cd player disc changer

Most disc changers play standard audio CDs and read CD‑R and CD‑RW discs. For file‑based playback many models support MP3, and some also handle WMA, AAC, WAV and FLAC.

Disc changers range from single‑disc top‑loading players to multi‑disc units (commonly 3‑disc and 5‑disc models). Some multi‑disc designs use a fully opening tray or magazine mechanism that lets you load or swap several discs while one disc continues to play. Capacities and swapping methods vary by model.

Transports and rippers add features for digital output and archiving, for example: optical and coaxial digital outputs, USB digital output for external DACs, and CD‑to‑file ripping (automatic ripping to attached USB drives with folder creation and tagging support).

CD players commonly offer Bluetooth streaming, front‑panel USB playback, and a 3.5 mm AUX/headphone jack. Higher‑end units and transports add digital outputs such as optical and coaxial, and some models include IR in/out for installation control.

Many CD players play MP3 files from USB flash drives; higher‑end models also support WMA, AAC, WAV and FLAC. Some units specify support for WAV/FLAC up to 96 kHz/24‑bit and list maximum USB drive capacities (example: up to 128 GB).
