NAD Introduces High Performance Stereo Receiver With Multi-Zone Capabilities

New C720BEE Demonstrates NAD's Continued Commitment to Two-channel Audio for Custom Installation Applications

NAD has introduced its latest stereo receiver, the C720BEE, combining the same amplifier design from the award winning C320BEE Stereo Integrated amplifier with an RDS AM/FM tuner, and Multi-source Zone 2 capabilities.

Lenbrook offers the NAD C720BEE stereo receiver

Like many of NAD's most innovative products, the 720BEE comes from the creative mind of Bjorn Erik Edvardsen, Director of Advanced Developments. Soft Clipping, Power Envelope, and PowerDrive are just a few examples of Erik's engineering skill. The BEE moniker for NAD's latest receiver recognizes Erik's contribution to the marquee, now in its 32nd year.

NAD has long been recognized for their stance in full-disclosure ratings for their amplifiers, which guarantees minimum continuous power output of the C720BEE's generous 50 watts (x2) under the "worst case" loading of 4 Ohms and 20Hz to 20kHz with both channels driven simultaneously.

The C720BEE also benefits from NAD's proprietary PowerDrive topology that enables an amplifier to effectively handle musical dynamics and difficult speaker loads. Most impressive are the C720BEE's dynamic capabilities; up to 220 Watts into 2 ohms and up to 50 amps peak current capability.

PowerDrive allows the C720BEE to deliver tremendous dynamic power with low impedance drive capability, seemingly contradictory traits in a single amplifier. This is the result of a multistage power supply with a very sophisticated analogue computer that determines whether to switch to a high voltage or a high current rail depending on the specific operating condition. This optimization is fully automatic and utterly transparent during operation for a sound that is far larger and more powerful than its continuous power rating would suggest.

The C720BEE also incorporates NAD's acclaimed switchable "Soft Clipping" circuit, which significantly reduces the risk of damage to loudspeakers due to prolonged high power operation.

Flexibility is another NAD strong point. The C720BEE has 7 line inputs and the pre-amplifier section can be separated from the power amplifier for easy upgrades or adding ancillary equipment. Thus the C720BEE can be expanded to meet future system needs.

The accuracy of the tone controls has been improved over the C720BEE's predecessor the C740, by increasing their boost/cut range by 1.5dB. The tone controls only work at the frequency extremes leaving the critical mid-band essentially unaltered. The tone control circuits can be completely bypassed by using the tone defeat switch.

The C720BEE feature many circuit refinements in the power amp section resulting in dramatically reduced dynamic intermodulation distortion. In measurement terms, both static and dynamic IM distortion is reduced between 10dB to 20dB. (to reach -90dB to - 100dB.) In audible terms this improves definition, purity and resolution, which results in remarkable imaging.

The C720BEE is fully remote controlled and comes supplied with the NAD SR5 system remote control. The remote control will also operate other NAD products such as CD players. We also include a small Zone 2 remote that allows input switching from a remote zone when used with an IR extender eye. A second zone can be configured by using the switchable Speakers B option.

For remote on/off switching of ancillary components in a system, such as power amplifiers or active speakers, the C720BEE is equipped with a 12V-trigger system. When switching the amplifier on, the 12V- trigger output is also activated, which when connected to a device with a 12Vtrigger input will switch on the remote device. Besides the 12V-trigger, the C720BEE also has an AC switched outlet so you can easily switch your entire system on or off with the remote control or from the front panel.

The NAD C720BEE Receiver is available from May 2005 and will retail at a suggested price of £399.95 including VAT. It comes in either a Titanium or a Grey Finish.

New NAD/PSB Two Channel Surround System Introduced

Affordable Combination Saves Space and Offers Sub-Woofer Option

Lenbrook UK has announced the introduction of a new two-channel surround system comprising the L53 DVD/CD Receiver and PSB B25 audio/video monitor speakers. The complete system can be bought from selected Lenbrook retailers for around £650 complete.

The concept behind the system is to offer a simple affordable solution to the many consumers who don't want the typical, often unnecessary Ð and even more often, poor quality - speaker array offered by so many high street brands. The L53/B25 combination saves space and yet delivers an enveloping surround sound sensation from just two speakers, whilst giving the option of a subwoofer for those who want even more bass depth.

The versatile and unobtrusive PSB B25s, which can be placed on shelves, mounted on walls, or on matching stands, are supremely easy to accommodate. Like the acclaimed PSB Image towers and centre-channels, they all use the same optimized 1-inch aluminium-dome tweeter, combined with one of two sizes of a new rubber-surround woofer and two modular baffle elements that come together in various ways. The B25 woofer size (6.5") allows this speaker to produce full-weight sound down to a satisfying point both for musical instruments and cinematic effects.

The NAD/PSB L53 Surround System is available now at a suggested retail price of around £650 complete. The L53 can be bought on its own for around £400 and the B25s for around £250 per pair. All prices include VAT. There is a range of affordable PSB sub-woofers to complement the set-up if so required.
