RIGHT ANGLE HEADER CONNECTOR LOCATING INSTALLING THE LFQ 45 STEP 2: Adjusting the LFQ 45 A. The LFQ 45 provides +4, +8 or +12 dB of Bass Boost at 45 Hz with a "Q" of 3. This frequency and "Q" combination was chosen to enhance overall bass response. To adjust the level of Bass Boost, move the LFQ 45's jumper to one of the three available positions. Make your initial Bass Boost adjustment to the LFQ 45 prior to installing the module in the amplifier. We suggest starting with the jumper in the +8 dB position. After listening to your initial setting, if you wish to adjust the Bass Boost, turn the amplifier off prior to moving the Bass Boost Jumper.
