• WARNING: Only put on your headphones or turn on your speakers AFTER turning on the EIE Pro.
• When recording a guitar or bass with an active pickup, set the EIE Pro's GUITAR / MIC/LINE SWITCH to "MIC/LINE." If your instrument uses a passive pickup, set the switch to "GUITAR."
• To reduce electrical hum at high gain settings, keep the EIE Pro's power supply away from your guitar cable and the EIE Pro's channel inputs.

AUDIO SETUP

EIE Pro can be used with any digital audio workstation or recording software that supports USB audio. To enable your EIE Pro to send and receive audio to and from your computer, follow the instructions below for your computer's operating system:

Be sure your audio software program is set up to receive audio via the EIE Pro. This can usually be done in your software's "Preferences" or "Device Setup." Please consult your software manual for more information.

FRONT PANEL FEATURES

1. MIC/LINE / GUITAR INPUT – Connect a microphone, line-level device or guitar to this input with an XLR or 1/4" TRS cable.

2. GAIN – Adjusts the input's gain level.

3. LEVEL MIC/LINE / GUITAR SWITCH

4. When the switch is in the "MIC/LINE" position, the channel will accept mic or line-level signals. When this switch is in the "GUITAR" position, the channel will serve as a high-impedance input for connecting guitar or bass instruments.

5. PHANTOM POWER SWITCH – This switch activates and deactivates phantom power for each channel pair (Channels 1 and 2 and/or Channels 3 and 4). When activated, phantom power supplies +48V to both XLR mic inputs. Please note that most dynamic microphones do not require phantom power, while most condenser microphones do. Consult your microphone's documentation to find out whether it needs phantom power.

6. VU METERS – These meters display the volume level of the channel pairs, depending on the setting of the METER SELECTION CHANNEL SWITCH. These meters will be lit whenever EIE Pro is powered on. The red light indicates the signal is distorting or "clipping." If the signal is regularly clipping, reduce the volume of the mix and/or individual channels.

7. METER SELECTION CHANNEL SWITCH – This switch selects which pair of channels the left and right VU METERS will display (respectively) – Channels 1 and 2 ("1/2") or Channels 3 and 4 ("3/4").

8. METER SELECTION MONITOR SWITCH – This switch selects whether the VU METERS will display the volume level at the inputs ("IN") or outputs ("OUT").

9. MASTER LEVEL – Adjusts the output volume of the AUDIO OUTPUTS 1 and 2.

10. MONO / STEREO – Adjusts the master mix for mono or stereo operation.

11. HEADPHONE - Connect a set of 1/4" TRS headphones to this output.

12. HEADPHONE VOLUME – Adjusts the output volume of the PHONES output.

13. HEADPHONE SELECT SWITCH – This switch selects what channels are sent out the HEADPHONE output – Channels 1 and 2 ("1/2"), Channels 3 and 4 ("3/4"), or all channels ("ALL").

14. MONITOR MIX – Blend in any amount of zero-latency signal from your inputs ("IN") with the output of your computer ("OUT").

REAR PANEL FEATURES

1. DC INPUT – Connect the included power adapter (6V, 3A, center pin-positive) here, then connect the adapter to wall power.

2. POWER SWITCH – Turns the EIE Pro on and off.

3. USB MIDI - This connection will allow you to send MIDI information to/from a computer. Use a USB cable to connect the EIE Pro to a computer. EIE Pro requires a USB 2.0 connection.

4. USB HUB OUTPUTS – You can connect additional USB devices (controllers, hard drives, etc.) to these powered USB ports. In addition to being an audio interface, these ports allow EIE Pro to function as a powered USB hub.

5. AUDIO INPUTS (INSERTS) – You can use standard 1/4" TRS insert cables to connect external processors (such as compressors, limiters, external EQ units, etc.) to these jacks. The signal will be taken after the channel's gain control and returned before the channel's USB audio is sent to the computer.

6. AUDIO OUTPUTS – Use standard 1/4" TRS cables to connect these outputs to monitors, an amplifier system, etc. The level of AUDIO OUTPUTS 1 and 2 are controlled by the MASTER LEVEL knob. The level of AUDIO OUTPUTS 3 and 4 are always at full volume.

7. MIDI OUT - Use a standard five-pin MIDI cable to connect this output to the MIDI IN of an external MIDI device.

8. MIDI IN – Use a standard five-pin MIDI cable to connect this input to the MIDI OUT of an external MIDI device.
