RME AEB8-O Expansion Card - Open Box

Open Box Item

The AEB8-O offers 8 outputs with 4 stereo TRS jacks. Usual insert cable can be used to split the connectors from stereo jack to mono jacks. It is also possible to drive up to 4 stereo headphones directly. Level adjustment +4 dBu/-10 dBV, 106 dBA SNR and highest suppression of PC-noise guarantee perfect sound quality.

OPERATION	Top

Using the Analog Expansion Board is very simple. The AEB4/8-O operates like any other DA-converter with ADAT input, except that it is connected internally. Therefore 'Force Adat' should be activated in the DIGI96 series Settings dialog, to guarantee an ADAT output signal.

The card's optical ADAT output always works in parallel to the analog output of the AEB4-O. Two jumpers allow to choose, which of the 8 ADAT channels will be present at the 4 analog outputs.

Cards of the DIGI96 series include a freely assignable analog output. Therefore PST, PAD and PRO offer a total of 6 analog output signals with the AEB4-O.

COMPATIBILITY NOTES	Top

HDSP 9652

Two AEBx-I and two AEBx-O or two TEB can be connected and operated simultaneously, in all possible combinations. One TEB can be used together with either one AEBx-I or AEBx-O.

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.) To operate the AEB4-I and AEB8-I the used DIGIs must have the connectors ST6/7 on board (for the Word Clock Module.) These were not present on the very first cards of the DIGI96 series (1998 to beginning of 1999.)

One AEBx-I and one AEBx-O can be connected and operated simultaneously, in all possible combinations. Or one TEB.

HAMMERFALL DSP MULTIFACE / DIGIFACE

Multiface and Digiface use the Hammerfall DSP PCI card. This card has no internal inputs or outputs. Therefore no Expansion Boards can be used.

HAMMERFALL SERIES

An operation with the Hammerfall or Hammerfall Light requires board revision 1.5 or higher, because the internal connectors ADAT1Out, ADAT2Out and ST7 were not implemented in earlier versions.

One AEBx-I and two AEBx-O can be connected and operated simultaneously, in all possible combinations. Or one TEB and one AEBx-O.
