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. Output AEB4-O 4 x 1/4" TRS

(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
