Installation and setup

For iOS users: when working with iOS devices and +48V phantom power is required, iRig Stream Pro needs

to be powered with two AA batteries. See specifications about battery life. Insert the included AA batteries in

the battery compartment on the bottom side of iRig Stream Pro. If you want to stream for a long time, you can
connect the DC In port on iRig Stream Pro to the optional PSU (iRig PSU 3A). In this case the iRig Stream Pro

will also charge the connected lightning iOS device.

For MAC/PC and Android users: when connected to an USB class compliant host, iRig Stream Pro will be
USB powered, ONLY if the host device is capable of providing enough current. When connected to Android
devices and phantom power is required, we recommend that you use the optional PSU to avoid running out of

battery life.

3. In order to monitor the incoming audio with apps and software that do not allow for audio input monitoring,
a direct monitoring switch is present. When this switch is set to on the input signal is mixed with the output

signal from your audio software and routed directly to the headphone outputs. This lets you hear the “live”

inputs without latency. If a “phasing” effect is present, you can disable the input monitoring from your
recording app. For more details about its monitoring function, refer to the documentation for the audio

software.

4. Connect any line level signal to the front RCA stereo input. To adjust the volume of the device connected to

these connectors, use both the volume controls of the device and the numbered thumbwheel “RCA” on side

of iRig Stream Pro.

Repeat the steps above to change operation mode per your needs.

HINT: make sure to change the operation mode (stereo or multichannel) before opening your recording/
streaming App. This because each time you’ll change the operation mode, the interface will restart itself.

Multichannel operations

In order to use the multichannel functionality, a DAW or an App that supports multitrack recording is needed. If
you’re using an App make sure to set it to run in Background, this allows you to use it while you’re using other
Apps (such as streaming Apps).

The multichannel operation is particularly useful when you want to stream a processed signal from the Mic/Inst

or Headset input to your audience.

IMPORTANT NOTE: please note that some streaming apps may exhibit some anomalous behavior in the

management of multichannel interfaces. For example, Apps like Facebook for iOS/Android, will only support

channel 1 as input of the audio streaming: this prevents from stereo streaming.

In this case, we suggest to use the iRig Stream Pro as a 2 channel interface. The same if you wish to use the
iRig Recorder App: since this App will only recognise input 1 and 2. For multichannel operation, a different App
is needed, such as: AmpliTube or VocaLive.

How to stream a processed signal

In order to stream a processed signal to your audience (e.g., an effected guitar or voice), follow these steps:

1. Set the iRig Stream Pro to operate in multichannel mode as described above.

2. If you are using an instrument like a guitar or a bass, connect it using a regular 1⁄4” guitar cable to the iRig
Stream Pro’s 1/4” instrument input and adjust the gain level. You can also use a microphone connected to
the XLR input and follow the same following steps.

3. Open a DAW or an App, on the connected host, that supports multitrack recording.

4. Create a mono track assigning Input 3, which corresponds to the Mic/Inst input. This is the track that will be
processed.

5. Insert an effect processor on this track and, if it is not on by default, activate the input monitoring. To activate

the input monitoring option on the track, please refer to the software documentation.

IMPORTANT: make sure that the App you’re using is set to run in Background, this allows you to use it while
you’re using other Apps (such as streaming Apps). To set the App to run in background please refer to the

software documentation.

20

English

6. Turn on the Loopback function on iRig Stream Pro.

ON

LOOPBACK

7. Now the processed signal from input 3 will come back to the inputs 1 and 2: these are the inputs usually
used by your streaming app. You can control the level of the streamed signal by using the “Level”
potentiometer.

8. Open your preferred streaming software and start your stream. Your audience will be able to listen to the
audio that is input to channels 1 and 2.

If you want to use the HEADSET input, you’ll need to create a track and assign input 4 and repeat the above

steps.

Connection examples

Here are some examples of connecting mic or line level signals to iRig Stream Pro.

Connecting headset/phones

1/8"

TRS

It is possible to connect an headset (compatible with CTIA wiring standard) or an iRig analogue microphone to

the “Headset/Phones” port and an headphones to the “Headphones” port. The headset’s microphone gain can

be controlled with the “Headset Mic” thumbwheel. In this case the main Level knob will control the overall signal
level that is streamed to the connected host. If an headphones is connected, its volume can be controlled with

the “Headphones” thumbwheel.

1/8"

TRRS

22

English

Connecting line level signal to the RCA inputs

It is possible to connect any line level source to the RCA inputs. This signal can come from an mp3 player,

a computer or an audio mixer. The main Level knob adjusts the overall volume that is recorded. To adjust

the volume of the device connected to the RCA inputs, use both the volume controls of the device and the

numbered thumbwheel “RCA” on the side of iRig Stream Pro.

IMPORTANT: please note that these are line level inputs and not PHONO inputs so, PHONO signal, needs to be

converted to a LINE LEVEL signal before to be connected.

Connecting microphone

Always connect the microphone to iRig Stream Pro with XLR-to-XLR balanced cable. This will ensure a pristine

and clean performance from your microphone with iRig Stream Pro. Before connecting dynamic microphones
make sure phantom power is turned OFF. Check that the Phantom Power switch is in the OFF position.

23

English

OFF

If you’re using a condenser microphone, it will probably require external phantom power. If phantom power
is ON, switch it OFF, and then connect your microphone. Turn phantom power ON only after the microphone
is connected. If the “Mic/Inst Mute” LED flashes orange, check that working batteries are inserted in the iRig
Stream Pro battery compartment on the bottom side, and that an application that is using iRig Stream Pro is

open.

ON

Before connecting a ribbon microphone, turn OFF phantom power and check the microphone’s operating
instruction manual to see if it requires it. Most ribbon microphones don’t require phantom power, and some can
even be damaged by it. If you’re in doubt just leave it OFF. If the microphone won’t work, check its user manual,

it may need phantom power.

24

English

Connecting instrument

Connect your guitar, bass or any other mono instrument to the instrument input on iRig Stream Pro using an 1⁄4”
plug unbalanced (TS or “mono”) guitar cord.

IMPORTANT: the instrument input on iRig Stream Pro will NOT work if a cable with balanced (TRS or “stereo”)
1⁄4” plug is used.

Connecting RCA, headset and microphone/instrument

It is also possible to connect RCA, headset and a microphone/instrument at the same time. You can adjust the

levels of each inputs with dedicated numbered thumbwheels and the overall level that is recorded is controlled
by the main Level knob.

25

English

Using the loopback function

Direct monitoring

When recording an audio signal into your audio software, there is often a slight delay before it reaches the
outputs of the software and iRig Stream Pro. This delay, called latency, is caused by the computer processing
required to convert and record audio. Since this delay can be distracting, iRig Stream Pro provides a direct
monitoring path from the inputs to the outputs, which is activated by the Direct Monitor switch. When Direct
Monitoring is enabled, the input signal is mixed with the output signal from your audio software and routed
directly to the Headphone outputs. This lets you hear the “live” inputs without latency. The Direct Monitor switch
has no effect on what is being recorded by your software. When using the Direct Monitor feature, make sure any
software monitoring option for direct (or “low latency”) monitoring is disabled. Disabling low latency monitoring
prevents “double-monitoring” of input audio signals when using the Direct Monitoring feature. When “double­monitoring” occurs, there will be an increase in volume and an undesirable “phasing” sound. For more details
about its monitoring function, refer to the documentation for your audio software.

26

English

Troubleshooting

Sound is distorted.

Check that the input level on iRig Stream Pro has been set properly. If the signal LED is red (HIGH) when you
stream your audio, decrease the input level as described in this guide.

I don’t get any sound.

In order for iRig Stream Pro to turn on, a Core Audio-compatible audio app must first be launched on your iOS
device or Mac.

• iOS: be sure you are using an app that works with audio input from the Lightning dock connector.

• Mac: be sure you have set “iRig Stream Pro” as the audio input device on the audio app you are using.

A “phasing” sound is present while monitoring the incoming signal.

If a “phasing” effect is present, you can disable the input monitoring from your recording app or switch off the

direct monitor switch on iRig Stream Pro.

Phantom power doesn’t turn ON.

Check that you have inserted working AA batteries in iRig Stream Pro battery compartment, or that you’ve

connected iRig Stream Pro to an external power supply.

No sound is playback thru the connected headphones.

Use the headphones thumbwheel to set the volume and check the volume of the connected host: you can
control the volume of the host with its volume buttons.
