Subwoofer Placement & Time Alignment

Although you can place the ROCK SHAKER subwoofer in a variety of locations within your listening environment, you’ll enjoy the best performance when it’s on the same side of the room as your system’s front speakers. You can also place the subwoofer in a corner or near a wall to increase its loudness. Be sure to place it feet-side down and, if at all possible, away from an open doorway. Ultimately, the best way to learn where in the room you can achieve optimal sound quality is by placing the sub in different locations.

Please note: Avoid placing near video monitors. Allow at least 1 a’ of space between your subwoofer and any television. If you notice any distortion or discoloration, immediately move the subwoofer away from the TV.

Configurations (ROCK SHAKER 8 PICTURED)Receiver w/Subwoofer Output

In this configuration, you’ll feed the subwoofer out signal from the receiver to the EITHER the left OR right Line In RCA jacks of the subwoofer using a monaural RCA cable (single RCA to single RCA). Since this unit does not feature an LFE (Low-Frequency Effects) input, be sure to turn the Frequency knob to the 150Hz position. This will make the Line In RCA jacks into LFE inputs. You can also connect your receiver’s Pre-Out RCA outputs to the subwoofer’s Line In RCA inputs.Alternately, you may use a Y-split RCA cable (single RCA to dual RCA) to feed the subwoofer out signal from your receiver to the left AND right Line In RCA jacks of the subwoofer.

Configurations (ROCK SHAKER 8 PICTURED)Receiver w/No Subwoofer Output

If your receiver does not have a subwoofer output, you have two options for connecting your subwoofer.

In this configuration, you feed the left and right Front Channel speaker signals from the receiver to the corresponding High-Level speaker inputs on the sub. Then you feed the Left and Right High-Level speaker output signals from the sub to the corresponding front channel speakers.

Please note: When using the High-Level inputs DO NOT use the Line In RCA inputs.

Settings

Auto On/OffSlide this switch to the “AUTO” position and the unit will turn on automatically when it senses an input signal. If there is no signal for 15 minutes, the Auto circuit will turn off the subwoofer. If the switch is in the “ON” postion, the unit will be powered on all the time. Slide the switch to the “OFF” position and the unit will receive no power.VolumeUse a variety of audio signals to properly adjust the subwoofer’s volume level.FrequencyThis knob adjusts the frequency input to the subwoofer. Depending on your speakers’ bass output capabilities, set the crossover frequency on the receiver to 80Hz for tower and bookshelf speakers (speakers with a woofer 5’/4- in diameter or larger) and 100Hz – 120Hz for satellite speakers.Phase SwitchIn order to properly set the phase switch, you have to find the subwoofer’s crossover point. We recommend playing various types of music with prominent baselines. Listen for the transition point. This is the moment during audio playback that the subwoofer transitions to your main speakers. Whichever phase setting sounds louder when the subwoofer transitions is the optimum setting.
