This M-eVOL volume circuit is based on a resistive array configuration and
employs a pair (for balanced circuitry) of highly-regarded BurrBrown PGA2310
volume control circuits which yield a very low inter-channel crosstalk in the

. As well, This circuit yields absolutely no measureable sonic degradation of the

P 5.3

audio signal regardless of the chosen volume setting.

All volume control circuits suffer from imperfect level matching between the left and
right channels, especially at low and high output levels. In simple terms this means
that the actual volume level is not identical for both channels at various setting

A high quality potentiometer-based volume circuit will typically have a variance of as
much as 1.5dB (red) between the left and right channels at the volume extremeties
as shown above. Our
consistent variance across the entire volume range of less that 0.05dB (blue); Signal
matching between channels is significantly more accurate over the entire volume
range as compared to a potentiometer type volume.

M-eVOL volume circuit maintains an extremely low and

Independent Inductive DC Filtering (I2DCf) is a unique type of DC voltage
regulation that Simaudio initially developed for the
components and has found its way into other
I2DCf uses one inductor, and is dedicated to each integrated circuit type component
(DAC, Op-Amp, etc.) in the audio circuit’s signal path. This unique voltage regulation
circuit achieves better noise filtering, substantially lower THD, improved channel
separation and lower crosstalk, a reduction in jitter for CD players, and more consis­tent DC voltage throughout the entire circuit as shown below. The end results are a
dramatically reduced noise floor, a dead quiet “black” background, a more realistic 3D
portrayal of the recording and perfect level matching between channels.

Without the blocking capacitors at the amplifier’s input, sound quality is improved as
the phase-shift caused by these capacitors is eliminated. Frequency response in
the bass region approaches 0Hz. As well, by removing all capacitors from the direct
audio signal path, ultimate soundstage focus is attained with less “smear’ or “blur”.

The frequency response curve in top figure is virtually flat throughout, and beyond,
the entire audible range as a result of the

MOON amplifiers. Conversely, the frequency response curve of a traditional

our
AC-Coupled amplifier design is far from perfect, as seen in the bottom figure; both low
and high frequencies in the audible range are noticeably diminished.

between a double-bass and an electric

bass in a heart-beat.

A power supply transformer with a tight regulation (low) factor assures that
power into more difficult speaker loads will be delivered closer to the theoretical
ideal. These transformers are significantly more expensive, but are the only way to
assure stability and consequently excellent sound quality under all conditions.

The three response curves in figure 3 demonstrate (i) a theoretically perfect transform
er regulation factor of 0% (green), whereby voltage remains stable regardless of the
current draw, (ii) a remarkably low regulation factor of 3% (black), found in

amplifier, where the voltage drops very slightly as the current draw increases

and (iii) a typical regulation factor of 10% (red), whereby, as the current draw increas­es, power supply voltage drops significantly, as found in most competing amplifier
designs.
