Using Your System
Getting the most from your home theater speakers
With system connections completed and the module plugged in, your Acoustimass
®
system is now ready for use.
Familiarize yourself with the controls and built-in protections that adjust the audio of this system. They offer options to suit your particular
style of use and preferences.
CAUTION: This system provides an automatic protection circuit to help guard against damage from electrical stresses and overload of
the system. At high volume levels, the circuit activates to reduce output, which slightly decreases the volume. If you notice
this decrease, be aware that your system is functioning as designed. This volume reduction also indicates that power input
to the system may exceed safe levels. Sustained listening at these levels is not recommended.
Adjusting the bass/room compensation
After placing the Acoustimass module where you want it, you can fine-tune it for that location. Make this adjustment only as necessary.
For example:
• If the system performance lacks bass, turn the BASS control (shown above) clockwise to increase the low-frequency output of the
module.
• If the audio overemphasizes bass, turn the knob counter-clockwise to reduce the low-frequency output of the module.
The setting made at the factory is meant for use in the most common room arrangements.
Adjusting the LFE level
The LFE level control (shown above) is for use only with receivers that provide an LFE/SUBWOOFER channel.
By turning the knob, you can adjust the relative level of the low-frequency effects from movie soundtracks. Use it to match the volume
level of the LFE channel with volume levels of your other speaker channels.
You can check all levels by using the “test tones” feature on your digital surround sound receiver. For details on using this feature, refer
to the owner’s guide provided with your surround receiver.
