This feature may or may not be useful to you, and perhaps you should just leave
this setup option until you find you actually need it.
Not all subwoofers are created equal. Many Subwoofers will take all the power
which might be expected to be included in a movie or on a Music CD. Other
Subwoofers are not as capable.
Part of the reason we suggest you delay the setup of the limiter is the danger that
you might damage the speaker during setup. You are required to turn up the
volume of the noise generator until the woofer amplifier clips or the cone bottoms
out, and then to turn up the limiter value until the clipping stops.
Some More Notes on Subwoofer Limit
We suggest that unless you are particularly concerned about the level your
subwoofer will be required to output that you leave the limiter in its off
mode. Off is the +00 dB level.
If you do decide to utilize the limiter, follow the instructions below. Do not allow
the subwoofer to play at clipping level for any length of time. Most of all, please be
careful.
To begin the Subwoofer Limit procedure you have to ensure the noise generator will operate. Press “MENU”, then
press the “>” key twice to display “Main menu – System setup.” Select this option by pressing “ENTER”, then press the
>” key four times to navigate to “System setup – Feature setup.” Select this option by pressing “ENTER”. “Feature
setup – Noise gen.: auto” will be displayed. Be sure either “auto” or “man” is displayed, or the noise generator will not
operate when you attempt to set the subwoofer Limiter. Whether you select “auto” or “man,” only the woofer will play
when in Subwoofer limit mode.
Press "MENU" again to go back to “System setup – Feature setup,” then press the “<” key to go to “System setup –
Subwoofer limit.” Press “ENTER” to select the option, and you will see “Subwoofer limit – Level: +00 dB.” and the
woofer will begin playing at whatever level the main volume is set to.
By pressing the “VOLUME /\ (Volume Up) key on the remote you can increase the level of sound from the woofer
(only the woofer will be playing). Increase the level until the woofer or its associated amplifier begins to clip. The
amplifier may have a clipping indicator which will come on and stay on. If it is a powered subwoofer it may have a
clipping indicator on a control panel. The woofer cone may bang up against the end of its travel (which will destroy it
very quickly). IF THE WOOFER CONE BOTTOMS OUT, IMMEDIATELY
REDUCE THE MAIN VOLUME TO STOP
THE DESTRUCTIVE OPERATION.
The woofer will be VERY loud. The sustained clipping level may break it.
Immediately begin repeatedly pressing the “\/ key (below the “ENTER” key), to begin increasing the limiter level, until
the clipping stops. Increase the main volume slightly by pressing the “VOLUME /\” key to see whether the clipping
occurs again. If it does, press the “\/ key below the “ENTER” key again to stop the clipping. Press the "MENU" key to
turn off the set limiter mode and turn the main volume down again to a reasonable level. You should be done; it should
now be possible to play the Subwoofer in your system right up to but not over its clipping level.
Return to full operation mode by pressing "MENU" three times.
