CURRENT DRAW
The next step is to verify the current draw. You
would only be able to know this by reading the
manufacturer’s instructions for the effects pedal
you are using. If the requirement is over 100mA and
under 300mA, you will need to use outputs 7 and 8
on the Aetos. For anything less than 100mA, you
can use channels 1-6 (Note: using the high current
output channels 7 and 8 for a low current draw
pedal will work fine and will not hurt the pedal. The
high output only refers to the capacity of the
current that can be drawn). Most analog pedals (not
all analog pedals), require under 25mA, for
example, most overdrives, fuzz pedals, boost
pedals, distortion and compression pedals are
transistor based and do not have the large number
of components that digital pedals do. Digital pedals
have DSP chips (digital signal processors) which
are micro controllers that contain thousands of little
transistors on the single chip along with Analog to
Digital Converters (ADACs), Memory chips and
other components that draw far greater current
than analog pedals.
BACK PANEL A
WARNING:
If product is defective, do not attempt to fix it
yourself. Please contact Walrus Audio to for help.
If
the backplate has been opened on the Aetos,
the warranty for your product will be voided.
WHAT TO DO IF REPAIR IS NEEDED:
If the product has become defective during the
duration of the 5 year warranty, please contact
Walrus Audio and setup an RMA (Return Merchan-
dise Authorization). Once determined by Walrus
Audio that the product needs repair, Walrus Audio
will send you an RMA reference number. Then ship
the Aetos back to Walrus Audio, including your
warranty card and purchase receipt. You will also
need to include a pre-paid return shipping label in
the package. You must write the provided RMA
reference number on the box or it will not be
received. (We only accept FEDEX or UPS shipping
methods).
We are not responsible for the returned
product until it is received on our dock and
scanned as ‘delivered’ by the shipping company.
Do not attempt to return a product without first
receiving an RMA reference number.
INTRODUCTION TO CLEAN (ISOLATED) POWER
The Aetos is designed around a custom-wound
toroidal transformer, providing isolation to each of
the 8 regulated outputs channels. The alternatives
to multi-output isolated power supplies are
individual wall-warts and daisy chains. Wall-warts,
which do offer isolation, often lack the filtering that
is necessary for audio applications and they take
up an enormous amount of space. The daisy
chain power supplies, while being cheap in price,
often have grounding issues as a result of having
multiple pedals pulling different currents from the
power source creating ground loops and magnetic
field issues. The noise is increasingly evident if
you are powering higher current modulation
effects or more than a few pedals. The advantages
of isolated power supplies are well documented,
but in summary, having each pedal in your chain
have its own isolated power channel prevents
‘leakage’ of ground loops or the magnetic field of
one pedal onto the power channel of another.
These ground loops are often what introduce the
hum and buzz into the signal chain. Isolated or
“Clean Power” is the best choice for serious
players and highly recommended for all Walrus
Audio products.
POLARITY
The next step is to check the polarity of the device
you are using. The vast majority of DC powered
effects pedals are negative ground, much to the
result of most early pedals being powered off of
9VDC batteries with the negative terminal of the
battery connected to ground. Carrying on with the
trend, most pedal manufacturers design ‘negative
to ground’. The majority of DC jacks are center
negative and have a 2.1mm center barrel. Most of
the market has followed the lead of boss and
Ibanez and has standardized this jack for their
pedals. For all standard effects pedals with center
negative 2.1mm barrels, you can use the
Black-to-Black barrel connectors. Specifically, for
line 6 pedals, you will have to use the Black-to-Red
connectors. If you have a question about the
voltage requirement of your pedal or which of the
Aetos outputs to use, contact us at

WARNING:
1) Input Voltage Requirements – 230V (60Hz).
This product will be destroyed if any other input
voltage is used voiding the warranty.
2) If backplate is opened, the warranty is
immediately voided. For repairs or questions,
contact Walrus Audio directly at sales@wal-
rusaudio.com
3) Always check the power requirement of the
pedal you are plugging in to,
