AES digital outputs
The AES1 and AES2 outputs (A & B) can be used individually at 44.1, 48, 88.2, 96, 176.4 or 192kS/s
or DSD/64 in DoP format, or as a Dual AES pair at 88.2, 96, 176.4, 192, 352.8 or 384kS/s or DSD/64
or DSD/128 in DoP format.
!
Dual AES mode is automatically selected if the file rate is equal to or higher than the rate
set in the app’s
Configuration > Dual AES Sample Rate section. At lower rates, both
AES outputs will carry the same single AES data.
SPDIF digital output
The SPDIF output on an RCA connector (C) carries SPDIF data for output rates at 44.1, 48, 88.2, 96,
176.4 or 192kS/s or DSD/64 in DoP format, even if Dual AES mode is On . The output rate is
controlled by the app’s Configuration > SPDIF Downsampling section.
SDIF-2 digital interface
The SDIF-2 interface carries either SDIF-2 PCM data at sample rates up to 96kS/s, or SDIF-2 DSD/64
data. The interface consists of two data inputs labelled CH1 and CH2 (D). The Word Clock Out put (E)
must be connected to the DAC to provide clocking for this interface, unless a Master Clock is in use.
High sample rate data is automatically downsampled to either 24/88.2 or 24/96.
WiFi antenna connector
Antenna socket (F) for the internal WiFi feature – this is for future development.
Word Clock inputs and output
Either of the two Word Clock In connectors (G) will accept standard word clock from a master clock at
44.1, 48, 88.2, 96, 176.4 or 192kHz. The clock frequency MUST be an exact multiple of the file data
rate, otherwise the system will not lock.
Each of the Word Clock In puts may be used individually. To make operation easier, you can connect
a 44.1, 88.2 or 176.4kHz word clock to Word Clock In1 and a 48, 96 or 192kHz word clock to Word
Clock In2 . The unit can then select the clock frequency that is an exact multiple of the file data rate.
The (SDIF-2) word clock Out connector (E) carries a word clock at the same frequency as the file data
rate, up to 96kHz. You can connect this to the DAC to improve data transmission. This connection is
required if the SDIF-2 output is in use.
Word clock is used for synchronisation only, it does not carry digital data.
