Luxman M-700u Stereo/Mono Amplifier

Stereo output is rated at 120W per channel into eight ohms and 210W per channel into four ohms, achieving up to 840W per channel into one ohm instantaneously. There is also a user-selectable mono mode with a rated output of 420W into eight ohms. In order to achieve this level of power without sonic compromise, Luxman has implemented its ODNF 4.0 drive circuit utilizing a four-parallel push-pull structure with three-stage Darlington. A Luxman ‘Ultimate Efficiency Power Transformer’ – an EI type rated at 550VA – forms the heart of the amp’s power supply, with plentiful regulation ensuring an unshakable response to any load fluctuations. A high-capacity block capacitor contributes to the M-700U’s ability to deliver lashings of power instantaneously yet remain firmly in control, while the amp’s low-impedance transmission design, carefully selected custom components and short, fully optimized signal paths deliver maximum sonic purity. In classic Luxman style, the M-700u sports two illuminated VU meters, one for each channel, giving a real-time indication of signal level that’s both a satisfying visual accompaniment to the music and a useful guide to how hard the amp is being pushed. Around the back are both single-ended RCA and balanced XLR inputs, heavy-duty speaker binding posts, switches for stereo/mono modes and phase inversion, plus a remote input terminal for custom installations.
