The Formula Sound FSM-400 is a fixed format mixer designed for the professional DJ or small installation.
 
Formula Sound are recognised as one of the leading manufacturers of audio equipment and the FSM-400 is built to their usual high standards of construction and audio quality. Although the FSM-400 is a fixed format design the use of individual circuit cards per channel improve reliability and aid servicing should the need arise.
 
The FSM-400 is primarily aimed at the professional DJ but will also be used in smaller installations where a four channel mixer with each channel switchable to two inputs can be utilised.
