The iRig Pro Quattro I/O is a fourinput, two-output portable audio and MIDI interface that can also be used as a standalone microphone preamplifier or a line mixer (see Figure 1). It can be used to facilitate recording to a mobile device, computer, DSLR camera, or connected directly to a PA system. The input and output connections are located on the top, bottom, left, and right panels, with the top panel reserved for controls and meters. The interface has four combination XLR/1/4-in input jacks. The first two double-up as Hi-Z instrument inputs and the second two can act as line inputs. Two further line inputs are available on a 1/8-in mini stereo jack input and RCA ports. There are microphone preamplifiers included on all four XLR inputs, with phantom power that can be switched on/off for pairs of channels. There is also a mini-jack input and output for MIDI. The interface has a stereo line output on 1/8-in mini jack port (unbalanced), and left and right XLR outputs (balanced). It also has a miniDIN connector for connecting to external devices. A number of cables are supplied with purchase: lightning to mini-DIN, USB-C to mini-DIN, and USB-A to mini-DIN.

The interface supports sample rates up to 96 kHz at 24-bit depth. It has a built-in omnidirectional microelectromechanical systems (MEMS) microphone that has a frequency response of 30 Hz to 20 kHz and a maximum SPL of 110 dB. The iRig
