Quick Setup for the Sumo
yMake sure all items listed on the front of this guide are in the Sumo's box.
yRead the Important Safety Instructions document included with the Sumo.
yStudy the Hookup Diagram below.
yMake sure all equipment is turned off and all gain knobs are set to zero.
yConnect your keyboard, microphone, or other equipment to the Sumo in the
manner illustrated below.
yPlug in all devices and turn them on. Turn the Sumo on last, after all other
devices.
yExperiment with the Sumo's effect settings.

Front panel operation
1. Channel Volume – Raise or lower the volume for each channel.
2. Effect Mix – Mix in any amount of the master effect.
3. Channel 1 Bass and Treble – Boost or cut the bass and treble for channel 1
by up to +/- 15 dB using these controls.
Note: Channel 1 still runs through the Master EQ section. These controls operate
in addition to the Master EQ for channel 1.
4. Master EQ – Boost or cut the bass, midrange, and treble across all input
channels by up to +/- 15 dB using these controls.
5. Effect – Apply one of fifteen different stereo effects.
6. Master Volume Knob – controls the volume of the signal sent to the speaker,
headphones, STEREO LINK OUTPUT and MAIN OUTPUT.
7. Power switch – Turn the Sumo on and off. When the Sumo is on, the blue
Alesis logo illuminates.

Rear panel operation
8. Power Cord Outlet – Plug a standard IEC cord into this jack and into a
properly grounded AC outlet.
9. Fuse – Replaceable fuse. See the rear panel of the Sumo for details.
10. Fan – An internal fan keeps the Sumo running cool. The fan will remain off until
the unit heats up. Do not obstruct the air flow around this area.
11. Main Output – Plug XLR cables into one or both of these outputs to send a +4
dBu line-level signal to a balanced input on a mixer, recorder, or other audio
device. The Sumo’s effects are included in the Main Output signal.
Note: The internal speaker continues to operate when the Main Output jacks are
used.
12. Headphones – Plug in a set of stereo headphones using a 1/4" stereo plug.
Using the headphone jack disconnects the Sumo’s internal speaker.
13. Stereo Link Output – Use a ¼" tip-sleeve (TS) cable to connect this jack to
the input of another amplifier for true stereo. The Sumo provides true stereo
output instead of the standard mono; many of the Sumo’s excellent effects will
sound even better when you listen to them in stereo. If you don’t have a second
amplifier, you can enjoy the stereo effects by listening with headphones.
14. ¼"Instrument Inputs – Use ¼" cables to connect synthesizers, drum
machines, and other devices. Use two cables for stereo. For mono sources, use
either one of the the left and right inputs.
Note: For the cleanest signal, use "balanced" tip-ring-sleeve (TRS) cables.
"Unbalanced" tip-sleeve (TS) cables may also be used, but they are more likely to
conduct hum and other electromagnetic noise.
15. Microphone Input – Plug a microphone into this input using an XLR cable.
You can use both the microphone input and the ¼" inputs on channel 1 at the
same time.
Note: The microphone input does not provide phantom power.

Effects
The Sumo contains an advanced, stereo effects processor with fifteen different programs.
Here are those programs as you rotate the Master section’s Effect knob clockwise,
beginning at the "off" position (with the knob pointing straight down).
Effect name Description
Rotary Rotary speaker emulation. This effect is
especially popular with organ sounds.
Hall 1 The reverberation of a bright concert hall.
Hall 2 The reverberation of a warm concert hall.
Delay 1 A short (125 millisecond) slapback delay.
Delay 2 A longer (190 millisecond) and longer-lasting
(more regenerative) delay.
Chorus Stereo chorusing, which adds a thickness to the
sound.
Flange Stereo flanging, which alters the phase of
incoming audio signals to produce jet-airplane-
like whooshing sounds.
Room 1 The ambience of a studio constructed with hard
wood walls.
Room 2 A room sound optimized to acoustic instruments
and synthesizers. Reverberation time is shorter
than that for the other rooms.
Room 3 A room sound optimized for guitars and other
rhythm instruments.
Plate 1 The classic plate reverb sound for vocals and
lead instruments.
Plate 2 A brighter, more sizzling plate reverb sound that
works well on vocals and drums.
Plate 3 A warmer, more vintage sounding plate reverb
sound.
Chorus/Room 1 A combination of chorus and reverb.
Chorus/Room 2 A darker-sounding combination of chorus and
reverb, with a touch of wah-wah.
Choose an effect by using the Master section’s Effect knob. Then, within each individual
channel, rotate the channel’s Effect knob to increase or decrease the amount of the effect to
be applied to that channel.
Turn the Effect knob to "off" to disable the onboard effects.
