SYSTEM RESPONSE SCREEN
From the
Introductory
screen you can get to the
System Response
screen which is used to display the frequency response graph for the
subwoofer’s output. See Figure 3. See the Remote Control Button Sequence Commands table on page 25 for the button sequence.
The
System Response
screen has the following information and features on it:
• A system response graph that shows the subwoofer’s low frequency output from 15 to 200 Hz.
• A moving screen pixel marks on the frequency response curve the current frequency of the sweep tone that is playing.
• 8 parametric filters each of which can be used at its current frequency or adjusted to a frequency and Q you desire between 15
and 200 Hz when in Manual-EQ mode.
The filter level range is -13db to +6dB although the screen is only marked from -12dB to +6dB.
