Setting your non-digital receiver
After making the connections, you may try additional surround sound modes that your
receiver may have. These modes may have different names depending on the manufacturer,
e.g. ACTION, MOVIE, THEATER. Select the settings for music, movies, or both that sound
best in your listening environment. See your receiver/amplifier owner's guide for additional
information on selecting settings.

CAUTION: 701
speakers 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. You may also notice light com-
ing from inside the speaker cabinet. This is normal operation and indicates that power input
may be exceeding safe levels. Sustained listening at these levels is not recommended.
Setting your digital receiver
Your speakers are fully compatible with the output from most receivers containing digital
technology. The table below suggests the recommended settings. Because they are full-
range speakers, select LARGE on the digital screen menu. Turn the subwoofer and the LFE
(low frequency effects) on. The preferred crossover setting should be 150 Hz.

LFE
Your left main speaker has two control knobs – one for bass control and one for LFE control.
Follow the instructions below for using these controls.
Bass control
The bass control, located on the outside of the left main speaker, can help you customize the
speakers to your listening room. Turning the control to the right will add bass to the sound in
rooms that might be characterized as too shrill. Turning the control to the left will "brighten"
the sound of the listening room. As with LFE control, you may find the factory setting to be
completely appropriate for your listening room.
LFE level control
The LFE control, located on the outside of your left main speaker, 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. You may find it unnecessary to adjust this control. The
factory, or detent, setting is appropriate for a majority of listening situations.
