Shell Specifications:
- Housing size: 215 x 308 x 62 mm (WxDxH)
- Internal dimensions of the shell: 203.5 x 297 x 54 mm (WxDxH)
- Shell material: all aluminum panel, all aluminum body.
- Color: bright silver panel, black body, transparent rubber feet.

Control System Configuration:
- Control Panel: VFD display is used. EC11 type encoder with pushing switch. The distance between two encoders is 168mm, and PCB board is tin-sprayed.
- Power Supply Board: Onboard high-quality all-copper sealed transformer (if you need a 110V transformer, you need to replace it with our customized EI transformer). Onboard 30A power relay is used to control the power supply of preamp or power amplifier, and the onboard rectifier and voltage regulator circuit outputs +5V voltage for stable use of the system. On-board rectifier and voltage regulator circuit, output +5V voltage for stable use of the system. High-quality power supply terminals are convenient and easy to use, PCB board with tin spraying technology. (The power supply board may not be exactly the same as the picture shows, the actual product shall prevail)
- Audio Source Switching Board: Input and output integrated board design is adopted, and the rear panel of the case is directly installed, which takes up less space. It adopts all-copper gold-plated RCA signal base, signal relay, two-channel independent ground wire, independent input and output ground wire, 4 sets of signal input options, and two sets of immersion gold PCB boards.
- Volume Control Panel:
* Relay + Resistance Array Version: Default signal relay, 1/4W precision resistor or 1/4W color ring resistor, two-channel independent ground wire, and PCB board with immersion gold technology.
* ALPS Motor Potentiometer Version: Original ALPS-RK168M type 4-link motor potentiometer, and PCB board of immersion gold technology.

Package Included:
- 1 x Set of Volume Controller

Note:
- The display color of digital tube on the control panel is red by default. The available colors are: white, yellow-green, emerald green, and blue.
