Evo 4 Operation
Overview
The Evo 4 Loopback Kit is designed to make it easy to record computer-based teleconferences in
SoniClear with high audio quality. It will work with any conferencing software, such as Zoom, WebEx,
or Teams. It also works with softphone programs, such as 8x8 Work, Vonage, Ring Central, and Avaya.
The Evo 4 must be installed correctly before use. See the section below, “Evo 4 Loopback Kit
Installation”. After installation, the Evo 4 interface will turn on automatically when the computer is
started, making it immediately ready for teleconferencing and for recording in SoniClear.
Using Microphone and Headphone
The kit includes a microphone, a monitor headphone, and the black Evo 4 interface control box for
connecting the microphone and headphone to the computer.
Place the microphone so that it is close to where you are sitting without being in the way of your work.
The microphone has a very directional pickup pattern, so it does not need to be right in front of your
mouth. You will be heard clearly without needing to lean in to the microphone.
All of the features of the Evo 4 are adjusted using the buttons and single large knob on the top of the
control box:
You will normally only need to use the volume knob to adjust the playback level on the headphones.
When starting your conference, press the headphone level button in the lower right corner. Then turn
the large knob to get the desired listening level.
Additional Usage Notes
1. In normal use only the control button for adjusting the headphone level will need to be used. The
other buttons on the Evo 4 should not be pressed. For example, the “48V” button in the upper left
corner should always be on (illuminated red). Pressing the control buttons may result in the
settings being incorrect. See “Resetting All Controls” below for fixing this problem.
2. If you have trouble hearing the teleconference participants, you may need to adjust the
monitoring balance. This allows you to have a comfortable level for hearing the participants and
yourself. This adjustment also controls the volume in the headphones when using the computer to
play audio to the teleconference participants. Press the monitor button in the lower right
corner of the Evo 4. Turning the volume knob counter clockwise will increase the volume of your
microphone (and the playback audio from the computer). Turn the volume knob clockwise to
increase the proportion of sound from the teleconference participants. Normally setting the
monitor level to the middle (12 O’clock position) will give a good balance of the signals.
3. If the participants in the teleconference have trouble hearing you because the volume is too low or
too high, the microphone level can be adjusted by pressing #1 microphone button and then
turn the large knob to get the proper volume. After adjusting the microphone level, you should
press the headphone level button again (to avoid accidently changing the microphone level).
4. The supplied single-earpiece headphone can be replaced with any type of headphone that you
prefer for listening to the teleconference, using the included ¼” to 3.5mm headphone adapter.
Resetting All Controls
If for some reason any of the required Evo 4 settings are accidentally changed, the default settings can be
restored with the following steps:
Left click on in the “Windows System Tray”. This is the little up arrow icon in the lower right corner of
the computer screen:
Then right click on the Evo control icon:
Select “Show EVO Control” to display the Evo 4 control panel:
Click on the File/Open pulldown menu selection to open the Load Mixer window:
Select the SoniClear setting shown there and click the Load button to reset the Evo 4 to the default values.
Note that it may appear that the Load button is disabled when it is in fact working. Hovering the mouse
over that button will cause it light up so that it can be clicked.
Evo 4 Loopback Kit Installation
Evo 4 Hardware Installation
Overview
The Evo 4 Loopback Kit includes the parts needed for recording Windows communication software, such
as a Zoom online conference IP telephone “softphone”. Included in the kit are:
-Audient Evo 4 USB audio interface mixer (2 channels)
-Samson C02 microphone and desk stand
-Computer audio output cable
-Monitoring headphone with ¼” adapter
-Mono monitoring headphone
USB Interface
The Audient Evo 4 interface requires a USB 2.0 or USB 3.0 connection. The Evo 4 should be connected
directly to a port on the computer or a manufacturer supplied docking station. Connecting it to a USB hub
may result in unreliable operation.
Power Connection
The Evo 4 is powered from the USB Port and does not require the use of a power adapter.
Audio Connections
The included microphone is connected to the Evo 4 microphone input #1 using the included standard
XLR microphone cable. This microphone is used to record the local participant in SoniClear and can also
be configured as the microphone for the communications software.
The speaker or headphone output of the computer is connected to the Evo 4 microphone input #2 using
the ¼” to 3.5 mm audio cable included in the kit. Note that this cable is plugged into the ¼” part of the
“combo” input connector on the back of the Evo 4.
The supplied monitoring headphone is plugged into the front of the Evo 4 adapter using the supplied ¼”
adapter. Any standard headphone can be used for monitoring, as well.
Evo 4 Software Installation
Drivers
The Evo 4 requires manual installation of product-specific drivers. This includes custom control panel
software for configuring the device. As of the last update to this manual, the download link for the driver
installer was: https://evo.audio/evo-support/general/driver-installation/. Only install software downloaded
from the official Evo 4 or Audient website. Do not install software from a third-party service.
Loading and Saving Presets
The Evo 4 requires special configuration for compatibility with SoniClear. A default set of presets for use
with SoniClear are available for download. After installing these presets, the Evo 4 needs to be adjusted
for use with the teleconferencing software. Once all of the levels have been properly adjusted, the settings
need to be saved to a customized preset.
The file providing the needed presets is available for download from the SoniClear website:
https://download.soniclear.com/evo-presets.
After downloading the preset file, right click on the Evo 4 control panel icon in system tray and select
“Show Evo Control”:
This will display the mixer with the default settings provided with the drivers:
Click on the File/Open pulldown menu selection. This opens the Load Mixer window:
