imPortant: When you use the bi-wire or bi-amp connection
method, remove the shorting straps from the terminals (referring
to the figures below) and re-tighten the knobs on the terminals. If
the amplifiers are connected to the Project Everest loudspeakers
in the bi-wire or bi-amp mode with the shorting straps still on,
the amplifier outputs will be shorted, which could result in costly
amplifier damage when power is switched on. The bi-wire connection method requires one amplifier channel and
two sets of speaker wires for each loudspeaker. After removing
the shorting straps, you can make connections to the individual
network sections using all four connectors, with one set of wires
to the upper (high-frequency) terminals and another set of wires to
the lower (low-frequency) terminals.
Bi-Amp connecTion meThod
The bi-amp connection method requires two amplifiers, one for
the low-frequency transducers and one for the high-frequency
transducers, and an external dividing network (electronic
crossover). After removing the shorting straps on the loudspeaker
connector panels, wires from the high-frequency amplifier are
connected to the upper terminals, and wires from the low-
frequency amplifiers are connected to the lower terminals.
Each of these connection methods described above has its own
advantages – your Project Everest loudspeaker system will deliver
superb performance with any of the methods described.
finaL checkList:
• Connect all other system electronics and plug into AC
power outlets.
• Check all connections. In case of bi-amping or bi-wiring,
make sure both shorting straps are removed.
• Make sure the system orientation and HF/LF drive jumper
bars on the control panels are correctly set.
The loudspeakers are now ready for use. The Project Everest
loudspeaker system is fully functional as soon as it is set up. There
may be subtle tonal changes in bass output over the first week to
10 days of operation. These are caused as the movement of the
low-frequency drivers becomes more fluid and the parts settle in.
This process is completely normal and natural with transducers of
this caliber. Even during this initial period, there is no restriction on
the amount of amplification that may be applied. Enjoy!
