Activation of Follow Clock: while the firmware version is shown press the CLOCK STATE but-
ton. Both LEDs DS/QS light up. Deactivation: same, both LEDs stay dark.
5.4 AES OUTPUT
The input signal of the AES outputs is selected in the OUTPUT section. With no LED lit (no
input selected) the unit provides an empty frame signal of the current sample frequency. A
flashing LED indicates an invalid or missing input signal. Selecting the same input in the
OUTPUT section as in the SRC INPUT SOURCE section, the LED SRC indicates an activated
sample rate conversion.
AES STATE PRO (Professional) is default for the AES outputs. Selecting CON (Consumer)
provides the output signal with an SPDIF-compatible channel status.
The outputs of the ADI-192 DD support all currently known formats in the range of 32 kHz up to
192 kHz. The current output format is defined by the button STATE in the AES OUTPUT sec-
tion:
No LED (Single Wire)
8 channels 32 kHz – 192 kHz. 2 channels per AES wire. The effective sample frequency equals
the clock on the AES wire.
DW (Double Wire)
4 channels 88.2 – 192 kHz. 1 channel per AES wire. The effective sample frequency is double
the clock of the AES wire.
QW (Quad Wire)
2 channels 176.4 – 192 kHz. 1 channel via 2 AES wires. The effective sample frequency is four
times the clock of the AES wire.
All these conversions are lossless. Only the existing samples are spread on all the channels.
5.5 TDIF OUTPUT
The input signal of the TDIF output is selected in the OUTPUT section. With no LED lit (no input
selected) the unit provides an empty frame signal of the current sample frequency. A flashing
LED indicates an invalid or missing input signal. Selecting the same input in the OUTPUT sec-
tion as in the SRC INPUT SOURCE section, the LED SRC indicates an activated sample rate
conversion.
When selecting SOURCE TDIF in the TDIF OUTPUT section, some devices will generate
audio feedback, because in such a case their input and output is directly connected by the
ADI-192 DD.
5.6 ADAT OUTPUT
The input signal of the ADAT output is selected in the OUTPUT section. With no LED lit (no
input selected) the unit provides an empty frame signal of the current sample frequency. A
flashing LED indicates an invalid or missing input signal. Selecting the same input in the
OUTPUT section as in the SRC INPUT SOURCE section, the LED SRC signals an active sam-
ple rate conversion.
