Earthquake Sound SUB100 User Manual

Low level -RCA-  audio input connection:

This is the best way to drive an audio signal into the  subwoofer. Today, 

all   signal processors(5.1/6.1 and more advanced ones) come equipped with 
built-in  pre-a mplifier outputs (RCA) that include a subwoofer output. 
Generally, the SUB/OUT is in mono format. As shown in the photos across, 
connect the SUB/OUT from the processor to the subwoofer using a "Y" 
connector to feed both RCA inputs of the subwoofer. We strongly recommend 
that you use the best available RCA connectors and cables. High quality cables 
are normally triple shielded,  and the connectors are gold plated with forceful 
grasping (refer to Earthquake line of accessories- SI superior Interconnect - at 
www.earthquakesound.com). 

High level audio input connection:

This is the least desired  way to drive an audio signal into the   

subwoofer. Older stereo systems are not equipped with pre-amplifier 
audio outputs, normally they come with stereo speaker outputs (left & 
right). Using "banana" plugs, connect the speaker outputs to the 
corresponding Subwoofer high level inputs (marked "FROM 
RECEIVER). In this configuration, the front stereo speakers (towers) 
can be powered up by connecting them to the subwoofer  speaker 
outputs. The amount of power (watts)  driven   into the stereo speakers 
(towers) is identical to the amount of power (watts) fed into the 
subwoofer from the stereo system (ratio 1:1).
