1.	Volume	3.	Phase Control

This control lets you match the output level of the subwoofer to the level

of your satellite/main speakers. The subwoofer output will increase as this control is rotated clockwise. When you have just installed your system, turn this down Þrst before turning on your subwoofer. This will prevent any loud surprises.

2. Crossover Frequency

This controls the high frequency cutoff point. With the control set to the 100 Hz mark, the subwoofer will reproduce frequencies up to 100 Hz. If the control is set fully clockwise, the crossover is bypassed and the subwoofer will re- produce a wide frequency range. With the control fully counter-clockwise the subwoofer reproduces a narrow range, up to 30 Hz.

Rotate the control until the bass sounds natural. If the mid-bass sounds natural but you want more low bass, turn this control down a little, then turn the Volume control up by about the same amount. This increases the low-bass output while leaving the mid-bass output the same.

This control changes the relative phase of the subwoofer with respect to your other speakers. Use this control to help blend the subwoofer with the rest of your system. This is accomplished by adjusting the control in small incre- ments as you listen for the most bass at your listening position. As a Þnal trim, readjust the Crossover Frequency and Volume controls after the Phase has been set.

4. Trigger Inputs

These two inputs can be used to auto- matically turn on the subwoofer. To do this, connect 12 VDC to either of these terminals. Some Home Theater pre- ampliÞers, such as the SunÞre Theater Grand II and III, have matching 12 VDC Trigger outputs. When they are turned on, the subwoofer will turn on.

5. Outputs

Line level high-pass output signals are available at these jacks. These outputs are active whenever a signal is hooked up to the line level inputs of the subwoofer. This crossover is a
