INSTALLATION AND SETUP
TROUBLESHOOTING
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.

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.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.
