CHAPTER 9
Project EVEREST DD66000 Connections
Caution: Turn all amplifiers off before connecting or disconnecting Project
EVEREST DD66000 loudspeakers. Making connections while an amplifier is
operating could seriously damage the loudspeaker system and void the
warranty. All amplifiers must also be turned off before connecting or
disconnecting cables at the amplifier or preamplifier inputs.
All connections between the amplifier(s) and the Project EVEREST DD66000
loudspeaker system are made at the terminals located on the back of the
enclosure. The left-hand terminals (black letters) are negative, and the
right-hand terminals (red letters) are positive. These correspond to the negative
and positive conductors in the speaker wire.
Assign one of the two conductors as the negative conductor and the other as the
positive conductor. Use these same designations for all system wiring. Always
connect the conductors of the speaker wire appropriately to the corresponding
negative and positive terminals on all system components. This will ensure that
all components will work together ("in phase"). Connecting the speakers out of
phase will not damage them but will result in reduced low
frequency output and impaired stereo effect.
Speaker wires may be fastened to the terminals by several
methods. The most positive connection is made by directly
connecting clean, bare connectors (exposed by stripping the ends
of the wire) to the terminal posts.
For this type of connection, loosen the knobs on the terminals
and insert the exposed (bare) ends of each speaker wire into the
hole exposed on the terminal shaft (+ to +, - to -). Retighten the
knob on each terminal so that a snug positive connection is
achieved. Do not apply excessive force and do not overtighten.
To avoid a short circuit, trim off any excess wire that is not in
contact with the binding post contact surfaces.
Project EVEREST DD66000 terminals are also designed to
accept spade or banana-type connectors which are fastened to
the ends of the wires and, in turn, are attached to the terminal
posts.
2 sets of input terminals of Project EVEREST DD66000 are compatible with
