Velodyne Acoustics SPL-1000R, SPL-800R 1LOW-PASSCROSSOVER, 2VOLUME Control, 3AUTO ON/OFF Switch

(1)LOW-PASS CROSSOVER

Use this knob to select the high-frequency range at which you wish to cut 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, the speed at which the power light blinks indicates subwoofer volume - the faster the blinking, the louder the unit plays. After the volume blinking stops, the unit will blink out the actual volume number. Slower blinks represent tens, and faster blinks represent ones. So, for example, if the volume were set at 34, after the rapid blinking stopped you would observe three slow blinks followed by four faster blinks, indicating a volume of 34.

NOTE: Volume is also controllable by using the supplied remote, when defaults are restored. The default is 30 out of 100.

(3)AUTO ON/OFF Switch

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

(4)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 and feed the signal into both “R” and “L” inputs.

(5)LINE OUTPUT

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