Adjustment procedure
� Adjusting the cut-off frequency and volume
Use the cut-off frequency (FREQUENCY) and volume (OUTPUT LEVEL) knobs on the front of the subwoofer (SL105) and adjust the levels to the desired level in accordance with the layout of your room and the positioning of all your components. If the playback frequency range and volume of the subwoofer are not set to proper levels, distortions in the playback characteristics can result.
POWERED SUBWOOFER
FREQUENCY OUTPUT LEVEL

Although it is recommended to set the cut-off frequency and output level settings as high as possible, it is difficult to notice the extremely low frequency bass sounds. This makes it possible to accidentally set the volume level too high. In order to prevent this, back the levels down just a bit to ensure the proper balance. Note: Make sure that the input levels do not reach excessive levels. The HTP-L50 is designed for playing back music at a normal volume, but if the input levels are set to enormous levels, it may damage the speakers. Also, always first lower the volume at the amplifier before changing the settings of any switches to prevent accidental damage.

For details on how to connect the speaker cables, see the previous page. Notes: � When connecting the speaker cables, be sure not to mistake the (+) and (�) and the L (left) and R (left). If the speaker cables are connecting incorrectly, there will be a loss of fidelity in the bass sound ranges. � The speakers connected to the SL-105 SPEAKER LEVEL OUTPUT terminals must have an impedance equal to or greater than the rating indicated on the amplifier connected to the SPEAKER LEVEL INPUT terminals. Otherwise, amplifier damage may occur. � Do not use BTL (Balanced Transformer-Less) type amplifiers. Using a BTL amplifier may cause damage to both the amplifier and the subwoofer. Ordinary amplifiers are not BTL amplifiers. For details, see the amplifier�s instruction manual.
