 QUICK START GUIDE 

 

This Quick Start Guide will help you get started using your Stereo Talking 

Machine immediately. For detailed information on all of the Stereo Talking 

Machine's features and f

unctions, please refer to the rest of this owner’s manual.

 

 

Setup 

1.

 

Using an unbalanced instrument cable, plug the output of your instrument 

into the INPUT jack on the right side of the STM. 

2.

 

Connect an unbalanced instrument cable from the MONO/L output jack  on 

the left side of the STM to the input jack of an amplifier. 

3.

 

Connect  the  included  AC  Adaptor  to  a  wall  outlet  and  plug  its  barrel 

connector into the 9V power jack at the top of the STM. 

4.

 

Turn  on  the  amplifier  and  turn  up  your  instrument’s  volume.  Press  th

BYPASS footswitch so that the STATUS LED is lit; the STM is now activated. 

 

A. Preset Settings 

 

Press and release the PRESET footswitch to cycle through the STM’s preset 

settings. Each factory preset has been carefully prepared to utilize the deep 

sonic capabilities of the STM. You may overwrite the factory presets with 

your own sound creations whenever you like. 

 

 

B. Manual Settings

 

1.

 

To begin, turn the STM’s knobs to the following positions:

 

BLEND: 

Full Clockwise 

VOICE: 

Full Clockwise (OW-EE) 

ATTACK: 

12 

o’clock

 

DECAY: 

12 o’clock

 

SENSITIVITY: 

1 o’clock

 

2.

 

Ensure  the  PRESET  LED  (bottom  left)  is  off.  If  it  is  on,  turn  the  white 

PRESETS  knob  clockwise  until  the  PRESET  LED  shuts  off.  This  action 

deactivates the currently loaded preset. 

3.

 

Ensure  the  auxiliary  functions  (indicated  by  the  leftmost  orange  LED)  are 

off. If they are on, press the white PRESETS knob to deactivate them. 

4.

 

Play  your  instrument  at  the  intensity  you  would  like  to  trigger  the  filter 

sweep. While playing, turn up the SENSITIVITY knob until the Sweep Level 

LEDs light up completely after each note you play. 

5.

 

To  change  the  sweep  speed  of  the  filters,  adjust  the  ATTACK  and  DECAY 

knobs. 

6.

 

Adjust the VOICE knob to try different voicings or filter types. 

 

 

 SWEEP LEVEL LEDs 

 

The two rightmost orange LEDs under the PRESETS knob indicate the position 

of the filters at any given moment. When the LEDs are both unlit, the filters are 
at their rest position (ex: set to OW for the positive OW-EE voice). When the 

LEDs are both lit, the filters are in their maximum position (ex: set to EE for the 
positive  OW-EE  voice).  The  LEDs  sweep  on  and  off,  visually  representing  the 

audible sweep of the filters as the input signal triggers the envelope sweep, the  
expression  pedal  manually  moves  through  the  filters  or  as  the  internal  LFO 

automatically modulates the filters.
