CLS-10 / 12 Subwoofer Controls and Connections
the fuse blows again, disconnect the power cord from the AC wall supply and contact your local Gallo
Acoustics dealer, or contact us directly.
Dual Subwoofer Connections
Connection Using High-Level (Speaker-Wire) Inputs: Instead of running Left and Right Channel speaker
cables from your receiver or amplifier to both subwoofers, you can run the Left Channel to one sub-
woofer and the Right Channel to the other. Take care to make Positive to Positive (Red / +) and
Negative to Negative (Black / -) terminal connections.
Note:
When the High-Level Inputs are used, the speaker-level output terminals of the subwoofer have
available a 100Hz high-passed signal (deep bass removed) that can be used to drive the satellite
speakers. This gives you a limited form of Bass Management and can be used for the Main L/R, center,
or surround speakers, depending upon how many subwoofers are employed.
Connection Using Low-Level (RCA-Cable) Inputs:
From your receiver or preamp, attach an RCA-type
“Y” connector to the Sub/LFE out (unless your receiver/processor already has two Sub/LFE outputs).
Connect an RCA-to-RCA interconnect cable from one leg of the Y connector or one of the two
receiver/processor Sub/LFE outputs to each subwoofer’s Low-Level/LFE input. In this setup, the satellite
speaker connections are made between your receiver or amplifier in a traditional manner. If you’re
connecting multiple Gallo subwoofers using the Line Level RCA connections you can “daisy chain”
from one to the next using the RCA In and RCA Out connectors on each sub.
