The Sigma Fabrications Stage Monitor
is extremely rugged, constructed from 9mm birch ply and covered with our distinctive, hard wearing charcoal grey carpet - so it keeps its appearance on stage and is a 2-way active wedge monitor.
Driving the Sigma Fabrications MB4 Stage Monitor
Generally use a Klark Teknik DN9848 to run 4 mixes and have a specific programme for the MB4, which has been in development since the first was launched in 2001. Alternatively you can use a Nexo NX processor with the programme installed, or a Camco Vortex 4 with a Camco processing card slotted in the back. This was specifically developed for the MB4 by Camco and makes the Vortex 4 an MB4 specific amplifier with one channel providing the HF and the second providing the LF.
