R8DT SUBWOOFER

Method B (Most universal installation, least desir- able sonically)

This connection method allows the subwoofer to be used with virtually any audio system, but its audio output is not as clean as when line in inputs are used as in Method A.

Connect speaker wire from the amplifier/receiver’s main Left and Right outputs to the speaker level input on the subwoofer. Using the same size speaker wire, connect the speaker level outputs from the subwoofer to the main Left and Right speakers.

This method directly connects the main Left and Right speaker inputs to the speaker outputs, but the sub- woofer amplifier taps onto the speaker level signal to get an audio feed. This signal, being previously amplified by the amplifier/receiver, is not only too strong but also contains a certain percentage of distortion relative to the audio signal. This percentage (the lower the better) should be specified in the amplifier/receiver’s manual. This signal is internally reduced to feed the amplifier for the subwoofer which will not only re-amplify the audio but also any distortion present in the signal as well.

PLACEMENT

The R8DT subwoofer uses the sonic reflective qualities of an on-floor, corner placement to achieve optimal sound performance. The closer it is placed to a corner, the more emphasized the bass will sound. The R8DT should also be placed close enough to the audio system so that cables and wires are as short a run as possible.

Installation tip: put the subwoofer in the location where the seated listener would be connect the subwoofer and adjust for best sound. Move around the room and you will hear a difference in the subwoofer output based on your location and how the room acoustics affect it. Find the area where the subwoofer sounds the best and that is where the subwoofer should be placed. The crossover point and the volume level may be retuned to compen- sate for slight changes that may be needed.

ADJUSTMENTS

To start, set the crossover control to its center position. This adjustment selects the frequency where the audio will start to be filtered out. The higher the setting, the more signal range will be allowed, increasing output along with frequency range. Too high a setting can cause poor sound if the subwoofer is covering frequencies that are not in need of reinforcement, e.g., main speakers and subwoofer covering the same range may create undesirable levels of mid bass notes.

Phase selection can compensate for subwoofer place- ment that is irregular or too far from the listener in rela- tion to the main speakers. Low frequencies have long wavelengths that have peaks and low spots. If these do not align with the main speakers, there can be bass cancellation. Reversing the phase will correct this.

Set the volume level control fully counterclockwise to mini- mum. This should be reset after making other adjustments.
