Analog Expansion Boards for Hammerfall®
Series,
HDSP 9652 and DIGI96® Series

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. |

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.

 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.
