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 – 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.
4.
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.
5.
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 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.
6.
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").
7.
METER SELECTION MONITOR SWITCH – This switch selects whether the VU METERS will display
the volume level at the inputs ("IN") or outputs ("OUT").
8.
MASTER LEVEL – Adjusts the output volume of the AUDIO OUTPUTS 1 and 2.
9.
MONO / STEREO – Adjusts the master mix for mono or stereo operation.
10.
HEADPHONE – Connect a set of 1/4" TRS headphones to this output.
11.
HEADPHONE VOLUME – Adjusts the output volume of the PHONES output.
12.
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").
13.
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 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 to a computer.
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 to function as a powered USB hub.
5.
AUDIO INPUTS (INSERTS) – You can use standard 1/4" TRS 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.
