These PHANTOM models feature variable low pass and subsonic filters and a variable input gain control. These amplifiers also incorporate a phase selector switch to help compensate for time delays in subwoofer applications. For further flexibility in the use of a subwoofer, a variable 0-+18dB Bass Boost control has been included.You can control the subwoofer level with the remote level control module. understands that amplifiers are placed in many different kinds of installations, so we have also included an input sensitivity control to help you integrate the amp into your system regardless of the nature of your input source. A special feature on this Class D amp is DataLink circuitry, which allows you to "strap" together (for example) two PH5000D's for an astounding total maximum output power of 10,000 watts.
