When connecting a microphone we suggest that you use a wireless microphone. This requires the transmitter to be compatible with the SOUNDBOKS through the Aux-cord. 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 sound quality possible.
You can also connect a mixing board, however, the SOUNDBOKS does not come with the appropriate cables and therefore you have to get an RCA-to-minijack cable to use it with your mixing board. The RCA connector will fit your mixing board while the minijack connector will match the AUX input of the SOUNDBOKS.
When connecting a guitar just make sure to use a guitar effect processor pedal or something similar with a line or a headphone output.
If you own a PROBOKS, you can use this to connect instruments and microphones.
