  • Page 6 The X2 can be used to crossover a mono or stereo subwoofer to a stereo satellite system as long as the desired crossover frequency falls into the 50 to 200Hz range. If using a mono subwoofer, three channels of amplification will be needed. If using a stereo subwoofer system, four channels of ampli- fication will be needed.

  • Page 9 High Pass Filter Switch (Rear Panel) The High Pass Filter determines the range of frequencies that the main speakers ("satellites") will reproduce. For example, a high pass setting of 80Hz means that the main speakers receive a signal containing only frequencies above 80Hz. The 3-positon High Pass Filter is selectable between 50Hz, 80Hz, and 110Hz to accommodate a vari- ety of speaker sizes.
  • Page 10 10dB. Normally, the factory default "0" position will give you a wide range of volume adjustment. However, if the sensitivity of your satellite speakers is greater than 93dB, your range of volume adjustment on the X2 may be limited. In this case, set the Gain Switch to 10dB.
  • Page 11 Located on the right hand side of the front panel are two LEDs. They are used to indicate the func- tional status of the X2 Crossover. P - Power LED (green) - indicates the X2 is on and in a ready condition. S - Standby LED (amber) - indicates the X2 crossover is in "standby" mode.
