Emotiva XMC-1 User Manual page 60

The behavior of the controls used to adjust the parameters for the parametric equalizers in the
XMC-1 has been meticulously optimized to make the process of making so many adjustments as
simple and straightforward as possible. As a result, certain displayed fields will be synchronized
even though they may be independently configurable. Others may display the same information
in multiple locations to make the process of adjusting them easier.
It may take you a little while to get used to the way the controls work but, once you practice
a little bit, we're sure you'll find them efficient, convenient, and, most important of all, not
confusing.
• You may, of course, adjust all of the filter bands for one speaker, then move on to the next
speaker. However, if you prefer to adjust a specific band for all speakers, then move on
to adjust the next band for all speakers, the XMC-1 facilitates this by remaining set to the
particular EQ band number you're working on when you switch between speakers. For
example, if you're adjusting Filter 3 for your Front Right speaker, and you then switch to
the Front Left speaker, you will be taken directly to the settings for Filter 3 for the Front Left
speaker; this way you can very easily adjust each Filter band sequentially for all your speakers.
• Test Tone Level and Test Tone Frequency settings are global; even though the controls for the
Test Tone Generator appear on several different menu screens, there is only a single Test Tone
Generator which you are accessing from different places. Therefore, as you move from place to
place in the menu system where the Test Tone Generator is used, the Test Tone Generator will
remain set at the last Level and Frequency you select until you change it. When you exit the
area of the menu where the Test Tone Generator is used, it will automatically switch Off.
Filter Level
For each filter, you can set the level from -64 dB to +6 dB in 0.5 dB increments.
Note: While it is not uncommon to have some overlap between EQ filters, or to have a narrow
notch that falls inside a wider filter band where gain is applied, you should be careful about
applying positive gain on overlapping filters; and avoid deliberately stacking multiple filters
to create gain in excess of +6 dB. Although unlikely, it is possible, by applying excessive gain to
overlapping bands,to cause the XMC-1 to clip.
Filter Width
For each filter, you can set the band width to cover anywhere from a faction of an octave to
several octaves. As you change the Filter Width setting, the width you set will be displayed as a
traditional "Q" value, and as an actual range between the edges of the band. The edges of the
band are defined as the points where the filter is at 50% of its maximum effect - expressed in dB.
(For example, if a band is set to provide -20 dB of gain, then edges of that band are defined as the
-10 dB points.)
Note: you can adjust the width of each filter by changing the value in either the Q field or the
field that shows the width of the band in hz. however, while you are changing the value, only
the number in the field you are using will change dynamically; the value in the other field will
synchronize as soon as you exit the active field.
