The three additional USB ports allow the EIE Pro to function as a hub as well, bridging other MIDI controllers and hard-drives to the computer. The EIE Pro sends and receives four audio channels on a single USB cable for simple, universal interface to a computer. 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. For remote tracking and alternative playback, the EIE Pro has a 1/4” TRS headphone output. Both pairs of outputs can be monitored visually with the high-quality, analog VU meters providing classic features with modern style. You can monitor sessions on multiple sets of studio monitors using the four ¼” balanced outputs, which are also Nickel-plated.
Individual ¼” Nickel-plated jacks found on the back of EIE Pro provide you with channel inserts for processing audio signals externally. The EIE Pro features four discrete-design preamplifiers with 48V phantom power for use with virtually any microphone. Each channel of the EIE Pro has a XLR-¼” combo jack, dedicated sturdy, gain-pots and Mic/Line/Guitar switches.
