A WORD OF ADVICE
The low-frequency Crossover and Volume controls may be set anywhere within their rotation
However, it will be a most unusual circumstance if you have to set the Volume control completel
clockwise. This may indicate an unbalanced condition in your system (too much bass), that th
system is in an especially large room, or that speaker placement may be incorrect. Try sever
other locations before concluding that the Volume control must be set at maximum.
OVERDRIVE PROTECTION
Automatic limiting circuitry helps prevent overdriving a connected subwoofer by softly clippin
the input signal if it exceeds a predetermined threshold. Depending on the level, you may o
may not hear slight distortion on musical peaks. This protection is completely automatic, wit
no user adjustments. However, if you do hear distortion continuously while playing musi
the input signal level (feeding the HPS) may be too high and should be lowered. If this doesn
solve the problem, check the connections and that the other components in the audio chain ar
operating properly.
A WORD ABOUT TONE CONTROLS
The tone controls on your electronic components (preamplifier, receiver, etc.) should be use
with the utmost discretion. Excessive boost can create severe power demands on your powe
amplifier. Maximum bass boost can create a demand for literally hundreds of watts in the bas
region, whereas in the “flat” position, or with the tone controls switched out of the system, you
average listening level may be impressively and realistically loud at fewer than 10 watts. Th
remaining power capacity required is on reserve for power peaks on sharp transients an
powerful crescendos.
