Internal Sync
when the analog inputs are selected, sychronisation is derived by default from a
fixed internal 48kHz clock, and the digital output clock is derived from this internal
clock.
External Sync
To use the analog to digital conversion of the DnS 2 at a sample rate other than
48kHz, or to lock its digital outputs to house sync, connect an aeS3 or aeS11 sync
signal to the digital input. The front panel sync leD will show green, and the DnS 2
will automatically synchronise to the external signal. Operation at 44.1kHz, 48kHz
and 96kHz is supported.
Gain
Press the SeTuP button to monitor the input signal level on the displays. If desired,
you can use the encoders to adjust the gain of the analog input for each channel.
Press the SeTuP button again to return to the process control page.The operations
of the controls and displays will also revert to process control page after a short
idle period.
Digital input
Set the input selector switch to DIGITal In (switch to right) and connect an aeS
digital source to the digital input Xlr. Connect the digital and/or analog output
Xlrs to suitable inputs on your recording or monitoring equipment.
The unit will lock to any aeS3 signal with a sample rate of up to 96kHz that is
presented to its inputs. Operation is supported at 44.1kHz, 48kHz and 96kHz.
Sync
If the input selection switch is set to digital and no valid digital signal is present
at the digital input, the SYnC leD will light up red and the DnS 2 will not process
audio.
Enabling the analog outputs
The analog I/O accounts for about one third of the DnS 2’s power consumption. To
save power, it will shut down when the digital input is selected, resulting in digital-
to-digital operation.
To use the DnS 2 “digital In, analog OuT”, you can re-enable the analog outputs
by pressing SeTuP to enter the setup page and then pressing both DnS On
buttons simultaneously. repeat this operation to switch the analog outputs off
again.
USB
There is a USB socket for updating the firmware.
