Luxman L-507Z
Beschrijving / Description
Luxman's new generation Z series integrated amplifiers. The L-507Z is the debut model heralding our new generation of amplifier products. Featuring our newly developed LIFES amplification feedback engine, we look towards the future of Luxman. This amplifier has realized a dramatic development in musicality that goes far beyond its class. L-507Z combines advanced technology and sophisticated functionality. Our new, innovative Z series integrated amplifier generation begins with this superb model.
Our latest amplification feedback engine brings music to life with LIFES Version 1.0
Luxman will celebrate our 100th anniversary in 2025 and we are proud to announce the successor to our ODNF* feedback circuitry, which has contributed to the audio quality of our amplifier products since 1999. We have developed a new amplifier feedback circuit, LIFES*, which has acquired realistic, fresh and rich musicality and overwhelming audio performance. LIFES is based on the technical concept of our epoch-making ODNF circuit and realizes excellent, dynamic characteristics without feeding back any of the original audio input signal to the main amplifier, achieving a remarkably natural sound quality, almost if it were a non-feedback equipped circuit. The design has been conceived and expanded upon from first principles using simulation technology and painstaking research. By repeatedly auditioning, rigorously scrutinizing and combining specially selected components, we have achieved supreme performance characteristics and a level of quality suitable for use in Luxman's next-generation products. In producing LIFES Version 1.0, by carefully reimagining the entire circuit, we succeeded in reducing the number of paralleled elements while improving performance. The distortion in the amplification stage has been reduced to less than half of our previous system. The output stage features a 3-stage Darlington triple-paralleled push-pull configuration and achieves a class AB power output of 110W+110W (8 ohm) and 210W+210W (4 ohm). The high output power, comparable to that of a separate power amplifier, effortlessly realizes a natural soundstage, full of energy, to confidently drive any compatible speaker system, and bring out the best of its characteristics.
*ODNF stands for Only Distortion Negative Feedback.
*LIFES stands for Luxman Integrated Feedback Engine System.
Large needle VU level meter and 7-segment LED
Needle-type analog VU meters are a symbolic design statement of Luxman's solid state integrated amplifiers. The L-507Z is equipped with a large dual meter with bright LED back-lighting and high response characteristics. We have adopted such a display so the movement of the needles synchronizes with the dynamics of your music. In addition, newly included 7-segment LEDs display the attenuation level in between the left and right level meters so that the current attenuation amount can be easily seen from the listening position. The level meter back-lighting and LED display can be turned on and off using the remote control.
