Owner's manual

The effect knob selects the type 
of phaser to be used. The effect 
knob also allows you to select the 
CALIBRATE mode for calibrating the 
signals from a Hot Hand sensor. See 
the Use with Hot Hand section for 
details on calibration.
The frequency knob sets the center 
frequency of the phaser sweep. Turn-
ing the knob counterclockwise will 
result in the phaser notches moving 
over lower frequencies. Turning the 
knob clockwise will result in the 
phaser notches moving over higher 
frequencies. This control is also use-
ful for adjusting the frequency range 
to match another instrument such 
as a bass guitar or keyboard.
The depth knob is a multi-purpose 
control on the Tri-Mod Phaser. It 
controls the depth of the effect and 
additionally controls the type of 
modulation being used. The control 
is broken down into two regions. To 
the left of the ‘0’ position (12 o’clock) 
the effect will be driven using an 
envelope follower. Turning the knob 
further to the left will increase the 
depth of the envelope. To the right 
of the ‘0’ position the effect will be 
driven using an 
LFO. Turning the 
knob further to the right will increase 
the depth of the 
LFO. This way you 
can easily switch back and forth 
between using the envelope or 
LFO to 
drive the effect. 
Note: If you plug a Hot Hand sensor 
in the 
SENSOR IN jack both the enve-
lope and 
LFO modes will be disabled 
and the unit will be put into Hot Hand 
Mode. See the Use with Hot Hand sec-
tion for more details.
In envelope mode, the speed knob 
controls the attack and decay time 
of the envelope with ‘-‘ being the 
slowest and ‘+’ being the fastest. In 
LFO mode, it controls the speed of 
the oscillator again with ‘-‘ being the 
slowest and ‘+’ the fastest. In Hot 
Hand mode, the knob controls the 
response of the motion sensor. See 
the Use with Hot Hand section for 
more details. 
Note: The envelope follower signal 
can be reset to zero by a very brief 
moment of silence, allowing the next 
note played to experience the full 
sweep of the envelope all the way 
from zero.
The ON/OFF switch engages or dis-
engages the effect. When the effect is 
engaged, the 
ON/OFF LED will be lit. 
The 
LED will be off in bypass mode. 
The 
ON/OFF switch is also used to 
start the calibration routine when the 
EFFECT knob is set to CALIBRATE. 
See the section on Use with Hot Hand 
for more details.
Here are some brief descriptions of 
the effects included in the Tri-Mod 
Phaser. The type of modulation used 
to control the effect, either Envelope, 
LFO, or Hot Hand, can create dramat-
ically different sounds for the same 
effect setting. We encourage you to 
experiment with different combina-
tions to nd what you like best.
 A model of one of the oldest 
rotating speaker simulators. 
2 notches, but one is such low 
frequency as to be nearly inaudible. 
No resonance.
Standard 2 notch. Some reso-
nance.
Standard 3 notch. No resonance.
Standard 4 notch. Some reso-
nance.
Standard 6 notch. Some reso-
nance.
6 notch, but shifted signal sub-
tracted from input rather than added. 
Produces a hollow sort of sound. 
No resonance. 
2 notch, but 6 peaks. More 
resonance.
12 notches. Why? Because we 
can. Hollow sound, more resonance.
3 notches, more resonance. 
The feedback loop that creates the 
resonance peaks has some extra 
delay in it, giving a more complicated 
frequency response curve, with 
more peaks.
6 notches, more resonance. 
Longer delay in feedback loop.
12 notches, more resonance, 
hollow sound. Very long delay in 
feedback loop.
Noise:
Low Power  Change batteries or plug in a DC power supply.
Near noise source  Move pedal away from power supplies and other   
  equipment.
Other equipment  Remove other effects from signal chain, 
  see if noise persists.
Bad cables  Swap out audio cables.
Low volume:
Low power  Change batteries or plug in a DC power supply.
Hot Hand doesn’t work:
Low power  Change batteries or plug in a DC power supply.
Not calibrated properly  Calibrate the Hot Hand (see Use with Hot Hand).
Not connected  Check Hot Hand connections.
Knobs don’t work /light up:
Low power  Change batteries or plug in a DC power supply.
Wrong power supply  Use correct power supply (see Quick Start).
Corroded input cable plug  Check input cable plug for corrosion on sleeve,   
  swap out cable if necessary.
TRS (stereo) cable used  Only use mono cable for input cable.

Dimensions
• L: 7 inches
• W: 4 inches
• H: 2 inches (including knobs)
Weight
• 1.25lbs
Power
• 110mA @ 9V DC (max 145mA 
 with Hot Hand Wireless Adapter)
• 15-20 hours battery life
• NEGATIVE tip power jack
Audio Performance

   To power the unit, insert 4 AA batteries (included) or connect a    
Source Audio SA150 9 Volt DC power supply to the 9V DC jack (A).
   Note: Power supply must be REGULATED, minimum 200mA, and use a 
negative tip plug. Use of a non-Source Audio power supply may cause 
damage and void the warranty.
   Next, plug your guitar (or other instrument) into the jack labeled 
GUITAR IN (B) via a standard ¼-inch cable. Connect your amp (or 
other audio device) to the GUITAR OUT (C) jack, again with a standard 
¼-inch cable. Both input and output are mono signals. 
   Note: The unit will not power up until a MONO ¼-inch plug is inserted into 
the guitar input. This is to conserve power when the unit is running on bat-
teries. Don’t forget to unplug the cable from the input when the unit is not in 
use—otherwise the batteries will continue to drain.
   To use your Tri-Mod Phaser with a Hot Hand sensor: Connect the 
sensor to the SENSOR IN (D) jack and follow any instructions sup-
plied with the sensor. The sensor input works with both wired and 
wireless sensors.
(see Controls section for more details) 
 • EFFECT selects desired effect type.
 • FREQUENCY adjusts the center frequency of the phaser. 
 • DEPTH controls the depth of the envelope (left of center) or 
the depth of the LFO (right of center).
 • ON/OFF engages and disengages the effect.
