Operating & Controlling Your SUB-80X

*Secure all connection before powering up/plugging in the AC cord into the subwoofer.

*Connect the input signal to either the RCA lin in (A) or the High Level input terminal (F); these two input devices can not be used simultaneously, choose the one that best matches the output of your existing audio system.

*If needed, connect the RCA line out (B) to another amplifier to drive satellite speakers (front or rear). The RCA line out has high pass filtered signal at about 70Hz (5dB/Octave cut off).

*The High Level input (I) for satellite speakers is fitted with a High Pass filter (70Hz). It is only powered when the main or front speaker signals are driven into the High Level input (J). These terminals are marked with red and black to indicate the (+) & (-) respectively.

*Adjust the subwoofer low pass filter cut off to near 100Hz at first, slowly bring down the crossing point until you eliminate any vocals from emanating from the subwoofer. An ideal crossing pint range from 55 to 70Hz

*In case the SUB-80X becomes out of phase with the satellite speaker, flip the phase switch to correct the problem (maximum bass is only achieved when the sub is in phase with rest of your speakers).

Cautions:

*Do not place the subwoofer in an environment exposed to dust, excessive moisture or heat. Direct exposure to sun light will over time deteriorate the enclosure finish and may cause the amplifier to overheat.

*To prevent electrical shock, never open the subwoofer cabinet before disconnecting the power cord from the amplifier's main socket.

*In the event of a blown fuse, replace it with a 1 ampere fuse only. Over fusing voids the warranty and will destroy the amplifier.
