Audio amplifier SE-R1

Sets a new high performance standard for digital amplifiers by employing state-of-the-art components and innovative technologies. JENO Engine (Jitter Elimination and Noise-shaping Optimization) Jitter is a major cause of distortion in digital systems, and is caused by mis-timing in the master clocks used in digital-to-analogue conversion. To eliminate the degradation of sound caused by jitter, Technics has developed an original jitter reduction circuit, comprising a clock generator in the noise-shaping system to reduce jitter in the low-frequency range and a high-precision sample rate converter for suppressing jitter in the high-frequency range. Thus it reduces jitter in an ideal way over the entire frequency range. This works with a newly-developed and original high-precision PWM (Pulse Width Modulation) conversion circuit, optimising the noise-shaping speed, the degree and requantisation number, and the PWM gradation, in order to convert high-resolution signals to PWM without causing any damage to the dynamic range. These new technologies enable new Technics digital amplifier designs to reproduce the natural and delicate nuances of music. GaN-FET Driver (High Speed and Low Impedance Power devices) In the speaker-driving section of the amplifier, Technics has employed a high-speed GaN (gallium nitride) FET driver device with super-low resistance. This enables the construction of a high-power amp using a single push-pull configuration, allowing the length of the large current carrying signal path to be shortened, and resulting in outstanding linearity regardless of the sound level.
