The wireless receiver is connected to your sound system or amplifier using regular RCA cables. Usually, they have a transmitter that is connected to the PC via USB.

Wireless DACs: If you want to send the audio to a sound system with wifi or Bluetooth capabilities, you can use this type of DAC. These can be used to boost the headphone output with your laptops/PCs, cell phones, and music players. Portable DACs: commonly found models are USB powered, with a built in battery for extra portability. These DACs use either a USB power supply or require AC outlet.

When you play these files on your PC or iPod, they have to be first converted from digital to analog format to enable the hardware (your speakers or earphones) to play them as music. These days, almost all music and audio files are stored in digital formats like MP3 and FLAC.
