317Integrated Amplifier• 2 x 80 Watts continuous power into 8 ohms• 2 x 250 Watts dynamic power into 2 ohms• Remote control• Building Block Concept: power amp is NAD's Model 214• Pre-out / Main-in• All Discrete circuitry• Tone controls defeat switch• Bridgeable: 240 Watts into 8 ohms• Input switching through relays with Gold Plated contacts• Soft ClippingSince its introduction, the NAD Model 214 Power Amplifier has enjoyed a strong following andtremendous reputation throughout the world for its performance and reliability. The latest addition toNAD's range of integrated amplifiers is the Model 317 which is very closely related to the Model 214. Infact, the entire Power amplifier inside the Model 317 is identical to that of the Model 214.FlexibilityFlexibility is a traditional strong NAD point. The Model 317 has 6 line inputs (including 2 tape in/outputswith dubbing facility both ways). By removing the links between the Pre-out and Main-in sockets the pre-amplifier 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 NADModel 214 you can easily triple the output power to your speakers by adding a Model 214 to yoursystem. Bridge both power amplifiers and you have increased the power of your system to 2 x 240 Wattscontinuous into 8 ohms. Thanks to this "Building Block Concept" your Model 317 doesn't need to bemade redundant to upgrade.PerformanceRather than using electronic switching between sources, the NAD engineers have opted for using relaysas these will give better performance at this price level. To ensure long term reliability only relays withgold-plated contacts have been used. The input selector relays are located as closely as possible to theinput sockets to minimise cross talk and interference. As with the relays, all input and output sockets aregold plated to ensure reliable signal transfer. A generous power supply (the same massive Holmgren™Toroidal transformer as the Model 214 is used) and over-rated output devices further lead to low noiseand low distortion.Integrated AmplifierThe overall high level of performance is achieved by using discrete circuitry only and high quality close-tolerance components such as metal film resistors and polypropylene capacitors. As one would expectfrom any NAD amplifier, the Model 317 will drive loudspeakers with complex loads (such as lowimpedances) with great ease. The Model 317 also incorporates NAD's acclaimed switchable "SoftClipping" circuit which significantly reduces the risk of damage to loudspeakers due to prolonged highpower operation. Apart from operating the Model 317, the remote control supplied with the 116 willalso operate many other NAD components. The NAD Link sockets provide for communication betweenthe other NAD components for complete control.Convenience, flexibility and, above all, performance, are the hallmarks of the NAD Model 317. Consistentwith NAD's reputation the Model 317 is somewhat of a bargain when compared to amplifiers with similarperformance.
