Overview
The AEB4-O (Analog Expansion Board) adds four analog outputs in
professional quality to all ADAT capable RME cards. Level
adjustment +4 dBu/-10 dBV, 106 dBA SNR and a servo balanced output
stage deliver perfect sound and sonic clarity. The AEB4-O is
designed for maximum flexibility. Jumpers allow to route channels
1/2 3/4 or 5/6 7/8 to the four analog outputs. 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.

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.

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.

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 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.
