DESIGN & TECHNOLOGY 设计与科技:
- QuarterA system ensures fixed bias current until 30W power level, switching to Class AB from 30W to 120W.
- Electronic switching circuit for seamless operation transition developed by Marantz.
- Power amplifier section uses a fully push-pull DC configuration with built-in DC-servo circuit.
- Low-TIM design reduces transient distortion and minimizes NFB for improved performance.
- MC cartridge dedicated headphone amplifier with 13 transistors per channel in a 4-parallel push-pull input stage and SEPP configuration output stage.
- Phono amplifier uses Marantz's unique push-pull circuit for all stages to achieve high SN and dynamic range.
- Equalizer uses metal-coated resistors (1% tolerance) and polypropylene capacitors (2% tolerance) for excellent characteristics.
- Tone switch bypasses the entire tone amplifier circuit for purer sound.
- Small large-capacity power transformer with improved heat resistance using special resin.
- Super audio condenser of 22,000 μF x2 selected for sound quality.
- Heat pipe system ensures stable operation even under the high current demands of pure Class A.
- Two phono inputs, including MM load settings (27k Ω, 47k Ω, 100k Ω) and MC head amplifier position.
- Functions include a tape copy switch for dubbing, two levels of loudness, and independent tone control on both channels.

- QuarterA 系统确保在30W功率水平下固定偏置电流，功率从30W到120W时自动切换到AB类。
- Marantz 开发的电子开关电路实现了无缝的操作切换。
- 功率放大器部分采用全推挽DC配置，内置DC伺服电路。
- 低TIM设计减少瞬态失真，最小化负反馈以提高性能。
- 为MC唱头设计的耳机放大器，每通道13个晶体管，采用4并联推挽输入级和SEPP配置输出级。
- 唱放部分采用Marantz独特的推挽电路配置，以实现高信噪比和动态范围。
- 均衡器使用金属涂层电阻（误差1%）和聚丙烯电容（误差2%）以获得优异的特性。
- 音色开关可绕过整个音色放大电路，以获得更纯净的声音。
- 小型大容量电源变压器，使用特殊树脂填充，提高耐热性。
- 22,000 μF x2 超级音频电容，精心挑选以保证音质。
- 热管系统确保在纯A类大电流需求下仍能稳定运行。
- 配备两个唱放输入，其中Phono1具有27k Ω、47k Ω和100k Ω MM负载设置，以及MC前置放大器位置。
- 具备双卡带复印开关、两档响度调节和双声道独立音调控制等功能。
