Setting Control
The Setting Control switch adjusts how level (volume) and settings
of the subwoofer are controlled.
• App: When this switch is set to "App" all of the subwoofer's
control functions (except for Power Mode) are controlled via the
subwoofer control app. Please note: To fully release control of
the sub to the local controls, you must fully exit any active ses-
sions of the Subwoofer Control App.
• Local: When this switch is set to "Local" the sub's Level (volume)
control knob is active and the rest of the sub's settings are set
to default settings. The local setting is intended for applications
where you connect the subwoofer to a receiver/processor and
let the receiver/processor handle most of the settings.
Subwoofer Default Settings:
Phase: 0°
Polarity: Normal
Low-pass: 120Hz 4th order
20–30Hz Level: 0dB
ARC: Off
If the subwoofer is setup with the app and the Setting Control
changes to Local, all of the subwoofer's settings change to
default. However, when the switch is changed back to App,
the previous app settings are re-engaged.
Level
The level knob is only active when Setting Control is set to "Local".
When Setting Control is set to "App" the level is controlled via the
subwoofer control app. Setting the level too high will cause the
bass to seem bloated and is the single most common cause of
bad sounding subwoofers. A rule of thumb is that the subwoofer
should not draw attention to itself, but should simply make the sys-
tems low end seem more extended and accurate.
USB Input
This input is used to apply firmware updates and to run ARC from
a PC. ARC is discussed in detail later in this manual. Even when a
subwoofer is perfectly positioned, the room can have a dramatic
impact on bass performance. Room dimensions, dead spots, arch-
ways, furniture, and countless other factors can turn a room into
an additional instrument playing alongside musicians or movie
scores with unwanted contributions of coloration and resonance.
Although the controls on your subwoofer allow you to fine tune
and optimize bass performance in your room, ARC™ allows you
to also correct for the effects of your rooms boundaries.
