150 watt, stereo-integrated amplifier
Mfg Model:
HK 990
As the most powerful stereo-integrated amplifier ever to carry the harman/kardon® name, the HK 990 captures listeners’ attention – and how could it not, with its expectation-defying 150 watts of power per channel. And even though the HK 990 may amaze some with its musical prowess, make no mistake: Its power is highly refined, and it can handle the most demanding loudspeaker loads with the greatest of ease.
SPECIFICATIONS
Superlative two-channel music reproduction is one of the toughest challenges for any audio component. In this regard, the HK 990 offers you a superb blend of irresistible features destined to win the affections of the most discerning of audiophiles. As the most powerful stereo-integrated amplifier ever to carry the Harman Kardon® name, the HK 990 captures listeners' attention - and how could it not, with its expectation-defying 150 watts of power per channel. And even though the HK 990 may amaze some with its musical prowess, make no mistake: Its power is highly refined, and it can handle the most demanding loudspeaker loads with the greatest of ease. As a complement to this muscularity, the HK 990 also boasts an impressive list of advanced performance features, such as fourth-generation Real-Time Linear Smoothing (RLS IV), EzSet/EQ for room optimization, dual subwoofer outputs and a high-current, ultra-wide bandwidth design for clear sound and more precise imaging. And that's only the beginning. In its quest to overachieve, the powerful HK 990 takes additional strides in the area of versatility, offering six analog stereo audio inputs and four digital inputs to ensure optimal compatibility with various signals.
Features
High-current capability provides the instantaneous current necessary to precisely drive and control nearly any loudspeaker system
Ultrawide-bandwidth amplifier design for improved transient accuracy and phase linearity
Low negative feedback for further improved dynamic accuracy
Use of discrete electronic circuitry to provide the highest performance level
EzSet/EQ room optimization for quick and accurate system setup, optimized for two channels and two subwoofers
Symmetric (balanced) XLR analog inputs offer lower noise levels and higher signal-to-noise performance
RLS IV digital-to-analog conversion technology, with dual conversion using two stereo AD1955 high-grade DACs
Dual differential input stages with their own high-voltage supply, resulting in high gain and low noise
