Rear Panel Connections

Figure 1 shows the connections on the rear panel of the DLS-R.

Following are brief descriptions of the connections described in Figure 1. More detail on these connections can be found on the next page.

(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.

Note: Volume is also controllable by using the supplied remote.

(3)AUTO ON/OFF Switch

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

(4)LINE OUTPUT

Connect these jacks to the LINE IN preamp input to use the DLS- R’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 and feed the signal into both “R” and “L” inputs.
