
1 Set of nuts
•
Manual, drill template
3. Hardware Requirements
AEBs can only be used with RME cards.
DIGI96 Series
AEBs use the internal ADAT interface of the DIGI cards. Therefore they do not work with the
DIGI96 (which did not support ADAT).
One AEBx-I and one AEBx-O can be connected and operated simultaneously, in all possible
combinations.
Hammerfall Series
An operation with the Hammerfall or Hammerfall Light requires board revision 1.5 or higher,
because the internal connectors ADAT1Out and ADAT2Out were not implemented in earlier
versions.
One AEBx-I and two AEBx-O can be connected and operated simultaneously, in all possible
combinations.
