BACK PANEL AND CONNECTIONS
MAINS SUPPLY - 100-130/200-240V, 50-60Hz, single phase, 15 watts max.
MAINS VOLTAGE SELECTOR - MUST BE set for 120V / 240V.
MAINS SWITCH - With indicator neon.
MAINS & LAMP FUSES - 1 Amp, 5 x 20 mm.
MAINS SOCKET - IEC 22, 3 pin, male socket (kettle socket). A moulded lead with IEC female socket to British
13amp plug is provided. To fit another type of plug, cut off the British 13amp plug and observe the following
colour code: Brown = Live (Hot), Blue = Neutral, Green/Yellow = Earth (Ground). The Masterpiece must be
earthed.
ANALOGUE OUTPUT DIN SOCKETS - The first 36 of the 108 channels are available here as 0-10v analogue
signals. There are 6 DIN sockets, 6 channels each. Pin connections: Pin 1 not used, 2 = earth (ground),
3-8 = channels 1-6, 7-12, etc. - as printed on the back panel.
The outputs are via isolating diodes so they may feed the same equipment as other controllers - the highest taking
priority.
DMX512 DIGITAL OUTPUT 5 PIN XLR SOCKETS - All 108 channels levels are transmitted in the DMX512/1990
serial digital format to any device capable of receiving it. Use twin core screened cable. Pin connections:
Pin 1 = Screen Earth, Pin 2 = Signal-, Pin 3 = .
NOTE: The end of the DMX line MUST ALWAYS be terminated with a 100 ohm resistor connected between
and Signal-. This resistor can conveniently be mounted in a 5 pin XLR plug which should be inserted in
the last device on the DMX line.
RS232 DIGITAL OUTPUT 3 PIN XLR SOCKETS - All 108 channels levels are transmitted in Pulsar’s RS232
serial digital format (full details in Appendix 1) to any device capable of receiving it which include Clay Paky
Intelligent Spotlights, Pulsar Universal Interfaces for conversion to 0-10v analogue channels, 36 channels per
Interface, computers etc.
Pin 1 = Earth, Pins 2 and 3 = signal. Use single core screened cable.
This data stream also contains key press and slider move information to drive a slave Masterpiece.
* RS232 DIGITAL INPUT/OUTPUT 3 PIN XLR SOCKETS
For use by Slave Masterpieces. The signal from the Master Masterpiece or the previous Slave Masterpiece
enters here and may link on to another Slave or proceed to the lights or other receiving equipment. A computer
could control the Masterpiece remotely via this input - see Appendix 2 protocol.
Pin 1 = Earth, Pins 2 and 3 = signal. Use single core screened cable.
AUDIO INPUT SOCKETS
1. One Microphone 1/4" mono jack socket
2. Two Pre-amp level (0.1v - 2.5v RMS) 1/4" stereo jack sockets (in/out)
3. Two Hi level (2.5v - 100v RMS) 1/4" stereo jack sockets (in/out)
Please note, when feeding a signal from a stereo system, both left and right audio signals must be supplied to the
Masterpiece to produce faithful Sound-to-Light.
* MIDI IN - for total remote control of ANY Touch Pad or Slider.
See Appendix 3 for protocol.
MIDI THRU - retransmits the MIDI IN signal to the next device in the MIDI signal chain.
* MIDI SELECTOR SWITCH
* REMOTE CONTROL DIN SOCKET - for Environments and Environment Chases.
* This feature will be available in future software upgrades.
