La alegría de la reproducción analógica es la indulgencia de la densidad armónica y el carácter tonal de la reproducción de vinilo, que reproduce fielmente la vibración y la resonancia del sonido inscritas en discos analógicos sin interrupción. El amplificador de ecualizador de fono EQ-500 es un diseño de tubo de vacío para todos los escenarios para proporcionar la mejor experiencia en la reproducción expresiva y colorida de la música. Las funciones de ajuste y conmutación precisas a las que se puede acceder fácilmente en el elegante panel frontal le permiten disfrutar del verdadero placer de la reproducción analógica. El debut de la obra maestra del amplificador de ecualizador fonográfico de LUXMAN, el EQ-500, trae una nueva dimensión que ofrece un menú extenso de los detalles más finos de la reproducción analógica que le permite recrear ese sonido ideal de su memoria.
RIAA-dedicated non-feedback CR type amplification circuit
All stages of the EQ-500 are vacuum tube. For the 1 and 2 stage a SRPP (Shunt Regulated Push-Pull) circuit is used which features low impedance, low distortion and prolongs the life of vacuum tubes. For the final stage a cathode follower parallel circuit is used with the ability to lower impedance further.The excellent sound quality of the CR circuit, supported by linear characteristics, is a direct result of the quality and accuracy of the parts used. LUXMAN has achieved the ultimate in high grade analog reproduction in the EQ-500 thanks to more than half a century of experience in manufacturing vacuum tube amplifiers and the selection of high performance parts. To protect minute analog signals from noise and magnetic field interference, the main sections of the EQ-500 are strongly shielded. The loopless chassis design of the EQ-500 isolates any ground impedance increase and magnetic field caused by the chassis current.
Stylish thin body with pointer type analog meters
The EQ-500 is housed in an elegantly thin chassis that can be mounted easily on a control amplifier. Stylish pointer type analog VU meters with a sensitivity selection switch monitor the output levels and sit on the blaster white front panel alongside a variety of additional control switches to create the sound close to your taste.
Optimizing the cartridge load adjustment
The EQ-500 features a load capacity selection function from which 6 levels (0/50/100/150/200/300pF) can be selected according to the characteristics of the cartridge to be used. Com bined with the load impedance selection function (30k to 100k ohms continuously variable) the original potential of the cartridge can be fully exploited.
All main control functions can be operated from the front panel of the EQ-500; articulator function (cartridge demagnetizer), 3 position gain selection, unbalanced/balanced output selection, phase invert, monaural mode, low cut and high cut switches.
An all-stage vacuum tube phono equalizer to suit diverse and specific tastes
The phono equalizer amplifier plays a unique role as part of an amplification system with respect to the characteristics and delicacy of signals. Because of this uniqueness, phono equalizers have been designed using various kinds of circuit methods and elements and have captivated the interest of enthusiasts for whom the detail of the sound is paramount. The EQ-500 is equipped with the circuit technology and musical essence inherent to its predecessor, the E-06 from LUXMAN. First launched in the 1980’s, the E-06 is still a highly respected masterpiece of the CR type. This renowned circuit technology has been newly improved in the EQ-500 and uses vacuum tubes for all of the amplifier elements to bring the spirit of analog sound inscribed on the vinyl discs into life.
Vacuum tubes manufactured by JJ Electronic in Slovakia
The vacuum tubes specified for the EQ-500 are manufactured by JJ Electronic in Slovakia and have a reputation for high quality and superior performance. The characteristics of the gold plated ceramic tube sockets are ideal due to their solidity and low contact resistance. A stable voltage can be supplied to the amplification circuit using a rectifying tube and a choke coil.
Large output transformer and 4 units of MC transformers
A large-capacity output transformer as well as MC step up transformers each playing a critical role in determining the sound quality and performance are made of super permalloy that particularly enhances the response to small signals. In addition, 4 units of MC step up transformers are mounted for MC-HIGH, MC-LOW, right and left independently.
Original custom built parts
The coupling capacitors that have been chosen for the EQ-500 are manufactured by Mundorf in Germany, world renowned for their ‘Audiophile’ tenacious tonal quality. Original custom built components are abundant in the design of the EQ-500 ensuring the ultimate in sound quality and reliability for each circuit including OFC internal wiring.
The high-rigidity insulator legs carved from solid block aluminium to suppress any vibration reaching the internal circuits of the EQ-500.
