Luxman EQ-500 MM/MC Valve Phono Amplifier
The joy of analog reproduction is the indulgence of the harmonic density and tonal character of vinyl playback, faithfully reproducing sound vibration and resonance inscribed on analog records without interruption. The EQ-500 phono equalizer amplifier is a vacuum tube design for all stages to provide the ultimate experience in the expressive and colourful reproduction of music. Fine adjustment and switching functions that are easily accessible on the elegant front panel allow you to enjoy the real pleasure of analog reproduction. The debut of LUXMAN’s masterpiece phono equalizer amplifier, the EQ-500, brings a new dimension that offers an extensive menu of the finest details of analog reproduction allowing you to recreate that ideal sound from your memory.
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.
