8) You can watch the subwoofer smooth its frequency response by adjusting the parametric EQ filters on the System Response screen.
Self-EQ doesn’t change the Setup preset parameters (volume, crossover, etc.) and uses the crossover set to 160 Hz.
9) When Self-EQ finishes, the sweep tones stop, the front status message shows End for 10 seconds, the subwoofer reboots by turning
itself off and back on. The subwoofer display shows the preset number and then volume level. During this process the new filter
settings are saved into the subwoofer’s memory.
Running Auto-EQ PLUS Optimization – Stepping Up in Power
The next level up in the Digital Drive PLUS EQ optimization methods is Auto-EQ PLUS optimization. To perform Auto-EQ PLUS optimization:
1) Set up the microphone as in the Self-EQ instructions above.
2) Connect your subwoofer to your TV video input as described above in the Make Video Connection between TV
and Subwoofer section.
3) Make sure the subwoofer and your audio system are both on.
4) Place the Digital Drive PLUS Sweep Tone CD into your disc player and press play.
5) Once the sweep tone starts to play, adjust the receiver or processor output level to about the level of a normal-loudness
conversation at the mic.
6) Press and hold EQ on the remote until Auto-EQ PLUS starts; you will see on the System Response screen the AUTO option in the
EQ MODE area. See Figure 16.
The Auto-EQ PLUS proceeds until one of the following occurs:
• Auto-EQ PLUS finishes successfully, saving the settings.
• You decide to quit, and press RESET on the remote. You exit back to the Introductory screen, you don’t see the Auto-EQ PLUS
frequency response curve any more.
• You move the cursor off the AUTO field (in which case the field automatically reverts to Manual-EQ).
• The frequency response level is too high (peaks over 87 dB) or too low (average level below 70 dB).
• The Sweep Tone CD stops playing.
7) The Digital Drive PLUS subwoofer not only adjusts the Setup preset EQ filter levels as you watch, but it also adjusts the subwoofer level,
crossover, slope, and phase during the Auto-EQ PLUS optimization process.
8) You can also watch the status messages during the process in the upper left hand corner of the TV screen.
