Listed below are the eight possible configurations when using the
SLF-1 crossover module.
• The module slots are configured in series, this amplifier has the
capability of 12 dB/octave high-pass, low-pass, or bandpass
operation. 24 dB octave high-pass or low-pass operation is also
possible. An additional module Is required for bandpass or
24 dB per octave operation.

INSTALLATION
This section details the mechanical and electrical procedures you
will need to perform the installation of your ORION amplifier. Take a
moment to look over the list of precautions, tools and additional
parts needed to successfully complete the job.
GENERAL PRECAUTIONS
Before installation, make sure you pick a location that will provide
adequate ventilation around the amplifier. The ORION amplifier has
massive heatsink fins to couple generated heat to surrounding air
space via thermal conduction. However, if the amplifier is mounted In
a tight space without any air movement, over time the amplifier can
fail, in spite of its thermal protection circuits.
Therefore, we recommend that you mount the amplifier flat on
the floor under the front seat or in the trunk. Remember, heat travels
up away from the heatsink fins. In addition, please observe these
precautions:
• Do not enclose the top of the amplifier unless you
have a cooling fan.
• Direct cool air along the length of the fins, rather than across
them, for the most efficient cooling. Remember, any moving air
will dissipate heat.
Note: When two low-pass filters of the same frequency are
used for 24 dB per octave operation, the cut off
frequency will decrease by 20 percent.
When two high-pass filters of the same frequency are
used for 24 dB per octave operation, the cut off
frequency will increase by 20 percent.
