ble, unbalanced, two-conductor, phono
(RCA) jacks.
Because input channels 1–2 of the
1622 I/O are software selectable between
analog or digital format, input to these two
digital channels is disabled when analog
input is chosen in the Hardware Setup dia-
log in Pro Tools. Output is continuously
active on the S/PDIF output jack, even if
the 1622 I/O input selector is set to Analog
in the Hardware Setup dialog. To avoid RF
interference, use 75-ohm coaxial cable for
S/PDIF transfers and do not exceed a cable
length of 10 meters.
5. 60-pin Interface Connector
This 60-pin connector is used to connect
the 1622 I/O to a MIX or d24 card. The ap-
propriate interface cable is supplied with
the 1622 I/O.
6. Power Input
This connector accepts a standard AC
power cable. The 1622 I/O is auto power
selecting (100 V–240 V), and will automat-
ically work with a standard modular cable
to connect to AC power receptacles in any
country.
Making Signal Connections
to the 1622 I/O Interface
Depending on how you plan to use
Pro Tools, the way you connect the
1622 I/O to your studio will vary.
Adjusting 1622 I/O Gain Levels
The 1622 I/O input levels are adjustable
through the Pro Tools software to accom-
modate a variety of equipment output lev-
els. For optimum fidelity and sig-
nal-to-noise performance, you should
adjust these inputs according to the de-
vices that you have connected to them.
After you have set up, configured and
launched Pro Tools, refer to the instruc-
tions below for adjusting input gain levels
for the 1622 I/O.
For best signal-to-noise performance, set
the 1622 I/O input gain to +4 dBu when you
are recording devices that provide this output
level.
To adjust input level gain on the 1622 I/O:
Connect the instrument or device to the
1
1622 I/O.
In Pro Tools, choose Setups > Hardware.
2
Click Other Options.
3
Set the input trim slider to match the
4
output level of the connected instrument.
(Refer to the manufacturer's documenta-
tion for operational details.) If you do not
know the output level of the device, use
the default input trim level, then fine tune
the input level gain using the procedure
below.
Select the desired output gain level,
5
+4 dBu or –10 dBV.
Click Done.

To fine tune the input level gain:
Create an auxiliary input track. This can
1
be either mono or stereo depending on the
device you are monitoring.
