this way, jitter is completely eliminated—and the integrity of the original

musical signal is restored.

• DC Phase Linearizer (DCPL). Interaction between traditional amplifiers and

real-world loudspeakers cause significant departure from phase linearity at

frequencies below 30 or 50 Hz. These shifts have a subtle effect, creating

warmer and more accessible bass. Sony's DC Phase Linearizer gives you

several control positions, including Off, enabling you to adjust low-frequency

phase shift and restore this effect.

• Complementary Pulse Length Modulation (C-PLM). Previous digital

amplifiers have used a 1-bit technology called Pulse Width Modulation or

PWM. Those digital amplifiers varied the width of pulses. Unfortunately,

PWM tends to expose the signal to second-order harmonic distortion. C-PLM

effectively controls the distortion, maintaining the integrity of the musical

signal.

• Synchronous Time Accuracy Controller (S-TACT). Because C-PLM

conversion expresses the music in a different digital form, the signal requires

another round of correction for time-base errors. Synchronous Time

Accuracy Controller (S-TACT), originally developed for Sony's SCD-1 Super

Audio CD player, effectively clears pulse generator jitter by referencing the

output directly to the master clock. This establishes extremely accurate pulse

timing for amazingly low distortion.

• Pulse Height Volume Control. Most digital volume controls work by Digital

Signal Processing, an approach that sacrifices detail in the least significant

bit. Sony's Pulse Height Volume control adjusts the 1-bit C-PLM stream by

adjusting the regulator that supplies voltage to the power pulse generator.

Because this method does not modify or reshape the original digital samples,

there's no loss of information, no loss of detail. Sound quality is maintained

from very low volume settings all the way to maximum.

Sony's S-Master Pro design delivers a host of benefits.

• Simplicity. Digital signals remain in the digital domain until the last possible

moment. The purity and clarity of digital source material is maintained.

• Low heat generation. With S-Master Pro, the output MOS FET transistors

simply switch between fully On and fully Off states. The transistors operate at

nearly maximum thermal efficiency. This has a profound impact on the

physical design of the power amplifier.

o The amps can be far more compact, because the heat sinks take

up far less space. This is a major consideration when you have

seven amplifiers, each putting out 170 watts per channel (all

channels driven, 8 ohms, 20 to 20,000 Hz, at 0.15% THD).
