Thank you for buying this audient product.

As can be found throughout the Audient range, your Sumo has been painstakingly designed
and lovingly nurtured to give you years of productive, reliable, mix fattening performance.
To make the most of this, we suggest that you have a good look through this manual before
you get started.

The safety and installation information will help you to set your Sumo up with the minimum
of danger and hassle, while the operational guide will take you on a whistle stop tour of
Sumo’s knobs, dials and flashy lights – along with some handy hints for their use. Finally, if
you’re experiencing any problems Sumo Surgery will root out most set-up and configuration
issues to get you back on track in no time.

Anywhere you see this symbol, you should make sure to read the
adjacent warning. These will prevent you from killing yourself,
blowing up speakers, and wrecking your mix. All of which are to be
avoided.

Text next to one of these symbols is, wait for it… a handy hint.

These are little operational titbits and guidelines to help you find

your way and get the most out of your Sumo.

Installation

INSTALLATION

Unpacking

Your Sumo has been carefully and
meticulously tested before despatch.

Please check for any signs of transit
damage. If any signs of mishandling are
found please notify the carrier and your
dealer immediately.

Mains Power Supply

Fuses
Sumo can be switched to operate at mains
voltages of either 230V or 115V. With the
switch in the 230V position, the unit will
operate without performance degradation

Mechanical Installation

Care should be taken not to obstruct
the unit’s ventilation holes. Adequate

airflow must be provided within rack
cases above and below the unit to prevent
overheating.

from 210V to 250V. In the 115V setting,
voltages from 105V to 125V will be
accepted. Do not attempt to operate the
unit outside the relevant range defined
above. For 100V operation, please contact
your dealer.

Please note that the fuse ratings are
different for each of the voltage ranges.
20mm T250mA for the 230V setting and
20mm T500mA for 115/100V.

The mains fuse is very unlikely to fail
under normal use and caution should be
exercised if a failure should occur. Check
the mains voltage, the condition of the
mains cord and the integrity of the mains
supply before replacing the fuse.
