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 bridgemounted 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.

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.

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.

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.
