Cord Hook
Loop the AC adaptor cord around
this hook; this will help prevent
damage to the cable and help pre-
vent accidental disconnection.
* To prevent the inadvertent disrup-
tion of power to your unit (should
theplugbepulledoutaccidentally),
and to avoid applying undue stress
to the AC adaptor jack, anchor the
power cord using the cord hook, as
shown in the illustration.
LINE OUT L/R Jacks
These are output jacks (stereo, RCA phono type) for connecting the output of
the VT-1 to the line input jacks of an external device.
INPUT Jack
This is an (unbalanced) input jack
for connecting a microphone, etc.
* Howling could be produced depend-
ing on the location of microphones
relativetospeakers.Thiscanberem-
edied by:
1. Changing the orientation of the
microphone(s).
2. Relocating microphone(s) at a
greater distance from speakers.
3. Lowering volume levels.
REMOTE Jack
This jack is for connecting a foot
switch (BOSS FS-5L; optional). A
foot switch allows you to turn the
voicecharacterfunctionon/offwith-
out affecting the reverb component.
AC Adaptor Jack
Connect the included AC adaptor
(ACI/ACB Series) to this jack.
Number Buttons / Number Indicators
These buttons are used to select memory positions 1 –4;
the indicator of the selected number will light.
When you move the sliders or press the ROBOT button,
the number indicator will blink to indicate that the voice
characterisnowdifferentthanthecontentsofthememory.
ROBOT Button /
Robot Indicator
Thisbutton turnstheRobot func-
tion on/off. When the Robot
function is on, the Robot indica-
tor will light.
When the Robot function is on,
thevoice will be outputat a fixed
pitch (regardless of the input
pitch), producing a flat voice
character without intonation.
WRITE Button
This button is used to write (store) the
currentvoicecharactersettingsintomemory
(the USER bank).
Write procedure
Here’s how to write a voice character that
you’ve created into memory (USER bank).
By storing a voice character in memory, you
can later re-select it at the touch of a button.
1. Move the sliders and/or press the RO-
BOT button to create the desired voice
character.
2.
Press the WRITE button. The bank
(USER)andnumberindicators willblink.
3. Press a number button (1 –4) to select
the desired storage destination; the
number indicator will blink.
4. Press the WRITE button once again.
The voice character will be stored in the
number you selected in step 3.
* BypressingtheWRITEbuttonwithoutmov-
ing the sliders or pressing the ROBOT but-
ton, you can copy the currently selected
voice character to another USER number.
* If during the Write procedure you decide to
cancel the operation, hold down the BY-
PASS button and press the WRITE button.
You will return to where you were before
starting the Write procedure.
FORMANT Slider
Formants are fixed frequency regions of
emphasis that are an important element
in determining how a voice sounds. This
slider adjusts the formants. Raising the
slider produces a voice character that
soundsas if the vocal cords havebecome
‘smaller.’Lowering the slider produces
a voice character that sounds as if the
vocal cords have become ‘larger.’
PITCH Slider
This slider adjusts the pitch of
the voice character. The pitch
can be adjusted over a range of
+/- one octave.
MIX BALANCE Slider
This slider adjusts the volume
balance between the generated
voice character and the original
input sound. As the slider is
raised (toward the EFFECT end
of the scale), the generated voice
character will become louder.
Bank Buttons / Bank Indicators
These buttons are used to select memory banks; they switch between the
Preset bank and the User bank.
Preset bank: Thisbankcontains preset voice characters. It is not possible
to re-write the contents of these memories.
User bank: Voice characters that you create using the sliders and the
ROBOT button can be stored in these memories.
PEAK Indicator
This indicator lets you check the
microphone input level. If the
indicatorlightsfrequently,lower
the input level by adjusting the
INPUT LEVEL knob located on
the rear panel.
* The PEAK indicator will light 6
dB below the clipping point (the
level at which distortion will
begin).
* If the PEAK indicator lights too
frequently, the proper effect will
not be obtained.
BYPASS Button / Bypass Indicator
This button switches the bypass function
on/off.
When bypass is on, the BYPASS indicator
willlight, and the voice character and reverb
will be turned off so that the input sound is
output without change.
If you use the REMOTE jack to turn off the
voice character (while leaving the reverb
unaffected), the Bypass indicator will blink.
REVERB Slider
This slider adjusts the
volume of the reverbera-
tion sound.
Selecting Preset Memories
You can choose from five voice character types as appro-
priate for your musical or performance situation. The voice
character memories will be given settings of the selected
type. At this time, the contents of the USER bank will also
be re-written.
If All Memory Type is selected, you will be able to freely
modify the settings of the PRESET bank just as with the
USER bank.
(Procedure)
1. Turn the power off.
2. While holding down the button for the desired type,
turn the power on again.
3. While the Preset indicator and the User indicator are lit,
press the WRITE button.
The voice character memories will be given settings of
the selected type:
{ [BANK]: Standard Settings }
{ [1]: Vocal Applications with reverb }
{ [2]: Vocal Applications with non-reverb }
{ [3]: Narrations / DJ Performance Settings }
{ [4]: Animation Character Settings }
{ [ROBOT]: All memory types }
Main Features
A vocal effector that independently controls
basic pitch and formants
When pitch is shifted using a conventional pitch shifter, the
formants (regions of spectral emphasis determined by the
size of the vocal cords) are also shifted. This means that
raising the pitch produces a “chipmunk voice,”as if the
vocal cords had become smaller. Conversely, lowering the
pitch produces a “giant voice,”as if the vocal cords had
become larger.
The VT-1 controls basic pitch and formants independently,
allowing a variety of voice characters (characteristic types
of voice) to be created.
Special effects using the ROBOT button
The ROBOT button fixes the vocal pitch to produce a
special effect like that of a robot speaking.
Memory Function
Voice character settings can be stored in memory. At the
touch of a button, you can select User voice characters or
Presetvoicecharacterstoswitch between a variety of sounds.
High-Quality Reverb
The on-board reverb is of a quality that rivals dedicated
reverb processors; the ideal reverb for your vocal part is
always be available.
REMOTE Jack
A REMOTE jack is provided, allowing you to turn the voice
character function on/off with a foot switch, without
affecting the reverb.
Hints for voice input
–Input only a single voice. If several voices are input, the
VT-1 will not operate properly.
–Be sure that sound from a speaker does not enter the
microphone you are using. This will have the same
effect as if several voices were input to the unit (i.e. the
VT-1 will not function properly).
–We recommend that you use a unidirectional micro-
phone; speak or sing as close to the microphone as
possible.

INPUT LEVEL Knob
This knob adjusts the input level. Set this
knob so that when the input voice is at its
loudest, the PEAK indicator lights briefly.
* The input level must be adjusted carefully.
If the PEAK indicator lights too frequently
or not at all, the correct effect will not be
obtained.
POWER Switch
This switch turns the VT-1 on/
off.
* This unit is equipped with a
protection circuit. A brief inter-
val (a few seconds) after power
up is required before the unit
will operate normally.

This is an output jack (mono,
unbalanced) for connecting the
output of the VT-1 to the micro-
phone input jack of an external
device.
