Harman-Kardon HD 970 owner manual Introduction, Description and Features, Class, Laser

Introduction

Thank you for choosing Harman Kardon HD 970 CD player.

The HD 970 is an exceptionally well-engineered product that offers high performance and ease of use.

Along with conventional CD audio discs, the HD 970 is also compatible with MP3 data from CDs and most recordable CD formats.

We ask that you take a few minutes to read through this Owner’s Manual to familiarize your- self with the controls and functions. This brief investment of time will yield dividends in the form of years of listening pleasure.

If you have any questions about this product, its installation or operation, please contact your dealer, as they are your best source of local information.

Description and Features

Ever since its introduction in 1992, Harman Kardon RLS (Real-time Linear Smoothing) conversion technology has been hailed as an efficient, high performance means of transforming the, at that time 16-bit, digital signal from CD to high quality analog. The short RLS signal path resulted in hitherto unknown clarity and detail, in combination with awesome dynamic resolution of the critical bass frequen- cies.

RLS-II was a natural, yet radical evolution of the original RLS concept.

Since then, dramatic progress has been made in Digital Signal Processing, allowing the integra- tion of DSP's in a standalone CD Player and the implementation of a very powerful algorithm in the digital domain: the birth of the RLS-III.

Using theoretical roots of the RLS, RLS-III has set new standards for dynamic range and shifted noise to an absolute non-audible frequency range with very high jitter rejection. The result is an astonishing common signal format of 24 bits at a sampling frequency of 384 kHz.

This 24 bits/384 kHz signal format allows Harman Kardon engineers to take a minimalist approach to the subsequent analog filtering, without paying any penalty in the form of the aliasing errors and artifacts.

Harman Kardon's analog processing legacy has been expressed to its optimal level in the output stage of the HD 970 with High Definition, Wide Bandwidth and Low Feedback circuitry in a pure Class A configuration, using only high grade components.

A unique feature of the HD 970 is that it allows other source components to be played back using the high-grade audiophile digital-to-ana- log convertors inside the CD player. Especially source components using older and less power- ful convertors will benefit from this feature.

Important Note: The player will only output

2-channel PCM signals. Neither multi-channel Dolby Digital or DTS nor their 2-channel down- mix signals will be output.

■Asynchronous Digital Processing for Highest Possible Jitter Rejection based on a 32bit DSP
