Features:

- It adopts double tube rectification, double tube regulation, double inductance filtering, 4pcs power supply filter capacitors, high frequency decoupling of large oil-immersed capacitors, imported resistor and military resistor, and components for WIMA, Siemens, and ERO.
- Panel is made of aluminum alloy with drawing process.
- Chassis and transformer cover are made of 1mm thick steel plate. Its shielding effect is good, using high-end wrinkle finish spray paint process.
- Power supply adopts a large toroidal transformer (wound by oxygen-free copper wire) and imported iron core, providing abundant power supply.
- The power transformer and two inductors are potted with expensive epoxy resin to realize fixation, moisture-resistance, insulation and heat conduction.
- 4ch input adopts imported silver contact relay switching, which has a longer life and smaller contact resistance.
- The input and output interfaces use gold-plated RCA sockets.
- The signal line in the machine adopts imported shielded wire to ensure good sound quality and excellent shielding performance.
- Tubes: 6N9P (6H9C)*2, 6N8P (6H8C)*2, 6Z5P*2 and WY-2P*2. The tubes are made by Shuguang or Nanjing tubes by default. Metal base and vinyl wooden base will be used based on stock.
- Functions of remote control: volume, channel switching and mute function.
- The volume adopts the original Japanese motor potentiometer for ALPS.
- Independent headphone jack for headphones to monitor the amplified output, using the MAX 4410 (for Maxim) as output.
- The volume knob is an expensive solid knob made of aluminum alloy.
- The panel is designed with equal loudness switches. Pressing the switch boosts high and low frequencies at low volumes to compensate for the sharp dip at both ends of the human ear's hearing curve at low volumes.
- The machine has a memory function: it can remember the channel status when the last shutdown.
- When the machine is turned on, the motor potentiometer will automatically return to the left and automatically unscrew a small angle to prevent excessive volume from damaging the equipment.
- When powered on, the channel status window will flash and alert the user that the device is warming up. When the warm-up is finished, the channel status window will stay on and display the current channel.
- Press the mute button of the remote control, and the channel status window will flash. Press the mute key again to resume music playing mode, or press the volume +/- buttons to resume playing mode.

After the warm-up is over, slowly unscrew the volume control potentiometer, and it can work normally.
(2) Phone: Headphone jack. Can be matched with 6.35mm headphones.
(3) Loudness: Equal loudness compensation switch. When this switch is pressed, it compensates for high and low frequencies at low volumes to compensate for the lack of hearing curves of the human ear.
(4) Volume: Volume control. Turn the knob clockwise to turn up, and vice versa. After booting, the knob will automatically return to its position with the left hand. When it reaches the starting position, it will automatically unscrew a small angle to prevent excessive volume from damaging the equipment.
(5) Channel status display window and remote control receiving window: it will display the current channel. When it is powered on, the window will flash to alert the user that the device is warming up. The window will flash when muted.
(6) Selector: Press this button to choose the source of input signal.
(7) INPUT: There are 4 stereo input ports.
(8) OUT: Stereo output. The 2 sets of outputs can be connected to 2 amplifiers at the same time, or one of the outputs can be connected to the subwoofer to achieve synchronous control.
(9) Supply voltage switch: Note that this switch should be selected in the appropriate position according to the local power supply system to avoid failure. Operation must be carried out in a shutdown state! It is 220V by default.
(10) AC INPUT: AC power supply input socket.
