MiniVee User’s Manual
I n p u t s
Your new subwoofer is equipped with speaker-level and line-level inputs. Use the LINE LEVEL
jacks when connecting your subwoofer to a pre-amp, signal processor, line-level crossover or
receiver with pre-amp level outputs. The
SPEAKER LEVEL jacks connect directly to the speaker
outputs of any amplifier, integrated amplifier or receiver. Your amplifier section will notice no
additional loading effects when you use these inputs due to their very high impedance.
Important!!!
Do not use both LINE LEVEL and SPEAKER LEVEL connections simultaneously!
V o l u m e C o n t r o l
This control allows you to balance the output from the subwoofer to the main
speakers/amplifier in your system. This control should be set to achieve similar output level
from both the main speakers and subwoofer when listening to music. A good starting point for
the volume control is 3 or 4 dots from minimum.
L o w - p a s s C r o s s o v e r - 4 0 t o 1 2 0 H z
All inputs sum the left and right channels together, with the resulting signal passing through an
adjustable low-pass crossover before being amplified. The crossover control allows you to adjust
the upper limit of the subwoofer’s frequency response from 40 to 120 Hz. The subwoofer’s
response will begin rolling off above the frequency you set this control to. You should set the
crossover frequency to obtain a smooth and seamless transition from the subwoofer to the
main speakers in your system. If your main speakers are smaller units with limited low frequency
output, you may wish to choose a higher frequency (such as 100 -120 Hz) than you would with
larger speakers which have greater low frequency output. With larger speakers, you might start
with this control set lower, such as 80 Hz.
A bypass switch is also provided if you wish to use an external crossover. If you are not using
an external crossover, we recommend that you use the one provided within the unit for
optimum performance!
P h a s e A d j u s t m e n t - 0 ° / 1 8 0 °
This control allows you to “reverse” the phase of the subwoofer’s output signal 180° to correct
for any possible mismatch and resulting cancellation between the subwoofer and your main
speakers/amplifier. To adjust, simply listen to the system with music playing. Then move the
switch from one position to the other and listen for a change in low frequency output. The
correct position will have a greater amount of apparent low frequency output.
C r o s s o v e r S w i t c h - I N T E R N A L X - O V E R / S U B W O O F E R D I R E C T
This switch allows the internal crossover circuitry to be removed from the signal path. This is
required in certain installations which route the signal through external processors with a
crossover circuit of their own, such as the new digital units. Simply move the switch to
SUBWOOFER DIRECT to disengage the built-in crossover. For all other installations which do
not have a separate electronic crossover, we recommend you leave the switch set to
INTERNAL X-OVER to provide optimum performance.
