Masterblast™ (Legacy Product)

City Theatrical MasterBlast (legacy product) is a battery operated LED lighting fixture with built-in SHoW DMX® (wireless DMX). Every MasterBlast is selectable to be either a transmitter or receiver, so one MasterBlast can serve as both a lighting console and wireless transmitter, sending out a show of built-in routines to many other MasterBlasts.

The MasterBlast utilizes City Theatrical’s interchangeable polycarbonate holographic lenses in nine different symmetrical and asymmetrical beamspreads, and is compatible with the full line of City Theatrical power/data supplies for Color Kinetics. It has 14 or more hours of battery life when using a rolling color change, a battery that recharges in two hours, a very bright 50W color changing Philips Color Kinetics LED fixture, and a user friendly user interface.

Setting Up A Basic System

Here's one way to use MasterBlasts.  Set one unit as a Transmitter and broadcast your show to an unlimited number of  MasterBlasts set as Receivers. Use the built in routines to set color fades or fixed colors.  Use the built in grand master to set the overall intensity of the show or to increase battery life. 

Note:  The Transmitter in these diagrams are shown out of proportion to the Receiver.  All units are the same size since all are selectable as either Transmitters or Receivers.

Setting Up A System With Both Wired And Wireless Equipment

Here's another way to use MasterBlasts in conjunction with wired City Theatrical PDS-750 TRs or PDS-375 TRs.  Using the DMX output of the Transmitter, connect via a DMX cable to a PDS-750 TR or PDS-375 TR and the same show that you are broadcasting to your MasterBlasts will be output through your PDSs.  Set up large installations this way with minimal cable and no lighting console.
