1. Headphone Outputs – Connect your headphones to these
outputs. The first headphone output always mirrors the
analog 1/2 output pair. The second headphone output is
assignable in software.
2. Main outputs (8 outputs on IO|26; 2 outputs on IO|14)
– Use ¼," "TRS" cables to connect these outputs to the
balanced inputs of your powered speakers or power amplifier.
The IO|26 (shown above) has 8 outputs. The IO|14 has 2
outputs. If you are using the IO|26 and wish to connect
additional speakers, headphone amplifiers or hardware
processors, connect them to outputs 3 through 8.
3. Phono input (IO|26 only) – Connect your turntable to this
input.
If your turntable has a grounding cable, attach it to the
grounding screw to the upper right of the phono inputs.
This grounding will minimize humming and buzzing.
4. ADAT Lightpipe Inputs –Use ADAT-compatible optical
cables to connect to these inputs.
5. S/PDIF Connectors – Connect S/PDIF-enabled digital
devices using coaxial, RCA-terminated cables.
6. MIDI Connectors – Connect your keyboards, sound
modules, or other MIDI devices using 5-pin MIDI cables.
7. FireWire Connectors – Connect one of these plugs to your
computer's FireWire port. You can use the other jack to
connect additional FireWire devices (such as hard drives) to
your computer.
8. Power Connector – Use the supplied AC adapter if your
computer does not provide sufficient Firewire bus power to
power the IO|14/26 or if you want to preserve battery
power.
9. Kensington Security Slot – This locking mechanism allows
you to secure your IO|14/26 to a desk or some other heavy
object using an optional third-party locking device.

The IO|14/26's outputs are
"impedance balanced." This
wiring method provides all of
the benefits of "fully
balanced" wiring when the
outputs are connected to
balanced gear. Furthermore,
impedance balancing, unlike
other balancing methods,
allows for trouble-free
connection to unbalanced
devices.
If you connect an ADAT or
S/PDIF input device (or
both), you will need to select
one of them as the "clock
master" in the IO's control
panel.
The device you select as the
clock master will determine
the IO's clock rate and will
be responsible for keeping all
of the digital signals
synchronized.
If an AC adapter is attached,
the IO|14/26 will use it.
FireWire bus power is only
used if no AC power is
available.
