Akai Pro EIE Electromusic Interface Expander

All your music gear in perfect harmony. The EIE I/O is a tabletop USB audio interface perfectly tailored for your project and portable studio setups. This four-in, four-out (4x4) device enables you on Mac and PC-based systems to record up to 24-bit resolution into virtually any DAW, recording or performance software. The EIE I/O also houses three convenient USB inputs, in addition to its main USB port, enabling you to connect controllers, hard drives or any other peripheral when native ports on a computer may be limited. The compact recording interface contains high-quality components including nickel-plated input jacks, analog-style VU meters and a rugged aluminum casing for a powerful, professional, portable audio solution.

Each channel of the EIE I/O has a XLR-¼” combo jack, dedicated sturdy, gain-pots and Mic/Line/Guitar switches. The EIE I/O features four discrete-design preamplifiers with 48V phantom power for use with virtually any microphone. Individual ¼” Nickel-plated jacks found on the back of EIE I/O provide you with channel inserts for processing audio signals externally. You can monitor sessions on multiple sets of studio monitors using the four ¼” balanced outputs, which are also Nickel-plated. Both pairs of outputs can be monitored visually with the high-quality, analog VU meters providing classic features with modern style. For remote tracking and alternative playback, the EIE I/O has a 1/4” TRS headphone output. High quality analog-to-digital and digital-to-analog converters ensure that every detail of your session or performance gets captured and played back faithfully.

The EIE I/O sends and receives four audio channels on a single USB cable for simple, universal interface to a computer. The three additional USB ports allow EIE I/O to function as a hub as well, bridging other MIDI controllers and hard-drives to the computer. The USB interface is class compliant for plug-and-play operation with Mac OS X and Windows XP, Vista and 7. The EIE I/O features traditional MIDI In and Out jacks for playing and controlling software with keyboard and pad controllers, workstations, and other MIDI-compatible instruments.

Digital Specifications

Computer Connection
The computer connections for the audio interface to transmit data and/or audio.
Sample Rate
Sample rate defines the number of samples per second (or per other unit) taken from a continuous signal to make a discrete signal.
Bit Depth
Bit depth represents the bits of information that are recorded for each sample. Bit depth directly corresponds to the resolution of each sample in a set of digital audio data. Common examples of bit depth include 16-bit CD audio, and DVD-Audio that can support up to 24-bit audio.

Audio Specifications

Nominal Input Level
The nominal level is the level at which the device was designed to operate for the greatest dynamic range.
THD (Total Harmonic Distortion)
The amount of change in harmonic content of the signal as it is amplified. A lower figure indicates less change and a more accurate amp. THD below 0.10% is inaudible.
Output Impedance
This is the amount of impedance that the microphone allows.
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).

System Requirements

General Specifications

Display Type
The type of display on your receiver refers to the monitor that is used to display the source information such as song names, radio stations, or track times.

Dot-Matrix Text Display: A simple display which uses dots in specific illuminated color(s) to light up and form letters or numbers that are displayed on the receiver.

Graphic or Motion Display: Typically found in mid to high-end receivers and give your text information and receiver more life by adding motion, backgrounds, or multiple colors to your display. There are types of graphic displays such as 3D Graphic, Motion, and OEL (Organic Electroluminescent) displays. They can range from one color to full color displays and typically allow you to select from one of many built-in animations, background images, screensavers or other graphics to enhance your experience and add an extra bit of personality to your system. Some units also come with software that allow you to load your own customizable pictures or animations.

LCD Monitor Display: Can be as small as 2" or as large as 10". Some LCD displays are motorized for angle adjustment. LCD monitors display full motion video playback as well as your standard text such as track status, radio station information and more depending on the receiver's features.
