CONNECTION & CONTROLS
CONTROL FACILITIES
Take the time to read through the following descriptions
and become familiar with them before you begin to fine
tune your new system.
Auto-On/Off
Eliminates the need for a manually operated power switch.
Turns the subwoofer on whenever there is an input signal.
If no input signal is sensed after a period of time the
subwoofer will switch off automatically.
Trigger-On/Off
Allows the subwoofer's power on/off to be controlled
by components that have trigger outputs (Preamp/
Processor or A/V Receiver, etc.).
Subwoofer Level
Balances the subwoofer's output level with the other
speakers in your system. Once set, to make on-the-fly
changes for particular program material or personal
taste, use your Processor or A/V Receiver's subwoofer
level control.
Subwoofer Cut-Off and Bypass Option
Controls the subwoofer's upper-frequency cut-off.
This can be set to match the low-frequency roll-off
(continued)
characteristics of your system's speakers. For example: If
your speakers play to approximately 80 Hz, you can set the
subwoofer cut-off frequency to approximately 80 Hz.
Bypass option allows you to bypass the subwoofer's
built-in cut-off control to let your preamp/processor's
or receiver's internal bass management system provide
the crossover function.
Phase Alignment
Depending on where the subwoofer is placed in your
room, there may be bass frequency cancellation. This
can occur because your subwoofer and front speakers
are out-of-phase—they work against each other through
their frequency overlap region. Bass is then reduced and
may even sound disjointed. This control accurately
synchronizes your subwoofer and front speakers through
their bass frequency overlap region.
THE USB PORT / ARC INTERFACE
Allows for:
• Connection of Anthem Room Correction (ARC) Kit
(for more information see the preceding section);
• Possible future upgrades to the software installed
in your subwoofer.
