• Adjusting Volume Levels with the Gain Bass Knob
Use the Gain Bass knob to adjust the active subwoofer’s volume to suit the
venue and situation. If you want to increase or decrease the subwoofer’s
volume, simply turn this knob to the left or right (control range +/-6 dB).
If you hear distortion or the signal sounds saturated, fi rst check the signal
sources and, if possible, reduce the output signal level there.
• Adjusting the Corner Frequency:
With the X-Over Bass Switch (L SUB 1200 A, L SUB 2000 A)
You can use this switch to adjust the LINEAR active sub’s frequency range
to match the signal you wish to render and/or the surroundings. The Line
Out Mid/High Left/Right outputs are not aff ected by this setting.
With the Mode Switch (L SUB 4000 A)
Use this switch to adjust the frequency response of the active LINEAR
subwoofer to the audio signal and the surroundings. The Line Out Mid/High
Left/Right outputs are not aff ected by Mode changes.
If you add the L SUB 4000 A to an existing PA system as a deep bass
extension, Sub Low is the recommended setting. The LINEAR 5 range’s
acoustic and phase-corrected tuning ensure that the L SUB 4000 A works
with every model available.
• Adjusting the Phase Position with the Phase Switch
You can use the Phase switch to adjust the LINEAR active sub’s phase
position to match that of the connected mid/ high unit. Always set this
switch to 0° when operating the bass bin with LINEAR 5 mid/ high units.
You may have to invert the phase to operate this sub with other speakers. If
so, set the switch to 180°.
