.:SA-1 The 2 Channel Audio Power Amplifier


With today's quality parts and the improvement of the original design, this amplifier will again set a new industry standard, just as the original did.
To extend the quality of this product as much as possible, several features has been built into the concept.

  • All transistors are matched to further reduce the distortion.

  • Only high current, high temperature low impedance capacitors are used. This current reservoir is made up from different sizes of capacitors in parallel, to create a supply as linear as possible for all frequencys.

  • A “clamp” is holding these capacitors, forcing them together to remove any internal movement of the electrolytic so that the well known “micro phonic” effect is avoided.

  • All AC and DC voltages are connected with 2x6mm copper rails to avoid any cables in the current path.

  • A new type of speaker terminals has been developed under the name “d’vise”. It is made from 16mm copper bolt and 2mm copper bracket to ensure that there are no impedance loss or “diode” junction between your speaker cable and the output transistors.

  • Fully protected with an intelligent protection circuit with no influence on the sound.

  • Balanced and singel-ended inputs.

  • Balanced bridgeable to 4 times the power.

.:PA-1 The 2 Channel Audio Pre Amplifier

Preliminary

The PA-1 preamplifier is a unit that matches the SA-1 in physical size

Standard features:

                          3 balanced and 3 single-ended (RCA) inputs
                          1 balanced and 1 single-ended output
                          1 rec output
                          Remote control
                          Digital potentiometer
                          Home Theatre input

DFC (dynamic feedback control)
A special feature never done in any sound reproduction equipment is a DFC (dynamic feedback control) concept.This concept has different feedback for different frequencies. With the remote control the value of the DFC can be adjusted while playing, changing the control of the low frequency and compensate for room problems.

Extra features:

Digital input
One of the inputs can be converted to Digital input.

The DAC is a 24bit 192 KHz up sampling with digital output.
When the DAC board is plugged in, the unit will sense this and change the text in the display.

Phono MM/MC
One of the inputs can be converted to Phono (RIAA) input.

When the Phono input is plugged in, the PA-1 will go into a menu mode making it possible to select between MM or MC cartridge. In the MC mode the loading and/or the feedback can be adjusted with the remote control while playing music, making it possible to fine tune the Phono input.

This adjustment can be done at any time by entering the menu mode of the preamplifier.
