1LOW-PASS Crossover | Velodyne Acoustics 8, 12, 10 instruction

Following are brief descriptions of the connections described in Figure 2. More detail on these connections can be found in the next section.

(1)LOW-PASS CROSSOVER

Use this knob to select the frequency above which you wish to roll off the signal to the subwoofer. When the knob is turned all the way to the left, the Subwoofer Direct feature is invoked and the subwoofer plays all frequencies up to 200 Hz.

(2)VOLUME Control

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 volume level from between both the main speakers and subwoofer. When pressing volume up or down, set the level while watching the LED display for reference. The upper button increases the subwoofer level and the lower button decreases it.

Note: Volume is also controllable by using the supplied remote. When defaults are restored, the default volume setting is 30 out of 80.

(3)AUTO ON/OFF Switch

Use this switch to select between auto-on (active) and constant on (auto-on inactive) operation.

(4)LINE OUTPUT

Connect these jacks to the LINE IN amp input to use the Optimum subwoofer’s internal high pass crossover. See below for a more detailed explanation of this crossover.

(5)LINE INPUT/LFE Input

Connect these jacks to the LINE OUT preamp output, LFE output or subwoofer output jacks of your receiver/processor. If using the LFE output from your receiver or processor, plug the single cable into the “L” - LFE input or for more signal, use a “Y” connector (not included) and feed the signal into both “R” and “L” inputs.

(6)SPEAKER LEVEL INPUT Terminals

Connect these input terminals to the speaker output terminals of your amplifier or receiver. If you use this method of connection, when you go to the receiver speaker set up menu, make sure you select the large speaker option.

(7)IR Input

This is a connection to allow you to purchase a third-party infrared remote sensor or an extended cable for placement closer to your other remote controlled equipment. This keeps you from awkward control angles using the infrared remote control.

(8)12v Trigger

When this mini jack is connected, the unit remains in power-off mode until 12 volts is supplied across the two leads. There is no polarity requirement.
