What else to know about the Krell Studio?

The Studio, like the MD-20 has the black-grey-black-grey-black front panel, with vertical rows of red LEDs at the edges. the left row indicates sampling frequency and emphasis, locking when the DAC receives a signal. The right row indicates which of the four inputs (AT&T, TOSlink, RCA coax, AES/EBU) you've selected. Inbetween are a source/monitor switch and LED indicators – the Studio will feed a digital tape deck – phase inversion selector with LED confirmation, and a button to select the inputs. The selection process is one which scrolls from 1-4. Socketry at the back is provided for all four types of digital input, single-ended and balanced analogue output and optical or coaxial tape output. Inside, it's like enrolling at a military academy. Everything is so neat and tidy that you assume Dan D'Agostino is a Virgo with Virgo ascending. Krell wrote the software for the logic chips which control data recovery and clock synchronization. Two Motorola DSP-56001 chips are used, one per channel, producing a full 24-bit digital word for the DACs; user-replaceable EEPROMs contain the software, so upgrades to accommodate future algorithms won't require returning the unit to the factory. Each channel uses two 20-bit DACs operated in push-pull configuration. With 24-bit input through 20-bit DACs the detail resolution is improved substantially. The push-pull configuration eliminates zero-crossing distortion. The DACs' output is connected directly to the analogue output stages; there are no capacitors in the signal path and servo amplifiers ensure that no DC reaches the main outputs. The analogue section employs output amplifiers based on those used in Krell pre-amps: high bias, complementary Class A designs. \- Home Theater Review.

Brief History of McIntosh

Long mapped-to Binghamton New York – the current headquarters and manufacturing center for Krell Labs – not many people know the brand was originally launched outside of the Nation’s Capital in Silver Spring Maryland, in 1949. In 1956, the brand built their original facility in New York, according to the official brand website.
