Quick Start
�
Your Hot Hand comes with the following components.
Carrying Case
Hot Hand Extension
Hot Hand Arm Band
4 AA Batteries
01 : Power
The first thing you will need is power. Your Hot Hand
™
unit comes with 4 AA
batteries to get you started. The batteries will typically last about 15 to 20
hours. To avoid concerns about battery life, we recommend you buy a Source
Audio 9V DC power supply (A) (see power supply note on page 14 for exact
requirements).
02 : SENSOR IN connection
Next, connect the supplied EXTENSION CABLE to the SENSOR IN jack (B). Later,
you’ll plug the other end into the wire that trails from the Hot Hand, but hold
off on that for now.
B A
Hot Hand Control Box
03 : Guitar/Audio Connections
Now, you’ll need to make the audio connections. Plug a regular ¼-inch
guitar cable from your guitar into the GUITAR IN jack (C). Connect your amp
(or other audio device) to the GUITAR OUT jack, again with a regular ¼-inch
cable (D).
Note: Plugging a cable into the input will turn the unit on, causing the LEDs
Hot Hand Rings (5 sizes)
Hot Hand Motion Sensor
to light up briefly. Don’t forget to turn off the unit by unplugging this cord—
otherwise the battery will continue to drain.

04 : Attaching the Hot Hand Motion Sensor
Choose the ring size which fits most comfortably. This is ideally placed on the
middle or ring finger of your strumming hand (A). Put your guitar on and take
out the Hot Hand sensor. Insert the Hot Hand into the ring as shown. To prevent the sensor cord from interfering with your playing, use the provided arm
band (B) to hold it up near your elbow as shown. Once everything is comfortable, attach the wire that comes from the Hot Hand into the EXTENSION CABLE.
Note: the extension cable is not required for operation, but it is almost certainly required for using the product in the standing position. When the Hot
Hand is connected, and the control box is powered-on, a blue LED will glow in
the sensor to indicate is it ready to be used (C).
A
05 : Calibration (optional)
Calibration is recommended, but not required. See page 11 for additional
information.
Calibration is easy. Just turn the Effect Selector knob to the Calibrate (A)
position and hold your strumming hand in its normal playing position over
the strings. Your hand should be held relatively still. Then, tap the On/Off
pedal once (B). The On/Off LED will blink for a few seconds. When the LEDs
are off, you are calibrated and ready to go. Turn the Effect Selector knob away
from the Calibrate position to select an effect.
06 : Brief Knob, Pedal, and Button Descriptions
(see pages 11-15 for more detail.)
• EFFECT Knob: Selects the desired effect.
• FREQUENCY Knob: Adjusts the filter characteristics of the effect.
• MOTION Knob: Adjusts the sensitivity of the motion sensor.

The Hot Hand Concept
The concept of Hot Hand is to provide a new way to control effects. Our first
product, the Hot Hand Motion Controlled Wah Filters, is focused on controlling the response of one of more filter types. Until now, the only way to do
it was with your feet on an expression pedal or with an auto-wah effect.
The downside of the expression pedals in that you’re rooted to one spot on
the stage and there are limits on how fast the pedal can move up and down.
The shortcoming of auto-wah effects is they can only follow the amplitude
envelope of the sound.
With Hot Hand, you’re not glued to your pedals and you have more control
over the wah sound than with previous solutions. Plus, it adds the potential
for additional showmanship in live performances. The movement of your
hand up and down as you play the guitar becomes the expression pedal.
It is worth noting that the Hot Hand sensor can be mounted on any part of the
body that moves. We have experimented with both mounting to shoes as well
as to head bands. The latter is very fun to watch!
The Controls
The Hot Hand Control Box is where all of the effects are created and controlled. The product contains 11 different wah/filter effects. Some sounds are
classics, others are new, and all have been carefully modeled and created by
real musicians. And by using the PRESETS, you can switch between FOUR of
those sounds without ever bending down to tweak a knob on stage.
Note that the Hot Hand control box uses rotary encoder knobs and LED
rings. This allows you not only see the knob locations in low light situations,
but you can also jump from one preset to the next and see the setting of each
knob quickly.
The product also gives you control over the FREQUENCY of the wah and the
sensitivity of the Hot Hand. These features allow you to make adjustments to
how the Hot Hand interacts with the effect that you have selected.
There are three other features related to external “expression” control. First,
the EXPRESSION IN allows you to control the effects in the Control Box with
an external expression pedal. The EXPRESSION OUT allows you to take the Hot
Hand signal and use it to control other effects boxes that have an Expression
Input feature. Finally, the SENSOR OUT jack allows you to send the Hot Hand
signal to other Source Audio Hot Hand products and control them with a
single motion sensor.
EFFECT Knob
The EFFECT knob switches between different types of wah sounds. Note that
AUTO WAH is not impacted by the Hot Hand signal. The VOLUME SWELL setting
allows you to use the Hot Hand for volume swell or tremolo effects. For a
description of each effect, please see page 18.
Calibration (optional)
Your use of Hot Hand will benefit from the unit being calibrated to your playing position and style. In effect, you are telling the control box where your
hand is when it is centered over the strings. Calibration is recommended
when using for the first time or when your playing position changes due to
guitar strap changes or when moving from standing to sitting. If you do not
calibrate, the “zero” or center point of the Hot Hand signal may not match the
natural resting position of your hand.
To calibrate, turn the EFFECT knob to the CALIBRATE position and hold your
strumming hand in its normal playing position over the strings. Then, tap
the ON/OFF pedal once. The LEDs will blink for a few seconds. When the LEDs
are off, you are calibrated and ready to go. Please note that the effect will be
muted when the selector is in the calibrate position.
ADVANCED USER NOTES
1) The calibration “zero” point does not necessarily need to be in the middle of your arm stroke.
By setting the zero point higher or lower it is possible to span a different range of the effect.
Also, calibration may be required if the Hot Hand sensor is mounted to some other part of your
body (head, foot, etc.)
2) One calibration setting is typically used across all presets. However, it may desirable to create
a different calibration setting for each preset. When the function selector is turned to calibrate all
the preset LEDs will be lit. If, before depressing the ON/OFF pedal, one hits the SELECT pedal, the
light from the last preset selected turns on. Successive SELECT pedal depressions cycle through
all the preset LEDs. If only one preset LED is lit, then only that preset gets the new calibration data.
The remaining presets are unaffected, even if the last calibrate applied to all presets.

FREQUENCY Knob

MOTION

FLAILPICK
INVERT SENSOR
The FREQUENCY knob selects the frequency of sound on which the wah effect
acts most strongly. In more technical terms, the FREQUENCY knob specifies
the starting frequency of the filter sweep. Turning this clockwise will make
the wah sound higher and thinner, and turning it counter-clockwise will make
is sound darker and thicker.
Connections
SENSOR IN
Connect the Hot Hand here directly or using the supplied EXTENSION CABLE.
When the EFFECT knob is set to VOLUME SWELL, the FREQUENCY knob controls
the gain applied to the Hot Hand signals. Increasing the gain will allow you to
get larger volume changes with smaller motions of your hand.
ADVANCED USER NOTE
For information on how to adjust the gain of the Hot Hand signals for effects other than volume
swell, see the Hidden Feature and Controls section on page 20.
MOTION Knob/INVERT Sensor
The MOTION knob essentially determines how sensitive the Hot Hand is. Setting this knob towards “pick” will make the Hot Hand more sensitive so that
even the smallest motions will be picked up. Setting it to near “strum” is best
for strumming, and “flail” will reduce the sensitivity so that more dramatic
motions are required to produce a noticeable effect. Alternatively, the motion
knob can be thought of as setting the amount of “smoothing” of the Hot Hand
signal. “Pick” having the least smoothing, while “flail” has the most.
GUITAR IN
This is where you connect your guitar to the box, using a standard ¼-inch
guitar cable.
EXPRESSION IN
This input allows you to connect any standard expression pedal to the product. If the EXPRESSION IN and the Hot Hand are connected at the same time,
the control box will take the sum of their positions to control the wah. If the
Hot Hand is disconnected, then the pedal will have exclusive control and the
product will function like a traditional wah pedal.
Technical Note: The pedal needs to be a potentiometer, from 10K to 100K, with one side connected
to ring, and the other to ground, and the wiper connected to the tip of the TRS ¼-inch connector.
We have found that the Moog and M Audio EXP pedals work well.
SENSOR OUT
This output can be used to “pass on” the Hot Hand signal to future Source
Audio Hot Hand Products so that one Hot Hand Sensor will control multiple
effects. This application is also known as “Daisy Chaining”.
• WARNING! Do not connect this to any device other than the SENSOR IN jack
on another Source Audio product. Damage may result.
Turning the MOTION knob all the way around past the six o’clock position
causes the Hot Hand to invert its axis—up is down and down is up. When the
INVERT SENSOR light is off, the product is in normal mode (hand up boosts
higher frequencies), while on indicates inversion (hand up boosts lower
frequencies).
When the EFFECT knob is set to Auto-Wah, the Hot Hand signals are not used
and the MOTION knob controls the speed of the envelope follower.

EXPRESSION OUT
This jack allows you to send the Hot Hand control signals to other effects
devices that accept an expression input. This output signal defaults to an
analog voltage ranging from zero to 3.3VDC. This signal is “tip hot”. The maximum voltage can be adjusted up to 4.5VDC to accommodate other devices
that require higher voltages. For details on adjusting the voltage range see
the Hidden Features and Controls section on page 20. Note that this output
is active at all times when the Control Unit power is On. BE SURE TO READ
THE DOCUMENTATION ON ANY DEVICE YOU USE WITH THE HOT HAND IN THIS
CONFIGURATION.
9V DC
Connect a 9V DC power supply here if you do not wish to use batteries. Batteries will not be used while the power supply is connected. Power supply must
be REGULATED, minimum 200mA, and use a NEGATIVE tip plug. Use of a non-
Source Audio approved supply may cause damage and void the warranty. See
our website for a list of approved supplies, www.sourceaudio.net.

Hot Hand Theory of Operation
The PRESET feature of this product has been designed to be simple. This
product allows you to save 4 different configurations so that they may be easily recalled from the standing position. When you receive your product from
the factory, we have selected what we think are 4 useful configurations. You
may either keep these or replace any of them with your own settings. Should
you wish to return to the original factory presets, the configurations and other
ideas are located on our website, www.sourceaudio.net.
01 : Select and edit a preset
By stepping on the SELECT pedal you can select one of four user presets. Edit
a preset by changing values for FREQUENCY, EFFECT or MOTION. Any time that
you change the knob positions of a given preset, that LED will blink slowly to
indicate that the preset is being edited.
02 : Press and hold the SAVE button for two seconds
The LED will blink rapidly to signal that the saving process has begun. When
the light becomes solid, the save process is complete. Note that this process
will over-write any setting that we previously stored in this location.
ADVANCED USER NOTE
It is possible to save different calibration settings for each preset. The procedure is described in the
CALIBRATE section on page 10.
While it is certainly possible to use Hot Hand without much technical background, a few words about how it works will allow you to quickly understand
how hand position and hand motion impact the sound.
The Hot Hand sensor senses acceleration. This means that both hand
position and hand motion will cause the Hot Hand to react and send signals
to the control box.
Hand Position
Since gravity is an acceleration, the Hot Hand is always measuring the pull
of the Earth’s gravitational force. To illustrate this, try strumming a chord
and pointing your hand with the sensor attached straight at the ground. By
bending your arm at the elbow, slowly move your forearm up until your hand
is pointing at the ceiling. You should hear the filter sweep from low to high
following the position of your arm. When the INVERT light is on, the opposite
will be true and the same gesture will sweep the filter from high to low. You
don’t need to move your entire arm to accomplish this. The same effect can
be achieved changing your hand position by bending at the wrist or by leaning
back and moving your hand and the guitar together. Hand position can range
from subtle movement to the not so subtle. If subtlety is not your thing, dramatic motions will open the door for showmanship as your hand shapes the
sounds from your guitar. We must point out that the Hot Hand will respond
differently in Outer Space!
When you are using hand position and larger hand or arm motions to control
the Hot Hand, we recommend turning the MOTION knob towards FLAIL. This
will prevent the Hot Hand from responding to small variations and sounding
too “jittery”.
01 02
Hand Motion
In addition to measuring gravitational force, the sensor also measures
movement. The more the hand moves, the more the signal will change. To
illustrate this, strum a chord and shake your hand quickly. You should hear
the filter sweep back and forth following your hand motion. Experiment with
moving your hand in different directions and at different speeds to find the
method that works best for you. Use the MOTION knob to control how quickly
an effect will respond to your hand motion. In the most sensitive position
(PICK) the Hot Hand will detect even the slightest motion of the picking hand
and the result will sound like an auto-wah. In the STRUM position, the Hot
Hand will react more slowly. Try strumming some chords normally and listen
to how the Hot Hand reacts.

Following are descriptions of the different types of wah filters we programmed
into the Hot Hand box. Note that each sound interacts differently with both
the Hot Hand hand motions as well as the settings on the FREQUENCY and
MOTION knobs. It is suggested that one experiment a bit to find just the right
sound for different playing styles.
BAND PASS – LO
• Technical: Single Peak Band Pass Filter with low Q and parametric
equalization.
• Description: Simple band pass filter with a wide resonant peak at the center
frequency. Use the FREQUENCY KNOB to control the center frequency.
BAND PASS - HI
• Technical: Single Peak Band Pass Filter with high Q and parametric
equalization.
• Description: Simple band pass filter with a narrow resonant peak at the
center frequency. Use the FREQUENCY KNOB to control the center frequency.
MULTI-PEAK 01-04
• Technical: Various Advanced Multi-Peak Filter with multiple peaks and dips
moving in independent directions under Hot Hand control.
• Description: Each quite different. Some have phasing qualities and some
have more vocal characteristics. Give them a listen!
CLASSIC WAH
• Technical: Modified band pass filter
• Description: Classic wah pedals remain very popular and have a very well-
recognized sound. We have invested significant effort to model this sound in
our product. To be a true Classic Wah model, the FREQUENCY KNOB should
be set to the middle position.
LOW PASS - LO
• Technical: Single Peak Low Pass Filter with a low Q
• Description: Simple low pass filter with a wide resonant peak near the cutoff
frequency. Use the FREQUENCY KNOB to control the cut-off point.
LOW PASS - HI
• Technical: Single Peak Low Pass Filter with a high Q
• Description: Simple low pass filter with a narrow peak near the cutoff
frequency. Use the FREQUENCY KNOB to control the cut-off point.
AUTO-WAH
• Technical: Automatic Wah Filter
• Description: This effect is a typical auto-wah effect. The wah effect is
triggered by the amplitude of the guitar signal. Note that neither the Hot
Hand nor the EXPRESSION IN controls the signal in this mode. When the
EFFECT knob is set to Auto-Wah, the MOTION knob controls how quickly the
effect will react and reset.
VOLUME SWELL
• Technical: Volume Control or Tremolo
• Description: Use the Hot Hand to create volume swells as you raise (nor-
mal) or lower (INVERT SENSOR) your hand. Bounce or shake your hand to
create tremolo effects. The FREQUENCY knob controls how fast the volume
rises as you raise or move your hand. Note the calibration is very important
in this mode to establish the exact points where the fade begins/ends.

Hidden Features and Controls
We have tried to balance the conflicting requirements of flexibility and
simplicity in this unit. As such, most of the key features of the product are
found using the control knobs as they are labeled and defined in this manual.
However, we recognize that many of you will want to experiment beyond the
typical user, thus we have created a list of controls which are accessible via a
special start-up mode. To avoid getting into trouble, simply read the last point
in this section to get back to the factory settings.
To get into the special setup mode, power up the unit while holding down the
SELECT pedal and wait two seconds. The FREQUENCY and EFFECT knobs will
now reflect the current settings. This mode may be exited by power cycling
the unit (without depressing the pedal), or by turning the function selector to
the Calibrate position.
The EFFECT knob now chooses what special parameter to edit.
Accelerometer x and y-axis interchange
The Hot Hand sensor uses a two axis accelerometer. By default, the Hot
Hand senses acceleration along the x-axis. The x-axis runs parallel to your
arm and the long dimension of the sensor ring. The y-axis is perpendicular
to x, while still being in the plane of an outstretched hand wearing the ring.
We generally find that the x-axis gives better control than the y-axis, but feel
free to experiment, especially if your playing technique is somewhat unconventional. (Lefties—no, you still want to use x, but the normal and inverted
settings are effectively switched.)
Please note that if you are using the y-axis that you may need to re-calibrate
with your hand and the sensor parallel to the ground (palm down). This will
allow you to set a useful “zero” point for the y-axis.
The use of the x-axis sensor is indicated by the center LED. The next LED, in
either direction, indicates use of an axis midway between x and y (a 45 degree
angle.) Another step in either direction gets us to the y-axis. The complete set
of 9 choices, from counter-clock-wise:
• Calibrate: Exit special setup mode
• Classic: Input gain trim
• Low Pass Lo: Accelerometer gain trim
• Low Pass Hi: Accelerometer x and y axis interchange
• Band Pass Lo: Expression control output gain trim
• Band Pass Hi: Restore all special settings to default values
The FREQUENCY control will display the value of the selected parameter and
turning the knob will adjust the value. There are only 9 values per parameter; there are no in-between values. Once a value is changed it will be saved
automatically.
Input gain trim
This is a gain adjustment applied to the guitar signal immediately after A/D
conversion. The possible values are -8, -6, -4, -2, 0, 2, 4, 6, and 8 dB. Positive
values may be helpful for low level signals. If the input signal is particularly
hot, some attenuation may be required in order that the output of the filter
does not clip.
Accelerometer gain trim
This adjusts the gain multiplier applied to the Hot Hand signals relative to
the zero point from calibration. The lowest gain is .5, and the highest is 2.0.
The default of 1.0 is in the center position. The higher gains may be useful if
you like to use small hand motions and the lower gains if you prefer larger
hand motions.

The INVERT setting on the MOTION control will act to invert whichever axis
direction is chosen.
Expression control output gain trim
This allows adjustment of the level of the signal on the EXPRESSION OUT jack.
The default is position 2. This will result in a signal that varies between
zero and 3.3VDC. The maximum output voltage is 4.5VDC. Note that greater
changes in signal can also be produced by faster motion of your hand. Higher
gain will allow you to use slower motions to achieve the desired signal levels.
Check our website for additional usage tips, www.sourceaudio.net.
Restore defaults
When the EFFECT knob is set to restore (BAND PASS HI) in the special setting
mode, depressing the SELECT pedal will reset all of the special parameters to
their default settings.
