iEQ
iEQ31 - dual channel 31 band graphic equalizer
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 but-
ton 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 select-
ed.
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
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:
