Like previous offerings from this company, this model has tone controls for bass and treble unlike previous offerings from this company, it also has a tone defeat switch. The damping factor into 8 ohms is said to be 120. S/N ratio is given as -80 dB for phono and -90 dB for line level inputs, both at rated output power. Sensitivities are said to be 150mV/43kohms for line level inputs and 2.5mV/47 kohms 125 pF for Phono MM input, which is said to overload at 100 mV. Frequency response is quoted as "0.5-100.000 Hz -3dB", and half power bandwidth into 8 ohms is said to be "<10-100.000 Hz". The manufacturer claims "instantaneous current capability" at +/- 40 Amps, however, without any statement under which conditions (how long is instantaneous?). It is rated at 40/60W into 8/4 ohms at THD figures of 0.09/0,3%, with dynamic power (as per IHF standards, 1 kHz bursts) ratings of 70/100/135W into 8/4/2 ohms. It's a bipolar design, well in the economy class though far from being the cheapest around, and with certain audiophile pretensions. Its physical dimensions are modest, 443x91x359 mm (WxHxD), while its mass is moderate at 6.4 kg (14 lbs).
Harman kardon 630 receiver specs code#
That said, let's get down to business, and the first item on our agenda is H/K's smallest integrated amp offering, code named, very mystically, 630. I think we all have our "sweet" companies, and H/K is mine, though it is not alone. That is why I admire them on the one, and criticize them so strongly on the other hand. I have to say it, just in case somebody didn't notice - I greatly admire and freely admit to being very strongly influenced by this company's philosophy and technical solutions. To this very day, the company is majority owned and managed by Dr Sydney Harman, a man who deserves the epithet of being quite unique in the audio world. Also, the company has grown to the point of being the owner of many audio companies throughout the world, such as JBL, Infinity, Madrigal, Mark Levinson, Proceed, Studer, AKG, Becker, etc. In the seventies, this company enrolled the services of one of the legends, and perhaps THE legend of amplifier design, Dr Matti Otala, whose work is embedded in modern amplifier design. In 1953, H/K invented the receiver, and from its early days, pioneered the philosophy of wide bandwidth and low feedback design. It belongs to a very select circle of what could be called "The Audio Industry Founding Fathers" group of companies, together with other greats, such as Marantz, Fisher, JBL, Klipsch, Altec and so forth. Harman/Kardon is a company founded by Dr Sydney Harman and the late Bernard Kardon, way back in the early fifties.
