The S 170i is squarely focused on the individual who prizes sonic performance above all else, and appreciates the simplicity of the NAD approach. While you can fi nd less expensive processors, and processors with a longer punch list of “features”, the S 170i offers a level of performance for money that is unmatched. Whether used as an analogue preamp in Stereo Bypass mode, or used to decode the

latest formats from Dolby, DTS, and THX, the S 170i brings a purity and dynamic realism to every performance. This goes beyond specs or features and speaks to the real reason for spending this much money on a Hi-Fi:

to create an experience that transports the listener/viewer to that special place created by the recording artist. Indeed, it is this ability to “make the machine disappear” that separates the great products from the merely good products. The S 170i is a great product.

Features

The original S 170 was the fi rst THX EX processor to reach the market nearly two years ago, and it still remains the benchmark for sonic performance in this price category. With the development of THX Ultra 2, DTS ES and Neo:6, and Dolby EX and ProLogic II it is logical that NAD would update the S 170 to include these new decoding formats. We are pleased to introduce the S 170i, offering all the latest decoding formats while maintaining the same elegant simplicity, style, and performance of the original.

Signifi cantly, in these days of rapid digital format changes, the S 170i features a fully upgradeable digital processor on a separate plug-in circuit board. In fact owners of the S170 can have their unit upgraded to the “i” version for

a fraction of the cost of purchasing a new unit, proving the value of this design concept. All DSP processing and operating system “intelligence” is located on a plug-in module, making major upgrades a fairly simple process. Minor upgrades are offered free of charge and can be implemented via download from a PC using the RS-232 port located on the rear panel.

The modular processor dictates the use of a specially engineered, ultra-low-noise switch mode power supply, so that the S 170i achieves supply voltages of unexcelled stability and purity that remain totally independent despite varying demands on all eight channels, or even the requirements of future digital upgrades.

The bass management circuit of the S 170i offers tremendous fl exibility, while still meeting all the Dolby and THX mandates for bass redirection and Low Frequency Effects (LFE) channel management. The crossover frequency can be adjusted in 10Hz increments from 40Hz to 200Hz (except in THX mode where 80Hz is specifi ed), and individual channels can have their level tweaked in 0.5dB increments allowing much fi ner adjustment than that offered by most receivers and processors. Uniquely, the S 170i uses both digital and analogue fi lter sections for a superior electronic crossover characteristic.

Despite its deceptively simple appearance, the S 170i is also fully equipped to serve as a very able master
