In the beginning of its a centesimal 12 months, Japanese model Luxman has launched what it’s calling its “most interesting built-in amplifier but”– the L-509Z.
Introducing the producer’s “single-chassis separates” idea, the brand new, all-in-one flagship amplifier has, in keeping with Luxman, developed past the idea of a standard built-in amplifier.
Each the preamplifier and energy amplifier sections concurrently use the model’s new technology amplification suggestions engine, LIFES for the primary time. The quantity management is supported by Luxman’s new LECUA-EX attenuator system that suppresses sound high quality deterioration and realises a extra exact really feel of operation.
By feeding again solely the distorted elements generated within the audio sign’s journey to the ultimate amp stage, Luxman’s proprietary ODNF amplification circuitry is claimed to attain spectacular static traits and pure sound high quality as if it have been a non-feedback system.
The L-509Z is provided with unbiased LIFES modules, working concurrently in every of its totally discrete pre and energy sections. The L-509Z’s output part utilises three stage Darlington bipolar transistors in quadruple-paralleled push-pull configuration to attain the specified output energy and reportedly “close to excellent” energy linearity efficiency similar to a standalone energy amplifier, growing 120W+120W at 8 ohms and 220W+220W at 4 ohms.
A tactile, satisfying quantity management operate is crucial for audio amplifiers. To feed a hard and fast achieve energy amplifier with a musical sign at a stage appropriate for listening, exact management is required to easily attenuate the voltage whereas sustaining the standard of the enter supply.
LECUA, developed by Luxman, is an electronically managed attenuator system that switches via a collection of high-quality, fastened worth resistors for every channel independently. These are neatly organized on the sub-assembly in keeping with the place of the quantity management knob.
The L-509Z combines a extremely exact rotary encoder with a newly developed weighted rotation mechanism to create the LECUA-EX, which presents better reliability and a pure, high-quality operational really feel, whereas 88 steps from 0 to 87dB and an acceleration setting for the pace at which the quantity knob is rotated and a long-press setting for the distant management enable for snug and thorough quantity management motion with minimal degradation in sound high quality.
The L-509Z is provided with Luxman’s conventional, extremely secure energy provide circuitry, that includes a bespoke, extremely regulated 600VA El transformer and newly developed large-capacity filter capacitors (10,000μFx 8)
The built-in high-quality phono equaliser circuit, which helps each MM and MC cartridges, includes a new two-step achieve change to pick between excessive and low MC settings to accommodate a wider vary of MC cartridges, enriching high quality vinyl playback when it comes to each operation and sound high quality. And a Mute-Button is now featured on the entrance panel.
Along with bass and treble, a brand new center management efficient within the vocal and lead instrument frequencies bandwidth has been included. LR steadiness, line straight, loudness, and different features are additionally conveniently on the consumer’s fingertips.
Peel-coat circuit boards are used for the primary audio sign path, eliminating the damaging results of the coating movie that may adversely have an effect on sound high quality. Distinctive consideration has been paid to each element, such because the beeline development, which configures circuits to take the shortest route doable, and a non-angled wiring sample for easy sign transmission.
Massive, low resistance speaker relays are linked in parallel to transmit the driving pressure from the substantial energy provide and output circuitry. Inside, 3.5mm2 ultra-thick cable is instantly linked to the speaker terminals to make sure low impedance transmission, attaining a damping issue of 330 (present injection methodology).
The highest panel is made from ultra-thick aluminium with a hairline end. Massive air flow holes are fastidiously machined one after the other to make sure environment friendly warmth dissipation. Supporting the unit are 4 massive insulator ft comprised of forged iron, their density gradient defending the primary chassis from undesirable exterior vibrations.
The L-509Z is provided with two massive metres, brightly back-lit by LEDs, with delicate response traits. The newly included seven-segment LED show in between the left and proper stage metres shows the present attenuation quantity and is well seen from the listening place.
Along with the φ6.3mm normal terminal, a φ4.4mm terminal with unbiased left and proper grounding has been added for headphone use.
Unique excessive rigidity RCA terminals are used for LINE-1 and a couple of. Separate inputs and outputs for system enlargement are supplied with two pre-outputs, whereas two massive speaker output terminals with unbiased on/off switching enable for bi-wire connectivity.
The Luxman L-509Z is obtainable to order now at an RRP of £11,000 together with VAT through IAG UK within the UK.
