     NAD  317 [1st unit]  stereo amplifier - charcoal grey :
     Description and features :
  • 2 x 80 Watts continuous power into 8 ohms
  • 2 x 250 Watts dynamic power into 2 ohms
  • Remote control capable
  • Building Block Concept: power amp is same as NAD Model 214
  • Pre-out / Main-in
  • All Discrete circuitry
  • Tone controls defeat switch
  • Bridgeable for mono 240 Watts into 8 ohms
  • Input switching through relays with Gold Plated contacts
  • Soft Clipping

   Since its introduction, the NAD Model 214 Power Amplifier has enjoyed a strong following and tremendous reputation throughout the world for its performance and reliability
   The latest addition to NAD's range of integrated amplifiers is the Model 317 which is very closely related to the Model 214. In fact, the entire Power amplifier inside the Model 317 is identical to that of the Model 214

   Flexibility : Flexibility is a traditional strong NAD point. The Model 317 has 6 line inputs (including 2 tape in/outputs with dubbing facility both ways). By removing the links between the Pre-out and Main-in sockets the preamplifier section can be separated from the power amplifier for easy upgrades (bi-amping, for instance) or adding ancillary equipment
   As the built-in power amp of the Model 317 is identical to that of the NAD Model 214 you can easily triple the output power to your speakers by adding a Model 214 to your system. Bridge both power amplifiers and you have increased the power of your system to 2 x 240 Watts continuous into 8 ohms. Thanks to this "Building Block Concept" your Model 317 doesn't need to be made redundant to upgrade

   Performance : Rather than using electronic switching between sources, the NAD engineers have opted for using relays as these will give better performance at this price level. To ensure long term reliability only relays with gold-plated contacts have been used. The input selector relays are located as closely as possible to the input sockets to minimise cross talk and interference
   As with the relays, all input and output sockets are gold plated to ensure reliable signal transfer. A generous power supply (the same massive Holmgrentrade; Toroidal transformer as the Model 214 is used) and over-rated output devices further lead to low noise and low distortion

   Integrated Amplifier : The overall high level of performance is achieved by using discrete circuitry only and high quality closetolerance components such as metal film resistors and polypropylene capacitors. As one would expect from any NAD amplifier, the Model 317 will drive loudspeakers with complex loads (such as low impedances) with great ease
   The Model 317 also incorporates NAD's acclaimed switchable "Soft Clipping" circuit which significantly reduces the risk of damage to loudspeakers due to prolonged high power operation
   Convenience, flexibility and, above all, performance, are the hallmarks of the NAD Model 317. Consistent with NAD's reputation the Model 317 is somewhat of a bargain when compared to amplifiers with similar performance
