SPDIF x2 • ADAT x2
Figure 17.7: MH EdgeCard: SPDIF x2 • ADAT x2
The SPDIF x2 • ADAT x2 EdgeCard provides two independent RCA copper SPDIF I/O ports plus
two independent ADAT/TOSLINK optical digital I/O ports.
EdgeCard optical input ports auto-sense and auto-configure to the incoming digital audio stream,
whether TOSLINK stereo or ADAT S/MUX.
The output format for each optical port is manually selectable, and is independent of the input
format of the selected port.
Due to a physical interference in both the 2882 and ULN-2 chassis, it is not possible to
insert the SPDIF x2 • ADAT x2 EdgeCard into the EdgeBus Card Slot on these models.
As a result, this card is not compatible with either the 2882 or ULN-2.
The SPDIF • ADAT x2 and all other EdgeCards fit perfectly in the 2882 and ULN-2 (and
all other 3d hardware units).

ADAT x4
Figure 17.8: MH EdgeCard: ADAT x4
The ADAT x4 EdgeCard provides four independent ADAT/TOSLINK optical digital I/O ports.
As with the built-in ports on the 2882 and ULN-2, each optical EdgeCard input port auto-senses and
auto-configures to the incoming digital audio stream, whether TOSLINK stereo or ADAT S/MUX.
The output format for each port is manually selectable, and is independent of the input format of
the selected port.
• TOSLINK mode supports stereo audio at all sample rates from 44.1k to 192kHz.
• ADAT mode supports standard ADAT and ADAT S/MUX formats, providing eight channels of I/O
at 1x sample rates, four channels at 2x, and two channels at 4x sample rates.
