Technics SE-R1 Power Amplifier
Stereo Power Amplifier SE-R1
Sets a new high performance standard for digital amplifiers by employing
state-of-the-art components and innovative technologies.
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.
LAPC (Load Adaptive Phase Calibration)
The impedance of a speaker is not constant: it varies according to frequency, thus altering the loading on an amplifier and therefore potentially the sound. Technics is able to measure an amplifier's frequency amplitude-phase characteristics with speakers connected, and has developed a speaker impedance adaptive optimization algorithm using digital signal processing to achieve ideal impulse response. Correction processing based on the new algorithm achieves a flat frequency response for both amplitude and phase, not possible in conventional amps, and delivering a sound with rich spatial expression.
