NOTE: Because QBASS is a boost only EQ system, it is easy to either clip the amplifier, or overdrive a speaker past its excursion limits. To make up for frequency response that is 10dB down (say at 45 Hz), 10X the amplifier power is required. This may tax both driver and amplifier. It may also exhaust the headroom in the DSP controller. This issue is especially problematic in vented (ported) speaker enclosures, where the cone excursion increases considerably below the port tuning frequency. If you hear any sign of bottoming, or other speaker or amplifier misbehavior, try reducing the amount of bass boost. This is also possible with any EQ band set to excessive boost.

NOTE: Although the input and output connections are labeled with typical application, any input can be routed to any output. The caveat here is to make sure that all of the presets that you plan to use contain the same routing. This can be easily accomplished by storing the preset to preset #1, recalling preset #1 (press the mode button, then the 1 button), then the left arrow, (to bring up the sensitivity menu) then pressing 2. Repeat this procedure for 3, 4, and 5. This only needs to be done at the initial installation.

The Remote Out contains a 2-sec delayed turn-on signal that can be used to extend the turn-on time of downstream devices (amplifiers).
