Troubleshooting If there seems to be a problem with your 1201, please check
the followingpoints first.
❒ Specifications
❒ Safety Precautions
In this manual, symbols are used to highlight
warnings and cautions for you to read so that
accidents can be prevented. The meanings of these
symbols are as follows:
This symbol indicates explanations
about extremely dangerous matters. If
users ignore this symbol and handle the
device the wrong way, serious injury or
death could result.
This symbol indicates explanations
about dangerous matters. If users
ignore this symbol and handle the
device the wrong way, bodily injury and
damage to the equipment could result.
Please observe the following safety tips and
precautions to ensure hazard-free use of the 1201.
■ Power requirements
The 1201 is powered by the supplied AC
adapter . To prevent malfunction and safety
hazards, Do not use any other kind of AC
adapter.
When using the 1201 in an area with a
different line voltage, please consult your
local ZOOM distributor about acquiring a
proper AC adapter.
■ Environment
Avoid using your 1201 in environments where
it will be exposed to:
• Extreme temperature
• High humidity or moisture
• Excessive dust or sand
• Excessive vibration or shock
■ Handling
The 1201 is a precision instrument. Do not
exert undue pressure on the unit.
Also take care not to drop the unit, and do not
subject it to shock or excessive pressure.
■ Connecting cables and input and
output jacks
You should always turn off the power to the
1201 and all other equipment before
connecting or disconnecting any cables. Also
make sure to disconnect all cables and the AC
adapter before moving the 1201.
■ Alterations
Never open the case of the 1201 or attempt to
modify the product in any way since this can
result in damage to the unit.
❒ Usage Precautions
■ Electrical interference
The 1201 has been designed to minimize radio
frequency emissions and is highly resistant to
external interference. However, if placed very
close to equipment such as TV sets or radio
receivers, reception interference may occur. If
you encounter problems, move the 1201 further
away from the affected equipment.
Whatever the type of digital control device, the
1201 included, electromagnetic damage can
cause malfunctioning, and can corrupt or
destroy data. Since this is an ever-present
danger, thorough care should be taken to
minimize the risk of damage.
■ Cleaning
Use a soft, dry cloth to clean the 1201. If
necessary, slightly moisten the cloth. Do not use
abrasive cleanser, wax, or solvents (such as
paint thinner or cleaning alcohol), since these
may dull the finish or damage the surface.
Please keep this manual in a convenient place
for future reference.

❒ Rack Mounting
This product conforms to EIA and DIN specifications for 19-inch rack mounting. We recommend to
mount the unit in a rack rather than just placing it on a table or similar. As shown in the illustration,
fasten the unit securely in the rack, using the four screw holes.
• This unit uses a metal enclosure and is heavier than it might seem at first glance.
When mounting in a rack, firmly support the unit and do not let go until all
screws have been fastened. If the unit is not secured properly, it can fall and cause
damage and injury.
• Do not stack the unit directly on top of other components. Otherwise overheating
poses a risk of fire and can lead to performance degradation.
• Before moving the unit, disconnect the AC adapter and all other cables.
Otherwise cables or equipment may be damaged.
• Use a sturdy rack and place it on a level, solid surface where there is no danger of
the rack vibrating or falling. Otherwise injury to persons or damage to equipment
may occur.

❒ Controls and Functions
■ Front Panel
(1) INPUT level control
Adjusts the level of the input signal from an instrument or other
program source.
(2) LED indicator
When the 1201 is turned on, this indicator lights up in green. If the input
signal exceeds the peak level, the indicator lights up in red and the
sound will be distorted. Adjust the INPUT level control so that the
indicator flashes only very briefly at the highest signal peaks. When
effects were turned off with the optional foot switch FS01, the indicator
flashes in orange.
(3) MIX control
Adjusts the ratio between original sound and effect sound. Turning the
control towards DRY (counterclockwise) emphasizes the original sound
and turning it towards WET (clockwise) emphasizes the effect sound.
(4) OUTPUT level control
Adjusts the output signal level.
(5) CHARACTER/VARIATION selector
◆ When bank A is selected with the BANK switch:
Selects the reverb character.
◆ When bank B or C is selected with the BANK switch:
Selects the effect variation.
For each effect,11 character or variation settings are available.
(6) REVERB TIME/ADJUST control
◆ When bank A is selected with the BANK switch:
Adjusts the reverb time.
◆ When bank B or C is selected with the BANK switch:
Adjusts a specific effect parameter. Which parameter is adjusted
depends on the currently selected effect.

(1) INPUT jacks
Serve for connection to the sound source, such as the send jacks of an
instrument or mixer. Mono sources should be connected to the
L/MONO jack and stereo sources to both jacks (L/MONO for left
channel and R for right channel).
Note: A preamplifier (such as integrated in a mixer) or a compact effect
device is required when wishing to use the 1201 with an instrument
with low output level, such as an electric guitar or bass, or with a
high-impedance instrument (470 kilohms or higher).
(2) OUTPUT jacks
Serve for connection to the return jacks of an instrument or mixer, or to
recording/playback equipment.
(3) EFFECT ON/OFF jack
The optional foot switch FS01 can be connected here, for switching
effects on and off with your foot. When effects are off, only the original
sound is heard and the front- panel LED indicator flashes in orange.
(4) DC INPUT jack
The cable from the supplied AC adapter is connected here.
Note: When the AC adapter is plugged into an AC outlet, the 1201 is
automatically turned on.
■ Rear Panel
(7) REVERB TYPE/EFFECTS selector
◆ When bank A is selected with the BANK switch:
Selects the reverb type.
◆ When bank B or C is selected with the BANK switch:
Selects the effect type from each bank.
For each bank, 11 settings are available, resulting in a total of 33 reverb
and effect types.
(8) BANK switch
Selects one of the three effect banks (A, B, C). A bank is a group of
related effects. Bank A contains reverb type effects and banks B and C
contain modulation and multi-effect settings.
❒ Connections
Connect an electronic instrument, microphone, mixer, or other audio equipment to the 1201 as
described below.
Before making any connections, set the power switches of all equipment to OFF.
If the equipment is on, sudden noise surges can lead to hearing damage or damage
to the equipment.

■ Connection between sound source such as electronic instrument or CD
player and playback equipment
This connection example shows the use of the 1201 as an effect device for electronic instruments.
When using the unit in a monaural configuration, connect only the L/MONO jack. The balance
between the original sound of the instrument and the effect sound is adjusted by the MIX level control.
When wishing to apply an effect such as KARAOKE to stereo sources, a CD player can be connected
instead of an electronic instrument. (The KARAOKE effect only works with stereo sources.)
■ Connection to send/return jacks of a mixer
This connection example shows the use of the 1201 in the send/return loop of a mixer to which
instruments or other sound sources are connected. In this case, the balance between the original sound
of the mixer (DRY) and the effect sound
produced by the 1201 (WET) is normally
adjusted at the mixer. Therefore the MIX
LEVEL control of the 1201 should be
turned fully clockwise, so that only the
WET sound is returned to the mixer.
■ Connection for use of the Vocoder effect
When the Vocoder effect is selected, the R input signal is used to create an envelope, and the effect
itself is applied to the L/MONO input signal. Therefore the microphone (via a microphone amplifier
or mixer) should be connected to the R jack and the keyboard or guitar signal to the L/MONO jack.
When connections have been made in this way, talking or singing into the microphone will alter the
instrument sound according to the voice envelope curve (Vocoder effect).
■ Using two effects in parallel
The 1201 allows the simultaneous use of two effects in parallel. This is possible with the effects in
bank B marked with a "/" on the display. This connection example shows how to use such effects
independently in a parallel configuration.
