Input Gain Control: This control sets the signal level to the equalizer. It is capable of -12dB
to +12dB of gain. Its effect is apparent by viewing the OUTPUT LEVEL BAR GRAPH.
EQ Bypass: This switch removes the graphic equalizer section from the signal path. The
BYPASS switch does not, however, affect the INPUT GAIN, AFS, or LOW CUT filters. This button lights red when the EQ is in bypass mode
Boost/Cut Range Selection Switch: This switch selects which of the two boost/cut ranges the
equalizer will use, either ±6dB or ±15dB. The button lights red when the ±15dB range is selected.
Output Level Bar Graph: These four LEDs indicate output level of the equalizer. It monitors
the level at the output of the equalizer after all other processing, including the limiter.
Clip LED: This LED lights whenever any internal signal level reaches 1dB below clipping which
may occur when any of the following happen: 1) the input signal is “hotter” than +20dBu, 2)
excessive gain is applied by the input gain control, or 3) excessive boost is applied using the
frequency sliders.
Gain Reduction Meter: These four LEDs indicate the amount of gain reduction being induced
by the setting of the PeakStopPlus
®
LIMITER THRESHOLD control as the signal level from the
graphic EQ section exceeds this limiter threshold setting.
PeakStopPlus®Limiter Threshold Control: This control engages the PeakStopPlus™ limiter.
It sets the threshold level at which ∞:1 gain reduction will begin to occur. It is capable of a
range of 0dBu through “OFF” (+20dBu). When the threshold control is set to “OFF”, the limiter
is effectively disabled, and no gain reduction will occur.
AFS™ (Advanced Feedback Suppression) Switch: This control engages the AFS function of
the iEQ 15 and 31 If AFS is Off, the filters are bypassed, and the algorithm is halted (the filters
are not updated). If AFS is On, the filters are activeThe AFS modes are as follows:

The iEQ 15 and 31 offer the exclusive patent pending AFS (Advanced Feedback Suppression)
feedback elimination module. The AFS uses Precision Frequency Detection and state-of-the-art
processing to determine the exact portions of a given frequency of your feedback that need to
be removed (instead of taking out large sections of your sound). For more detailed information regarding AFS, please visit the AFS white paper section at www.dbxpro.com.
The AFS module of the iEQ 15 and 31 allow the user to optimize the elimination of feedback.
In the past, graphic equalizers were used to eliminate feedback from a system. This was an
acceptable method for eliminating feedback, but when this method was precision tested, the
result clearly showed that a single 1/3 octave EQ slider was removing approximately half of the
signal power. With the AFS, the module removes the feedback automatically and the proprietary, precision AFS filters remove only a fraction of the frequency spectrum. The following
diagram shows AFS as opposed to competing, competitive feedback eliminators and conventional
graphic EQs:
dbx Type V™ Noise Reduction: This button engages (when lit) the dbx Type V™ Noise
Reduction circuit within the EQ. Typically, graphic equalizers raise the noise floor within the
signal path, and dbx’s proprietary Type V™ noise reduction will reduce the apparent noise floor
through its simultaneous encode/decode process (shown below). The button lights when the
dbx Type V™ Noise Reduction circuit is activated.
Frequency Band Slider Controls: Each one of these slider potentiometers will boost or cut at
its noted frequency by ±6dB or ±15dB, depending upon the position of the BOOST/CUT
RANGE switch. When all the sliders are in the center detented position the output of the equalizer is flat. The frequency band centers of the iEQ-31 are marked at 1/3rd of an octave intervals on ISO standard spacings, while the frequency band centers of the iEQ-15 are marked at
2/3rds of an octave intervals on ISO standard spacings.
Low Cut Enable: The LOW-CUT button inserts (when lit) or removes the 18dB/octave 40Hz
Bessel low-cut filter from the signal path. When the LOW-CUT switch is pushed in, the LOWCUT filter is IN the audio path.

The iEQ Series Equalizers have balanced inputs and outputs that can be used with any balanced
or unbalanced line-level device.
To connect the equalizer to your sound system refer to the following steps:
• Turn off all equipment before making connections.
• Mount equalizer in a standard-width rack.
Install the EQs in a rack with the rack screws provided. It can be mounted above or below
anything that does not generate excessive heat. Ambient temperatures should not exceed
113° F (45°C) when equipment is in use. Although the unit’s chassis is shielded against radio
frequency and electromagnetic interference, extremely high fields of RF and EMI should be
avoided.
• Make audio connections via XLR, 1/4” TRS jacks or Euroblock connectors according to applica-
tion needs. All three types of connectors for the inputs and outputs can be used for balanced
or unbalanced connections. The use of more than one connector at a time for the inputs could
unbalance balanced lines, cause phase cancellation, short a conductor to ground, or cause damage to other equipment connected to the equalizer. More than one output may be used simultaneously as long as the combined parallel load is greater than 600Ω.
• Select the operating range with the boost/Cut range selection switch
Note: Be sure to reduce audio levels at the power amplifiers when changing the setting of this
switch as it may generate an audible transient.
• Apply power to the equalizer. Connect the AC power cord to the AC power receptacle on the
back of the equalizer. Route the AC power cord to a convenient power outlet away from audio
lines. The unit may be turned on and off from the rear panel power switch or a master equipment power switch. Since the iEQ Series Equalizers consume a relatively small amount of power,
the units may be left on continuously.
