Yes, Spark EDGE has two XLR ¼" combo inputs that can be used with either an XLR cable or a 1/4" phone jack.
Please note that Spark EDGE does not provide phantom power. If you'd like to use a condenser microphone, you'll need a pre-amp to power it before connecting it to the Spark EDGE.
You can save effect pedals and preamps for acoustic, bass, and vocal on both Input Channel 1 and Input Channel 2 on the Spark EDGE. However, Input Channel 2 can only load effect pedals and preamps specifically designed for acoustic, bass, and vocal.
