Analog Volume control.

The analog volume control is fully balanced with state of art R2R 4Q DAC as attenuator. To lower the noise as much as
possible the attenuator has an internal constant impedance of 5K where in many designs 10K, 20K or even 100K is used in
the attenuator.
The range of the attenuation is -120 to + 12dB in 0.5dB steps.
By pressing the center button on the remote the volume is muted to -120dB. It shows up as "MUTE" in the display marked
as RED as well.

Gain stages.

All gain stages are JFET folded cascode enabling true single gain stage technology followed by a high quality buffer. The
design of the gain stages is a carefully selected blend of JFET's and bipolar transistors to give optimum performance.
