Using your system
For realistic home theater sound
CAUTION: The Acoustimass
®
15 Series II and Acoustimass 16 speaker systems incorporate
an automatic protection circuit, which guards against most kinds of damage from electrical
stress or overload. This circuit activates at high volume levels to reduce output, causing a
slight decrease in volume. This is normal operation and indicates that power input may be
exceeding safe levels. Sustained listening at these levels is not recommended.
Adjusting the LFE level
The LFE (low-frequency effects) level control on your powered Acoustimass module
increases or decreases the relative level of low-frequency effects on movie sound tracks. Use
it to regulate the presence of these underlying deep bass sounds. Use the “test tones” feature
in your digital surround sound receiver to match the volume levels for each of the cube
speakers. Then use the LFE control on the Acoustimass module to match the volume of the
LFE channel to the cube speaker channels.
Adjusting the bass/room compensation level
This feature will allow you to fine-tune your system after you have placed the Acoustimass
module in your selected location. If the room sounds “thin” or lacks bass, turn the BASS con-
trol in a clockwise direction to increase the bass level of the module. If the room sounds
“boomy” or has too much bass, turn the knob in a counter-clockwise rotation to reduce the
bass level of the module. The factory or detent setting is appropriate for a majority of listening
situations.
Setting your digital surround sound receiver
Your Acoustimass 16 or Acoustimass 15 Series II speakers are fully compatible with the
output from digital surround receivers. Integrated Signal Processing assures full bass
reproduction for all channels regardless of receiver settings. However, the following table
suggests a set of recommended receiver settings. The cube speaker arrays should be set to
LARGE in the receiver’s digital display menu. The LFE, or subwoofer, is set to ON. If applica-
ble, the crossover value should be set to the lowest number possible, typically 80 Hz.

* Applies to Acoustimass 16 systems or upgraded Acoustimass 15 Series II systems. For upgrade
information, see “Upgrading your Acoustimass 15 Series II speaker system” on page 12.
