3.4. Can I drive 2 wire and 1-wire 96kHz at the same time?
Yes. You could use any of the A-D Factory Presets 1, 2 or 4 as a base or you could
start with the Set-up Wizard and set 96k 1-wire 24-bit output.
Then, you must modify the resulting setup to obtain the formats you need.
Starting from A-D Factory Preset 2;
Factory Preset Store 2 places the Main Output on the XLR and BNC connectors in 1-
wire (2x speed) AES-3id format. XLR1 & 2 can then be configured as 2-wire, leaving 1-
wire (i.e. 2x speed AES3) 96k on the BNC outputs.
First ensure that Factory Preset Store 2 is loaded. Press <A-D Modes>, then
<Factory Presets>, then <2>. You should see A-D:96k,24b 1XLR. Press [Enter]
to load the store.
Then, use the [99] key to select the Dig O/P Assign menu; press [Enter] and then
press [99] until the XLR2 O/P:Main display is obtained.
Use [77] to select Split96 and then press [Enter]. Check that the yellow “Link” LED
is now on adjacent to the XLR1 & 2 LEDs in the “Output Assignment” box.
Now, the XLRs are driving 2-wire and the BNCs are driving 1-wire, 2x speed AES3.
3.5. How do I do sample-rate conversion?
A common requirement is down-conversion from a high sample-rate to a low rate such
as 44.1kHz for CD release.
Press <D-D Modes>, <Factory Presets> and then <1> for 1-wire or <2> for 2-wire
and then [Enter] to load the store.
See section 2.4 for details of Factory Preset stores D-D 1 and 2. To change the output
sample rate from the preset 44.1kHz, press [99] until
Main O/P Setup is displayed, then [Enter].
Use the [77] and [66] keys to select the desired output sample-rate and then press
[Enter] to confirm the selection.
