This ultra low noise and distortion fountain of
power, gives music an effortless unforced quality.
The smallest details in your recordings now emerge.
The timbre of each instrument and rhythm of the
entire ensemble is now clearly revealed. This all
adds up to a level of re nement that makes your
music come to life!
Imagine a big 3 dimensional sound stage with each
instrument clearly de ned in its own space. It is
now so easy to hear all the details in your music
that listener fatigue is a thing of the past.
The highly sensitive FM tuner offers audio
performance that is as good or better than any FM
broadcast ensuring the best possible sound quality
for FM stations. RDS is also supported giving text
information about the station and songs being played
depending on the data sent by the FM station. AM is
also supported with the best possible quality from
this older but still popular broadcast technology.
All input switching is accomplished using sealed
reed relays. While these cost more than the usual
CMOS type switch used by lesser receivers, the very
low resistance of the relay keeps noise at the lowest
possible levels. Precision audio grade capacitors
are used in all critical circuit locations adding both
performance and reliability.
Features
In addition to the seven high level inputs on the
rear panel there is a front panel mini-jack for quick and easy hook up of a portable music player.
Additional convenience features include an IR remote
commander, connections for a second set of speakers,
and a highly informative 2 line vacuum uorescent
display. Audiophile features like multi-way speaker
binding posts and gold plated input sockets all
add to the performance and reliability of this ne
instrument. There is even an output for adding a
powered subwoofer!
For those areas that support DAB broadcasts, the
C 725BEE is equipped with a special socket on the
rear panel that accepts NADs optional DB 1 DAB
module which adds DAB reception. Just plug it in
and the C 725BEE operating software recognizes the
DB 1 module and makes a seamless integration.
If you are a vinyl LP enthusiast we offer a choice of
two optional outboard Phono Preamps, the PP 2 and
the PP 3. Both offer superb performance for both
MM and low output MC cartridge types. The PP 3
adds USB output to allow transfer of your LPs to the
HDD of your Personal Computer.
Custom Installation
There is a line level Zone 2 output with
independent source selection allowing you to
add an ampli er in another location and listen
to all your sources connected to the C 725BEE.
A separate remote commander is included to control
the C 725BEE from the remote location using independent IR codes. The IR input and output
sockets on the rear panel make it easy to attach any
of the many IR repeaters on the market today. The
C 725BEE also sports an RS-232 port and is certi ed
compatible with Crestron, AMX and Savant system
controllers. The inclusion of 12V trigger input and
output gives additional exibility and compatibility
for custom installations. A detachable AC cord also
speeds the installation process.
Green Features
NAD has responded quickly and responsibly to the
new awareness of environmental damage caused by
human activity. The C 725BEE is manufactured without
the heavy metals that have been identi ed as harmful
to the environment and manufacturing processes
meet the latest stringent international standards.
Power consumption during standby mode is less than
1 watt and PowerDrive technology improves ampli er
ef ciency during playback.
Value
As mentioned at the outset there is no other product
on the market today that offers the combination of
performance, convenience and exibility provided
by the C 725BEE. To amass a separate component
system that matches the overall performance of the
C 725BEE would cost considerably more and would
still lack the convenience of an all-in-one receiver.
