Due to the extreme efficiency of the amplification modules, they
deliver and draw current extremely quickly. Hence, you may find that
a very loud bass drum thwack will cause your lights to dim, or the
circuit breakers to trip if you do not supply enough power to your
system.
A possible solution will be to install an additional 20amp circuit in your
listening room for each channel of the bass. Also, the Maximum
Dynamic Headroom Reservoir (developed for the Genesis Reference
Amplifier) is available as an optional upgrade in some extreme
situations (that we have not yet encountered in all our testing!!)
2.4 Crossover Controls
You will notice two control knobs on the crossover box. The left hand
knob is a volume control for the rear tweeters. Turning this control
clockwise will increase the level of the rear tweeters. Use this control if
you need a bit more treble or to increase the apparent space of the
soundstage. Start with this control at the twelve o'clock (high noon)
position.
The control on the right side is a five-position switch used to adjust
midrange response and the soundstage height. Depending on your
room acoustics and your amplifier, position two has the sound stage
at about the middle – like the soundstage when you are seated in the
stalls seats in the middle of a concert hall. Position five pushes the
soundstage high, like the orchestra level seats, and position one has
the lowest soundstage – like you are in the balcony seats.
3 Tuning the system
Music is the best way to begin your setup procedure. We suggest that
video and movie sources be used only after you have setup the
system to properly reproduce music.
We suggest that you start with a single female vocal with instrumental
accompaniment because the sound of the human voice is more easily
recognizable than many instruments and is the least complex sound
to deal with.
3.1 Begin with the bass level
For now, leave the low-pass filter set at 98 Hz, This control will be
addressed later. Turn the volume control of the woofer amplifier up or
down until the voice sounds correct. Whatever controls you use, turn
them up and down only a little at a time. It is easy to turn it up or down
too much.
