Product Description
description
 
The pre-amplifier version of the tube, the tube 6J5 is polished and enlarged. The tube has a bile taste better than 6J1, with high and low sound adjustment, Bluetooth 4.2 and analog input function.
 
Adding a tube to enlarge, Making the sound more Natural and Resistant,
The High Frequency is more Delicate, and the low frequency is Fuller.
 
Machine size: 102*80*138 (80MM is the height of the tube)
 
The user's audio source recording, speaker unit, and placement equipment are not necessarily perfect. The pure straight-through pre-level does not necessarily meet the demand.
At this time, the adjustment of the tone is very important. The effect of improving the high and low frequencies is obvious.
 
The best solution is to use the high, medium and low negative feedback tones of the Class A well-regulated power supply for both positive and negative pressures.
 
It has a delicate and natural tone, pure and thorough, and rich in layering.
 
The background sound of the board is very clean, the low frequency control of the music is better, and there is strength, and the midrange becomes smooth and soft.
