Zoom RFX-1000 User manual

Thank you for selecting the ZOOM RFX-1000 (hereafter simply called the "RFX-
1000 "). The RFX-1000 is a sophisticated digital reverb and multi-effect processor with
the following features and functions.
Please take the time to read this manual carefully so as to get the most out of your RFX-
1000 and to ensure optimum performance and reliability. Retain this manual, the
warranty card and all other documentation for future reference.
• 33 immediately usable effects
The RFX-1000 comes with a full complement of preset effects (11 effects x 3 banks).
Right out of the box, the unit is ready to create great sound. The REVERB bank in
particular provides a wide spread and natural sounding ambience that meets even
demanding professional standards.
• Built-in professional quality reverb
The reverb effects alone allow 121 different settings. The convincing sound stage
created by the RFX-1000 far surpasses anything else available in this class.
• Innovative choices
Lo-Fi EFX purposely degrades sound quality for special effect. RESONANCE
processes the input signal with sophisticated filtering. MIC SIMULATOR produces
condenser mic sound from a dynamic microphone. These and various other effects
are great for recording and give full scope to your creativity.
• Attractive mixdown effects
Mixdown effects can be used effectively to tailor the overall mood of a song when
performing mixdown (mixing multiple tracks onto two final stereo tracks) or
mastering (fine-tuning the sound and level of a final 2-track mix).
• Intuitive editing controls
Convenient knobs on the front panel let you directly adjust items such as the mixing
ratio of original sound and effect sound. Editing effect parameters on the fly is also
easy and straightforward. This allows quick fine-tuning for optimum sound.
• MIC IN jack
The dedicated microphone jack on the front panel comes in handy for creating vocal
effects without having to make cumbersome connections in the rear. Controlling the
VOCODER effect is a snap thanks to this feature.

(1) POWER switch
Serves to turn the unit on and off.
(2) POWER indicator
When the RFX-1000 is on, this LED indicator is lit in
green. When the foot switch FS01 (option) was used
to switch the effects off, the indicator flashes red.
(3) MIC IN jack
A dynamic microphone with an output impedance of
about 600 ohms can be connected here. Normally the
input signal from this jack is mixed with the signal
from the rear-panel INPUT jacks. When the
VOCODER effect is selected, the mic input signal
serves for controlling the effect. You can use your
voice to alter the sound character and the envelope
(volume change curve).
Note: When plugging or unplugging a
microphone here, noise may occur. Be sure
to turn down the INPUT control (5) first.
(4) Level meter
These indicators show the signal input level.
(5) INPUT control
Serves to adjust the signal from the INPUT jacks and
the MIC IN jack.
(6) OUTPUT control
Serves to adjust the level of the signal supplied at the
OUTPUT jacks.
(7) MIX control
Serves to adjust the balance between original sound
(DRY) and effect sound (WET). When the control is
turned fully counterclockwise, only the original sound
is output. When the control is turned fully clockwise,
only the effect sound is output.

This is an example for inserting the RFX-1000 between the sound source and a playback system or multi-track recorder
(MTR). A stereo source should be connected to the INPUT L/MONO and R jacks. A mono source should be connected to
the L/MONO jack only.
In this example, the signal from the mic or the instrument is effect processed by the RFX-1000 and then sent to the
playback system or MTR. The balance between original sound and effect sound is adjusted at the RFX-1000.
Insert Connection
Basic Connections
The RFX-1000 is compatible with international 19-inch rack standards (EIA, DIN). Because the unit has been designed
for rack installation, it is preferable to operate the unit in this way, rather than simply placing it on a table or similar.
Align the four screw holes with the rack screw holes and securely fasten the unit to the rack with screws.
•The RFX-1000 uses a metal frame,
making the unit heavier than it might
seem at first glance. While installing the
unit in a rack, carefully support the
weight of the unit until all screws are
securely tightened. Otherwise the unit
may drop, possibly causing injury to
persons or damage to itself or to other
equipment.
•Do not directly stack the unit on top of
other equipment. Otherwise heat may
lead to a fire risk or cause performance
degradation.
•Before installation, always unplug any
connecting cables and the AC adapter cable.
Otherwise the equipment or the cables may be
damaged.
•Make sure that the rack in which the unit is
installed is placed on a firm, solid surface, so
that it cannot shake or topple over. Otherwise
there is a risk of injury to persons or damage
to the unit or to other equipment.

This is a connection example for using the VOCODER effect from the MIX&SFX bank. Connect a dynamic microphone
to the front-panel MIC IN jack on the RFX-1000. Connect a synthesizer or other instrument to the rear-panel INPUT
L/MONO jack. You can then use the mic to vary the envelope (volume change curve) and the sound character of the
VOCODER effect. Instead of the mic, it is also possible to use the right- channel signal for controlling the effect. In this
case, the signal supplied to the INPUT L/MONO jack is controlled by the signal supplied to the INPUT R jack.

Usage Precautions
•Electrical interference
The RFX-1000 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 RFX-1000 further away from the affected
equipment.
Whatever the type of digital control device, the RFX-
1000 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 RFX-1000. 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.
