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,

• 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
• 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
• 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
