OPTIMIZER
In mono mode the signal is
routed from output 2 to the
input of 3, this places all four
sections in series. You can
tap out after 2 as well as 4,
you can use this feature for
blends on the mixer.
Each of the four OPTIMIZER
filters is equipped with an
individual bypass switch.
The Master-EQ switch hard
relay bypasses all filters with
balanced XLR connectors.
The Peak LEDs flash at
approximately 3dB below the
actual clipping level.

All four channels of the Optimizer are identical. The cen-
trally mounted Dual switch selects between stereo 2-band
and mono 4-band operation. In Dual mode, a green status
LED illuminates. For use with stereo signals such as complete
mixes or sub-mixes, the Optimizer should be switched to
Dual mode and both sets of channel controls set to the same
position. Equalizers 1 and 2 work as a pair as do 3 and 4.
However, in Mono mode, (Dual button out), the signal is
automatically routed from the output of equalizer 2 to the
input of equalizer 3, placing all four equalizer sections in
series. Because the signal routing is controlled by the Dual
switch and not by normalising connectors, no additional
measures need to be taken when using the Optimizer with a
patchbay system.
In Mono mode, both sets of outputs continue to function
normally, allowing one signal to be tapped off after passing
through filters 1 and 2 and another to be taken after passing
through all four filter sections.
The Active switch is used to switch the individual equali-
zer section in and out of the signal path. The Active switch
operates as an electronic bypass. Take care when switching
the Active function in and out, when listening at high moni-
tor levels. Depending on the EQ settings a click may occur at
the moment of switching, so dim or mute the monitors if
necessary.
The Master EQ switch is a hard relay bypass which links
the input socket directly with the output socket to bypass all
filters by pressing just one button. Note: this only applies
when using the balanced XLR inputs and outputs in stereo
operation. When working with unbalanced signals, this
switch has no effect. The switch has an integral red lamp
which illuminates when Master-EQ is active.
To increase operation reliability especially in Live or On-
Air situations, the Optimizer monitors the power supply´s
primary and secondary voltages and switches automatically
to hard bypass once certain tolerances have been exceeded.
A peak LED is fitted to each EQ section, which flashes at
approximately 3dB below the level at which clipping occurs.
If the Peak LED constantly flashes, the input to the equalizer
