The AEB4-I (Analog Expansion Board) adds 4 analog inputs in professional quality to all ADAT capable cards of the DIGI96 series. Level adjustment +4 dBu/-10 dBV, 107 dBA SNR and a servo balanced input circuit deliver perfect sound and sonic clarity.
The AEB4-I is designed for maximum flexibility. Both stereo inputs 1/2 3/4 are automatically copied to channels 5/6 and 7/8. Installation is done in a convinient manner using the supplied bracket, or - as no contact to any slot on the motherboard is needed - at any place inside the computer. Nuts for all TRS jacks and a drilling template are included.

Notes on Compatibility
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.
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.
