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
