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.

Technical Note: The input impedance is 2.2 M. The maximum signal should not exceed 4.2 volts
peak-to-peak.

EXPRESSION IN

This input allows you to connect any standard expression pedal to the product
The

EXPRESSION IN

signal is summed with the Hot Hand, when the

MOD

SOURCE

is set to Hot Hand. If the Hot Hand is disconnected, then the pedal

will have exclusive control. If the

MOD SOURCE

is set to

LFO

, the

EXPRESSION

IN

signal will control the

LFO

speed.

EXPRESSION IN

is unused when the

MOD

SOURCE

is set to

ENVELOPE

.

Technical Note: The pedal needs to have a linear taper 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. Audio taper pots,
as commonly found in volume control pedals, will not give good results.

Very Technical Note: An external control voltage source, such as from an analog synthesizer, may
be connected to the

EXPRESSION IN

jack. A mono ¼-inch cable may be used for this application. Do

not allow the input voltage to go negative with respect to ground.

SENSOR OUT

This output can be used to “pass on” the Hot Hand signal to other Source
Audio Hot Hand Products (such as the Motion Controlled Wah Filters) 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.

GUITAR OUT

This ¼-inch output is where you connect your amp or the next pedal in
your chain.

EXPRESSION OUT

This jack allows you to send the Hot Hand control signals, or whatever modu-
lation has been selected by the

MOD SOURCE

control, to other effects devices

that accept an expression input. This output signal defaults to an analog volt-
age ranging from zero to

3.3VDC

. This signal is “tip hot”. The maximum volt-

age can be adjusted up to

4.5VDC

to accommodate other devices that require

higher voltages. For details on adjusting the voltage range see the Back Page
Parameters section on page 24. 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. Bat-

teries will not be drained while the power supply is connected. Power supply
must be

REGULATED

, minimum

200mA,

and use a

NEGATIVE

tip plug. A negative

tip plug is generally indicated by the symbol on the power supply.

Use of a non-Source Audio approved supply may cause damage and void the
warranty.
