Earthquake Sound SUB-80X Dear Valued Customer, Key Connection and Controls, Digital, P O W E R

Dear Valued Customer,

Congratulation on your choice of the SUB-80X self powered subwoofer system, one of Earthquake's newest designs in bass reproduction units.

With an integral high-power amplifier - 150 Watts, the SUB-80X subwoofer combines tight bass extension with high output levels. Acoustically, it is designed to match typical satellite speaker systems to enhance the over all sound quality and performance of your system.

Key Connection and Controls:

A)LINE IN RCA - Input jacks, accept up to 1.4 volts of audio input signal (mono and stereo).

B)LIN OUT RCA - High pass filtered RCA output jacks with left and right line output signals. The line out RCA's are not functional when the line in signal (going into the subwoofer) is derived from a sub-filtered output of an external processor.

C)XOVER FILTER - The 12dB/Octave variable crossover filter is designed to control the subwoofer cut off frequency (range from: 40Hz to 130Hz).

D)VOLUME CONTROL - Manual adjustment of the sound level of the subwoofer. Always start at MIN position and slowly increase the volume to reach the desired subwoofer level.

E)PHASE SHIFT - 0 to 180 degrees subwoofer phase shift switch.

F)POWER SWITCH - For operating the amplifier automatic or manual power on. In automatic mode, the SUB-80X will turn OFF in 15 minutes if no audio signal is detected.
