The display will flash to identify that the volume function is being
adjusted. When you first press one of the volume control
buttons, the currently-set volume will flash. The next press will
move the volume up or down. Pressing and holding the button
will move the volume up or down rapidly.
Next, adjust the phase with the buttons marked “ PHS ” or “ PHS ”
on the remote control . When you first press the phase up or down
button, the display will flash “Ph” and then the current phase setting
will be shown. The next press of the button will move the phase up
or down.
Set the phase to zero to as an initial setting. (If you are not driving
the servo-bass amplifier as recommended using the output of the
power amplifier, the phase will depend on the phase shift of your
power amplifier. A typical value will be 45 to 60 degrees.)
The high-pass (HI) filter determines how low the woofers will play.
Set this initially to 20Hz. Next, adjust the low pass (LO) filter (how
high the woofer goes). Set this to 95 using the button marked "low
pass" (on the remote control).
You will notice two controls on the back of the midrange tweeter
panel. 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 position.
The control on the right side is a three-
position switch used to adjust the
midrange. Start at position two. Position
one will sound fuller in the lower midrange
while position three will sound leaner and
have more upper midrange.
The less obvious effect of the midrange control is to make the
soundstage sound more forward, and change the perceived height
and position of the performance. Relative to position two, you can
raise the soundstage by moving to position three (it’s like moving
your seat forwards in the concert hall!!)
