INTEGRATED AMPLIFIER L-507Z LUXMAN CORPORATION
L-507Z features 新製品 1．Newly developed original LUXMAN amplification feedback circuit LIFES, at the heart of our latest Z generation amplifier series ※ 2．New LECUA1000 attenuator 3.
New generation feedback circuit LIFES 「LIFES （Luxman Integrated Feedback Engine System） 」 Since it was first installed in our CM-2100 car audio amplifier in 1999, ODNF has been refined as feedback system that forms the core of LUXMAN’s amplifier technology for more than 20 years. Constantly improved and evolved, over a dozen revisions across 5 generations.
New generation feedback circuit LIFES 新製品 「LIFES （Luxman Integrated Feedback Engine System） 」 ・High-performance FET adopted for voltage amplification stage Newly adopted high-performance FET that enables stable and continuous energy supply and redesigned circuit configuration, combining FETs and other transistors ODNF（P channel J-FET + NPN transistor） LIFES（N channel J-FET + PNP transistor） ※Compared to our ODNF circuit, distortion is less than half, S/N ratio improved by 3dB LUXMAN CORPORATION L-507Z’s p
New LECUA1000 「LECUA（Luxman Electric Controlled Ultimate Attenuator）」 ・Our original volume control system was first installed in the C-70f control amplifier in 2003 and has undergone continued development. ・ Volume control movements are detected and passed through to a microcomputer which controls the amount of volume change. The LECUA board, resistors with differing resistance values are selected via relays.
Discrete buffer circuit ・The output section of the preamplifier is equipped with discrete buffer circuitry as seen in our C-900u control amplifier ・Power amplifier driving force has been improved while maintaining the purity of the music signal ・Initial rise of the sound is sharp with an overwhelming sense of scale Discrete buffer circuit (※Picture shown an old model, L-507Z has different condensers) LUXMAN CORPORATION
Features The phono equalizer first stage input FETs are now paralleled to achieve even higher quality analog playback In addition to the standard Φ6.3mm headphone terminal, a new left and right independent Φ4.
Features Equipped with RCA input terminals made from a copper alloy which delivers conductivity of copper and hardness of brass (LINE-1) Highly stable power supply that combines a top quality power transformer and large capacity filter capacitors (8 x 10,000㎌) Custom made, large density gradient, cast iron feet that protect delicate music signals from vibration LUXMAN CORPORATION
