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.
