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. 
You may want to familiarize yourself with the controls and built-in protections that adjust !
the audio of this system (Figure 9). 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.

Audio adjustment knobs
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 is “thin” or lacks bass, turn the BASS control (shown above) 
clockwise to increase the low-frequency output of the module. 
• If the audio is “boomy” or 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/SUB-
WOOFER 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.

Setting your digital surround sound receiver 
Speakers in your Acoustimass® 6 Series III or Acoustimass 10 Series IV system are fully !
compatible with the audio output of digital surround receivers. The system’s integrated signal 
processing supports full low-frequency reproduction from all channels. 
To gain complete advantage of these system capabilities, you may want to adjust some!
settings on your receiver. To make changes, use the digital display menu on the receiver and 
refer to the list of recommended settings, below.
Speaker Receiver setting
• Left and right LARGE
• Center LARGE
• Left and right surround LARGE
• LFE/Subwoofer ON
Note:
If your receiver provides it, the LFE or Subwoofer option setting should be ON and the 
crossover value at the lowest number possible, which is typically 80 Hz.
Receiving a digital audio signal
For the digital audio signal from your DVD player to reach your surround receiver, you need a 
digital audio connection between the DVD player and receiver (Figure 10).
1. Use either the Optical or Coaxial input (not both) on the receiver to connect to the digital 
output from the DVD. 
2. Be sure to select the digital output in the setup menu of your DVD player. 
For additional setup and operating information, please refer to the owner’s guide that came 
with your surround receiver.

Setting your analog surround sound receiver 
For analog (non-digital) surround sound applications, we recommend that you set the !
surround sound center mode of your receiver to Wide. For instructions on how to change this 
setting, refer to the owner’s guide provided with your surround receiver.
