B) For use with A/V preamps and receivers that have 5.1 channel line level

outputs.

If your preamplifier or receiver has a single "subwoofer" output or "LFE" output,

connect a shielded cable from the preamplifier output to either one of the

subwoofer line level inputs. Refer to Figure E.

UNPACKAGING/PRE-INSTALLATION INSTRUCTIONS

Unpack your new subwoofer carefully, keeping the carton and packing material for

future use. Check the condition of your unit, reporting any damage which may have

occurred in transit to your dealer or shipping company.

The following list of terms with their definitions is offered as a help in understanding the

set-up and operation of your subwoofer.

Crossover (xover) - an electrical filter with lo-pass or hi-pass characteristics that

divides the frequency range into bands of low, middle, or high frequencies to match

the capabilities of specialized loudspeakers like subwoofers that are only effective at

reproducing limited frequency ranges. The crossover frequency is the frequency where

the filter begins to attenuate or reduce the level of the signal.

Full range - refers to signals which cover the entire audio frequency span from 20 Hz

to 20 kHz.

Hi-pass - a type of filter circuit that allows high frequencies to pass, while reducing the

level of low frequencies with the transition from high to low occurring at the crossover

frequency. The rate of reduction of the signal is called the attenuation rate or slope

and is measured in decibels (dB) over a change in frequency of one octave which is a

doubling or halving of frequency.

Impedance - the resistance to the flow of current in an alternating current circuit (such

as with music). Line level circuits are typically a high impedance of several thousand

ohms, while speaker level circuits are usually a low impedance of a few ohms.

Line level - the type of signal produced at the outputs of preamplifiers, tape decks,

CD players, etc., with a typical value of a volt or less in a high impedance circuit.

Sometimes called low level signals, they are routed using shielded cables which are

usually terminated with RCA phono connectors.

Lo-pass - a type of filter circuit that allows low frequencies to pass, while reducing the

level of high frequencies with the transition from low to high occurring at the crossover

frequency. The rate of reduction is called the attenuation rate or slope and is measured

in decibels (dB) over a change in frequency of one octave which is a doubling or

halving of frequency.

Speaker level - the type of signal produced at the outputs of power amplifiers that may

be many volts in a low impedance circuit. Sometimes called high level signals, they

are routed using two conductor unshielded wire of 18 gauge or larger. Connections are

usually made with stripped ends of wire gripped in spring loaded terminals.
