FREQUENCY Knob

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.

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

MOTION Knob/INVERT Sensor

The

MOTION

knob essentially determines how sensitive the Hot Hand is. Set-

ting 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.

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.

Connections

SENSOR IN

Connect the Hot Hand here directly or using the supplied

EXTENSION CABLE

.

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 prod-
uct. 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.
