96 I/O Guide

Setting Operating Levels

There are specific windows within the Hardware
Setup dialog in which to make I/O settings spe-
cific to your 96 I/O. These include setting input
and output operating levels.

Ch4 dBu or –10 dBV
Operating Levels

It is important that you determine which line
level is appropriate for your studio. In +4 dBu
operating mode, the 96 I/O is a 24-bit digital
audio device capable of producing audio signals
up to + 18 dBu 4 dBu input/output. The
default headroom value is 14 dB. This translates
to a maximum output of + 18 dBu.

Check the owner’s manual for your mixer,
power amplifier or effects processor to see if it
can handle this load. If the other devices in your
studio cannot handle this load, consider lower-
ing the headroom value of Pro Tools.

About Input Operating Levels

As with Output levels, check the owner’s man-
ual for your mixer, power amplifier or effects
processor to see if it operates more comfortably
at line level, in which case consider setting the
96 I/O to operate at –10 dBV line levels.

Consider the following when connecting a
mixer:

◆

If your mixer cannot handle more than 1.5V

(RMS) inputs at +4 dBu, then you should set the
96 I/O to operate at –10 dBV line level.

◆

If your mixer can handle up to 6.15V (RMS)

inputs, or has pads or attenuators on its inputs,
then you can use the +4 dBu setting on the
96 I/O.

◆

96 I/O is calibrated for 14 dB headroom at the

+4 dBu setting.

Most manuals contain device input specifica-
tions, including whether or not there are pads or
attenuators. Consult the manufacturer’s docu-
mentation for your mixer or power amplifier for
further information.

Selecting Analog Input Operating
Levels

If you want to switch the input levels of the
96 I/O from +4 dBu to –10 dBV, you can access
these parameters, on a channel-by-channel ba-
sis, in the Hardware Setup dialog.

To Set Input Operating Levels:

1

Launch Pro Tools.

2

Choose Setups > Hardware Setup in Pro Tools.
