This connection passes along the input signal from the MINI-JACK input unchanged.

These speaker level connections connect to your main speakers. There is 120 Hz high-pass
crossover that removes the bass frequencies from your main speakers. This frees them of the
burden of playing bass, which makes the entire system perform better.

This control allows you to balance the output from the subwoofer to the main speakers 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 three or
four dots from minimum.
WARNING:
Some manufacturers preset their receivers with the Sub-Out channel signal at a
minimum level. It is very important to verify that your receiver Sub-Out channel is set to the
same output level as your front right and left channels. Refer to your receiver manual for the
individual channel level adjustment procedure. If your receiver Sub-Out channel is set too low,
the subwoofer may appear to have a weak output, it may sound noisy or distorted, and the
Auto On/Off feature may not operate properly.
L o w - p a s s C r o s s o v e r - 5 0 t o 2 0 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 50 to 200 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 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.
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. 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.

This switch allows the MicroVee’s internal crossover circuitry to be bypassed. This is required
in certain installations which route the signal through external processors with a crossover
circuit of their own. 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.
NOTE: This is explained further in the section below entitled “A Word About Crossovers”.
