In case the output should operate as line
output, an adapter TRS plug to RCA phono
plugs, or TRS plug to TS plugs is required.
The pin assignment follows international
standards. The left channel is connected to
the tip, the right channel to the ring of the
TRS jack/plug.
21. Digital Connections
21.1 ADAT
The ADAT optical inputs of the Fireface 802 are fully compatible with all ADAT optical outputs.
RME's unsurpassed Bitclock PLL prevents clicks and drop outs even in extreme varipitch op-
eration, and guarantees a fast and low jitter lock to the digital input signal. A usual TOSLINK
cable is sufficient for connection.
ADAT1 In
Interface for the first or only device sending an ADAT signal to the Fireface 802. Carries the
channels 1 to 8. When receiving a Double Speed signal, this input carries the channels 1 to 4,
at Quad Speed the channels 1 and 2.
ADAT2 In
Interface for the second device sending an ADAT signal to the Fireface 802. Carries the chan-
nels 9 to 16. When receiving a Double Speed signal, this input carries the channels 5 to 8, at
Quad Speed* the channels 3 and 4. Can also be used as SPDIF optical input.
ADAT1 Out
Interface for the first or only device receiving an ADAT signal from the Fireface 802. Transmits
channels 1 to 8. When sending a Double Speed signal, this port carries channels 1 to 4, at
Quad Speed the channels 1 and 2.
ADAT2 Out
Interface for the second device receiving an ADAT signal from the Fireface 802. Transmits
channels 9 to 16. When sending a Double Speed signal, this port carries channels 5 to 8, at
Quad Speed* the channels 3 and 4. Can also be used as SPDIF optical output.
* With Windows USB the ADAT channels 3/4 are not available at 176.4 and 192 kHz.
21.2 AES
The Fireface 802 provides one XLR AES/EBU input and output each. Connection is accom-
plished using balanced cables with XLR plugs. Input and Output are transformer-balanced and
ground-free. The incoming channel status is ignored.
AES/EBU (and SPDIF) can contain Emphasis information. Audio signals with Emphasis have a
strong high frequency boost, requiring high frequency attenuation on playback.
An Emphasis indication gets lost as there exists no standardized interface on computers to
handle this information!
