ELECTRONIC CONTROLS
The Model 10 Crossover/amplifier has much greater adjustability than any conventional speaker. With it, you can
best match the speakers to your room and personal preferences. Such a powerful tool can also be misadjusted and
make the speakers sound awful, so please read the following information carefully:
There is a master switch on the back panel that turns on the Crossover/amplifier. It is designed to be left on
continually. T he Crossover/amplifier is highly efficient, uses very little electricity at idle, and runs cool.
Components will last far longer if they are not subjected to repeated turn-on surges. So it is best to leave the
crossover/amp on continually, there is no reason to turn it off. Also, if you turn it off, you will have to reset its
levels when you turn it back on.
Level
This controls the overall level of the sound. It controls both channels simultaneously and has 100, 1 dB steps. It is
a volume control and you can use the crossover/amp as a preamp if you only have a single source. But normally,
you will be using a preamplifier, and the level control is designed so that you can obtain the optimum sensitivity of
your preamplifier's volume control. You should set the Crossover/amp level so that you use most, or all of your
preamplifier's volume control when playing music at the loudest level. This way, you will have the most sensitivity
and linearity from your preamp's control.
The crossover/amp's level control is the finest available and better than those available on most preamps. So you
may find it best to turn your preamp up about to a loud position, then use the crossover/amp's level control to adjust
the volume of your system. Not only does it work well, the digital readout makes it easy to see where you are and it
can be remote controlled.
Adjust this control to “90” on the digital readout when you are starting the unit for the first time. You can adjust it
more precisely later. M ost systems will use the range from 80 ( 10 dB below unity gain) to 90 ( unity gain).
"Passive" preamps may benefit from turning the level control up t o "99" so that you have more output level
available. Feel free to use whatever value best fits your system.
If you have a single source such as a CD player, you can connect it directly to the crossover/amp without using a
preamp. Use the level control on the crossover/amp to adjust the volume.
