Install the drivers onto your computer BEFORE you connect your IO|14/26

Important: Download and install the drivers from—orinsert the software CD into your computer’s CDdrive—BEFORE you plug your IO|14/26 into your computer for the first time.


Thank you for purchasing the Alesis IO FireWire audio interface!

You could say Alesis knows a thing or two about recording. Countless artists, engineers, and producers have relied on our digital recorders since the introduction of the original “Blackface” ADAT in 1991. Some publications have even claimed that our ADAT recorders started the “home studio revolution” back in the 1990s. We’re proud that our line of affordable tools has made professional-qualityrecording possible for millions of people around the world.

The IO series FireWire interfaces are the next step in Alesis recording technology. Once you work with the IO|14/26, we’re confident you’ll appreciate the outstanding sound quality, superior construction, and attention to detail.

We’re continually delighted by the recordings that have been captured with our products. We hope that your IO|14/26 will be there to inspire and capture your finest performances.

1.Inputs – Connect either XLR or ¼” cables to the inputs.

2.Inserts – Place additional equipment (like compressors, equalizers, etc.) into your signal path using “insert” cables.

3.Mic/Line or Guitar Switch (Channels 1-2only)– Switch to a high-impedance circuit to record electric guitars/basses.

4.Gain Knobs – Set the preamplifier gain level.

5.Monitor Blend Knob – This knob controls the amount of direct signal (from the analog and digital inputs) that gets blended in to outputs 1/2. This direct signal monitoring bypasses the computer forlag-freelistening while tracking.

6.Metering Section 5-segment“ladder” meters show the precise digital input signal for each analog channel.

Status lights indicate Firewire connection to the computer, current sample rate, and ADAT, S/PDIF, and MIDI activity.

Stereo output meters show the levels for outputs 1/2.

7.Phones 1&2 Volume – The IO|14/26 has two separate headphone outputs.

8.Main Level – This knob sets the output level of channels 1/2.

9.Mic/Line or Phono Switch (IO|26 only) –If you want to connect a turntable to your IO|26, use the RCA “phono” inputs (on the rear of the unit) and engage this switch.

10.Phantom Power – These switches let you supply +48v “Phantom Power” to condenser microphones that require power. Each button engages/disengages phantom power for a pair of inputs (i.e., channels1-2,3-4,5-6,and7-8).

The combo jack inputs

The XLR input “expects” to see a microphone and delivers between 6.8dB and 50dB of gain, depending on the position of the gain knob.

The ¼” input “expects” to see either a line input or an electric guitar or bass, depending on the setting of the Mic/Line/Guitar switch.

In the Line position, the input provides between -15.4dBand 27.8dB of gain. This

Phantom power is only necessary for condenser microphones. Dynamic microphones do not need power to work correctly. Check your microphone’s manual to find out if it needs phantom power.

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 – ConnectS/PDIF-enableddigital devices using coaxial,RCA-terminatedcables.

6.MIDI Connectors – Connect your keyboards, sound modules, or other MIDI devices using5-pinMIDI 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-freeconnection 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.


Install the software/drivers first

Important: Download and install the drivers from insert the software CD into your computer’s CDdrive—BEFOREyou plug your IO|14/26 into your computer for the first time.

Important: Follow these steps BEFORE you plug your IO|14/26 into your computer for the first time.

Begin by running the Alesis installer(s). These programs (there may be one or more than one) will install three very important components onto your computer:

Drivers. These are the system components that allow Microsoft Windows or Mac OSX to identify and interact with your IO|14/26. You do not interact with the drivers directly, but they must be installed on your computer for the IO|14/26 to work.

Control Panel. The control panel allows you to set sample rates, clock sources, buffer sizes, and other settings.

Hardware Direct Monitoring Panel. This application lets you route the IO|14/26’s inputs directly to its outputs for a minimum of latency (delay) when recording.

The Hardware Direct Monitoring Panel also allows you to change Headphone2 and S/PDIF output assignments.

Windows users:

For each of the several installations that occur, click “Continue Anyway” if Windows warns you that the drivers have not passed Microsoft Logo Certification.

If you have access to the Internet, check for the very latest software updates. The updates posted there are guaranteed to be the most current, best software versions available.

Windows Logo Certification warning.

Ignore this warning by clicking “Continue Anyway.”


Install Cubase LE (optional)

If you are interested in using Cubase LE as your multitrack Digital Audio Workstation, install it from the CD now.

Connect your IO|14/26

Now, connect your IO|14/26 to your computer using a Firewire cable. Watch for one of the lights on the unit to turn on within a few seconds. If a light does not turn on—orif you are using a notebook computer with a smallfour-pinFirewire connector— plug in the external AC adapter.

Windows users:

Windows will recognize the IO|14/26 and start the Found New Hardware wizard. The installation process will automatically install these drivers one by one.

When you are prompted whether to install the drivers automatically or search for a specific location, choose to install them automatically.

If you are asked whether you want to connect to the Internet to check for the latest driver, choose not to.

Let the installer continue installing the various sets of drivers until you see a message stating, “Your new hardware is installed and ready to use.” Do not cancel any of the installations, as they are all required for proper operation.

Begin using your IO|14/26

You are now ready to begin using your IO|14/26.
