■AMPLIFIER FEATURES
130 WATTS MINIMUM OF CONTINUOUS RMS POWER
to each of the 7channels into 8 Ω , from 20 Hz to 20 kHz with no more than 0.05%THD (FTC rating)–clean high-current amplification provides incredible dynamic range for seamless reproduction of even the most demanding cinema soundtracks, as well as animatedly rich music at any volume level.
7.1-CHANNELAMPLIFIER–the first receiver to achieve this feat in one chassis–the TX-DS989 provides unparalleled power and clarity to all 7.1-channels for a room-filling sound experience seconds to none.
LUCASFILM THX® ULTRA CERTIFIED–in addition to the amazing ability to drive 7.1 channels, the TX-DS989 also boasts the distinction of carrying the exclusive THX Ultra badge of approval–assurance that this receiver passed (and often exceeds) THX's numerous requirements in such areas as frequency response, distortion, power output, and stability.
192kHz/24-BIT D/A CONVERTERS FOR ALL CHANNELS– the first receiver in the industry to utilize these powerful converters for all seven channels–theTX-DS989's DACs not only boast a dynamic range of 120dB, they also process more information faster and are virtually resistant to clock jitter, to ensure the best performance possible from DVD-Audio and other upcoming formats, while also producing cleaner, clearer sound form DVDs and CDs.
WIDE RANGE AMPLIFIER TECHNOLOGY(WRAT) WRAT virtually eliminates the adverse effects of counter- electromotive force by: 1) applying an uncommonly low amount of NFB (negative feed-back), 2) using carefully selected, high-tolerance, wide range parts in all critical sections, and 3) incorporating innovative circuit topology based upon decades of high-endamplifier-designexperience–the final result is a flat response beyond 100kHz, making the TX-DS989 ideal for such high-resolution formats as DVD-Audio and Super Audio CD, and other upcoming digital formats.
■FLEXBILITY FEATURES
FUTURE-PROOF INTERFACE ARCHITECTURE–a versatile RS232 port allows the TX-DS989's powerful 4Mbit Flash Memory to be directly computer accessed for installing such future upgrades as new DSP algorithms, new surround formats/parameters, and other types of processing updates.
ZONE 2 MULTIROOM/MULTISOURCE CAPABILITY–a full set of line outs for audio, composite video, and S-video, allows for set-up of an additional system in another room–connect an optional infrared eye in Zone 2, and complete second-room control can be achieved with such A/V distribution control systems as Xantech® , Niles® , to name but a few.

THX Ultra
Before any home theatre component can be THX Ultra certified, it must pass a rigorous series of quality and performance tests. Only then can a product feature the THX Ultra logo, which is your guarantee that the Home Theatre products you purchase will give you superb performance for many years to come. THX Ultra requirements define hundreds of parameters, including power amplifier performance, and pre-amplifier performance and operation for both digital and analog domains. THX Ultra receivers also features proprietary THX technologies (e.g. THX Mode, see page 38) which accurately translate film soundtracks for home theater playback.
