The Bypass control enables or disables the parametric EQ, loudness contours, and high pass
filters.
The Monitor Output sections each contain Protection Limiters, a useful feature when
performing speaker calibrations, which are often performed at higher than normal volume
levels and can involve radical amounts of parametric equalization in the pursuit of a flat
frequency response. The Master Gain control adjusts the output level of each Monitor
Output section relative to the Protection Limiter. If you find yourself hitting the limiter at
normal volume levels during or after calibration, reduce the Master Gain control. You may
also find that in the course of calibration you have made significant cuts to achieve a flat
output, and need to use this control to raise the output level so that the calibrated and un-­‐
calibrated outputs match volume-­‐wise when you compare them by using the Bypass control.
The Left Level and Right Level controls allow you to adjust the output gain of each channel
individually and act as a sort of “balance” control in situations where the left and right
speakers are not equally spaced from the monitor point.
The Solo Left and Solo Right controls allow you to monitor only the left or only the right
channel.
The Left High Pass Filter and Right High Pass Filter controls allow you to set the high pass
filter cutoff point anywhere between 0 and 880Hz. When calibrating smaller bass-­‐shy
speakers, there will come a point where you can no longer compensate for such a deficiency
by EQ-­‐ing, and it is more practical to simply not try and pass those frequencies at all. That
point will be clear on the RTA and is explained in more detail in the Speaker Calibration
section.
The Pink Noise Left and Pink Noise Right controls turn the pink noise generator in each
channel on or off.
The Main2 Menu
The Main2 Menu contains the controls to set the output level of each Monitor Output, adjust the
master gain level, determine whether the left and right channels are adjusted together as a
“common” pair for both the parametric EQ and the Delay functions, invert the polarity of each
channel, set the overall delay time and individual channel delay, and adjust the Bass Clipper and
Limiter Thresholds for each channel.
The Volume and Master Gain controls are duplicates of those found in the Main1 menu, but
are found here as well for convenience.
