Operation Manual

If using the video output display, night mode shows as active below the Preset note on the Introductory screen. Night mode can be modified in

the “Next” page of either the video output menu or the Windows Setup Program.

ctive, Inactive & 12V Trigger Power Modes

The subwoofer has three power ON modes. These modes help the user control power conservation when the subwoofer isn’t playing,

ut allow the subwoofer’s power switch to remain ON at all times.

• In the active mode, the subwoofer’s standby mode is on. When the subwoofer gets an audio signal input, the internal amplifier turns on

to play the audio. It takes a few seconds for the DSP processor to boot-up and then you hear the audio.

• If the subwoofer is in active mode and doesn’t receive an audio signal, the subwoofer automatically goes into standby mode to save

power. This takes between 10 to 15 minutes.

• In standby mode, the subwoofer’s power switch is ON and its internal amplifier isn’t on.

If the subwoofer will be left in standby for a period of greater than 5 days,

Velodyne recommends turning off the power switch.

• In the inactive mode, the standby mode is defeated.

• In the inactive mode and when the subwoofer power switch is ON, its internal amplifier is on even if the subwoofer isn’t receiving

an audio signal.

If the subwoofer will be left inactive for a period of greater than 5 days,

Velodyne recommends setting the power switch to OFF.

• In the 12V trigger mode, the subwoofer turns on with a 12V source (from a controlling receiver) at its 12V trigger jack.

• In 12V trigger mode and when the subwoofer’s power switch is ON, its internal amplifier isn’t on until it receives 12V in either polarity

at the 12V trigger jack.

• In 12V trigger mode, if the 12V trigger is not applied, the subwoofer will not respond to the remote control. To reset the mode, apply the

trigger and then use the remote or Windows Setup Program to effect the change.

If the subwoofer will be left inactive in 12V trigger mode for a period of greater than 5 days,

Velodyne recommends setting the power switch to OFF.

Light Mode

When the light mode is OFF, the LED display behind the front grille is always off, except when momentarily lit to show a change in the volume

or crossover settings or the status of the Auto-EQ

PLUS

process. When light mode is ON, the LED display always shows the volume, except it

does reflect changes in crossover settings or the status of the Auto-EQ

PLUS

process and then reverts to volume. Having the LED on at all

times can be distracting in a darkened listening room, so the default setting is OFF.

Protection Circuitry

The subwoofer is equipped with protection circuitry to provide maximum performance with greatest reliability. The subwoofer is

protected against:

• Overdriving the speaker

• Overdriving the amplifier

• Overheating the amplifier

• Excessive drop in power line voltage
