In terms of raw power, the HK 990 is the most muscular amplifi er ever to carry the

Harman Kardon ® name, more than capable of driving the most demanding loudspeaker loads without breaking a sweat. But the HK 990’s awesome power is nothing if not highly refi ned, extending beyond watts and amps. With a choice of discrete optical or digital inputs or an analog-only signal path, as well as fourth-generation Real-Time Linear

Smoothing (RLS IV), 2.2-channel EzSet/EQ room optimization, dual subwoofer outputs,

USB connectivity and an audiophile-quality phono preamp section, the HK 990 offers a combination of features you will fi nd irresistible. Others, of course, may simply hunger for all that power. We understand completely.

Features

Power

• 150W x 2 into 8 ohms, 20Hz – 20kHz, at <0.07% THD, with all channels driven simultaneously

• High-current (±100 amps), ultrawide-bandwidth (10Hz – 100kHz) amplifi er design

Connectivity

• Six analog stereo audio inputs

• Two analog recording outputs

• Four digital inputs (two optical and two coaxial)

• One USB input for playback of audio fi les stored on a PC

• Dual subwoofer outputs to connect up to two active subwoofers

• One coaxial digital output for recording

• Two real balanced inputs, using XLR connectors

• One HRS (high-resolution synchronization) link

• 2.2-Channel processor input allows the use of external audio processors

• Two high-quality phono inputs for connection of record players with an MM or MC cartridge

• 2.2 Preamp outputs allow the use of external power amplifi ers

• Remote control input and output

• Heavy-duty binding posts allow for the use of speaker cables up to 10mm 2

Ease of Use

• High Current Capability provides the instantaneous current necessary to precisely drive and control nearly any loudspeaker system

• Ultrawide-bandwidth amplifi er 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

• Dual-path technology allows for pure analog or pure digital audio processing within the same product

• 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

• The HRS link allows Harman Kardon CD players to lock themselves to the external clock of the amplifi er for a jitter-free connection, similar to having the CD playback inside the amplifi er

• Dual differential input stages with their own high-voltage supply, resulting in high gain and low noise

• Cascoded predriver stage considerably reduces high-frequency distortion, allowing crystal-clear high frequencies, free from any harsh sound

• Thermal Tracking Mechanism using ThermalTrak TM output stage transistors that include internal temperature sensors to bias the current of the output stage in real time

• Sophisticated electronic protection circuitry guards the amplifi er from short-circuiting or from damaged speakers and wires, without impairing sound quality, by using current-limiting or output relays

• DC servo to ensure that the DC level of the amplifi er output will stay within a contained limit at any condition

• Multiple protection circuits will switch the amplifi er off in case overcurrent, overvoltage, overtemperature or DC protection is detected

• Dual toroidal transformers and up to 16.000μF of supply fi ltering per channel will allow high channel separation and tight bass control, even with a low-impedance load

• Dual-line dot-matrix display

• Record out available in both digital and analog domains (two analog outputs and one coaxial digital output)

• Remote A/B speaker switching

• IR remote extension jacks for control of the amplifi er when placed in a cabinet

• Harman Kardon system remote for control of compatible Harman Kardon CD players and tuners
