Welcome

Thank you for making Fishman a part of your acoustic experience. We are 

proud to offer you the finest acoustic amplification products available

high-quality professional-grade tools to empower you to sound your very 

best. We are confident Aura Spectrum DI will both enhance and inspire 

your music making.



3

Quick Start

Power – Install a fresh 9V battery (not included) or connect a Fishman 

power adaptor.



Set the controls – Volume at minimum and all other controls as 

shown below.



Plug in – Use standard ¼-inch and XLR shielded instrument cables.

Tune up – Step on the tuner footswitch to tune with the output muted.

Set trim – Play hard and adjust the input trim (on the right side) so the 

clip/batt LED flashes only occasionally.

Select an Image – Raise the volume and audition Images with the 

select knob. Move the Image Bank slider to choose the set of Images 

that best match the instrument you’re playing. (see pages 6 thru 13)



Blend to taste – Turn left for more pickup and right for more Image.

Kill feedback – If feedback starts, change the position of the phase 

switch. For advanced feedback handling, check out the section detailing 

the automatic feedback filters on page 24.

What is Aura?

Aura Acoustic Imaging Technology uses digital algorithms developed in 

Fishman’s audio laboratories to restore a studio-miked sound to an  

acoustic instrument. To achieve this, we record instruments using world-

class microphones and techniques to capture an “Image” of the natural 

sound that your acoustic instrument emits when miked in a professional 

studio. This Image, when recorded direct or played through an amp, 

mixer or PA, blends with your instrument’s pickup to produce an incred-

ibly accurate recreation of the original recording.

Aura Acoustic Imaging processors sound best when used with Fishman 

undersaddle pickups and magnetic soundhole pickups. When we record 

each instrument, we use our Acoustic Matrix undersaddle pickup. So, 

when you play through an Aura processor, you’ll get the best results using 

our Acoustic Matrix pickup. We do not recommend soundboard-mounted 

pickups, bridge-plate pickups, multi-sensor pickups or microphones for 

Aura products since they include unnecessary resonances that can inter-

fere with the Aura processing.

Choosing an Image

To get the most realistic tone from Aura Acoustic Imaging, you should 

always match your Images with the instrument type you’re playing. For 

example, choose dreadnought Images when plugging in a dreadnought 

body style guitar; choose mandolin Images if you’re playing a mandolin. 

Don’t hope to derive a mandolin sound from a dreadnought or try to turn 

your orchestra body style guitar into a 12-string. If you are not sure which 

body type your guitar falls into, we suggest you audition several Images 

from each bank and let your ears decide. See the following pages to help 

match your instrument with the best Aura Image.

Aura Custom Shop

For the ultimate in Aura Imaging, be sure to check out the Aura Custom 

Shop at fishman.com. For a modest fee, you send us your instrument and 

we’ll create a set of Images using our best microphones, custom  

recorded for you.

Aura Image Gallery

The Aura Image Gallery software manages a vast library of Images  

created from an ever-expanding list of instruments, and provides tools to 

search and store sets of Images. Browse the Image Library to find your 

instrument, then drag and drop an Image into an Image Set for download 

into Aura Spectrum.



Making Connections

Playing live

For the best sound reproduction when performing live, connect your Aura  

Spectrum to an acoustic instrument amp, a PA system, a powered moni-

tor or other full-range system. The balanced XLR D.I. output eliminates 

an outboard D.I. and features an automatic ground lift when you use the 

1/4” output, providing a high quality, noise free signal.



Going direct

For direct recording, there is no better solution than using Aura  

Spectrum’s balanced XLR D.I. or 1/4” output. In fact, an acoustic track 

recorded with just a pickup can be re-recorded using Aura to restore the 

miked sound.

14

Left Side Panel

Output

Use a standard ¼-inch instrument cable to connect the output to your 

amplifier, mixer or effects devices. You can also connect this output to 

an unbalanced input on a recording system.

Connecting a guitar cable here will also lift the ground on the XLR D.I. 

output, preventing unwanted ground loops.



FX Loop

This tip/ring/sleeve connection allows you to insert external devices, such 

as the Fishman AFX Acoustic Effects, between Aura Spectrum’s blended 

signal and the main outputs. Any pedals you connect here will appear at 

the 1/4” and XLR D.I. outputs. The overall output level will still be affected 

by Aura Spectrum’s volume control.



9VDC

Power may be supplied by either a 9V battery (battery compartment 

underneath the pedal) or the Fishman 910-R (for 110V).


15

Right Side Panel

Trim

Raise or lower the trim to optimize the input level for your pickup. Play 

hard and adjust trim so clip/batt flashes occasionally. Some pickup 

systems may not cause the light to flash at all and other onboard preamps 

may require you to turn their output down to achieve an optimum level.

Phase

Use the phase switch to improve bass response at low volume and sup-

press feedback at high volume. Move the phase switch and leave it in 

the position most pleasing to your ear.



USB

After installing Aura Image Gallery software, connect your computer here.



Input

Plug in your guitar here with a standard ¼-inch instrument cable. If you 

have a passive undersaddle pickup (no battery onboard), always plug into 

the Aura Imaging Pedal first, even if you use a pedal tuner.

Insert a plug into the input jack, and the Aura Imaging Pedal powers up. 

To conserve the battery, remove the plug from the input when not in use.



16

Top Side Panel

XLR D.I. Output

Connect a standard microphone cable here to feed recording equipment 

or a sound reinforcement mixing console. When the 1/4” output is also 

connected, this D.I. output’s ground is automatically lifted to prevent any 

unwanted ground loops.


17

18

Front Panel Controls

Volume

The volume control affects the overall output level coming from both 

the 1/4” and the XLR D.I outputs. For the cleanest signal, set the volume 

as high as possible without clipping the next device in the signal chain. 

If you hear distortion and the clip/batt light is not flashing, reduce the 

volume.


19

Select

The select knob allows you to choose among 

the 16 Images available for each of the eight 

different Image Banks. Move the select slider 

to choose a bank of Images that best match 

the style of instrument you’re playing, then 

select through the 16 Images to find the ones 

that sound best. Try all 16 within each bank 

and adjust the blend knob to obtain more or 

less character.



Blend

Position the blend knob straight-up at 12 

o’clock and you’ll hear a 50/50 mix of Image 

and pickup. Turn the blend all the way right 

for just Image; all the way left for just pickup. 

Most performers blend in some pickup with 

the Image for clarity and definition.

Suggestions

• For live performance try backing off the Image by setting blend 

to about 10 or 11 o’clock or about 65% pickup. You won’t need 

too much Image blended in to achieve a great live sound. If 

feedback occurs, flip the phase switch.

• For recording, try blending in more Image for a realistic  

acoustic sound. Set the blend to taste. Again, you’ll often get 

good results with a little bit of pickup blended in with the Image 

for clarity and definition.

Front Panel Controls (cont’d)

Pickup EQ:  Low, Mid, High

As a default, the lowmid, and high tone controls affect the sound of 

the pickup signal only, allowing you to further refine the sound of your 

instrument without excessive alterations to the chosen Image.

A Global EQ mode may also be selected, applying the same EQ settings 

to both the pickup and Image path simultaneously.



Compressor

The compressor control adjusts several 

settings within a sophisticated automatic 

leveling circuit. 

As you turn this knob clockwise, your overall 

playing dynamics become increasingly lim-

ited, making softer notes louder and con-

trolling loud spikes in your playing. This can be helpful in performances 

where you desire a more even level to your playing. At its maximum  

setting, there may be some overall increase in the output level.

21

Global vs. Pickup EQ

When shipped from our factory, the lowmid, and high tone controls  

are set to affect the sound of the pickup signal only. This is referred to 

as Pickup EQ mode. However, a Global EQ mode may also be selected 

which applies the same EQ settings to both the pickup and Image signals  

simultaneously (or “globally”).

When you power on Aura Spectrum, watch the tuner display for a “P” or 

a “G” indicating the currently selected mode.



To select Global EQ mode:

1. Hold the tuner button while Powering on.

2. The display flashes a “P” indicating that the unit is currently in 

Pickup EQ mode.

3. Press the anti-feedback button once and the display now 

flashes a “G” indicating Global EQ mode is now selected.

4. Press the tuner button to select Global EQ and resume  

powering on to normal playing mode.



To return to Pickup EQ mode:

1. Hold the tuner button while Powering on.

2. The display flashes a “G” indicating that the unit is currently in 

Global EQ mode.

3. Press the anti-feedback button once and the display now 

flashes a “P” indicating Pickup EQ mode is now selected.

4. Press tuner button to select Pickup EQ and resume powering 

on to normal playing mode.



22

Front Panel Controls (cont’d)

Tuner Footswitch

Step on the tuner footswitch to enable the digital chromatic tuner. You’ll 

know it’s active when the white Aura LED goes dark and the tuning fork in 

the center display is lit red. As a default, Aura Spectrum’s output is muted 

allowing you to tune silently.

To tune, play a note lightly and watch the display. The note name will be 

indicated as a single letter and a small # sign will be lit whenever the dis-

played note is raised one half step. The note being sharp, flat, or in-tune 

will be displayed using the five multi-colored LEDs in the tuner window 

and below the tuning note. When there is no audio input, or you’re not 

playing, a “–” will appear in the display.

This digital chromatic tuner accommodates all standard and alternate 

tunings and is calibrated to A = 440.


23

Tuner Option

When shipped from the factory, the audio output is muted when the tuner 

is engaged.

Alternately, you have the option to use the tuner without muting your out-

put. To choose this option, hold the footswitch down until the Aura LED 

flashes. Repeat to return to the factory state.



Bypass mode

Aura Spectrum allows you completely bypass the Image, EQ, and Com-

pressor processing. To enter bypass mode, press both the anti-feed-

back and tuner switches together. The white Aura LED will alternate 

slowly with the tuner LED to indicate bypass mode is active. To exit 

bypass mode, press both foot switches again.

With bypass active, all controls including the tuner are functional,  

however you will not hear any of the changes until you exit bypass.

Front Panel Controls (cont’d)

Anti-Feedback Footswitch

Use this search-and-destroy anti-feedback filter in addition to the phase 

switch to control feedback during a performance. Aura Spectrum’s  

automatic anti-feedback filter can apply up to three separate notch 

filters, which are essentially very precise tone controls that reduce only 

a small piece of the audio band. When activated, the filter determines 

where the offending resonances are and only reduces the frequencies on 

which they are centered.

While the 

anti-feedback

 control is very effective, it’s best if you spend 

some time while setting up before a performance and catch any issues 

before you begin to play. With some practice, you’ll find you can also use 

it to “fix” any resonant notes that may stand out in a particular venue.

Using the automatic 



anti-feedback

 control:

1. Press and hold 

anti-feedback

 footswitch for 2 seconds. The tuner 

display will flash a “

1

” to indicate it is searching for the first feedback.

2. Turn up your 

volume

, then either dampen the strings while tapping 

the body or play the troublesome note until the feedback begins. The 

filter will automatically identify and eliminate the feedback. The “



1

” in 


the display will light solid as will the “

A-F

” indicator.

3. At this point, you may continue to turn up your 

volume

 as in step 2 

to catch up to two more problematic resonances. Each is indicated via a 

flashing “



2

” or “


3

” during the search, turning to solid lit numerals when 

the resonance has been identified.

4. You may tap the 



anti-feedback

 footswitch at any time to cancel the 

search. The circuit will hold the offending frequenc(ies) in memory until 

you repeat the process again.

You may also turn the filter on or off at any time by tapping the foot-

switch. When enabled, the “



A-F

” lights to indicate the filters are active 

and the number of filters being applied will be briefly displayed.


25

About Phase and Anti-Feedback

There are two features provided to help control acoustic feedback, the 



phase switch and the 

anti-feedback

 control.

Feedback usually occurs in the lowest octaves of your instrument. The 

natural resonances which produce an instrument’s tone also react with 

amplified sound. The louder an instrument is amplified, the more it will 

interact. Feedback occurs when a note on the instrument resonates in 

sync with the amplified sound, reinforcing and building to a sustained 

howl.


The phase switch flips the polarity of your instrument signal from  

positive to negative, changing its relationship to the sound coming from 

the amplifier. One phase setting usually provides better resistance to  

feedback than the other and will vary depending on the instrument and 

playing environment. Another approach to determining optimal phase is 

the selection which sounds or feels most natural when playing.

The phase switch also affects the signal polarity to the balanced XLR 

D.I. and 1/4 inch outputs, synchronizing the amplifier with other sound 

systems in use.

In certain playing environments the phase switch may not have an  

audible impact.

The 


anti-feedback

 control is an automatic variable frequency notch fil-

ter designed to subdue a resonant peak on the instrument which is prone 

to feedback. Check out page 24 for more exact details of its operation.



26

Downloading Images

The Aura Image Gallery software manages a vast library of Images cre-

ated from an ever-expanding list of instruments, and provides tools to 

search and store sets of Images.

If you can’t find your exact instrument in the list, use the built-in Image 

Wizard to find the closest match. For example, if one of our hundreds of 

Images doesn’t match your instrument exactly, you can still find a great 

sounding Image by matching similar tone woods and body styles. Experi-

ment with these tools, and use your ears to determine what sounds best 

for your playing or musical style.

To access this library of additional instrument Images, install the Aura  

Image Gallery on your computer. Then, gently remove the USB cover 

from the right side of the unit and connect the included USB cable to the
