Interconnect cables
Whe n installing your VA-810/1012XII using the line-level inputs/
outputs, you sho uld use standard shielded phono cables. Always
keep the lines as short as practical to minimize noise.
When using the speaker-level inputs/outputs, use the same quality
spea ker cable to your subwoofer as you run to your satellites.
'/ac
em
ent
The VA-81 0/1012XII operates at very low frequencies which are
primarily non-directional. While it is recommended that the sub-
woofer be placed on the same plane as the satellite speakers, room
and system conditions often dictate otherwise. See your dealer for
help in placement.
' When using a pair of VA-810/1012XII subwoofers in stereo, it is
preferable to place each subwoofer adjacent to the satellite of the
as 100-120hz) than you would with larger speakers which have
greater low frequency output. With larger speakers, you mighi start
with this control set lower, such as 80hz.
A bypass switch is also provided if you wish to use an external
crossover. If you are not using an external crossover, we recom-
mend that you use the one provided within the unit for optimum
performanc e.
Phase adjust
ment
This control allows you the ability to compensate for having the
subw oofer in a different locat ion than the main speakers. Ideally,
you will have the sound from the subwoofer reach the listening
position the same time as the sound from the main speakers,
However,if the distance from the listen ing position to the subwoofer
and thedistance from listen ing position to the main speakers differs ,
the sound from each will reach your ears at a different time.
This control allows the signal to be delayed 180 degrees so the
output of the subwoofer will blend in to that of your main speakers
without any cancellation.
Auto
turn
on
switch
The auto turn on switch allows the user to bypass the auto turn on
functi on ifdesired. When set in the "auto" mode with main power on,
the VA-1008/121Owillturn itself on when an input signal is present.
If no signal is present, after several minutes the unit will shut itself
off. When set in the "on " mode, the auto turn on/off function is
bypassed and the unit will be on whenever the main power switch
is on.
High
pass
cro
s
sover
switch
This switch selects the frequency for the high pass crossover. This
crossover is functional on both line and speaker-level outputs.
Smaller speakers with limited low frequency output may prefer the
higher 100hz se
lli
ng which will reduce the low frequencies sent to
them. Larger speakers with greater low frequ ency output may be
able to handle the 80hz setting without strain.
Power
switch
The masterpower switch is located on the right half of the unit. This
rocker style switch is the main
onloff for the unit. This switch should
con tin ued.
