The Expansion Boards transmute RME's digital cards of the DIGI96 series, Hammerfall series and the HDSP 9652 into the most flexible audio cards available.

The AEB4-I (Analog Expansion Board) adds 4 analog inputs in professional quality to all ADAT capable RME cards (see below). Level adjustment +4 dBu/-10 dBV, 107 dBA SNR and a servo balanced input circuit deliver perfect sound and sonic clarity.

Installation is done in a convenient 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.
