Adjustments
4. On/off power switch.
Once the Z-Sub is positioned in the room and the
proper cables are installed the On/Off switch should be engaged in the
on position for initial power up. The LED turning red indicates the unit is
powered on.
5. Auto/On switch.
In AUTO position, the amplifier is in stand-by mode
and turns on automatically when the signal arrives from the amplifier or
receiver. It turns off after about 10 minutes when a signal is not present.
In the ON position, the amplifier is always on regardless of the presence
of a signal. The AUTO position is recommended for normal operation.
6. Phase switch.
This switch is specifically designed to eliminate phase
discrepancies between the Z-Sub as well as the primary LCR loudspeaker’s
phase. The phase relationship depends on the relative distance between
the sub and loudspeakers. If your sub is located within five feet (1.5m)
from either loudspeaker or between them, try the switch in the 0 degree
position. If your sub is located further away than that, experiment with
both switch positions and choose the position where you experience fuller
bass.
7. Low frequency cut-off control.
This allows adjustment of the cut-off
frequency (within 50-150Hz) of the subwoofer’s low pass crossover.
When using the sub for two-channel stereo, the knob should be adjusted
to match the primary loudspeakers’ low frequency roll-off to create a
seamless integration between them. For home theater, set the subwoofer
at 150Hz while setting your processor/receiver to crossover the system at
80Hz or 100Hz.
8. Volume control.
This control adjusts the loudness level of the subwoofer
and matches it with the loudness level of the loudspeakers. Adjust the level
to achieve a balanced sound between the subwoofer and the loudspeakers.
your room, source material and your preferences will determine this.
