From NAD, 2001:

After so many illustrious and acclaimed predecessors, we are proud to up the stakes in integrated amplifiers yet again by introducing the all new C370. In the best NAD tradition, it offers a powerful blend of performance, flexibility and ease of use at a modest price.

Features:

The C370 is fully remote controlled and comes supplied with the NAD C Series system remote control. Because the C370 has NAD Link, the remote control will also operate many other NAD products such as CD players, tuners, and cassette decks.

Flexibility is another strong point. The C370 has 7 line inputs (including 2 tape in/outputs with dubbing facility) and the pre-amplifier section can be separated from the power amplifier for easy system upgrades or adding ancillary equipment. The C370 sports 2 preamp outputs, and one of them is variable from 0dB to -12dB. Many systems benefit from the use of multiple power amplifiers for "Bi-Amping" (using separate power amplifiers to drive the bass and treble section of a loudspeaker) but not all power amplifiers are identical in gain (amplification factor). With the variable Pre-out level control, differences in gain between the C370's own power amplifier section and an external power amplifier can be dialed out precisely. Two pairs of speakers can be connected and individually switched on or off (either via remote control or front panel.

Because the built-in power amp of the C370 is identical to that of the NAD Model C270, you can easily nearly triple the output power to your speakers by adding a C270 to your system. Bridge both power amplifiers and you have increased the power of your system to 2 x 300 Watts Continuous Power into 8 ohms. Thanks to this "Building Block Concept" your C370 need never become obsolete as you make system improvements.

For remote on/off switching of ancillary components in a system, such as power amplifiers or active speakers, the C370 is equipped with a 12V trigger system. When switching the amplifier on, the 12V trigger output is also activated which in turn can activate a 12V trigger input and switch on the remote devices, such as a C270 power amplifier, for example. Besides the 12V trigger, the C370 also has an AC switched outlet so you can easily switch your entire system on or off with the remote control or on the front panel.

It is fashionable to omit tone controls these days, but provided that the tone controls are properly designed, they can be really useful tools in making improvements in overall sound. The C370 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 C370 also incorporates NAD's acclaimed switchable "Soft Clipping" circuit, which significantly reduces the risk of damage to loudspeakers due to prolonged high power operation.

Impedance Sensing Circuit (ISC):

The C370 also benefits from NAD's proprietary Impedance Sensing Circuit (ISC) topology, now well established and used in many NAD models including the highly reviewed C320 and C340.

The ISC topology allows the C370 to deliver maximum performance under virtually any circumstance, independent of the loudspeakers it is driving. The circuitry automatically recognises the impedance characteristics of the loud-speaker and will then adjust its power supply settings to best cope with that specific load. With ISC topology, the relationship of voltage to current is kept at an ideal proportion, eliminating the current limiting distortion common in lesser designs. This also gives it an unusual characteristic compared to traditional amplifiers when measuring its continuous output power; the RMS out- put power remains the same at 120 Watts with either an eight or a four ohms load.

We take exception to mindless "brochure power" specifications, which don't give a realistic indication of an amplifier's true capabilities. Instead, the ISC topology is a practical approach to enable an amplifier to easily deal with musical dynamics and difficult speaker loads. More meaningful in the real world are the C370's dynamic capabilities; up to 450 Watts into 2 ohms and up to 70 amps current capability into 1 ohm!

Other design features include relay input switching (located right behind the input sockets for short signal paths) and the large Toroidal transformer (less mechanical hum and stray magnetic field). The generous power supply and overspecified output devices further lead to low noise and low distortion for the entire amplifier. Like all the other input and output sockets, the Pre-out/ Main-in sockets are gold plated for long-term contact reliability. The headphone socket will drive virtually any non-electrostatic headphone.

This powerful amplifier, with its transparent detail and solid low-frequency "sock," is one of the best-sounding amplifiers available at any price. With great flexibility as well as superb performance, it is a convincing top of the line for NAD Classic Series integrated amplifiers.
