IK Multimedia’s new iRig Pro Quattro I/O has many applications and an abundance of connectivity in one compact device. It can be used for mobile field recordings, podcasting, broadcast video and streaming where you want more control over your audio. On the top portion of the iRig Pro Quattro you have the LED meters at the top, four volume controls for the mics/inputs, a headphone level and line out level control. The four microphone inputs (two on the front and two on side) will accept XLR or ¼” inputs. For condenser mics there is a 48V switch for both pairs of channels plus 2 x RCA inputs ana 3.5mm line in for channels ¾. On the left side of the Quattro, we have Midi in and out, headphone output and 2 x XLR balanced outputs for channels one and two for stereo. At the bottom there is (V DC, USB power and a host plug in or you can power the Quattro with the included AA batteries. A connector clip is included for the back of the device so you can mount it on a stand or video camera for easier control and cables are included too. The iRig Pro Quattro I/O can interface with your iPhone, iPad, Mac/PC or Android devices. It also includes free software such as AmpliTube 5 SE, T-RackS 5 SE and two other titles of your choice. The Quattro is an incredible tool for making your audio sound better, use of multiple microphones and inputs simultaneously and total controlling on mixing the audio to one or more output devices. Other single channel interfaces on the market are limited on control and only provide a single output option. The iRig Pro Quattro I/O is a handheld portable mixer/interface that provides total control of your mics and audio so that levels are balanced, and sound quality is superior. If you are streaming your performances on social media or your website the Quattro can make you sound much better than the built in microphones on smartphones, tablets or computers. But keep in mind the microphones are not included you must still provide those. Podcasters this is one device that will let you mix yourself and three other quests at the same time. The iRig Pro Quattro I/O is an amazing audio tool that is cost effective for all it does!
