18. Analog Connections
18.1 ADAT
The ADAT optical I/Os of the RayDAT are fully compatible to other ADAT devices. RME's un-
surpassed Bitclock PLL prevents clicks and drop outs even in extreme varipitch operation, and
guarantees a fast and low jitter lock to the digital input signal. A usual TOSLINK cable is suffi-
cient for connection.
ADAT 1 In
Interface for a device sending an ADAT signal to the HDSPe RayDAT. Carries the channels 1 to
8. When receiving a Double Speed signal this input carries the channels 1 to 4, at Quad Speed
channels 1 and 2.
ADAT 1 Out
Interface for a device receiving an ADAT signal from the HDSPe RayDAT. Transmits channels 1
to 8. When sending a Double Speed signal this port carries channels 1 to 4, with Quad Speed
channels 1 and 2.
ADAT 2/3/4 In
Interface for further devices sending an ADAT signal to the HDSPe RayDAT. Carries the chan-
nels 9 to 32. When receiving a Double Speed signal, these inputs carry channels 5 to 16, in
Quad Speed mode channels 3 to 8. ADAT4 can also be used as SPDIF optical input
ADAT 2/3/4 Out
Interface for a device receiving an ADAT signal from the HDSPE RAYDAT. Transmits channels
9 to 32. When sending a Double Speed signal, these outputs carry channels 5 to 16, in Quad
Speed mode channels 3 to 8. ADAT4 can also be used as SPDIF optical output.
18.2 AES/EBU
The RayDAT’s digital breakout cable (BO968) provides one XLR AES/EBU input and output
each. Connection is accomplished using balanced cables with XLR plugs. Input and Output are
transformer-balanced and ground-free.
Besides the audio data, digital signals in SPDIF or AES/EBU format contain a channel status
coding, which is being used for transmitting further information. The incoming channel status is
ignored.
The AES/EBU output
’s channel status has been implemented according to AES3-1992 Amend-
ment 4:

32 / 44.1 / 48 kHz, 64 / 88.2 / 96 kHz, 176.4 / 192 kHz sample rate
