HIFI fever tube preamplifier CV181SE PSVANE C1 bile preamplifier 6H8C

C1 hifi high and low pitch adjustment front amplifier voice ofPSVANEcv181Pre-biliary

everyone knows that the front stage makes a sound and the latter stage makes a contribution, but it is more difficult to make a good front stage than the latter stage. A front stage should have low noise and low distortion, which can improve the listening resistance of the latter stage, however, most of the courageous levels lack a very practical adjustment function of high and low pitch, and most of them are abandoned, because it is not good enough to increase noise and distortion, which is a function of increasing complexity and making efforts not pleasing others, once it is done well, it will make people feel bright, transparent and round with the addition of the sound of the front level. The details will be enhanced, and the low-frequency bouncing force and thrust will be greatly increased. There is a feeling that the more you listen, the more you love listening and the more you can't put it down, let a set of even ordinary systems have a completely new improvement.

Referred to Ma 7, Hetian Mao and so on, and finally gave up imitation and designed C1, a simple, durable, unique, high-fidelity preemptive amplifier that continued his own style. I would like to thank Mr. Cui, the noble voice electronic tube, for providing the cv181-se with excellent performance, which provides a basic guarantee for the perfect interpretation of the sounds of nature.

Don't say that HIFI only needs high-fidelity direct amplification. In fact, various program sources have already been changed by various tuning facilities in the recording studio. We can only approach but never restore live music. Restricted by the limitations of players and speakers, it is impossible for a 3-inch trumpet to produce the loose and natural low frequency of 12 inches. Some friends say that the sound is dry and inaudible after matching the Gall machine, because the straightforward function depends too much on the matching of equipment, and this front level can just improve this problem, so that you can adjust your favorite voice.

Features and parameters of this machine:

1. 
   

   
   it has the straight-through amplification function of the common preemptive level, and has added moderate adjustment of high and low pitch, which can adjust the tone color according to preference, and make the details of music clearer and more listening-resistant under the low volume. Whether it is matched with a gallstone machine or a stone machine, it can not only Polish, but also enhance the high-frequency resolution, the low-frequency strength and the overall dynamic range.
   

   
   


2. 
   

   
   Extremely low noise can be basically ignored, with a minimum volume of 0.08 millivolts, a volume of 0.7 millivolts, and a signal-to-noise ratio as high as 96db,
   

   
   

the distortion degree is about 0.15%, the frequency response curve is flat, and all indexes are actually measured.

   External large margin el pure copper transformer, 10h inductance, clc filter, bile rectification linear voltage stabilization, two-stage direct coupling cathode output circuit, all red electrolysis, rel fever coupling, Weima tone, high-precision metal film Resistance, 5 pure copper gold-plated fine steel ceramic tube holders, Omron relay is responsible for 4-way input and high-bass intervention switching, reasonable matching components and layout make the appearance and performance of the whole machine reach the ideal state.
   

   
   


2. 
   

   
   The rectifier tube adopts the old Nanjing brand-new direct-heat rectifier tube. The standard configuration is matched with 4 Russian 6H8C, and the high-end configuration is matched with the voice of nobility 4 gall CV181-SE. The pipe will be replaced within one year.
   

   
   


3. 
   

   
   The whole machine adopts a large box with standard size of 43cm and a double head design with stable atmosphere. It is convenient to change the tube outside the bile duct to increase the playability. The net weight is 12kg and the package is 14kg.
