Yes, you can! We suggest that you use a wireless microphone. However, if you wish to use a microphone with a wire, just make sure to use a preamplifier to get the full experience and best quality sound possible.
And by the way, our PROBOKS might as well be something you'd be interested in... This baby is a preamplifier that includes XLR, RCA/phono, 6.3mm jack inputs, a mini jack and it will allow you to lock up to six SOUNDBOKS, connect microphones and musical instruments.
