To allow for the addition of further EM15's and balance control between the
EM15's and the EM150, a further power amplifier may be added to the
system as shown in Fig 3. The same signal is fed into both amplifiers, one
driving the EM15's, the other driving the EM150.

An EMX1A controller may be used to further increase the flexibility of the
system (see Fig 4). With an EMX1A controller the relative levels can be
balanced in the controller. The EMX1A also provides signal limiting for
driver protection and has a 120Hz electronic crossover, removing signals
below this point from the EM15's.
