INSTALLATION AND SETUP
For sealed enclosures, use DBO to
enhance the middle of the bass region.
Set the HP FREQ control to 35Hz to
40Hz and adjust the BOOST control to
taste. This will make the bass sound
bigger and fuller. Alternatively, for
tighter-sounding bass, set the HP FREQ
control between 45Hz and 50Hz,
and also adjust the BOOST control
according to your preference.
For infinite-baffle applications, set the
HP FREQ control to the speaker’s F
S
value (to keep the subwoofer from
trying to create bass below the
resonant frequency) and adjust the
BOOST control to taste.
INSTALLING NEON
TUBES (OPTIONAL)
1. Using a Phillips screwdriver, remove
all screws on the amplifier’s
output/power end panel and set
them aside.
2. Using a 3 ⁄32-inch Allen wrench,
remove only the screws on the
amplifier’s (top) clear cover and set
them aside.
3. Remove the end panel and slide the
cover off. Set both parts aside.
4. Locate the enclosed hardware bag
and remove the four clips. Each clip
has a square end and a larger round
end. Using a round end, press two
clips onto each neon tube (e.g.,
Street Glow AN9 or equivalent), as
shown in Figure 9 below.
5. For each tube, align both clips so the
square ends slide onto an exposed
extrusion edge, as shown in Figure 9.
Do not cover any screw holes. When
installed correctly, each neon tube
will sit under an extrusion and not be
visible when viewed from directly
above.
6. Route each neon tube’s power cable
through its respective NEON hole on
the end panel (see Figure 9).
7. Slide the cover back into place and
reinstall its screws. Then, replace
the end panel and reinstall its
screws.
8. Finish the installation of the neon
tubes as instructed in their owner’s
manual.
