Technical Specifications

Audio playback or recording stutters or

drops out

Again, work with the buffer settings in the ASIO control panel or

through your WDM application’s audio setup options in order to

find the most reliable setting.

Many audio applications include advanced setting dialog boxes

where pre-fetch and other parameters can be set. Explore those

options.

Audio echoes during recording

This is probably happening because your “delayed” signal (the

signal that passes through your computer’s audio application back

out to your speakers) is mixing with your “hardware direct

monitoring” mix.

To resolve this problem, either disable your audio software’s “input

monitor” option or, if you want to monitor through your software,

mute the appropriate input channel(s) on the Alesis Hardware

Direct Monitoring application. For more information on the

HDM application, see page 35.

Problems with notebook computer audio

recording

Notebook computer recording problems (hum, dropouts, etc.) can

generally be diagnosed and solved in one of the following ways:

1. The power from your notebook computer may be marginally

insufficient to guarantee stable performance. Use the included

AC adapter whenever you connect your IO|14/26 to a

notebook computer or small form factor computer (such as a

Mac Mini computer or a computer built around a microATX

motherboard).

2. The notebook computer may be introducing a ground loop

problem. To test for this, unplug your notebook’s power

adapter and run on battery power. If this solves your problem,

consider using a three-to-two prong "ground lifter" between

your computer and your AC power source. Be sure to observe

all necessary safety precautions.

3. If your computer has a mini Firewire jack, be suspicious

of your four-to-six pin Firewire cable. Many poorly

constructed cables cause problems. Try using a respected,

brand-name cable.

4. Again, if your computer has a mini Firewire jack,

consider using a six-pin Firewire PCMCIA card or ExpressCard

to bypass the built-in firewire connection altogether.

Help on the web

Most major recording

programs are supported by

lively user forums. The odds

are that, if you’re having

problems, someone who posts

at these forums has already

experienced them and found

solutions.

Don’t be shy about visiting

these forums and posting

your questions.
