PROGRESSIVE AUDIO CD2 PLAYER

Drive CDPro2

Drive is supported on a 80 mm high rack, milled fully out of aluminum, including the lid drive unit in a decoupled manner.

All housing parts are made of aluminum, which has the certification for the aircraft, and are manufactured in Germany . In this way we achieve a perfect standard of quality in material composition and color uniformity.

PROGRESSIVE AUDIO CD2

Using the CD drive Pro 2 guarantees that absolutely all data on the CD will be read, no error correction is required.

Because data, which can not be read, are missing for the music signal and can not be corrected by the error correction.

The supply voltage of the CD2 relates from a specially developed switching power supply. Because of the perfect galvanic isolation no interfering pulses reach from the main power supply system into the player and no tact noises get back into the main power supply system.

PROGRESSIVE AUDIO CD2

The signal processing is digital / analog Balanced

The analog branch works with the same circuit design as the amplifiers A1 and A2, balanced in pure Class A operation

The composition is purely modular and therefore upgradeable

Investment protection through an optional USB interface, which also enables the play of Flac files of 192kHz 24-bit

Streaming is feasible at the highest level

PROGRESSIVE AUDIO – WORLD‘S NO 1 IN APPLYING SILICON CARBIDESEMI CONDUCTORS IN HiFi AMPLIFIER TECHNOLOGYIn 2009, after 2 years of development, Progressive Audio was successfull in the use of Silicon Carbide in amplifier technology for the first time.

Why Silicon Carbide is this eminent

Semi Conductors made of Silicon Carbide are 15 times faster than all FETand V-MOS Semi Conductors.

A milestone in processing of impulse, since music is impulse and not alone representation of a sinus.

Only the time-correlated processing of very high momentum fluxes allows a lifelike reproduction of music.

SILICON CARBIDE IN AMPLIFIER TECHNOLOGY

Thanks to the successful usage of Silicon Carbide, we at Progressive Audio are fastly

approaching our objective to reproduce music in its most natural way.

With the controlabillity of Silicon Carbide, we at Progressive Audio expand our unique

characteristic and make a huge step ahead to meet our objective to effortlessly drive

loudspeakers independent of their design.

CIRCUIT DESIGN AND TONAL CONSEQUENCES OF SILICON CARBIDE

The design of the amplifier is symmetrical on every level.

Every level works in pure A-mode until clipping.

Volume control is realized with a matrix of relays (consisting of rhodium-plated contacts) which operate 0.1% instrument shunts. Hereby you can accomplisha full-bodied representation and finely tuned dynamics of the acoustic patterneven at very low levels, which is without equal.

At low and also at high levels, independent of the impedance frequency responseof the loudspeaker.

CIRCUIT DESIGN AND TONAL CONSEQUENCES OF SILICON CARBIDE

The impression is always the same, even with very complex signals...

It seems as if every instrument had its own amplifier, the control is outstanding.

Control is one important prerequisite – another one is the ability to naturally fade out instruments.

This is achieved by an output circuit without negative feedback and a frequency range of 1 MHz

A popular nickname for our A1/A2 is Power Pump!

Wrong!

Radiation pattern

Correct!

FOR EXAMPLE

Surely you have ever wondered why in a 100 piece orchestra playing with full volume, you never have the impression of a high volume, although there is a sound pressure of 120 dB effortlessly produced.

But when listening music with high volume in your own 4 walls, you more often prefer to turn the volume down due to ear pain.

The reason is the time offset in the reproduction of high to low frequencies.

If the pulse is temporally offset, our highly sensitive pressure transducer, the human ear, feels that as an annoyance rather than a musical enjoyment.

THE LOGICAL CONSEQUENCE

Phase linear electronics and phase linear speakers require an interconnecting wiring , which with pulse proper reproduction, makes the smallest possible error.

THE LOGICAL CONSEQUENCE

Criteria for NF and speaker cables from Progressive Audio High purity copper with a residual oxygen content

of sensationally low 3PPM (which is nothing, that copper is so pure and soft that it

caused problems during drawing and manufacturing process,

which we were able to eliminate only with deep cooling)

Criteria for NF and speaker cables from Progressive Audio

This is for the purpose, that through the smallest OFFSET DC voltages, which are often subordinated to the useful signal, and through magnetized conductor material no phase shift due to eddy currents arise.

The structure, 1000 - 5000 individual cores, all isolated from each other, guarantee equal resistances for the deepest and the highest frequencies of 1HZ-500 Khz
