Quick Start Guide

By default your iConnectAUDIO4+ is pre-configured to work with Digital Audio
Workstation (DAW) software. All the interface’s audio inputs are routed to the computer
device(s) for recording, not directly to the audio outputs; you won’t hear anything if,
say, you plug in a mic without going through your audio/music software.

Furthermore, all the audio ins and outs are set all the way down, and need to be
raised. This Quick Start Guide will show you how to get sound running in and out of
your interface as simply as possible.

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).

Software

v.1.1

8

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 LEDs then turn red, and the meters go
between green and 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.

v.1.1

9

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:

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.

v.1.1

10

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.

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 (only 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 1&2 have phantom power turned on, and their faders

have been raised:

v.1.1

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.1.1

12

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. This is explained in the Quick Start Guide. 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.

Please use only the supplied iConnectivity 12V/3A (36W) center positive transformer, or
you risk damaging the device.

This adapter operates over a range of 100-240V/50 or 60Hz, so it can be used
internationally with wall plug adapters.

8 USB A Host Jack

This USB 2.0 jack supports up to eight 16-channel MIDI Ports, divided among up to
eight USB MIDI Class-Compliant devices.

Connect, for example, a MIDI keyboard controller via its USB MIDI port instead of using
5-pin DIN cables. Up to 500mA – the USB power standard – is provided, enough to
power a single device. Or connect up to eight USB MIDI devices via a powered USB
hub.

Note: this jack is dedicated to USB MIDI – it’s not a standard USB jack.

9 USB 1 Device Jack

Use the included iConnectivity USB-B to USB-A cable to connect the interface to a Mac
or PC computer, or the included iConnectivity USB-B-to-Lightning cable to connect an
iOS device.

iConfig, the included software program for Mac and Windows provides access to the
set-up and routing features in your iConnectAUDIO4+, and it controls additional
iConnectivity interfaces connected to your system.

The active settings snapshot is stored in the interface’s onboard flash memory; please
see the Device drop-down menu in the following screen shot. It can be copied into the
iConfig software for editing (the “Restore from FLASH” command).

iConfig works the same on Mac and Windows.

Launching iConfig

When you have multiple iConnectivity interfaces connected to your computer, the
Device Selection dialog will appear; simply select the one to be configured. If you have
only the iConnectAUDIO4+, it will be selected automatically in the dialog without
intervention.

Audio Patchbay

This is a routing matrix with source audio busses across the horizontal axis and
destination busses on the vertical axis. Think of it as “from” (audio sources into the
patchbay) and “to” (destinations).

Available Sources and Destinations: USB1 and USB2 (digital Audio Channels from
the two Device Jacks); Analog (the four Analog Ins and four Analog Outs); the Analog
Mixer (which controls the Analog Ins and Outs); and – only when enabled (see four
paragraphs below) – the USB1 and USB2 mixers.

Operation —There is one simple principle to bear in mind when routing audio in the
iConnectAUDIO4+: each Destination bus may have only one Source.

Just as a physical jack doesn’t accommodate two plugs, the Audio Patchbay will not
allow connections that make no sense.

v.1.1

24

Click on the appropriate spot on the matrix to make or sever a routing connection. Click
on any bus’ name in the Source or Destination areas to condense its view (in this case
“Analog Mixer” is condensed, while the Analog outputs above it aren’t):

USB mixer Destination Busses – The USB Mixers seen in the following screen shot
are disabled in the iConnectAUDIO4+’s factory default set-up. Since most DAWs and
other software programs have mixing built in (and the factory default is intended for use
with DAWs), they aren’t needed.

When you do need the USB1 and USB2 Mixer, for example in a live situation, the way
to enable them is to select 2, 4, or 6 (anything other than 0) “Mixes to outputs on USB1
[and/or USB2] domain” under the Mixer Information disclosure triangle in the Audio Info
tab.

v.1.1

Audio Mixer

Audio Mixer overview: The Analog Inputs and Analog Outputs sections – on the

darker grey background – are master faders for the iConnectAUDIO4+’s Analog Ins,
Analog Outs, and Headphones. While the Analog Inputs are “hardwired” directly to their
faders, the Source for each Analog Output channel is selectable from a drop-down
menu.

These Source choices include the Destinations of the three Mixes – A, B, and C — in
the Sub Mix/Bussing section in the middle, shown on a lighter grey background.

In turn, the Sources available to Mix A, B, and C channels depend on the Mixer
Information settings in the Audio Info tab, and also on the way the Audio Patchbay is
configured. Mixes A, B, and C can all have multiple Destinations, and they can share
them.

Audio Mixer operation:

- Click on “EDIT MIX NAME” (as shown above) to rename the A, B, and/or C mixes; the

default names are simply Line Outs 1/2, Line Outs 3/4, and Headphones. These names
appear as SRC (Sources) for the Analog Output channels.

- To select a Source or Destination, click on the underlined white text to get a pop-up

Audio Info

This is the iConnectAUDIO4+’s information and settings screen. As soon as you make a
change, you will have the opportunity to commit your edits to the interface or to cancel:

Audio Information

Number of audio ports (fixed) – 3: two USB Device ports for computer devices, one 4x4
analog port.

Number of buffered audio frames and Sync factor value: as with every device that
processes digital audio, audio goes into a buffer before it is processed, and it takes a
small fraction of a second for audio to fill the buffer as it streams through. This latency is
compensated for with the Sync factor value parameter so that incoming and outgoing
audio is in sync.

The larger the audio frame buffer, the longer this takes, but the lower the strain is on the
device; conversely, smaller buffers lower the processing latency and require more
computing horsepower.

The default settings offer low latency and solid audio performance. However, you may
wish to experiment with faster settings; or if you hear glitches, increase the buffer.

Audio Configuration – the sample rate and bit depth setting. This defaults to the CD-
standard 16-bit/44100Hz setting to ensure compatibility with all iOS software. Higher bit
and (to a lesser degree) sample rates can offer higher sound quality in some
applications, but they use more processing resources.

enable them is to select 2, 4, or 6 (anything other than 0) “Mixes to outputs on USB1
[and/or USB2] domain” as shown below:

Port Information - On the two USB Device Jacks, enable/disable Mac/PC and/or iOS
support; and set the maximum number of input and output channels available (when
they’re enabled in the Mixer Information section).

The number of Analog Jacks is fixed, of course: 6 outputs (4 Analog Out Jacks + 2 for
Headphone Jacks 1&2); and Analog In Jacks 1-4.

Note that the names of the devices can be edited.

MIDI Info

MIDI Information: Summary MIDI information about the iConnectAUDIO4+’s physical

ports, as well as the 29 total 16-channel MIDI Ports available for routing.
Maximum Ports on multi-port USB Devices (default: 4): Multi-port USB MIDI devices

have more than one 16-channel Port. For example, some controllers may have an
additional MIDI In or Out Port available, and modern DAWs can usually access any
number of them. This setting allows up to eight Ports.

Routing between ports on multi-port USB Devices (default: off): Multi-port USB MIDI
devices have more than one 16-channel port.

Running Status on DIN ports (defaults to off) – Running status is a way of reducing the
amount of MIDI data that must be sent. It works by assuming that the first part of the

v.1.1

31

MIDI message - the status byte that identifies what it is (for example a note) – remains
the same until further notice. Running status must be implemented correctly by the
receiving device to work; we recommend enabling it only if you can confirm that this is
the case.

Port Information: MIDI in and out for each physical connection – the 5-pin DIN I/O
jacks, the two USB Device Jacks, and up to eight MIDI devices connected to the USB
Host Jack (if you’re using a powered hub) – has its own line in this section.

Each one can have its Input and Output enabled or disabled, and the names are
editable.

An additional drop-down menu, Reserved, is available for devices connected to the
USB Host jack (remember, these must be USB MIDI Class-Compliant devices). In this
case an M-Audio USB O2 MIDI keyboard is connected; its name appears automatically
to be reserved, which means it will occupy USB Host Jack Port 1 every time it’s
restarted.

However, this works for a single M-Audio USB O2; there would be no way to
differentiate between multiple O2s (or multiples of any device).

MIDI Port Routing

There is a total of 29 16-channel MIDI Ports available to be routed between the
iConnectAUDIO4+’s physical connections. This routing matrix enables this feature

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 to it (for example, a modern
DAW should be able to access every Port as soon as the interface is connected). The
only exception is multiport USB MIDI Devices, which must be enabled in the iConfig’s
MIDI Info tab.

Source Ports are on the left, listed vertically, and Port Routes (destinations) are on the
right. Please check our online video tutorials for specific applications.

MIDI Channel Remap

For each MIDI port, this matrix is for remapping – changing - entire MIDI channels to
different ones, or just various data types (Pitch Bend, Channel Pressure, etc.).

Remap Type (top left) selects whether to modify the input going to or the output coming
from each port.

Port is the familiar list of the16-channel MIDI ports available on the iConnectAUDIO4+:
the USB Device Jacks, USB Host Jack, and 5-pin DIN.

In the screen capture above, incoming MIDI data to USB Device Jack 2 is being
remapped as follows: Pitch Bend data on Channel 3 and Channel Pressure data on
Channel 2 are being changed to Channel 1.

MIDI Controller Data Filter

v.1.1

34

For each MIDI port, this matrix is for filtering (removing from the datastream) any MIDI
controller on any of the 16 MIDI channels.

Filter Type (top left) selects whether to modify the input going to or the output coming
from each port.

Port is the familiar list of the16-channel MIDI ports available on the iConnectAUDIO4+:
the USB Device Jacks, USB Host Jack, and 5-pin DIN.

In the screen capture above, MIDI Continuous Controller 7 (Main Volume) data to USB
Device Jack 1 from the MIDI DIN port is being filtered from Channels 1-6 and 16.

The entire list of 127 MIDI controllers is available for filtering under the drop-down menu
in the Controller ID column.

MIDI Controller Data Remap

For each MIDI port, this matrix is for remapping (converting) any MIDI controller on any
of the 16 MIDI channels to a different one. The entire list of 127 MIDI controllers is
available as a Source and a Destination under the drop-down menu s.

Remap Type (top left) selects whether to modify the input going to or the output coming
from each port.

Port is the familiar list of the16-channel MIDI ports available on the iConnectAUDIO4+:
the USB Device Jacks, USB Host Jack, and 5-pin DIN.

In the screen capture above, MIDI Continuous Controller 7 (Main Volume) data to USB
Device Jack 1 from the MIDI DIN port is being converted to MIDI Continuous Controller
11 (Expression) – but only on MIDI channels 1 through 7.

Troubleshooting

No sound from speakers or headphones connected to the interface

Please check that levels are turned up in the 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.

MIDI is not being received by the expected destination

Please check the routing in the iConfig software MIDI Port Routing tab.

No sound from an iOS device’s speaker/earphones/microphone

The iOS device automatically uses the iConnectAUDIO4+ when it is connected. This
deactivates the built-in speaker, usually the built-in mic, and often the headphones
and/or headset mic when it is plugged into the iOS devices 1/8" TRRS jack.

iOS device’s battery isn’t charging

USB Device Jack 1 will charge an iOS device. USB Device Jack 2 will keep an iOS
device charged or almost charged, or it may charge a smaller iOS device (depending on
usage).

Printer, mouse, computer keyboard, etc. doesn’t work in USB Host Jack

This jack is only for USB MIDI devices.

USB Host Jack won’t power MIDI devices

This USB-standard jack provides enough power for a single MIDI device. Up to eight
additional devices are supported with a powered USB hub only.
