To conﬁgure digital formats and sample rate

conversion:

1 Click on the Digital tab and select Input For-

mat (AES/EBU, ADAT, or TDIF).

2 Enable real-time Sample Rate Conversion by

selecting channel pairs (1–2, 3–4, 5–6, 7–8) in

the SR Conversion box on the Digital tab.

To conﬁgure additional interfaces:

■ Repeat the above steps for additional HD-se-

ries I/O in the Peripherals list. To conﬁgure the

Main tab of a secondary HD peripheral attached

to a primary HD I/O, you must ﬁrst choose the

I/O in the Peripherals list.

The following example shows how to conﬁgure an

HD system with one 192 Digital I/O and one

96 I/O in the Hardware Setup dialog:

1 From the Peripherals list, choose the

192 Digital I/O (which must be your primary

I/O for any sample rates higher than 96 kHz). By

default, the Main tab will be selected, and op-

tions and controls for the selected I/O will be

available. The expansion interface connected to

the primary I/O will appear below it in the Pe-

ripherals column.

2 In the Main page, ensure that Expansion I/O is

selected under Port Settings.This is the default.

3 From the Peripherals list, select your second-

ary I/O (in this case, the 96 I/O).

4 Conﬁgure the Main page and other settings

and options for the secondary peripheral.

sult the Getting Started with HD Guide.

At session sample rates above 48 kHz, sam-

ple rate conversion for the TDIF and Optical

(ADAT) inputs on the Digital I/O card is

automatically enabled on all eight inputs of

the selected format.
