While in the left part an AES Double Speed signal (sample rate > 56 kHz)
is being indicated automatically by the DS LED, this is not the case in
the right part. If you are not sure about the input sampling frequency,
you can still check it in the left part (by switching to AES source for a
moment).
❐
The reason for the missing automatism is the ability to convert Double
Wire to Single Wire and Single Wire to Double Wire. This is controlled by
manual activation of the DS function.
• If an AES signal in Double Wire format is present (carrier 32 to 48 kHz) and DS is
activated, the data split into up to 8 channels is being converted into the origi-
nal up to 4 channels Single Wire (64 to 96 kHz, output in Double Speed).
• This is also true for ADAT (S/MUX) and TDIF (Double Line). These signals can
also be converted to single wire double speed AES/EBU in the right part.
• If a single wire Double Speed AES signal (64 to 96 kHz) is present, the first 4
channels will be converted to 8 channels Double Wire (32 to 48 kHz) with DS
deactivated.
All those conversions are loss-less, the available samples will only be
put together or distributed between the channels.
In AES to AES mode the SRC is also available. Also placed on the left
side of the front panel, it then works for the right part of the device. This
is indicated by a quick alternating flashing of the SRC and the right AES
SOURCE LED. If the SRC is active, the conversion between Single Wire
and Double Wire as described above are not available. The DS function
only sets the output sample rate.
