• Two 150-watt-per-channel amplifiers with high-current capability

  Two 150-watt-per-channel amplifiers with high-current capability

  By leveraging high-current capability (HCC), the HK 990’s150-watt-per-channel, integrated amplifier maintains the instantaneous current required to drive nearly any loudspeaker system, delivering dynamic peaks, tight bass and superb transient response at any volume level.

• Real-Time Linear Smoothing

  Real-Time Linear Smoothing

  Fourth-generation Real-Time Linear Smoothing (RLS IV) minimizes interference during digital-to-analog (DAC) conversion through the use of two high-grade, stereo Analog Devices (AD) 1955 DAC chips – one per channel. The result is richly detailed sound, a noise level that remains locked in the non-audible frequency range and a higher level of jitter rejection.

• EzSet/EQ auto calibration

  EzSet/EQ auto calibration

  To tailor the HK 990’s loudspeaker outputs to match playback volume levels, balance and timing for your specific room conditions automatically, the EzSet/EQ auto-calibration process features an easy-to-follow menu display and a plug-in calibration microphone.

• High-resolution synchronization for smooth system connection

  High-resolution synchronization for smooth system connection

  A special high-resolution synchronization (HRS) link enables jitter-free clock synchronization and data transmission between HRS-link-enabled devices like the HK 990 power amplifier and a suitably equipped Harmon Kardon® CD player. The elimination of at least one stage of digital-to-analog conversion at the CD player’s output, and analog-to-digital conversion at the amplifier’s input, results in clear, enveloping sound. The HRS link is simple to set up using the supplied synchronization cable.

• Minimal signal disruption

  Minimal signal disruption

  The HK 990’s XLR inputs can receive fully balanced connections that reject both external noise and internal crosstalk from adjacent signal cables. Even better, XLR inputs accommodate increased signal levels for improved signal-to-noise performance.

• Flexible connectivity

  Flexible connectivity

  The HK 990 features connections for up to six analog audio devices and two analog recorders. In addition, a total of four digital inputs and one coaxial digital output ensure that the HK 990 will stay compatible with high-performance products of the future.

• Dual phono inputs

  Dual phono inputs

  Two, high-quality phono inputs enable connection to record players – fitted with either an MM (moving magnet) or an MC (moving coil) cartridge – that will breathe new life into your collection of vinyl LPs and 45s. Now you can hear all of those classic albums and singles in the best audio quality.

• Optimized, dual subwoofer outputs

  Optimized, dual subwoofer outputs

  Two dedicated outputs enable smooth low-frequency playback from external subwoofers with a dramatically increased bass response. And built-in EzSet/EQ II technology calibrates subwoofer playback to match your room’s conditions, providing optimized audio no matter where the system is placed.

• Heavy-duty, binding-post speaker connectors

  Heavy-duty, binding-post speaker connectors

  By accepting banana plugs, spade connectors or bare wire, the HK 990’s binding-post connectors provide secure links for your speaker cables. Color-coding reduces errors when you’re hooking up your speakers to the appropriate channel amplifiers.

• Dual analog and digital inputs

  Dual analog and digital inputs

  By leveraging dual-path technology, the HK 990 lets you decide whether to run a pure analog input directly into the amplifier stages or use digital inputs through the amplifier’s digital signal processing (DSP).

• Remote control and IR extension

  Remote control and IR extension

  Along with masterfully controlling your HK 990, the IR (infrared) remote control is also designed to operate any compatible Harman Kardon CD player, such as the HD 990. There’s even an IR remote extension jack so that you can program your power amplifier remotely.

• Harman Kardon sound: A legacy of achievement

  Harman Kardon sound: A legacy of achievement

  Exemplifying the balance among high style, modern design and audio ingenuity, the HK 990 two-channel amplifier fully embodies the spirit of Harman Kardon innovation, a legacy that discerning audio enthusiasts have revered for almost 60 years. Harman Kardon engineers have consistently advanced the science of sound, developing products that are dedicated to quality, durability and, most importantly, generating rave reviews from audiophiles.
