Function details of TP50:
EVEL: Volume control during music playback, such as adjusting the volume level of music. It can also be used to describe the sound quality of an audio signal, such as adjusting the level of bass or treble.

ADJ-L/R: Balanced left and right channels.

FLT: Output the input signal in single-ended form. It means using single-ended output to achieve amplified audio effects.

DAC OM: is an output mode that converts digital signals to analog signal output to provide a listening experience closer to the original audio signal.

S/PDIF: A digital audio interface jointly developed by Sony and Philips. It is a series of protocol technology standards. It is widely used in digital signal transmission between current CD, DVD, DAT, VCD, MP3 players and other electronic devices. (Sony/Philips Digital Interface Format)

H-DEPOP: is a circuit used to eliminate unwanted crackles or clicks in a circuit, often quantified in terms of "pop performance". (High Dynamic Range Anti-Crackling/Suppression Circuit)

DISP BN: Display brightness.

DISP ROT: 180 rotating display

OFF-DISP: Screen lock duration.

HID KEY: Some or all of the amp's settings will be hidden or locked to prevent unauthorized changes. This allows users to focus more on the listening experience without having to worry about misoperations. (Avoid misoperation)

UAD FW: The meaning of firmware of Unified Audio Device Driver. UAD FW is the software running inside the headphone amplifier, which is used to manage and control various functions and parameters of the headphone amplifier. By upgrading UAD FW, users can get the latest features, fix known bugs, and improve headphone amplifier performance and stability. (Version)(Note: This is an explanation of the function details: the version is the latest and most consistent with the operation of the DAC, and does not need to be updated.)

RST DEF: Restore factory settings.

Button control: Press the M key twice to light up the screen, long press the M key to enter function switching, click +/- to increase or decrease the volume by 1 (0-100), and long press +/- to continuously increase or decrease the volume.

Switch between previous and next songs, pause: After the HID KEY switch is turned to ON, the M key is for pause/play, click the + sign for the previous song, and click the - sign for the next song. After turning on the HID KEY switch, the +/- keys cannot be clicked to adjust the volume, but can be adjusted by long pressing.

TP50 sound style: more analytical and controllable, the sound is slightly colder
