Description
Brand: Qiter
Color: Default
Characteristics:
- 【Good Practicability】Connect the 6J1 tube preamplifier between the sound source and the amplifier, it effectively filters the digital flavor, the music and the human voice will be relatively good.
- 【Professional Design】Eight 470UF capacitor filters are very clean, the excellent power supply system does not produce hum, the filaments are powered by 12V DC and need to be connected in series to reduce noise.
- 【Features】The coupling capacitor is an electrodeless electrolytic capacitor with high frequency and low resistance. Please choose your preferred option based on your actual needs.
- 【Easy to Install】Tube amplifier kit with a DC 5.5 * 2.1 jack and an AC 12V transformer, you can also use an AC 12V transformer without a plug, you just need to weld the power cable onto the board.
- 【Easy to Use】This electronic amplifier kit comes in parts so you can assemble them yourself, enjoy the process of building your own tube amplifier.

Channel types: 2.0/Stereo
Voltage current: AC12V 0.8A or higher
Power interface: 5.5 * 2.5 connector

Instruction :
1. AC 12V Input: With the DC 5.5*2.1mm jack and AC 12V transformer, you can also use a plug-free AC 12V transformer. You only need to weld the power cable to the circuit board. The DC input cannot be used or will not work.
2, Sound Channel Input: Connected to mobile phone, computer, MP3, MP4 and many other music players.
3, Sound channel output: Connected to the audio signal input of the power amplifier.
4, Power/Volume Control: Turn the knob counterclockwise to decrease the volume, and continue turning until you hear the "tick" to turn off. Turn the knob clockwise until you hear the "tick" to turn on, and continue turning to increase the volume.
