Terminals marked with
this symbol carry
electrical current of
sucient magnitude to constitute risk
of electric shock. Use only high-quality
professional speaker cables with ¼" TS
or twist-locking plugs pre-installed.
Allother installation or modication
should be performed only by
qualiedpersonnel.
This symbol, wherever it
appears, alerts you to the
presence of uninsulated
dangerous voltage inside the enclosure
- voltage that may be sucient to
constitute a risk ofshock.
This symbol, wherever it
appears, alerts you to
important operating and
maintenance instructions in the
accompanying literature. Please read
themanual.
Caution
To reduce the risk of
electric shock, do not
remove the top cover (or the rear
section). No user serviceable parts inside.
Refer servicing to qualiedpersonnel.
Caution
To reduce the risk of
re or electric shock, do
not expose this appliance to rain and
moisture. Theapparatus shall not
be exposed to dripping or splashing
liquids and no objects lled with
liquids, such as vases, shall be placed
on the apparatus.
Caution
These service instructions
are for use by qualied
service personnel only. Toreduce
the risk of electric shock do not
perform any servicing other than that
contained in the operation instructions.

apparatus combination to avoid injury
from tip-over.
13. Unplug this apparatus during
lightning storms or when unused for
long periods of time.
14. Refer all servicing to qualied
service personnel. Servicing is required
when the apparatus has been damaged
in any way, such as power supply cord

appliance coupler is used as the
disconnect device, the disconnect
device shall remain readily operable.
17. Correct disposal of
this product: This
symbol indicates that
this product must not
be disposed of with
household waste, according to the
WEEE Directive (2012/19/EU) and your
national law. This product should be
taken to a collection center licensed for
the recycling of waste electrical and
electronic equipment (EEE).
The mishandling of this type of waste
could have a possible negative impact
on the environment and human health
due to potentially hazardous
substances that are generally
associated with EEE. At the same time,
your cooperation in the correct disposal
of this product will contribute to the
ecient use of natural resources. For
more information about where you can
take your waste equipment for
recycling, please contact your local city
oce, or your household waste
collection service.
18. Do not install in a conned space,
such as a book case or similar unit.
19. Do not place naked ame
sources, such as lighted candles,
on the apparatus.
20. Please keep the environmental
aspects of battery disposal in mind.
Batteries must be disposed-of at a
battery collection point.
21. This apparatus may be used in
tropical and moderate climates up
to 45°C.

para constituir un riesgo de descarga
eléctrica. Utilicesolo cables de altavoz
profesionales y de alta calidad con
conectores TS de 6,3 mm o de bayoneta
prejados. Cualquier otra instalación o
modicación debe ser realizada
únicamente por un técnicocualicado.
Este símbolo, siempre que
aparece, leadvierte de la

Este símbolo, siempre que
aparece, leadvierte sobre
instrucciones operativas y
de mantenimiento que aparecen en la
documentación adjunta. Por favor,
leaelmanual.
Atención
Para reducir el riesgo de
descarga eléctrica, no
quite la tapa (olaparte posterior).
Nohay piezas en el interior del equipo
que puedan ser reparadas por el
usuario. Sies necesario, póngase en
contacto con personal cualicado.
Atención
Para reducir el riesgo
de incendio o descarga
eléctrica, no exponga este aparato a la
lluvia, humedad o alguna otra fuente
que pueda salpicar o derramar algún
líquido sobre el aparato. Nocoloque
ningún tipo de recipiente para líquidos
sobre elaparato.
Atención
Las instrucciones

contactos: dos polos y la puesta a
tierra. El contacto ancho y el tercer
contacto, respectivamente, son los que
garantizan una mayor seguridad. Si el
enchufe suministrado con el equipo
no concuerda con la toma de corriente,
consulte con un electricista para
cambiar la toma de corriente obsoleta.
10. Coloque el cable de suministro de

o accesorios especicados por
el fabricante.
12. Use
únicamente la
carretilla,
plataforma,
trípode, soporte o
mesa especicados
por el fabricante o suministrados junto
con el equipo. Altransportar el equipo,
tenga cuidado para evitar daños y
caídas al tropezar con algún obstáculo.
13. Desenchufe el equipo durante
tormentas o si no va a utilizarlo durante
un periodo largo.
14. Confíe las reparaciones
únicamente a servicios técnicos
cualicados. La unidad requiere
mantenimiento siempre que haya
sufrido algún daño, si el cable de
suministro de energía o el enchufe
presentaran daños, sehubiera
derramado un líquido o hubieran caído
objetos dentro del equipo, si el aparato
hubiera estado expuesto a la humedad
o la lluvia, si ha dejado de funcionar de
manera normal o si ha sufrido algún
golpe o caída.
15. Al conectar la unidad a la toma de
corriente eléctrica asegúrese de que
la conexión disponga de una unión
atierra.
16. Si el enchufe o conector
de red sirve como único medio
de desconexión, éste debe ser
accesiblefácilmente.

high pass lter CUTOFF FREQ input).
(20) MG/T.EXT - adjust the amount of cuto frequency
modulation of the low-pass lter by the modulation
generator (MG) or T.EXT (if a connection is made to the
TOTAL input).
(21) EG2/EXT - adjust the amount of cuto frequency
modulation of the low-pass lter by envelope 2 (EG2) or
EXT (if a connection is made to the low-pass lter CUTOFF
FREQ input).
MIDI IN Section
(22) MIDI IN - this 5-pin DIN jack receives MIDI data from an
external source. This will commonly be a MIDI keyboard,
an external hardware sequencer, a computer equipped
with a MIDI interface, etc.
Modulation Generator Section
(23) LED - indicates the current rate of the
modulation generator.
(24) WAVEFORM - adjust the waveform of the modulation
generator from reverse sawtooth, through triangle, to
sawtooth. It also aects the second available waveform
from wide, square, to narrow.
(25) FREQUENCY - adjust the frequency of the modulation
generator from 0.1 to 22 Hz. The generator is also known
as a low frequency oscillator (LFO).
Envelope Generator Section
Envelope 1 aects the frequency modulation.
Envelope 2 aects the cuto frequency modulation,
as well as the amplitude modulation of the voltage
controlled amplier (VCA).
(26) DELAY TIME - controls the time between the arrival of the
trigger signal and the start of the attack time.
(27) ATTACK TIME - controls the time it takes for envelope 1 to
reach a maximum level after a note is played.
(28) RELEASE TIME - controls the release time of envelope 1
after the note is released.
(29) HOLD TIME - controls the amount of time that the trigger
signal is held (extended).
(30) ATTACK TIME - controls the attack time of envelope 2.
