and the midway position.
Adjusting the controls
Once you have completed the settings you
should prepare to fine-tune the subwoofer
controls. Choose a multi-channel disc with
natural bass qualities - a music disc is best.
Adjust the control on the subwoofer's rear
panel marked PHASE to tune the blend
between the subwoofer and speakers.
Depending on your room acoustics the
sound will be fuller and more coherent with
the switch in the 0° or 180° position. Use
your judgement to set the switch to the best
sounding position.
On the e8as2 you also have fine control
over phase. Use the variable PHASE control
to achieve the fullest and clearest bass
response. In conjunction with the PHASE
switch, the phase can be varied over 180°.
Adjust the SUBWOOFER VOLUME control to
give bass output that is in balance with your
main speakers. Initially you may prefer the
subwoofer output at a relatively high level,
but this can become tiring, with an over-
emphasis on bass on extended listening.
Turn the volume down by degrees until the
subwoofer is not heard individually but
rather as an extension to the main
speakers.
On the e8as2 you can fine tune the bass
performance to suit your room. If the bass is
boomy, or appears uncontrolled at very low
frequencies, switch the SUBSONIC FILTER to
ON. Adjust the BASS CONTOUR to control
output at the very low frequencies.
