iRig Acoustic Stage
Thank you for purchasing iRig Acoustic Stage.
Your package contains:
• iRig Acoustic Stage
• 2xAA batteries
• iRig Acoustic microphone
• Belt clip
• Pouch
• Quick Start Guide
• Registration Card
iRig Acoustic Stage is a revolutionary digital microphone system for Acoustic Guitar, both with steel and nylon
strings.
We all know that the best possible sound when recording an acoustic guitar is the one you get with a classic
studio microphone in a well sounding studio, with a great preamp and proper positioning, and we all know how
compromised the sound of a typical stock or after-market piezo pickup system is.
The typical under-saddle piezo pickup system takes all the air and acoustic qualities from the instrument out of
the picture. All the subtle nuances and harmonics of a great acoustic instrument are normally lost with bridge-
mounted pickup systems.
The main functionality of iRig Acoustic Stage is to make your guitar sound exactly as if it was captured with
a classic recording studio setup with a very simple clip-on microphone that can be applied in seconds to any
instrument.
The synergy between the microphone, the preamp and DSP unit creates an incredible natural-sounding tone
for any acoustic instrument. It features 3 tone presets — natural, warm and bright — for both steel string
and nylon string instruments. And while, when compared to piezo pickups, iRig Acoustic Stage makes any
instrument sound dramatically better right out of the box, you can also calibrate the system to precisely fit the
sonic signature of your instrument and playing style allowing it to draw out the full acoustic potential of your
instrument.

Installation and setup
1. Insert the provided batteries in the battery compartment. You can use both Alkaline or Ni-MH rechargeable
batteries. High energy Ni-MH will last at least 18 hours. Tip: If you play frequently, a good suggestion is to
have 2 sets of rechargeable AAs, one in use and the other on charge and swap them every 2-3 gigs.
2. Connect the iRig Acoustic microphone.
3. Fix the microphone to your instrument. If the soundboard of your instrument is very thin the iRig Acoustic
microphone may not stay perfectly steady during use. To solve this you can add one or more layers of
adhesive tape inside the iRig Acoustic microphone slot to make it a perfect fit for your instrument.

4. Connect the iRig Acoustic Stage output to the PA mixer or to an acoustic guitar amplifier, as you would do
with a normal acoustic-electric guitar.
5. Turn ON the unit. Tip: Always turn down the channel volume on the mixer or the volume of the amp before
turning ON or OFF iRig Acoustic Stage!

6. While you can immediately start using your iRig Acoustic Stage with great results, if your instrument already
features an onboard undersaddle piezo pickup system you can also connect its output to iRig Acoustic
Stage. This will give more flexibility to your tone, allowing you to mix the iRig Acoustic microphone and the
guitar built-in pickup system.
English

7. When recording the guitar in the studio or performing live on acoustic sets, best results will be obtained by
using the iRig Acoustic Stage microphone only. This is obtained by just leaving the AUX input disconnected,
or by rotating the MIX control completely clockwise. When performing live with loud sets and, depending on
the type of sound you’re after, it might be useful mixing-in a portion of the guitar’s built-in piezo pickup. This
will make the system less feedback sensitive and will add some definition and punch from the piezo pickup
that can be desirable in certain cases. This is obtained by setting the MIX control to 50% as a starting point
and experimenting with other mix levels to find the best spot.
English

8. When mixing the guitar’s on-board pickup system with iRig Acoustic using the MIX control, always start
by setting this switch to the 0° position. On certain guitars you might get a fuller and more natural sound
by flipping the phase of the AUX input by setting this switch to the 180° position. When no AUX input is
connected this switch reverses the phase of the iRig Acoustic Stage output, and it can be useful when
playing in front of loud stage monitors to experiment with both positions to find the one that gives less
feedback and a more solid tone.
9. Use the volume knob to adjust the overall output signal. This control can also be used to turn the guitar
down between songs as it is easy to operate even if you can’t see the unit. Tip: Always keep a bit of margin
when playing so that you can always quickly turn it up if you would need to. Also remember to push the
control in, once you set the volume as preferred, to avoid accidental movements of the volume control.
English

10. Use the belt clip to attach the iRig Acoustic Stage to your belt or your instrument’s shoulder strap.
11. iRig Acoustic Stage can also be used as a digital recording interface for computers. Just plug the USB
Digital Audio Output to any computer equipped with recording software (for example Apple’s Garage
Band) and you’ll be ready to record the guitar with a pristine full digital path. This will ensure professional
quality recording results with a minimal effort and ultra quick setup. You can connect iRig Acoustic Stage
to: Mac computers, Windows based computers, iOS devices (using a Camera Connection Kit accessory)
and Android devices (using an OTG cable, not included). To connect iRig Acoustic Stage to a computer for
recording you need a Micro USB to USB type A cable (not included). When connecting iRig Acoustic Stage
to a computer using the USB port, iRig Acoustic Stage will be powered by the USB port. For this reason you
don’t need batteries installed when using iRig Acoustic Stage this way.

Cancel feedback button
In case of a feedback tap the “CANCEL FEEDBACK” button and the troublesome frequency is instantly notched
out of the mix, thus eliminating feedback without sacrificing tone quality. This feature set individuals notch filters
(up to 10) for multiple feedback frequencies.
1. Press this button while a feedback occurs. Available filter storage locations are: “10”. When a filter is stored
the button will flash one time red. If no filter is stored no flash will occur.
2. Reached the maximum filters storage available, the next press of the button will cause the button to blink
four times.
3. To reset all the filters stored, keep the cancel feedback button pressed for at least 2 sec. The button will turn
off.
Tip 1:
A good practice to be “feedback safe” while performing is to follow these steps:
- while setting the sound for the gig just raise the iRig Acoustic Stage channel volume (slowly) up to when the
system starts to feedback. Then, while the feedback is starting to sound as a steady note, press the CANCEL
FEEDBACK button. The feedback will disappear.
- you can then increase the volume even further and “cancel” another feedback frequency that may appear.
- put the volume level down back to the normal level you will use for the gig.
Tip 2:
When playing onstage acoustic instruments it may happen that some low notes start resonating too much with
the monitor speakers or with the PA system when played.
This is particularly annoying while playing.
iRig Acoustic Stage allows you to solve this problem this way:
- play the “critical” note and while the note is resonating press the CANCEL FEEDBACK button.
This will attenuate the note to make it level with the others and no longer a critical spot.
English

Tone button
Press TONE multiple times to select the tone you prefer.
• “NATURAL” provides a balanced tone typical of a large diaphragm microphone placed at the golden spot
when making studio recordings.
• “WARM” provides a smoother tone, useful when NATURAL tends to sound a bit too harsh or edgy
• “BRIGHT” gives a brighter tone, useful to have it cutting thought the mix in complex live setups
All the three settings apply to both steel and nylon strung instruments. Nylon will toggle ON or OFF every time
the presets are cycled.
Make sure NYLON is ON on nylon strung instruments (yes, including Ukuleles!).
Each press of the TONE button will select different preset, cycling this way: NATURAL -> WARM -> BRIGHT ->
NYLON (on) - > NATURAL -> WARM -> BRIGHT -> NYLON (off) - > NATURAL......
English

Instrument calibration
The calibration process improves the overall response of the presets by tailoring them to the specific response
of your instrument. By default this button’s LED is red to indicate no user calibration has been performed yet,
and the factory calibration is loaded. This factory calibration has been created to make virtually every instrument
sound natural and balanced. You can use the factory calibration (TONE button RED) on steel strings guitars
of any kind, nylon strings guitars of any kind, acoustic basses, ukuleles and so on. The sound will always be
balanced and natural thanks to the proprietary digital processing system iRig Acoustic Stage performs. If you
are playing Steel stringed guitars and would like to make the iRig Acoustic Stage processing specifically tailored
for your instrument, you should perform the Instrument Calibration process.
(see notes below).
In the table below are listed the typical situations when it is useful to perform the instrument calibration:
Instrument TYPE CALIBRATION
Steel strings - Dreadnought Optional, will improve every instrument even if Factory
Calibration already sounds great.
Steel strings - Jumbo, Parlor, “001”, and other styles
different from Dreadnought
Optional, can be effective, but, depending on the
instrument, can also “flatten out” some peculiar
aspect of the guitar tone. Since results depends on
the instrument, it should be experimented with.
Nylon strings - any type Normally not useful. Factory Calibration sounds great
on Nylon instruments, can anyway be experimented.
Non-guitar instruments like: Ukuleles, Acoustic
Basses, Mandolins, etc..
Not advisable. Will make the instrument sound
unnatural. Factory calibration sounds great on these
instruments.
Calibration process
As soon as a calibration has been successfully completed the button will turn green.
To start the calibration the iRig Acoustic microphone must be connected:
1. Keep pressed the Tone button for at least 2sec (after 2 sec begins the calibration process).
2. The four presets LEDs will start to blink along with the TONE LED
English
13
3. Proceed playing 6 strings clusters in semitones steps on your guitar. Try playing these clusters using the
same dynamics you will be averagely using when playing. If you play too soft during calibration, the system
will probably deliver a too bright response. If you play very hard the system will produce a too soft response.
We suggest checking the online tutorial videos to see how calibration clusters should be played. Tip: The
fact that the calibration end results depends on how you play the calibration clusters is actually something
very useful once you get used to it because it allows to have specific calibration for your instrument just
changing the way you play during calibration. This is going to be fun once it will be familiar because it will
open up the possibility to create very specific and personal tones with your instrument!
4. To confirm the calibration press the TONE button. The TONE button LED turn GREEN to indicate the
calibration has been saved.
English
14
5. To abort the calibration press the FEEDBACK CANCEL button. iRig Acoustic Stage will return to the
previous state.
6. To return to the factory default calibration: start the calibration as per point (1) above then, while the
calibration process is going on, press the Tone button for at least 2 sec.
NOTE 1: the calibration process has a time out of “60” seconds. After this time the process automatically ends.
NOTE 2: the calibration can start only if the microphone is connected.
Phase switch
The phase flip switch (0°-180°) works pre-mix. When both the MEMS and the Piezo are connected the phase
switch acts on the MEMS signal. When only the MEMS is connected it act on the MEMS signal. When only the
Piezo is connected it act on the Piezo signal.
English
15
AUX IN
Most acoustic guitars used for live performance includes a piezo pickup in the bridge.
This is of course very useful to amplify the instrument but we all know the sound of the piezo pickup does not
actually represent the true tone of the guitar when played acoustically.
With iRig Acoustic Stage AUX IN you can connect the output of your guitar to this input and mix the stock guitar
pickup output with the iRig Acoustic microphone tone.
This will allow to keep using the powerful and reliable output of the piezo pickup onstage in feedback-critical
situations, with just a touch of the iRig Acoustic microphone mixed in to make it sounding way more acoustic
and rich.
Use the MIX control to balance the tone between the Piezo pickup (fully CCW) and the iRig Acoustic
microphone (fully CW).
When using both the AUX and iRig Acoustic sources make sure to experiment with the PHASE switch on the
left side of the iRig Acoustic Stage to make sure you set it on the position where the two sound sources mixes
together the way you prefer.
Low battery indications
When the battery level approach to be low, all the (turned ON) LEDs will fast blink every “2” sec. When the
battery is at a very low level the audio out is muted and the LED continuously blinks.

安装和设置
1. 在电池盒中装入提供的电池。还可以使用碱性或镍氢可充电电池。高能量镍氢电池可续航至少18个小
时。Tip：如果您常常弹奏，最好有2套可充电AA电池，使用其中一套的同时可以给另外一套充电，方便随时更
换。
2. 连接iRig Acoustic麦克风。
3. 调整麦克风适应您的乐器。如果乐器的音板很薄，那么使用过程中iRig Acoustic麦克风就无法保持稳定不晃
动。要解决这个问题，您可以在iRig Acoustic麦克风的内部插槽中贴上一层或多层胶带，使其完美适合您的乐
器。

6. 您可以立即开始使用iRig Acoustic Stage，并会获得很好的结果，如果您的乐器上已经有板载下弦枕下压电
拾音器系统，也可以连接它的输出到iRig Acoustic Stage。这可在音色上带来更多的灵活性，允许您混合使用
iRig Acoustic麦克风和吉他内置拾音器系统。
7. 在录音棚录制吉他或在原声设置上现场演出时，只有使用iRig Acoustic Stage麦克风才能获得最佳结果。这
在AUX输入断开连接或完全顺时针旋转MIX控制时可获得。当用响亮的设置现场表演，依据声音类型，它可能
在混合吉他内置压电拾音器的一部分有用。这可以使得系统减少反馈敏感度，并添加一些压电拾音器的定义和冲
头，在某些情况下可取。这通过设置MIX控制以50%作为一个起始点并尝试其他混音水平找到最佳点。
