we would expect it to be. This may be due to the fact that very few
microphones provide reliable feedback in the low frequencies.
2-channel only
:
On the subwoofer’s amplifier there is a volume-like
control (labeled, “Frequency”) that indicates a range of 30 (turned
fully counter-clockwise) to 200 (fully clockwise). This is the range—30
Hz to 200 Hz—of crossover frequencies offered by The Uinta™
Subwoofer
(110volt U.S. amp version)
. Determining an appropriate
crossover frequency and “integrating” the low-frequencies with the
main speakers will involve rotating this control until the bass has the
right overall “color,” or timbre.
Integration, stereo inputs:
To determine the “best” crossover point, we
recommend that you listen for transient and timbrel continuity. If the
bass seems too “thick,” turn the knob slowly counter-clockwise. If it
seems lacking in “fullness,” you may need to turn it clock-wise. The
bass should sound “faster” and more precise. Too low of a crossover
point will reduce the sense of low-frequency “energy”--besides calling
undue attention to the bottom octave. Too much overlap will make the
mid-bass sound wooly, muddy, and slow. When the crossover is
adjusted correctly it should sound as if the subwoofer were part of the
satellites, or invisible. Turning the subwoofer amp on and off should
provide the only indication of the subwoofer’s presence. (It may
require level adjustments, and burn-in, before the blend is seamless.)
Integration, LFE input: If the audio signal enters the Uinta via the LFE
input, the internal crossover will be defeated. This allows the
surround-sound processor to control the crossover point. Under these
conditions, follow the instructions detailed in the processor’s owner’s
manual. However, we still recommend that you listen for the same
bass characteristics detailed in the preceding paragraph.
Finally: If your set-up, and/or personal preferences, allow for a more
fastidious “tuning” of the low frequencies, you may wish to continue
with the following: After you find the crossover point which seems to
present the most accurate presentation, you’re ready to do the last
bits of fine-tuning. Without the use of a continuously variable phase,
be prepared to move the subwoofer forwards, or backwards, until the
“blend” is more musically correct. (“Continuously Variable Phase”
allows this type of “displacement”
without
moving the subwoofer.)
Once again, you’re listening for the sense of precision, speed, or
“forward movement” of the music--“pace and rhythm,” if you will.
