Bass Boost
This amp has a fully adjustable bass boost. Both the frequency and the level of the boost are adjustable. Start with a small
increase in the level control. then "sweep" the frequency up and down. Listen carefully for an improvement in the sound of
the bass. If you do not hear any improvement then the
woofer does not need any boost.
WARNING: Use Bass Boost carefully. The demands on
power output are tremendous. Try to minimize the use by
changing woofer position or the enclosure size.
Subsonic Filter
A subsonic filter acts like a crossover but at very low frequencies. It removes frequencies that are so low the speaker
cannot reproduce then. You see the cone moving but hear no sound. This can be very hard on your woofer especially at
high power levels. If you are using a ported
subwoofer enclosure at high power you should
use a Subsonic Filter to limit cone movement at
very low frequencies.
Speaker outputs
This amplifier is a Mono Block design. Meaning it has only than one channel of speaker output. It is equipped with a large
removable plug style terminal for speaker wire connections up to 10 AWG. Make this connection carefully and neatly.
Strip your wire back 5/16" and twist the exposed leads. Insert them into the block terminal while being careful that there
are no loose or frayed strands of wire. Tighten the set screw
down on the terminal until the wire is tightly secured in place.
If the wires ever come in contact with each other the ampli-
fier will go into protection.
WARNING: Know your total ohm load before you make
any connections.
Strip Speaker Wire
Note: The XDi 1100.1 has 2 speaker connectors. This is NOT a 2
channel amplifier. These terminals are internally connected on the
circuit board and do not represent individual channels. These connec-
tors are strictly for the convenience of the installation of multiple
subwoofers.
