Thank you for selecting the ZOOM RFX-1100 (hereafter simply called the "RFX-
1100
"). The RFX-1100 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-1100 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-1100 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-1100 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 connector
The MIC IN connector on the front panel serves as an additional input for a
microphone. This is convenient for applying effects to a vocal part and for
controlling the VOCODER effect with your voice.

(1) MIC IN connector
A dynamic microphone with an impedance of about
600 ohms can be connected here, for use as an
additional input source. Either an XLR plug (balanced
connection) or a phone plug (balanced/unbalanced
connection) can be used.
Normally the input signal from this connector is
mixed with the signal from the rear-panel INPUT
jacks. When the VOCODER effect is selected, the
signal from this connector serves for controlling the
sound character and the envelope (volume change
curve) of the VOCODER effect.
(2) MIC ON/OFF switch
This switch turns the signal from the MIC IN
connector on and off.
* Before inserting or removing the plug of a
microphone into and from the MIC IN connector, be
sure to set the MIC ON/OFF switch to OFF.
(3) MIC IN indicator
When the MIC ON/OFF switch is ON, this indicator
lights up.
(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-1100 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-1100 and then sent to the
playback system or MTR. The balance between original sound and effect sound is adjusted at the RFX-1100.
Insert Connection
Basic Connections
The RFX-1100 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-1100 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 power 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.

RFX-1100 to the return jacks (or the stereo line input jacks) of the mixer or MTR.
In this configuration, the RFX-1100 should be set so that it outputs only the effect sound, and the balance between
original sound and effect sound should be adjusted at the mixer or multi-track recorder. Supplying the send signal to the
RFX-1100 in stereo is also possible.

Using Two Effects in Parallel
The RFX-1100 allows using two effects at the same time (in parallel). This is possible with effects from the EFFECTS
bank which have a double name separated with a slash ("/"). The following illustration shows a connection example for
using two effects independently in the left and right channel.
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-1100. 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. Verify
that the MIC IN indicator is lit. If not, press the MIC ON/OFF switch so that the indicator comes on.
