TV SCREEN USER INTERFACE FOR OPTIMIZATION

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-EQPLUSOptimization – Stepping Up in Power

The next level up in the Digital DrivePLUS EQ optimization methods is Auto-EQPLUSoptimization. To perform Auto-EQPLUSoptimization:

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 DrivePLUS 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-EQPLUSstarts; you will see on the System Response screen the AUTO option in the EQ MODE area. See Figure 16.

The Auto-EQPLUSproceeds until one of the following occurs:

Auto-EQPLUSfinishes 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-EQPLUSfrequency 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 DrivePLUS 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-EQPLUSoptimization process.

8)You can also watch the status messages during the process in the upper left hand corner of the TV screen.
