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 . > D E T A I L S > F E A T U R E S Performance This is a true BEE ( Bjorn Erik Edvardsen ) design with all his latest developments including : • 50Wx2ContinuousPowerinto8ohms • Headphonessocket PowerDrive , Distortion Canceling Circuit , BEE • 102W , 148W , 205W , IHFDynamic • RelayInputSwitching Clamp and an all new and more highly refined powerinto8,4and2ohms , respectively • ToroidalPowertransformer circuit layout .

This all binding posts and gold plated input sockets all the heavy metals that have been identified as harmful adds up to a level of refinement that makes your add to the performance and reliability of this fine to the environment and manufacturing processes music come to life ! instrument . There is even an output for adding a meet the latest stringent international standards . powered subwoofer ! Power consumption during standby mode is less than Imagine a big 3 dimensional sound stage with each 1 watt and PowerDrive technology improves amplifier instrument clearly defined in its own space . It is For those areas that support DAB broadcasts , the efficiency during playback . now so easy to hear all the details in your music C 725BEE is equipped with a special socket on the that ‘ listener fatigue ’ is a thing of the past . rear panel that accepts NAD’s optional DB 1 DAB module which adds DAB reception . Just plug it in Value The highly sensitive FM tuner offers audio and the C 725BEE operating software recognizes the performance that is as good or better than any FM As mentioned at the outset there is no other product DB 1 module and makes a seamless integration . broadcast ensuring the best possible sound quality on the market today that offers the combination of for FM stations . RDS is also supported giving text performance , convenience and flexibility provided Custom Installation information about the station and songs being played by the C 725BEE . To amass a separate component There is a line level Zone 2 output with depending on the data sent by the FM station . AM is system that matches the overall performance of the independent source selection allowing you to also supported with the best possible quality from C 725BEE would cost considerably more and would add an amplifier in another location and listen this older but still popular broadcast technology . still lack the convenience of an all - in - one receiver . 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 A separate remote commander is included to control CMOS type switch used by lesser receivers , the very the C 725BEE from the remote location using low resistance of the relay keeps noise at the lowest independent IR codes . The IR input and output possible levels . Precision audio grade capacitors sockets on the rear panel make it easy to attach any are used in all critical circuit locations adding both of the many IR repeaters on the market today . The performance and reliability . C 725BEE also sports an RS - 232 port and is certified compatible with Crestron , AMX and Savant system Features controllers . The inclusion of 12V trigger output gives In addition to the seven high level inputs on the additional flexibility and compatibility for custom rear panel there is a front panel mini - jack for installations . quick and easy hook up of a portable music player . > R E A R L I N E D R A W I N G
