| SD card slot | 
			The built-in SD card slot allows the Mac mini (Mid 2011) to read and write data to SD media. The slot accepts cards that are Standard SD (Secure Digital) 4 MB to 4 GB, SDHC (Secure Digital High Capacity) 4GB to 32 GB, and SDXC (Secure Digital Extended Capacity) 32 GB and larger. | 
		
| Audio in/optical audio in port | 
			
			 The Audio In port accommodates both digital optical input and analog audio input. 

			Analog audio line input is accepted through a 3.5mm mini phone jack. The sound input port accepts line-level stereo signals up to 24-bit stereo 44.1-192kHz sampling rate. It also accepts a stereo miniplug-to-RCA cable adapter for connecting stereo equipment to the computer. 

			Optical audio input is SPDIF format and uses a standard TOSLINK cable with a TOSLINK mini-plug adapter, accepting up to 24-bit stereo and 44.1-96kHz sampling rate. 
			 | 
		
| Headphone out/optical audio out port | 
			The headphone / line output port accommodates digital optical audio output, analog audio output with a 24-bit, 44.1-192 kHz D/A converter, digital audio output up to 24-bit stereo and 44.1-192 kHz sampling rate and supporting encoded digital audio output (AC3 and DTS). For analog headphone / line output, use a standard audio cable with 3.5mm metal plug. For digital audio, you can use Apple iPhone headset with microphone or a standard TOSLINK cable with a TOSLINK mini-plug adapter. |
