Mark Levinson amplifiers No531H Monoblock design and ability to perform high-end audio.
With four different models, the Mark Levinson 500H legacy of the 400 already achieved much success. Basically, there No531H circuit design is similar to 532H, but were separated into 2 blocks Monoblock to provide greater capacity.
Technical design
All four models in the line No500H are covered with a black coat with slightly curved sides up on either side, so at first glance they are virtually identical. With a size 18cm high, 45cm wide and 50cm deep over, this is a pretty big amp, but fairly light weight (about 24kg) compared with its previous generation of amplifiers. The entire shell is designed to support the purpose of heating, because the amplifier does not use fans or heat sink exposed. Like the other products of Mark Levinson, No531H use convection cooling mechanism.
Specifications:
Power: 300W / 8 ohm
Frequency Range: 10 - 20.000Hz
Distortion: less than 0.5% (at nominal power)
Size: 177 x 451 x 50.4mm
Weight: 23.8 kg
No531H the back of the speakers have a pile head fitting using the company's tradition, the input signal can choose one of two types of balance XLR or RCA connections. Products using detachable power cord, a 12 volt trigger port and Ethernet port, which is compatible with modern sound system using an internet connection. 300W/kenh power level is at 8Ω (No400 higher line to 100W), the features of the 531H is extremely low THD distortion even at maximum capacity (less than 0.5%), as well as credit score signal / noise and flat frequency range from 10Hz to 20kHz.
In essence, as well as the entire line No531H No500H use the balanced amplifier circuit current feedback (CFA - Current Feedback Amplifier) exclusive Mark Levinson. Negative feedback (negative feedback) is a circuit was invented and used in the amplification equipment since the year 30 of the last century. Current feedback and voltage feedback are two modes are widely used in hi-end amplifier. With CFA circuit, amplification No531H be easily controlled without affecting the frequency range, and signal processing speed is super fast advantages of the CFA circuit than the voltage feedback circuit VFA (Voltage-Feedback Amplifier) normal.
Instead of using a few large capacitors and wiring to the motherboard power, amplifier No531H used pretty much smaller capacitors in parallel to match the power supply necessary for the amplifier. Thus, the child can be mounted together on the power circuit, suitable for those cases requiring the power supply immediately. Also by this design that the amplifier in the series No500H sound quality can bring more uniformity between the model together.
Try the sound quality
Try No531H amplifier with speakers of the JBL Everest K9900. By the spatial audio amplifier generates considerable depth, and it pushed the voice of the artist on the front, close to the listener, creating more realistic feeling. No531H bass fullness of nature, with highly detailed, in-depth achieved without the support of the sub that is not overwhelmed by the negative range. High bandwidth has improved significantly compared to its 400 line.
Ability to represent the true voice of No531H, subtle and inspiring. Instead the listener to turn the volume up high to reveal the level of the sound No531H boom is not limited entirely definitive, well-defined. It is extremely fast response speed of the music complex, but the sound quality of the amp does not "overwhelm" the audience that is quite subtle. In particular, the sound is improved in the first two frequency bands: very quiet and extremely high.
