CONNECTING THE SYSTEM
Audio Connections
Connect audio connections as shown in the diagram below. ADAT Optical cables must be connected from
the ADAT Out ports of the Sonorus StudI/O card to the ADAT In ports of the 328XD and vice versa. With
the optional Sonorus syncplate fitted a BNC wordclock cable should be connected from the 328XD
wordclock output to the Sonorus syncplate wordclock input.
The ADAT connections allow digital transfer of either direct output for input channels 1-16 to the Sonorus
StudI/O card, or the 328XD’s 8 Group outputs.

328XD CONFIGURATION
Wordclock
To configure the 328XD as the wordclock master, enter the 328XD Menu pages by pressing the
<MENU> button on the right hand side of the LCD display. Using the PARAM encoder, scroll up or down
until the ‘Clock Source Sel’ menu is highlighted, and press <ENTER>. Here, either the internal 44.1kHz
clock or the internal 48kHz clock must be selected, depending on the sampling rate at which work is to
be done. Press <ENTER> to set the sample rate and <MENU> to return to the menu pages.
To ensure that the 328XD Tape Ports are set to ADAT to work with the Sonorus StudI/O, enter the 328XD
Menu pages by pressing the <MENU> button on the right hand side of the LCD display. Using the
PARAM encoder beneath the display, scroll up or down until the ‘Tape Port Select’ menu is highlighted.
Press <ENTER> and press the Up cursor arrow until the ‘<Tape Ch17-24 >’ menu page is displayed.
Using the PARAM encoder set the Bank Source to ADAT.
Press the Down cursor key to set the wordlength. The Sonorus StudI/O is capable of 24-bit recording,
and so for optimum results, 24-bit wordlength can be selected here. If your audio sequencer software
does not allow 24-bit recording, 20-bit or 16-bit should be selected. The sequencer manuals should be
consulted for further information. The wordlength is set on the 328XD with the PARAM encoder. Press
<ENTER> to set the wordlength and <MENU> to return to the menu pages.

STUDI/O CONFIGURATION
Wordclock
The Sonorus StudI/O must now be set up to receive the wordclock transmitted by the 328XD. Open the
Audio System Setup window Panel from within your chosen sequencer, Cubase VST 4.1 on the Macintosh
is used in this example.
Click on the drop down menu and select Optical A as the "Audio Clock Source" , the sample rate will
change to follow the internal frequency of the 328XD.

If the Sonorus Syncplate is not fitted, the Sonorus StudI/O must slave to the wordclock from one of its
ADAT inputs. Set the StudI/O to use the clock source from the ADAT input as required using the method
described above.
If the Sonrous Syncplate is fitted, the StudI/O should slave to the clock on the BNC wordclock input. If the
backplate is fitted then you can also run the Sonorus StudI/O as a master device by setting the "Audio
Clock Source" to Internal. When using this method you must connect a wordclock cable from the
backplate Wordclock Output to the 328XD BNC Wordclock Input. In this instance, ensure you select
‘External: WClock’ from the 328XD Clock Source Select menu to make the console a slave to the Sonorus
StudI/O clock.

Audio Data
The Sonorus StudI/O must now be set up to transmit and receive audio data to and from the 328XD.
Launch the ASIO devices control panel from the previous page. Here you can adjust the bit rate of the
data passing to and from the 328XD. For the highest quality results, select 24-bit, as the 328XD is
capable of transmitting and receiving all 24 bit signals.
Please refer to the Sonorus StudI/O documentation for other system settings.
