Introduction
Thank you for your purchase of the Power2 amplifier.
Your investment in this product speaks volumes about
your uncompromising desire to experience the highest
levels of fidelity from your music and movie collection.
We could wax poetic about the inaudible noise floor,
bandwidth to channel 3 on your television and remark-
able phase accuracy of this amplifier. You can read all
about the specifications all you wish. While some of us
might find that interesting, the real heart of the matter
comes when you sit down and listen to your system. We
feel we have succeeded at the point when you have long
forgotten about the specifications, operating
temperature, or even the fact that you have an amplifier
connected to your system. All the watts, cables and
setup configurations should simply go away, leaving
nothing between you and the music.
Before you begin your journey to audio nirvana, we think
it's important that you invest a few minutes learning about
the proper setup and operation of the Power2. This will
insure your investment is maximized and the beginning
of the bragging rights associated with the pleasure of
possessing the most advanced amplifier on the planet.
We sincerely wish, that from this point forward, this were
the only reason you remember you even own a Power2
at all! Job done.
If you have any technical questions, please visit
nhthifi.com or call 800-NHT-9993.
Unpacking
Carefully unpack the Power2 and inspect all the contents.
Store all packing materials for later use, if possible. You
will need the packing materials, if you have to ship your
Power2 unit.

Placement
The Power
2
amplifier may be placed on a shelf, or in a
standard 19" equipment rack using the optional rack ears
and hardware. Proper ventilation is required so the
Power2 will not overheat. Two inches of open space
above and below the Power2 is sufficent for proper ven-
tilation.
Note: Due to the placement of the Power
2
power switch
on the rear panel, do not install the Power
2
in a wooden
box or similar enclosure where access to the power
switch is blocked or inconvenient. This also required for
proper ventiliation.
Ideally, the Power
2
should be placed in close proximity to
the NHT Controller or surround processor. Minimizing
cable lengths reduces the chance of noise pickup.

Connections
Audio Connections
CAUTION: Before connecting anything make
sure the Power2 and all your other electronic
components are turned off.
Use the highest quality connectors you can afford. Keep
all your wires as short as possible and routed neatly to
minimize noise problems.
To minimize noise problems, try to segregate wires by
function, and separate them by the maximum practical
distance. Where audio wires and AC power cords inter-
sect, cross them at right angles.
The Power2 has two inputs. Its best before you set up
your system to decide what channels are used for what
speakers.
7 Speaker Connections
CAUTION: Before connecting anything make
sure the Power2 and all your other electronic
components are turned off to reduce the risk of
electrical shock or damage to the components.
The minimum gauge speaker wire recommended for
runs of 20 feet or less is 14 gauge. Heavier special
purpose cable can be used for longer runs. For best
results, use equal length runs of cable for the left and
right speakers (or for the left, center and right speakers).
CAUTION: Using speaker wire of less than 14
gauge can cause the speaker wire to heat up,
possibly melting the insulation and causing a
risk of fire or damage to the unit. To minimize risk of dam-
age or fire, make sure the insulation on your wires is not
damaged, and never allow exposed wire to contact other
wires, or the chassis of the amp.
