ENGLISH
position and use the BYPASS switch often to compare between original and
processed sound.
Important: Note that the high band processor should be used with care to avoid
possible tweeter damage. Improper and excessive use of high band processor
can cause overload to the tweeters of your speakers. Always start tuning the high
band processor with the HIGH MIX control completely turned to the left.
11. PHASE INVERT switch: To add more bass punch, a subwoofer can be
connected to the subwoofer output. Sometimes the conductors of the subwoofer
are inversed which results in poor sound quality with a lack of low frequencies:
the opposite of what you expected! This can be corrected by inversing the (+) and
(-) poles of the cabling to your subwoofer or ... by pushing the PHASE INVERT
switch! Press the phase invert switch and compare the results of both positions.
The position with the most bass production is the right one!
12. X-OVER FREQ. control: (crossover frequency control) adjusts the cutoff
frequency of the subwoofer low pass filter. This crossover frequency can be set in
a range of 100 to 250Hz. Once again it is up to you to adapt its position to your
own taste. For most subwoofers 100Hz to 150Hz seems to be the best choice.
13. OUTPUT control: Controls the level of the subwoofer output from zero to +12dB.
Start from zero and slowly turn in clockwise direction until the amount of low
frequencies seems to be OK for you.
14. CLIP LED: When the subwoofer output level is too big, clipping may occur. In this
case the clip led turns on. No problem if the led blinks from time to time. However
when this happens too often, it's time to lower the subwoofer output signal.
Note: Clipping means deformation and deformation means possible damage to
your subwoofer...
15. LED BAR: Small led bar indicates the output level of both enhancer outputs.
