With all dual-input interfaces I recall having tested, they all monitor the left channel source in the Left ear of stereo headphones, and the Right channel in the right ear of the headphones, except if the interface has a mono mode for recording, or a specific mono mode for monitoring. However, even though the Rig Pro Duo I/O does not offer any switch for mono of either type, when monitoring the discrete inputs are surprisingly centered in the connected stereo headphone. This is not a problem, but it is indeed worth noting.

On the MacBook, it powers up and I am able to select it as my Input Source. Can also hear some static hiss coming out of the laptop speakers. They told me to use the USB-A cable with an adaptor to USB-C instead. This works. I now have power to the iRig when plugged into the iPad.So I wonder which free Android recording device is recommended to recording and jamming on an Android phone. As I have covered in prior articles, to set your audio sampling on Android or iOS, simply select it in any of the recording apps that offer such an audio sampling selection (i.e. Auphonic, FiLMiC Pro, FV-5 Cinema) or use an app that uses 48 kHz exclusively, like the RØDE Reporter app. (Stay away from the native camera app or GarageBand, which only support 44.1 kHz, which is kryptonite for video production.)

The iRig ASIO drivers enable professional level audio control over your iRig hardware. With the iRig ASIO drivers, it allows for adjustable buffer sizes and optimal control for ultra low level latency. Overall, performance with ASIO is better and much more stable, resulting in less dropouts and audio processing issues.The upper left LED is to indicate whether 48 volt phantom power is active or not. The upper right LED indicates whether MIDI is active (which I did not test). As I have covered in many past articles, we record at the conservative -12 dB for a raw recording, to leave headroom for unexpected loud sounds like laughter or screams. In my test recordings which you’ll hear ahead, I set the input potentiometer to 90% to reach -12 dB with my normal voice level close to the mic. Fortunately, the preamps sound quite clean even at 90%. The context in which you play, record and perform will determine how much the portability factor will matter to you. Yes, you can indeed connect an unbalanced electret condenser microphone to the iRig Pro Duo I/O, as long as you use a VXLR+ converter (illustrated above, covered in these articles). The VXLR+ accepts the 48-volt phantom power from the iRig Pro Duo I/O and converts it into lower voltage bias voltage (plugin power) for these microphones, while adapting the connections. I tested it with the iRig Pro Duo I/O and it worked perfectly well, either with an XLR cable or by plugging the XLR+ directly into the iRig Pro Duo I/O’s XLR input. Above, headless Q2U’s directly digital output, flat (to compare with the preamp and A-to-D converter in the iRig Pro Duo I/O).

The iRig Pro Duo I/O is compatible with both iOS and Android devices which makes it a great option for a super portable recording rig (if you want better sound quality than your phone mic!) However thisinterface isn't just for mobile devices. You can connect the iRig Pro Duo I/O to a PC or Mac via USB - great if you're travelling with a laptop but don't want to carry a larger audio interface around with you. PowerBoth the 48V and Direct Monitor switches are turned off. But I have also tried with them on and get the same result: no audio reaches either the iPad or the MacBook. The new preamps on iRig Pro Duo I/O promise an extra 2 dB of gain over the previous iRig Pro Duo. When plugging in a condenser mic and recording some simple voice recordings, I didn’t notice or hear a difference based solely on increased gain. What I did find helpful was that rotating the gain knob was more tactile and transitions between gain levels weren’t as jarring as on the original iRig Pro Duo. High frequencies sounded a bit richer, but didn’t significantly change tonality. The PSU is great to get around always needing batteries, especially if you are not being mobile with the unit.
