Pass Thru Output
In some very high performance systems, particularly AV systems, multiple subwoofers may be used. When the VPS 210 is used
in such a system the Pass Thru output can be used to supply a signal to a second subwoofer. The signal from this output is not
aected by the VPS 210 internal crossover. It is the same as the signal that goes into the inputs.
Control Setting and Operation
The VPS 210 controls are located on the top of the cabinet.
The Volume Control is on the left. The other controls are
under a removable cover. To adjust these controls, lift the
tab on the right side of the cover to remove it.
Power O/Auto/On Control and Status Indicator
OFF – Turn the VPS 210 o if you will not be using it. When
the switch is set to “O” the VPS 210 is Energy Star® quali-
ed.
AUTO – The VPS 210 will turn itself on whenever an input signal is detected. If no signal is detected, after several minutes it
will automatically switch to Standby mode. When the VPS 210 is in Standby mode it uses very little power.
ON – The VPS 210 is always on.
The Status indicator shows the VPS 210 power mode:
OFF – The subwoofer is o
AMBER – STANDBY (No signal detected, Amp O)
BLUE – ON (Signal detected, Amp On)
Volume Control
Start with the Volume Control at the 11 o’clock position. If the VPS 210 does not produce sound check the Status Indicator – it
should be lit blue. If it is not lit check the AC-line cord, Power switch, and input cables. (Are the connectors on the cables mak-
ing proper contact? Is the AC-line cord connected to a “live” receptacle. Is the subwoofer in either the Auto or On position?)
Adjusting the Crossover Control
When using the Line Level inputs (not the LFE input) the VPS 210 built-in crossover is engaged. As a starting point, set the
Crossover Control about 10Hz higher than the lower limit of your main speakers’ bass response. Fine tune the crossover set-
ting by ear for the smoothest blend with your main speakers. The best setting for the control will depend on the main speaker
used in the system, the placement of the speakers, and personal preference.
Once you have set the Crossover Control you may want make additional adjustments to Volume Control setting until the
transition from main speakers and the VPS 210 is smooth and the sound is balanced. Bass output should not overpower the
main speakers but rather be adjusted so there is a natural blend across the entire musical range.
Polarity Control
Selects regular (0°) or inverted (180°) phase for the VPS 210. Set this switch so the system produces the fullest, most dynamic
bass. The eect of phase will be most audible on low-frequency percussion instruments or music with a steady bass line.
