1 Hardware Overview Rear Panel You'll find the following on the rear of your IO|14/26: 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. If your speakers or amplifier only provide unbalanced inputs, use unbalanced ("TS") cables. 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 - These optical digital inputs can accommodate a wide variety of ADAT-enabled gear. The IO|14 has one ADAT input whereas the IO|26 (shown above) has two ADAT inputs. Use ADAT-compatible optical cables to connect to these inputs. 5. S/PDIF Connectors - Connect S/PDIF-enabled digital devices (such as the Alesis Masterlink, CD players, DAT machines, MiniDisc Recorders, etc.) to your IO|14/26 using coaxial, RCA-terminated cables. 6. MIDI Connectors - Connect your keyboards, sound modules, or other MIDI devices to your IO|14/26 using 5pin MIDI cables. Remember to chain the OUTs of each device to the INs of other devices. The IO14/26'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. Therefore, if you turn this device off, you will need to select another clok master in the control panel. 12

Hardware Overview
12
Rear Panel
You’ll find the following on the rear of your IO|14/26:
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.
If your speakers or amplifier only provide unbalanced inputs,
use unbalanced (“TS”) cables.
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
– These optical digital inputs
can accommodate a wide variety of ADAT-enabled gear.
The IO|14 has one ADAT input whereas the IO|26
(shown above) has two ADAT inputs.
Use ADAT-compatible optical cables to connect to these
inputs.
5.
S/PDIF Connectors
– Connect S/PDIF-enabled digital
devices (such as the Alesis Masterlink, CD players, DAT
machines, MiniDisc Recorders, etc.) to your IO|14/26 using
coaxial, RCA-terminated cables.
6.
MIDI Connectors
– Connect your keyboards, sound
modules, or other MIDI devices to your IO|14/26 using 5-
pin MIDI cables.
Remember to chain the OUTs of each
device to the INs of other devices.
The IO14/26’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.
Therefore, if
you turn this device off, you
will need to select another
clok master in the control
panel.
