Earthquake Sound Down-Firing SUB 120 - Manual (Page 3)

Connecting Your Subwoofer
-3-
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).
