CHAPTER 8
Project EVEREST DD66000 Switch Operations
The EVEREST DD66000 has 2 control panels under
the cover at the center bottom of the front baffle.
Shorting bars or switches inside the control panel
enable to switch orientation of the system and
biamplifier and also to adjust woofer and
high-frequency levels. They also provide access to
the 9-volt batteries used for capacitor bias. Remove
the control panel cover referring the illustrations on
the right, and make necessary adjustments.
To change setups using shorting bars, use the
supplied hexagonal driver to remove the screws
fixing the bar. Then, move the bar according to setup you prefer. Then, put
screws back.
Attention: As loose mounting screws on the terminals could cause bad contact,
make sure that they are firmly affixed. However, if you screw too strong, there
is a risk of damaging the terminals themselves. Please use the supplied
hexagonal driver and tighten screws with reasonable torque.
The Project EVEREST DD66000 can set up and adjust the following by using
the above procedures.

orientation jumper bars can configure a single DD66000 system as either a "left
or right" system. It is necessary that both bars be moved together. Improper
sound will result from staggering the bars. The bars select which woofer
