This product has a wide voltage supply and warm sound. It is an upgraded amplifier and a tool for improving vocals! The self-developed wide-voltage high-fidelity electronic tube pre-stage buffer line has the function of improving and improving the sound quality. It is connected to the CD or mobile phone audio output, and then connected to the post-stage power amplifier, which can improve the original digital sound and fill the vocal deficiency. Make music more dynamic and have a tube amp style!
The line adopts high-fidelity, independent and innovative high-fidelity, ultra-wide DC voltage supply line (DC: 6V to 24V) for perfect and continuous operation! The anode voltage boost of the tube can be automatically changed according to different working voltages, which is more in line with the selection of the power supply of the tube enthusiast. Because the tube sounds warm and the fidelity is high, the longer the tube works, the more resistant it is!
Adding the power amplifier of the pre-stage of the tube, with the tone and volume on the amplifier, you need to rotate all the high and low sounds and the total volume to the middle. After the pre-heating of the tube is reheated for 15 minutes, you can quietly enjoy it before you can produce the tube. It’s not the same warm sound effect. The circuit board components,
All the resistors are all made of five-color ring metal film, so that the imbalance error rate of the left and right channels is smaller, the output coupling uses 250V/1UF professional audio capacitor, the front-stage coupling uses bi-capacitor isolation, and the boost filter capacitor uses string. And array! (This product is black sandblasting, laser screen printing, never fade!
Working voltage (DC 6-24V)! The finished product size is 95X95mm, the circuit board adopts 1.6 thick double panel design, and the upper and lower sides are protected by 2mm thick aluminum plate).
