Harman/Kardon T403

 The T403 tuner was designed with a single goal in mind musically. The traditional attention that tuner designers give to a signal sensitivity cannot alone provide accurate musical reproduction.  Maitaining phase linearity throughout the early tuning stages is of criticalimportance because FM detectors transpose phase distortion of an incoming signal directly into harmonic and intermodulation distortion. Each operating section if the T403 is carefully designed and engineered to achieve optimum phase linearity.

 The T403 is sensitive and selective - and it is quiet. Noise, perhaps the most important element decreasing from tuner performance, falls to an inaudible -70 dB.

The unconventional"summing' meter used in the T403 combines signal-strength and center-of-channel tuning in a single, integrated roading that is more accurate and easier to usse than sseparate meters. Also unconventional are the features of the T403 - features usually found only on far moreexpensive tuners, adjustable muting, variable output level, detector output (for possible four channel use), and 75 Ω (including coaxial input), and 300 Ω antenna connections.

The T403 Sensitivity, selectivity extraordinary signal-to-noisse ratio, phase linearity and its superior sonic performance, make it an ideal companion for the A402 amplifier or for any high quality component.
