Quick Start Guide
Your iConnectAUDIO4+is not just a standard audio or MIDI interface. Its audio and MIDI
routing capabilities are far more flexible, and it can be configured for many different
applications.
This Quick Start Guide will help you navigate its features and understand the basics as
simply as possible.
BY DEFAULT THE iConnectAUDIO4+COMES CONFIGURED FOR USE WITH A
DAW.
Audio hookup – connecting a Mac, PC, or iOS device
1. Connect a Mac or PC to USB Device Jack 1, using the supplied USB-A to USB-B
cable. *
2. Connect your powered monitors or power amp and speakers to Analog Out Jacks
1&2.
3. Connect the included iConnectivity power supply and plug it into the wall.
* For the purposes of a sound check, you can substitute an iOS device using the Lightning-to-
iConnectivity cable, and then skip to “Using the Interactive Display” a few paragraphs down
(there is no software to configure). But it’s important to install the iConfig software on a
computer (step 2 just below).

v.1.0
8
Software
1. If you’re using a Mac or iOS device, no driver is required. For Windows, please
download the driver and install it. (Installation is straightforward, but for details please
see here.)
2. Download and install the iConfig Software to a Mac or PC. This will ensure that your
interface’s firmware is up to date, and allow access to all its functions and configuration
options.
3. Select the iConnectAUDIO4+as the audio output device in your DAW (or other audio
software).
4. Play some test audio, preferably in a loop. You may not hear anything until you bring
up the output level.
Sound check - adjusting the output level
There are two ways to adjust the output level: directly on the front panel Interactive
Display, or using the iConfig software’s Audio Mixer.
Using the Interactive Display:
1. Touch the region centered around Out on the bottom row, selecting the output level
for adjustment. The LED will turn green, for Signal Level mode, indicating that the LED
meters are displaying the signal level.
You could also touch Out a second time to toggle the display into Gain Set mode, which
is like showing the position of a volume control (the Rotary Knob is continuous, so
otherwise you wouldn’t know where it is). The LED meters then turn red to show the
gain level. An additional touch toggles back to Signal Level mode.
2. Touch the regions centered around 1 or 2 on the top row (they should be linked for
stereo), selecting Analog Outs 1&2 for adjustment. Their LEDs will turn green if you’re in
Signal Level mode, or red if you’re in Gain Set mode.
3. Turn the rotary Knob clockwise to increase the level and counterclockwise to
decrease it.
Using the Audio Mixer:
1. Launch iConfig. If you have other iConnectivity interfaces connected, select the
iConnectAUDIO4+in the Device Selection dialog.
2. Select the Audio Mixer tab. Mix A, the first of the available mixes in the Sub
Mix/Bussing section, should be selected. The mixer should look like the following screen
capture:

v.1.0

3. Bring up the Analog Outputs 1 & 2 fader (they’re linked for stereo). You should now
see three sets of stereo meters moving in the Audio Mixer. If you select Analog Outs
1&2 in Signal Level mode in the Interactive Display, the LED meters on the hardware
will match the onscreen ones.
Adding a second computer device
1. Simply connect the second computer device USB Device Jack 2.
If it’s a Windows computer, install the driver as per the Software instructions above.
With Mac OS X or Windows, select the iConnectAUDIO4+as the audio interface in your
audio software. There’s no software to install or configure in iOS devices.

v.1.0
10
If both computer devices are iOS so there’s no iConfig software with an Audio Mixer,
use the apps’ level controls to balance their relative levels. Otherwise, the second
computer device appears in the Audio Mixer channel strip to the right of the first one;
iConfig is already set up.
Recording audio
1. The four Analog In Jacks on the front panel are routed to the first four inputs of both
computer devices, i.e. to the USB1 and USB2 Device Jacks. DAWs and iOS devices will
see them as available inputs to tracks for recording.
All four combo Analog In jacks accept mics; Inputs 1&2 accept unbalanced Hi-Z
instruments on ¼" plugs; and Inputs 3&4 accept balanced line signals on ¼" TRS plugs.
2. Enable +48V phantom power for condenser mics on any or all four Analog In jacks,
and adjust the input levels. This can be done with the Interactive Display, or in the
iConfig Analog Mixer.
- Here Analog Input channels have are phantom power turned on and their faders have
been raised:

v.1.0
11
- To enable phantom power for Analog Inputs 1&2 in Interactive Display, simply touch
the 48V touch zone on the bottom row, then 1 and 2 on the top row.
- To adjust the gain levels for Analog Inputs 1&2 on the Interactive Display, touch In on
the bottom row, and 1 and/or 2 on the top row (depending on whether they’re
independent sources or a stereo pair). Then use the Rotary Knob to adjust the levels.
Subsequent touches of In on the bottom row toggle between Gain Set and Signal Level
modes (as discussed above when we set the output level).
MIDI
The iConnectAUDIO4+has one input/output pair of 5-pin MIDI DIN jacks, a single USB
Host jack (for MIDI devices with USB connection instead of 5-pin), and MIDI is routed to
and from both computer devices connected to the USB Device jacks.
Use a powered USB hub to connect up to eight USB MIDI devices to the USB Host jack,
otherwise it supplies enough power for a single MIDI device plugged in directly.
There are 29 16-channel MIDI Ports available to be routed between those physical
connections – 464 MIDI channels.
By default, every possible MIDI Port is routed from every device to every other device; if
a device supports multiple Ports, they’re all accessible. The only exception is multiport
USB MIDI Devices, which must be enabled in the iConfig’s MIDI Info tab.

v.1.0

IMPORTANT NOTES
• No additional drivers are required for Mac or iOS, Windows driver available here. Set-
up instructions here.
• No Mac or iOS drivers needed. The iConnectAUDIO4+is USB class-compliant, so it’s
recognized automatically by Mac OS X and iOS for applications to pass audio and MIDI
as soon as you connect it to either of the unit’s two Device ports.
• IF YOU HEAR NOTHING FROM YOUR SPEAKERS OR HEADPHONES: please
check that levels are turned up, either using the Interactive Touch Display or Audio
Mixer tab in the iConfig software. In addition, check that the output source you’re
monitoring is routed correctly in the Audio Patchbay tab.
• The default 16-bit/44.1kHz setting ensures compatibility with iOS software that doesn’t
operate at higher rates, but it can be changed up to 24-bit/96kHz in the iConfig
software’s Audio Info tab.

Interactive Display
The iConnectAUDIO4+’s Interactive Display makes it simple to view and adjust analog
input and output levels, enable/disable 48V phantom power for condenser mics, and
perform various utility functions without using the iConfig software.
It consists of a capacitance touch panel with eight touch zones and dual 8-stage LED
meters; and a Rotary Control Knob that also performs various functions when it’s
pushed/double-pushed.
Viewing Modes
There are two viewing modes. Successive touches of a bottom row touch zone (except
48V) toggles between the two.
- Signal Level mode, indicated by a green bottom row LED. The LED meters display
VU (the signal level).
- Gain Set mode, indicated by a red bottom row LED. This is like showing the position
of a volume control (the Rotary Knob is continuous, so otherwise you wouldn’t know
where it is).
The 48V touch zone has no effect on the viewing mode, since it’s an on/off function
rather than a level setting.
Basic Operation
1. Touch the region centered around one of the four functions on the bottom row to
select it: 48V, In, Out, or Phones.
2. Touch numbers 1 through 4 on the top row to select that analog input or output for
adjustment (or to turn 48V phantom power on/off).
3. Turn the Rotary Knob to adjust the In, Out, or Phones level.
Example: adjust the level of Analog Outs 1&2, which are connected to your powered
monitors.
