Technics SE-R1 Stereo Power Amplifier:

The SE-R1 is a stereo power amplifier engineered to set new standards in digital amplification, employing state-of-the-art components and innovative technologies.

Accurate Digital Technology:

• JENO Engine (Jitter Elimination and Noise-shaping Optimization): Reduces jitter across the entire frequency range, reproducing natural and delicate nuances of music.
• GaN-FET Driver: Utilizes high-speed gallium nitride FET drivers with super-low resistance, enabling high-power amplification with outstanding linearity.
• LAPC (Load Adaptive Phase Calibration): Measures the amplifier's phase characteristics with each speaker it drives to achieve a flatter frequency response.
• Technics Digital Link: Transmits digital audio signals and volume control information directly to the power amplifier, minimizing degradation and ensuring superb stereo separation.

High-speed Silent Linear Power Supply: Ensures stable and clean power delivery to the amplifier circuits.

Battery Driven Clock Generator: Shields the clock circuit from AC line noise by using a battery-driven clock generator, providing a cleaner power supply to sensitive circuits.

Dual Mono Construction: Separates the left and right channel signal paths to eliminate interference and achieve clear stereo imaging.

High Rigidity Metal Double Chassis: Constructed with a 7-mm-thick aluminum plate to resist electromagnetic noise and reduce vibration.

Output Power:

• 150 W + 150 W (1 kHz, T.H.D. 0.5%, 8 Ω, 20 kHz LPF)
• 300 W + 300 W (1 kHz, T.H.D. 0.5%, 4 Ω, 20 kHz LPF)

• Balanced: 1.2 V / 47 kΩ

Frequency Response: 1 Hz to 90 kHz (-3 dB,

The Technics SB-R1 is a Reference Class speaker system designed to deliver exceptional sound quality through advanced acoustic engineering.

Key Features:

Point-Sound-Source Speaker System: Utilizes a flat coaxial two-way speaker unit, combining midrange and treble drivers, to achieve precise imaging and soundstage focus. This design ensures wave-fronts from the drivers arrive simultaneously at the listener's ears, regardless of position, simulating a single-point sound source.

Phase Precision Driver: Features a flat mid-range diaphragm with a sandwich construction of lightweight, high-rigidity carbon cloth skins and an aluminum honeycomb core. This design maintains pistonic motion over a wide frequency range, eliminating distortions caused by the 'cavity effect' found in conventional cone diaphragms. 

Ultra Wide Range Reproduction: Equipped with a carbon graphite dome tweeter capable of reproducing frequencies up to 100 kHz, and a woofer extending down to 20 Hz, the SB-R1 covers the vast frequency spectrum of high-resolution audio sources. 

High Rigidity Entasis Form Cabinet: The cabinet features a 50-mm-thick baffle and side panels made from eight layers of MDF, forming a curved structure that suppresses unwanted vibrations and reduces internal and external diffraction and reflection. An internal partition divides the cabinet to eliminate low-order standing waves in the vertical direction. 

Low Distortion 16-cm Long Stroke Woofer: Developed to reproduce super-low frequencies with dramatically reduced distortion, this woofer delivers powerful, dynamic, and responsive bass. The push-pull edge design (Symmetrical Surround Technology, SST) cancels secondary harmonic distortion in the low-frequency range.

High-Quality Network Circuit: Designed to maximize the performance of each speaker unit and achieve balanced sound, separate network boards for woofer, mid-range, and tweeter are optimally arranged inside the cabinet to prevent interference and minimize vibration effects. 

Specifications:

Type: 3.5-way, 6-speaker, bass-reflex system (including coaxial 2-way for mid-range and tweeter)

Speaker Units:

• Woofers: Four 16 cm (6.5 inches) cone-type
