FEATURES AND SPECIFICATIONS SUBJECT TO CHANGE AND OR IMPROVEMENT WITHOUT NOTICE

A sealed enclosure causes a woofer’s frequency response to roll off

at  a  rate  of  12dB  per  octave  below  the  enclosure’s  resonant  fre-

quency.  The  bass  boost  circuitry’s  quasi-parametric  equalization 

provides a single octave boost of 12dB at 45Hz to ensure smooth 

and accurate bass response.

For a source unit having a single pair of signal outputs an adapter 

is  needed  to  split  the  source  signal  for  the  front  and  rear  inputs. 

With the mobile electronic crossover, by engaging the parallel input 

feature, an external adapter is no longer necessary.

This power supply design provides constant voltage to the cross-

over  regardless  of  the  battery’s  voltage  to  ensure  consistent  out-

put performance at all times. This design also eliminates switching 

noise sue to voltage fluctuation.

The mobile electronic crossover features front and rear preamp in-

puts  with  front  and  rear  outputs  as  well  as  constant  subwoofer 

output  that  is  independent  of  the  front/rear  fader  control  on  the 

source unit. 

The  front  high-pass  section  is  equipped  with  frequency  multiplier 

switch that can be used to multiply the crossover frequency points. 

With the additional selectable crossover points system setting be-

comes an art of precision.
