both over-current and thermal protection. A combination of

electronic components are used, first to absorb excess power and

then ultimately to switch the speaker components to a lower

power level. If you put too much power into the speaker system,

you'll notice what appears to be lamps flashing on and off inside

the speaker (you'll be able to see this through the bass ports). If

you continue to apply too much power, you'll hear the sound

level reduced by a noticeable amount. You should then reduce

the signal level to the speaker system. Within a short time, the

circuitry will automatically reset and will return to normal

operating capability. Unlike many other protection circuits,

there are no fuses or other user-serviceable devices in the

crossover circuitry, which makes your Community loudspeaker

system one of the least-likely items to let you down.

Using CSX40, CSX50 and CSX60 subwoofer systems

While all Community full-range speaker systems have remark-

able bass output, there are situations where you may need more

as provided by the CSX40, CSX50 and CSX60 subwoofers.

A very special feature of these products is that they have built-

in crossovers with high-pass outputs. This means that you may

use one channel of your power amplifier to power both a

subwoofer and a full-range speaker, while maintaining a reason-

able load on your amplifier. The amplifier only sees the

subwoofer/crossover load which is 4 ohms for CSX series

subwoofers. Without the built-in crossover, the combined

impedance of full-range and subwoofer speakers in parallel

would be much lower. Many amplifiers are capable of powering

very low-impedance loads, but some cannot. This feature neatly

addresses that problem. Also, the high-pass crossover output

removes the very low bass frequencies from the signal going to

the full-range speaker. This prevents distortion (and possible

damage) from excessive low-frequency energy getting into the

full-range speaker.

When connecting a Community subwoofer to a full range system

using the subwoofer's "Output for Fullrange System", the
