When it comes to connectivity the SmartRig Plus does not disappoint. It has two XLR combo inputs that give you the ability to plug in two XLR microphones or two ¼” musical instrument jacks. Alongside these are two 3.5mm mini jacks which can add up to four audio sources at the same time. Be aware though the Saramonic SmartRig Plus is a two-channel device and it will mix down all of these inputs to two channels.

Gain Control

You can adjust the gain on each channel individually with the decent sized knobs on top of the unit, just like you would find on a proper audio mixer. The audio channels can be set to stereo which will mix all inputs to a stereo file or set to mono which will give you control of each channel independently.

Phantom Power

The Saramonic SmartRig Plus has built in phantom power if you need to power external microphones. You can turn this on or off as needed so you don’t damage microphones that do not need it. You can also set the unit to connect to a DSLR or other standard audio device. There is a switch that sets the SmartRig Plus to a signal that will support a TRS plug which is the standard stereo mini jack that will work with most audio recorders or mixers. Switch it back to the Smartphone position and it turns it into a TRRS mini jack that is compatible with all Smartphones with a 3.5mm mini jack. This is a brilliant feature that gives you two devices for the price of one.
