Rebel LIVELONG PHONO 810H MC MM amplifier

Rebel LIVELONG PHONO 810H amplifier MC MM       

REBEL LIVELONG PHONO 810H specifications are as follows: 

l appearance: W * D * H (19.2 * 24 * 5/CM) 

l Weight: 1.5/kg (including a separate power supply) 

l function: MC / MM phono can switch 

l Input Sensitivity: 3mV (MM), 0.15mV (MC) 

l magnification: MC/61dB, MM/34dB 

l the RIAA deviation: 20Hz ~ 20kHz (± 0.2dB) 

l architecture: a special custom filter regulator module for power supply. 

Popular composite differential crystals, linear IC for amplification and servo. 

  3.RIAA attenuation in high frequency, low frequency feedback the individual paired treatment design (error <0.2%) 

  Selected parts: nearly all of German-made 0.1% precision resistors, audio-class German-American day capacitors and Xsymphony the OCC line of separation. 

  5 chassis aluminum alloy and anodized to create rose gold plated RCA female gold-plated grounded head. 

  Separate power supply for the sake of the ultra-low noise. 

l Other: with electronic repair capacity can open the cabinet to replace the plug-R18, and R27 of the resistance to match the different MC cartridge impedance. 

       Rebel, 801H is very simple to use, direct plug in transformer, Rebel, 801H on the boot to work. Phono amplification often eliminating the need for the power switch, on the one hand, the hope that users do not shutdown, phono amplification to maintain the best working conditions, but they're also streamlining the line, reduce contact. Front of the lights switch to red and blue, two red for MM zoom, Blue MC enlarge.

  
Simply the MM / MC switch, while simple, but the Rebel, 801H also eliminates the need for MC cartridge impedance matching function. Generally sing the head to enlarge the impedance matching, multi-use DIP or Jumper switch setting, the advantage is with the adaptation of the cartridge to match a wider range, but there are disadvantages, general DIP switches or Jumper not to sound design, materials and quality just to stable asks the voice, although convenient to use, but may therefore deterioration of the sound. Rebel, 801H is set corresponds to the impedance of most of the cartridge, if users need, Rebel to replace the drug resistance can be. Internal board of R18 and R27, two resistors, and mining can change the design, no welding can be replaced to match the resistance. DIY expert can naturally do it yourself, or inform the MC cartridge impedance values, the Rebel handle, without additional charges.

Open the Rebel, 801H internal, neat and simple lines, in an effort to low-noise hearing, choose a modern performance of the OP. OP zoom, Hi-End audio industry have been taken seriously, but after a Mark Levinson, Cello., Mbl predecessors manufacturers design classic equipment, we discovered that the original OP listen better than the line using the crystal puzzle. Rebel, 801H selected Burr-Brown OPA134PA, before the European system level prefer to use the new the OP. OPA134 with the combination of the LT1028 is the common choice for the price of European Department of phono amplifier, such as Germany JR Transrotor Phono II with TA PH2000, coincidentally are the combination of apparently great minds think alike.

RIAA equalization circuit design creative

Phono pickup signal is very small, so the use of modern OP performance of high magnification and low-noise hearing, it is reasonable to design logic. However phono amplification Another problem is that the RIAA equalization. RIAA equalization, common standards promulgated by the U.S. Recording Industry Association, engraved in the record, the low frequency to be attenuation, high frequency will have to be compensated, so that the record groove in order to maintain the appropriate width, in turn, amplified by the phono RIAA equalization is to reply to the face of the original signal. How to reply, that is the problem of the RIAA equalization.

  
General RIAA equalization is divided into two categories, respectively, is of feedback type and (NF EQ) and attenuation type (CR EQ), feedback type of advantage is fewer parts, low noise, but 20Hz ~ 20kHz between the frequency will produce about 40dB equalization loss. The relative attenuation type of advantage is not of NF EQ equalization loss, less distortion, but the Noise. The two lines are a common pattern, each with its own advantages and disadvantages. Rebel, 801H how the election? Mr. Lu is clearly 箇中 players, he wanted to fish and eat it too, the high frequency part of the CR attenuation EQ, low-frequency part of the NF-feedback type the EQ, mix and match up of the loss can be reduced and other, while maintaining low distortion the requirements of circuit design is quite creative.
