When connecting a microphone we suggest that you use a wireless microphone. This require that the transmitter is 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 quality sound 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
And by the way, our PROBOKS would probably be helpfull on all of these potential setups. The PROBOKS is a preamplifier that includes XLR input, RCA/phono input, 6.3mm jack inputs, one mini jack input and it will allow you to Hook up to six SOUNDBOKS, connect microphones and musical instruments.
