C 725BEE Stereo Receiver

> P O S I T I O N I N G

The NAD C 725BEE is in a category of one; unique in both performance and capability. Most receivers available today are digital surround sound

AV Receivers. While these are appropriate for Home Theatre use, with very few exceptions they cannot match the performance of a good stereo amp when driving stereo speakers. The C 725BEE, by contrast, is an analogue design based entirely on our award winning C 325BEE Integrated

Amplifier. By combining all the most desirable features in a one box solution, we can offer the performance of separate high end components and the convenience of a receiver.

All this performance and convenience comes at a far more affordable price than separate components would cost.

Performance

This is a true BEE (Bjorn Erik Edvardsen) design with all his latest developments including:

PowerDrive, Distortion Canceling Circuit, BEE

Clamp and an all new and more highly refined circuit layout. Based on a high current toroidal transformer – the same type found on our own high end Masters Series – the C 725BEE can provide a healthy, ultra low distortion 50 watts of continuous power.

But more importantly, on a short term dynamic basis (which is the way music reproduction demands the power to be delivered) the

C 725BEE can provide as much as 200 watts depending on the characteristics of the loudspeaker being driven. If, for any reason, more power is asked for than the C 725BEE can provide the exclusive Soft Clipping circuit prevents the harsh grating sound of hard clipping distortion.

C 725BEE Stereo Receiver

> D E T A I L S

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 refinement that makes your music come to life!

Imagine a big 3 dimensional sound stage with each instrument clearly defined 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.

Additional convenience features include an IR remote commander, connections for a second set of speakers, and a highly informative 2 line vacuum fluorescent display. Audiophile features like multi-way speaker binding posts and gold plated input sockets all add to the performance and reliability of this fine instrument. There is even an output for adding a powered subwoofer!

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.

For those areas that support DAB broadcasts, the

C 725BEE is equipped with a special socket on the rear panel that accepts NAD’s 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.

Custom Installation

There is a line level Zone 2 output with independent source selection allowing you to add an amplifier in another location and listen to all your sources connected to the C 725BEE.

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.

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 certified compatible with Crestron, AMX and Savant system controllers. The inclusion of 12V trigger output gives additional flexibility and compatibility for custom installations.

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 identified 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 amplifier efficiency 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 flexibility 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.
